  • Page 102: Loopback

    Ethernet interface loopback testing should be enabled while testing certain functionalities, such as during the initial identification of any network failure. While enabled, Ethernet interface loopback testing will work in full-duplex mode. The interface will return to its original state upon completion of the loopback testing.

  • Page 103: Loopback-Detection Enable

    Use the undo loopback-detection control enable command to restore the default. By default, loopback detection for a Trunk port or Hybrid port is disabled. Note that this command is inapplicable to an Access port as its loopback detection is enabled by default.

  • Page 104: Loopback-Detection Interval-Time

    A Trap message will be sent to the terminal and the corresponding MAC address. If a Trunk port or Hybrid port has been detected with loopback, a Trunk message will be sent to the terminal. If the loopback detection control function is enabled on the port, the port will transit to the loopback detection control state, where the incoming packets of the port are dropped and the outgoing packets of the port are forwarded normally.

  • Page 105: Loopback-Detection Per-Vlan Enable

    Use the undo loopback-detection per-vlan enable command to enable loopback detection in the default VLAN with Trunk ports or Hybrid ports. By default, loopback detection is only enabled in the default VLAN(s) with Trunk ports or Hybrid ports. Note that the loopback-detection per-vlan enable command is not applicable to Access ports.

  • Page 109: Reset Counters Interface

    Description Use the reset counters interface command to clear the statistics of an interface. Before sampling network traffic within a specific period of time on an interface, you need to clear the existing statistics. If neither interface type nor interface number is specified, this command clears the statistics of all the interfaces.

  • Page 110: Speed

    Note that in case of a double Combo port, only one interface (either the optical port or the electrical port) is active at a time. That is, once the optical port is active (after you execute the undo shutdown command), the electrical port will be inactive automatically, and vice versa.

  • Page 111: Speed Auto

    You are recommended to configure the same port rate and duplex mode on two ports connected to each other, for example, set the duplex mode of both ports to auto negotiation or full/half duplex, so as to avoid packet loss.

  • Page 112: Storm-Constrain

    10 and 100 Mbps on one end and 1000 Mbps on the other, the rate negotiation will fail. When the auto-negotiation rate ranges set on the local and peer ends intersect, for example, 10 and 100 Mbps on one end and 100 and 1000 Mbps on the other, the negotiation rate range is the intersection, 100 Mbps.

  • Page 113: Storm-Constrain Control

    For a 1-Gbps port, this value ranges from 1 to 1488100. For a 10-Gbps port, this value ranges from 1 to 14881000. min-pps-values: Lower threshold to be set, in pps. The range of this argument is 1 to max-pps-values. Description Use the storm-constrain command to enable the storm constrain function for specific type of packets and set the upper and lower thresholds.

  • Page 114: Storm-Constrain Enable Log

    Parameters block: Blocks the traffic of a specific type on a port when the traffic detected exceeds the upper threshold. shutdown: Shuts down a port when a type of traffic exceeds the corresponding upper threshold. A port shut down by the storm constrain function stops forwarding all types of packets.

  • Page 115: Storm-Constrain Enable Trap

    Use the storm-constrain enable trap command to enable trap message sending. With trap message sending enabled, the system sends trap messages when traffic reaching a port exceeds the corresponding threshold or the traffic drops down below the lower threshold after exceeding the upper threshold.

If the port is configured not to detect the packet format automatically while it works in the MSTP mode, and if it receives a packet in the format other than the configured format, it will become a designated port and remain in the discarding state to prevent the occurrence of a loop.

  • Page 429: Stp Cost

    200000. Description Use the stp cost command to set the path cost of the port(s) in the specified MSTI or all MSTIs. Use the undo stp cost command to restore the system default. By default, the device automatically calculates the path costs of ports in each MSTI based on the corresponding standard.

  • Page 430: Stp Edged-Port

    Aggregation Configuration in the Access Volume. If you set instance-id to 0, you are setting the path cost of the port in the CIST. The path cost setting of a port can affect the role selection of the port. Setting different path costs for the same port in different MSTIs allows different VLAN traffic flows to be forwarded along different physical links, thus to enable VLAN-based load balancing.

  • Page 431: Stp Loop-Protection

    Aggregation Configuration in the Access Volume. If a port directly connects to a user terminal rather than another device or a shared LAN segment, this port is regarded as an edge port. When the network topology changes, an edge port will not cause a temporary loop.

