  • Page 27: Chapter 2 Time Protocols

    Chapter 2 Time Protocols NOTE: For successful time protocol setup and specific configuration details, you may need to contact your system administrator regarding your local configuration. General steps for running a time protocol on the switch Using time synchronization ensures a uniform time among interoperating devices. This helps you to manage and troubleshoot switch operation by attaching meaningful time data to event and error messages.
  • Page 28: Ntp Time Synchronization

    security over the Broadcast mode by specifying which time server to use instead of using the first one detected through a broadcast. NTP time synchronization The Network Time Protocol (NTP) synchronizes the time of day among a set of distributed time servers and clients in order to correlate events when receiving system logs and other time-specific events from multiple network devices.
  • Page 29: Disabling Time Synchronization

    The switch retains the parameter settings for both time protocols even if you change from one protocol to the other. Thus, if you select a time protocol, the switch uses the parameters you last configured for the selected protocol. Simply selecting a time synchronization protocol does not enable that protocol on the switch unless you also enable the protocol itself (step 2, above).
  • Page 30 If you configure the switch with TimeP as the time synchronization method, then enable TimeP in DHCP mode with the default poll interval, show timep lists the following: TimeP configuration when TimeP is the selected Time synchronization method switch(config)# show timep Timep Configuration Time Sync Mode: Timep TimeP Mode [Disabled] : DHCP...
  • Page 31: Configuring (Enabling Or Disabling) The Timep Mode

    Configuring (enabling or disabling) the TimeP mode Enabling the TimeP mode means to configure it for either broadcast or unicast mode. Remember to run TimeP as the switch's time synchronization protocol, you must also select TimeP as the time synchronization method by using the CLI timesync command.
  • Page 32 Selects TimeP as the time synchronization method. Syntax: ip timep dhcp Configures DHCP as the TimeP mode. For example, suppose: • Time Synchronization is configured for SNTP. • You want to: ◦ View the current time synchronization. ◦ Select TimeP as the synchronization mode. ◦...

  • Page 34: Sntp: Selecting And Configuring

    Disabling the TimeP mode Syntax: no ip timep Disables TimeP by changing the TimeP mode configuration to Disabled and prevents the switch from using it as the time synchronization protocol, even if it is the selected Time Sync Method option. Example: If the switch is running TimeP in DHCP mode, no ip timep changes the TimeP configuration as shown below and disables time synchronization.
  • Page 35: Viewing And Configuring Sntp (Cli)

    SNTP parameter Operation Server Address Used only when the SNTP Mode is set to Unicast. Specifies the IP address of the SNTP server that the switch accesses for time synchronization updates. You can configure up to three servers; one using the menu or CLI, and two more using the CLI. Server Version Specifies the SNTP software version to use and is assigned on a per-server basis.
  • Page 36: Configuring (Enabling Or Disabling) The Sntp Mode

    Priority SNTP Server Address Protocol Version -------- ------------------------------ ---------------- 2001:db8::215:60ff:fe79:8980 10.255.5.24 fe80::123%vlan10 Syntax: show management This command can help you to easily examine and compare the IP addressing on the switch. It lists the IP addresses for all time servers configured on the switch, plus the IP addresses and default gateway for all VLANs configured on the switch.
  • Page 37 Syntax: sntp server priority <1-3> Specifies the order in which the configured servers are polled for getting the time. Value is between 1 and 3. Syntax: sntp <30-720> Configures the amount of time between updates of the system clock via SNTP. Default: 720 seconds Enabling SNTP in Broadcast Mode Because the switch provides an SNTP polling interval (default: 720 seconds), you need only these two commands...

  • Page 41 Disabling time synchronization without changing the SNTP configuration (CLI) The recommended method for disabling time synchronization is to use the timesync command. Syntax: no timesync Halts time synchronization without changing your SNTP configuration. Example: Suppose SNTP is running as the switch's time synchronization protocol, with broadcast as the SNTP mode and the factory-default polling interval.
  • Page 42: Sntp Client Authentication

    Note that even though the Time Sync Mode is set to Sntp, time synchronization is disabled because no sntp has disabled the SNTP Mode parameter. SNTP client authentication Enabling SNTP authentication allows network devices such as switches to validate the SNTP messages received from an NTP or SNTP server before updating the network time.
  • Page 43: Configuring A Trusted Key