  • Page 432: Stp Max-Hops

    By default, the maximum number of hops of an MST region is 20. The maximum hops configured in an MST region limit the size of the MST region. In an MST region, the maximum hops configured on the regional root bridge are the maximum hops of this MST region. After a configuration BPDU leaves the root bridge, its hop count is decremented by 1 each time it passes a device.

  • Page 433: Stp Mode

    STP, this port will automatically migrate to the STP-compatible mode. However, if the device running STP is removed, the port will not be able to migrate automatically to the MSTP (or RSTP) mode, but will remain working in the STP-compatible mode. In this case, you can perform an mCheck operation to force the port to migrate to the MSTP (or RSTP) mode.

  • Page 434: Stp No-Agreement-Check

    By default, No Agreement Check is disabled. Note that: Configured in port view, the setting takes effect on the current port only; configured in port group view, the setting takes effect on all ports in the port group. Configured in Layer-2 aggregate port view, the setting takes effect only on the aggregate port.

  • Page 435: Stp Pathcost-Standard

    By default, the legacy standard is used for calculating the default path cost for ports. Note that if you change the standard that the device uses in calculating the default path cost, the port path cost value set through the stp cost command will be invalid.

  • Page 436: Stp Point-To-Point

    802.1T does. The calculation formula is: Path Cost = 200,000,000/link speed (in 100 kbps), where link speed is the sum of the link speed values of the non-blocked ports in the aggregation group.

  • Page 437: Stp Port Priority

    When connecting to a non-point-to-point link, a port is incapable of rapid state transition. If the current port is a Layer-2 aggregate port or if it works in full duplex mode, the link to which the current port connects is a point-to-point link. We recommend that you use the default setting, namely let MSTP detect the link status automatically.

    0 to 31. The minimum value is 0, representing the CIST. priority: Port priority, in the range of 0 to 61440 in steps of 4096, namely you can set up to 16 priority values, such as 0, 4096, 8192…, on the device.

  • Page 440: Stp Region-Configuration

    Use the undo stp region-configuration command to restore the default MST region configurations. By default, the default settings are used for all the three MST region parameters. Namely, the device’s MST region name is the device’s MAC address, all VLANs are mapped to the CIST, and the MSTP revision level is 0.

  • Page 441: Stp Root Secondary

    There is only one root bridge in effect in an MSTI. If two or more devices have been designated to be root bridges of the same MSTI, MSTP will select the device with the lowest MAC address as the root bridge.

  • Page 442: Stp Root-Protection

    You can configure one or more secondary root bridges for each MSTI. When the root bridge of an MSTI fails or is shut down, the secondary root bridge can take over the role of the root bridge of the specified MSTI. If you specify more than one secondary root bridge, the secondary root bridge with the lowest MAC address will become the root bridge.

  • Page 443: Stp Tc-Protection

    2: System level Parameters None Description Use the stp tc-protection enable command to enable the TC-BPDU attack guard function for the device. Use the stp tc-protection disable command to disable the TC-BPDU attack guard function for the device. By default, the TC-BPDU attack guard function is enabled.

  • Page 444: Stp Timer Forward-Delay

    The forward delay timer set on the root bridge determines the time interval of state transition. If the current device is the root bridge, the state transition interval of the device depends on the set forward delay value; for a secondary root bridge, its state transition interval is determined by the forward delay timer set on the root bridge.

  • Page 445: Stp Timer Hello

    The root bridge sends configuration BPDUs at the interval of the hello time set on the device, while secondary root bridges use the hello time set on the root bridge.

  • Page 446: Stp Timer Max-Age

    BPDU has expired based on the configured max age timer; if the current device is not the root bridge of the CIST, it uses the max age timer set on the CIST root bridge. The settings of the hello time, forward delay and max age timers must meet the following formulae: 2 ×...

  • Page 447: Stp Timer-Factor

    After the network topology is stabilized, each non-root-bridge device forwards configuration BPDUs to the surrounding devices at the interval of hello time to check whether any link is faulty. Typically, if a device does not receive a BPDU from the upstream device within nine times the hello time, it will assume that the upstream device has failed and start a new spanning tree calculation process.
  • Page 448 By default, the maximum transmission rate of all ports of the device is 10. Note that: Configured in port view, the setting takes effect on the current port only; configured in port group view, the setting takes effect on all ports in the port group.

    Use the undo rip default-route command to disable the RIP interface from sending a default route. By default, a RIP interface can advertise a default route if the RIP process is configured with default route advertisement. A RIP router configured to advertise a default route will not receive any default routes from RIP neighbors.

  • Page 720: Rip Metricin

    By default, the additional metric of a received route is 0. When a valid RIP route is received, the system adds a metric to it and then installs it into the routing table. Therefore, the metric of the route received on the configured interface is increased. If the sum of the additional metric and the original metric is greater than 16, the metric of the route will be 16.

    The split horizon function is necessary for preventing routing loops. Therefore, you are not recommended to disable it. In special cases, make sure it is necessary to disable the split horizon function. Only the poison reverse function takes effect if both the split horizon and poison reverse functions are enabled. Examples # Enable the split horizon function on VLAN-interface 10.

  • Page 725: Rip Version

    Use the undo rip version command to remove the specified RIP version. By default, no RIP version is configured for an interface, which uses the global RIP version. If the global RIP version is not configured, the interface can only send RIPv1 broadcasts and can receive RIPv1 broadcasts and unicasts, and RIPv2 broadcasts, multicasts and unicasts.

  • Page 726: Silent-Interface (Rip View)

    Specifies an interface by its type and number. Description Use the silent-interface command to disable an interface or all interfaces from sending routing updates. That is, the interface only receives but does not send RIP messages. Use the undo silent-interface command to restore the default.

  • Page 727: Summary

    Use the summary command to enable automatic RIPv2 summarization. Natural masks are used to advertise summary routes so as to reduce the size of routing tables. Use the undo summary command to disable automatic RIPv2 summarization so that all subnet routes can be broadcast.

  • Page 728: Validate-Source-Address

    The suppress timer defines how long a RIP route stays in the suppressed state. When the metric of a route is 16, the route enters the suppressed state. In the suppressed state, only routes which come from the same neighbor and whose metric is less than 16 will be received by the router to replace unreachable routes.

  • Page 729: Version

    Use the undo version command to remove the configured global RIP version. By default, if an interface has a RIP version specified, the RIP version takes effect; if it has no RIP version specified, it can send RIPv1 broadcasts, and receive RIPv1 broadcasts, RIPv1 unicasts, RIPv2 broadcasts, RIPv2 multicasts, and RIPv2 unicasts.
  • Page 730 If no RIP version is specified for the interface and the global version is RIPv1, the interface inherits RIPv1, and it can send RIPv1 broadcasts, and receive RIPv1 broadcasts and unicasts.

    By default, an interface neither belongs to any area nor runs OSPF. You can configure one or multiple interfaces in an area to run OSPF. Note that the interface’s primary IP address must fall into the specified network segment to make the interface run OSPF. If only the interface’s secondary IP address falls into the network segment, the interface cannot run OSPF.

    Use the undo ospf mtu-enable command to restore the default. By default, an interface adds a MTU of 0 into DD packets, that is, no real MTU is added. Note that: After a virtual link is established via a Tunnel, two devices on the link from different vendors may have different MTU values.

  • Page 783: Ospf Timer Dead

    When the network type of an interface is NBMA, you need to use the peer command to specify a neighbor. If only two routers run OSPF on a network segment, you can configure associated interfaces’ network type as P2P. Related commands: ospf dr-priority.

  • Page 784: Ospf Timer Hello

    If an interface receives no hello packet from the neighbor within the dead interval, the interface considers the neighbor down. The dead interval on an interface is at least four times the hello interval. Any two routers attached to the same segment must have the same dead interval.

  • Page 785: Ospf Timer Poll

    The hello interval defaults to 10s for P2P and Broadcast interfaces, and defaults to 30s for P2MP and NBMA interfaces. The shorter the hello interval is, the faster the topology converges and the more resources are consumed. Make sure the hello interval on two neighboring interfaces is the same.

  • Page 786: Ospf Timer Retransmit

    Use the undo ospf timer retransmit command to restore the default. The interval defaults to 5s. After sending an LSA, an interface waits for an acknowledgement packet. If the interface receives no acknowledgement within the retransmission interval, it will retransmit the LSA.
  • Page 787 The delay defaults to 1s. Each LSA in the LSDB has an age that is incremented by 1 every second, but the age does not change during transmission. It is necessary to add a transmission delay into its age time, which is important for low speed networks.

  • Page 791: Silent-Interface (Ospf View)

    By default, an interface sends OSPF packets. A disabled interface is a passive interface, which cannot send any hello packet. To make no routing information obtained by other routers on a network segment, you can use this command to disable the interface from sending OSPF packets.
  • Page 792 Virtual interface neighbor state change information. Description Use the snmp-agent trap enable ospf command to enable the sending of SNMP traps for a specified OSPF process. If no process is specified, the feature is enabled for all processes. Use the undo snmp-agent trap enable ospf command to disable the feature.