    Syntax: sntp authentication key-id <key-id> authentication-mode <md5> key-value <key-string> [trusted] no sntp authentication key-id <key-id> Configures a key-id, authentication-mode (MD5 only), and key-value, which are required for authentication. The no version of the command deletes the authentication key. Default: No default keys are configured on the switch. key-id A numeric key identifier in the range of 1-4,294,967,295 (2 ) that identifies the unique key value.
  • Page 44: Associating A Key With An Sntp Server (Cli)

    Trusted keys are used during the authentication process. You can configure the switch with up to eight sets of key-id/key-value pairs. One specific set must selected for authentication; this is done by configuring the set as trusted. The key-id itself must already be configured on the switch. To enable authentication, at least one key-id must be configured as trusted.
  • Page 45: Configuring Unicast And Broadcast Mode For Authentication

    Configuring unicast and broadcast mode for authentication To enable authentication, you must configure either unicast or broadcast mode. When authentication is enabled, changing the mode from unicast to broadcast or vice versa is not allowed; you must disable authentication and then change the mode.
  • Page 46: Saving Configuration Files And The Include-Credentials Command

    Viewing all SNTP authentication keys that have been configured on the switch (CLI) Enter the show sntp authentication command, as shown in Show sntp authentication command output on page 46.

To configure a second and third address, you must use the CLI.
  • Page 50: Commands

    Before synchronizing, NTP compares the time reported by several network devices and does not synchronize with one that is significantly different, even if it is a stratum 1. The security features of NTP can be used to avoid the accidental or malicious setting of incorrect time. One such mechanism is available: an encrypted authentication mechanism.

  • Page 156: Operating Notes For Rate-Limiting

    Operating notes for rate-limiting • Rate-limiting operates on a per-port basis, regardless of traffic priority. Rate-limiting is available on all types of ports (other than trunked ports) and at all port speeds configurable for these switches. • Rate-limiting on a trunk is not allowed for the all, bcast, icmp, and mcast traffic types. Rate-limiting is not supported on ports configured in a trunk group (including mesh ports).
  • Page 157: Icmp Rate-Limiting

    NOTE: Rate-limiting is applied to the available bandwidth on a port and not to any specific applications running through the port. If the total bandwidth requested by all applications is less than the configured maximum rate, then no rate-limit can be applied. This situation occurs with a number of popular throughput-testing applications, as well as most regular network applications.
  • Page 158: Guidelines For Configuring Icmp Rate-Limiting

    NOTE: ICMP rate-limiting does not throttle non-ICMP traffic. In cases where you want to throttle both ICMP traffic and all other inbound traffic on a given interface, you can separately configure both ICMP rate- limiting and all-traffic rate-limiting. The all-traffic rate-limiting command (rate-limit all) and the ICMP rate-limiting command (rate-limit icmp) operate differently: •...

Causes an interface to drop all incoming ICMP traffic and is not recommended. See the caution.
  • Page 160: Viewing The Current Icmp Rate-Limit Configuration

    • Inbound ICMP traffic on port "X" is using 1% of the port's bandwidth, and • Inbound traffic of all types on port "X" demands 61% of the ports's bandwidth, all inbound traffic above 55% of the port's bandwidth, including any additional ICMP traffic, is dropped as long as all inbound traffic combined on the port demands 55% or more of the port's bandwidth.
  • Page 161: Icmp Rate-Limiting Trap And Event Log Messages

    • ICMP percentage-based rate-limits are calculated as a percentage of the negotiated link speed: For example, if a 100 Mbps port negotiates a link to another switch at 100 Mbps and is ICMP rate-limit configured at 5%, the inbound ICMP traffic flow through that port is limited to 5 Mbps. Similarly, if the same port negotiates a 10 Mbps link, it allows 0.5 Mbps of inbound traffic.

    Syntax: interface <port-list> rate-limit icmp trap-clear On a port configured with ICMP rate-limiting, this command resets the ICMP trap function, which allows the switch to generate a new SNMP trap and an Event Log message if ICMP traffic in excess of the configured limit is detected on the port.

    ◦ Transceiver type not supported in this software version. ◦ Not an Switch Transceiver. Guaranteed minimum bandwidth (GMB) GMB provides a method for ensuring that each of a given port's outbound traffic priority queues has a specified minimum consideration for sending traffic out on the link to another device. This can prevent a condition where applications generating lower-priority traffic in the network are frequently or continually "starved"...
  • Page 166: Impacts Of Qos Queue Configuration On Gmb Operation

    Since the switch services outbound traffic according to priority (highest to lowest), the highest-priority outbound traffic on a given port automatically receives the first priority in servicing. Thus, in most applications, it is necessary only to specify the minimum bandwidth you want to allocate to the lower priority queues. In this case, the high-priority traffic automatically receives all unassigned bandwidth without starving the lower-priority queues.
  • Page 167: Configuring Gmb For Outbound Traffic

    Configuring GMB for outbound traffic For any port, group of ports, or static trunk, you can configure either the default minimum bandwidth settings for each outbound priority queue or a customized bandwidth allocation. For most applications, Hewlett Packard Enterprise recommends configuring GMB with the same values on all ports on the switch so that the outbound traffic profile is consistent for all outbound traffic.

    LLDP-MED (media-endpoint-discovery) LLDP-MED (ANSI/TIA-1057/D6) extends the LLDP (IEEE 802.1AB) industry standard to support advanced features on the network edge for Voice Over IP (VoIP) endpoint devices with specialized capabilities and LLDP- MED standards-based functionality. LLDP-MED in the switches uses the standard LLDP commands described earlier in this section, with some extensions, and also introduces new commands unique to LLDP-MED operation.

    NOTE: LLDP-MED operation also requires the port speed and duplex TLV (dot3TlvEnable), which is enabled in the default configuration. Topology change notifications provide one method for monitoring system activity. However, because SNMP normally employs UDP, which does not guarantee datagram delivery, topology change notification should not be relied upon as the sole method for monitoring critical endpoint device connectivity.

    Chapter 8 DHCPv4 server Overview The Dynamic Host Configuration Protocol (DHCP) is a network protocol that enables a server to automate assignment of IP addresses to hosts. A DHCP server can be configured to provide other network information like IP addresses of TFTP servers, DNS server, boot file name and vendor specific options. Commonly there are two types of address assignments, dynamic and manual.

    Authoritative pools To process the DHCPINFORM packets received from a client within the given IP pool, a DHCP server has to be configured as authoritative for that IP pool. The server is the sole authority for this IP pool so when a client requests an IP address lease where the server is authoritative, and the server has no record of that IP address, the server will respond with DHCPNAK message which indicates that the client should no longer use that IP address.

    CAUTION: Although the switch supports the use of UDP port numbers from 1 to 65535, UDP port numbers below 7933 are reserved for various IP applications. Using these port numbers for mirroring can result in an interruption of other IP functions, and in non-mirrored traffic being received on the destination (endpoint) switch and sent to the device connected to the remote exit port.
  • Page 432: Configure The Monitored Traffic In A Mirror Session

    CAUTION: After you configure a mirroring session with traffic-selection criteria and a destination, the switch immediately starts to mirror traffic to the destination device connected to each exit port. In a remote mirroring session that uses IPv4 encapsulation, if the remote (endpoint) switch is not already configured as the destination for the session, its performance may be adversely affected by the stream of mirrored traffic.

    • Up to 320 different MAC addresses are supported for traffic selection in all mirroring sessions configured on the switch. • A destination MAC address is not supported as mirroring criteria for routed traffic, because in routed packets, the destination MAC address is changed to the next-hop address when the packet is forwarded. Therefore, the destination MAC address that you want to mirror will not appear in routed packet headers.

  • Page 641 A heartbeat failure triggers the switch to: • Remove users anchored to the SAC. • Fail over to the s-SAC (Example: s-SAC now becomes the new SAC). What happens when the keepalive to a UAC fails? The users anchored to the UAC are removed and a message is logged to the same effect in the event log. Why should jumbo frames be enabled at the switch? Jumbo frames have to be enabled at the controller uplink VLAN as well as the client VLAN.
  • Page 642 A rebootstrap is initiated for users applied within that role containing updated role attributes in the bootstrap packet. These users move to registering state. Once an acknowledgment is received from the controller, users then move to registering state. This applies only to VLAN and secondary role changes. What happens on a client “MAC address move”? A rebootstrap is initiated for the client.
  • Page 643: Chapter 19 Cable Diagnostics

    Chapter 19 Cable Diagnostics The Time Domain Reflectometry (TDR) or Cable Diagnostics is a port feature supported on some switches running ArubaOS-Switch software. TDR is used to detect cable faults on 100BASE-TX and 1000BASE-T ports. Virtual cable testing The Virtual Cable Test (VCT) uses the same command as TDR. It is applicable only for GigT transceivers like copper transceiver (J8177C–ProCurve Gigabit 1000Base-T Mini-GBIC).