  • Page 793: Stub (Ospf Area View)

    The interval defaults to 5 seconds. Based on its LSDB, an OSPF router calculates the shortest path tree with itself being the root, and uses it to determine the next hop to a destination. Through adjusting the SPF calculation interval, you can protect bandwidth and router resources from being over-consumed due to frequent network changes.
  • Page 794 Note that, to concel the no-summary configuration on the ABR, simply execute the stub command again to overwrite it. To configure an area as a stub area, all routers attached to it must be configured with this command. Related commands: default-cost.
  • Page 795 A value of 1, 2 or 4 means a point-to-point link, a link to a transit network or a virtual link; in such cases, a maximum cost value of 65535 is used.

  • Page 797 The smaller the hello interval is, the faster the network converges and the more network resources are consumed. A so small retransmission interval will lead to unnecessary retransmissions. A big value is appropriate for a low speed link. You need to specify an appropriate transmission delay with the trans-delay keyword.

  • Page 844: Isis Timer Hello

    Level-1 and Level-2 hello packets are sent independently on a broadcast network, so you need to specify an interval for the two levels respectively. On a P2P link, Level-1 and Level-2 packets are both sent in P2P hello packets, and you need not specify an interval for two levels respectively.

  • Page 845: Isis Timer Lsp

    If no level is specified, the hello multiplier applies to the current level. With the IS-IS hello multiplier configured, a router can uses hello packets to notify its neighbor router of the adjacency hold time (hello multiplier times hello interval). If the neighbor router receives no hello packets from this router within the hold time, it declares the adjacency down.

Description Use the ospfv3 network-type command to set the network type for an OSPFv3 interface.

  • Page 991: Ospfv3 Timer Dead

    Use the ospfv3 peer command to specify a neighbor and the DR priority of the neighbor. Use the undo ospfv3 peer command to remove the configuration. A router uses the priority set with the ospfv3 peer command to determine whether to send a hello packet to the neighbor rather than for DR election.

  • Page 992: Ospfv3 Timer Hello

    Instance ID of an interface, in the range of 0 to 255, which defaults to 0. Description Use the ospfv3 timer hello command to configure the hello interval for an interface that belongs to an instance. Use the undo ospfv3 timer hello command to restore the default .

  • Page 993: Ospfv3 Timer Retransmit

    Parameters interval: LSA retransmission interval in seconds, ranging from 1 to 65535. instance-id: Instance ID of an interface, in the range of 0 to 255, which defaults to 0. Description Use the ospfv3 timer retransmit command to configure the LSA retransmission interval for an interface in an instance.

  • Page 994: Ospfv3 Timer Poll

    Interface instance ID, in the range 0 to 255. The default is 0. Description Use the ospfv3 timer poll command to set the poll interval on an NBMA interface. Use the undo ospfv3 timer poll command to restore the default value.

  • Page 995: Preference

    The transmission delay defaults to 1s. As LSAs are aged in the LSDB (incremented by 1 every second) but not aged on transmission, it is necessary to add a delay time to the age time before sending a LSA. This configuration is important for low-speed networks.
  • Page 996 Use the preference command to specify a preference for OSPFv3 routes. Use the undo preference command to restore the default. By default, the preference for OSPFv3 internal routes is 10, and that for OSPFv3 external routes is 150. The smaller the value is, the higher the preference is.

  • Page 997: Silent-Interface(Ospfv3 View)

    Use the undo silent-interface command to restore the default. An interface is able to send OSPFv3 packets by default. Multiple processes can disable the same interface from sending OSPFv3 packets, but use of the silent-interface command takes effect only on interfaces enabled with the current process.

  • Page 998: Stub (Ospfv3 Area View)

    The delay interval and hold interval default to 5s and 10s. An OSPFv3 router works out a shortest path tree with itself as root based on the LSDB, and decides on the next hop to a destination network according the tree. Adjusting the SPF calculation interval can restrain bandwidth and router resource from over consumption due to frequent network changes.
  • Page 999 Specifies the neighbor dead time in seconds, ranging from 1 to 32768, with the default as 40. This value must be equal to the dead seconds configured on the virtual link peer, and at least four times the value of hello seconds.
  • Page 1000 OSPFv3 enabled, because parameters such as hello, dead, retransmit and trans-delay are configured in the similar way. Both ends of a virtual link are ABRs that are configured with the vlink-peer command. Examples # Create a virtual link to 10.110.0.3.
