Page 25: Flow-Interval
mdc-admin Usage guidelines To implement flow control on a link, enable the generic flow control function at both ends of the link. TxRx mode generic flow control enables an Ethernet interface to receive common pause frames from its peer, and send common pause frames to notify its peer of congestions. With the flow-control command configured, an interface can both send and receive flow control frames: When congested, the interface sends a flow control frame to its peer. -

Predefined user roles network-admin mdc-admin Parameters value: Sets the maximum length of Ethernet frames that are allowed to pass through. The value range for the argument is 1552 to 9216. On LST1XP16LEB1 and LST1XP16LEC1 cards, the value range for the argument is 1552 to 8168. -
Page 28: Loopback
When the interface goes up, the link-up event is immediately reported. • With the link-delay delay-time mode up command configured: When the interface goes up, the link-up event is not reported to the CPU unless the interface is still • up when the suppression interval (delay-time) expires. -
Page 29: Port Link-Mode
An Ethernet interface in a loopback test does not forward data traffic. On a physically down interface (displayed as in DOWN state), you can only perform an internal loopback test, and an external loopback test will fail. On an administratively shut down interface (displayed as in ADM or Administratively DOWN state), you cannot perform an internal or external loopback test. -
Page 30: Port-Mode
The following Ethernet interfaces do not support switching the operating mode: aggregation group member ports, reflector port of a remote source mirroring group, and Ethernet interfaces of a switch operating in IRF mode and with enhanced IRF enabled. For more information about reflector ports, see Network Management and Monitoring Configuration Guide. -

Views Layer 2 Ethernet interface view Predefined user roles network-admin mdc-admin Parameters ratio: Sets the broadcast suppression threshold as a percentage of the maximum interface rate. The value range for the argument is 0 to 100. The smaller the percentage, the less broadcast traffic is allowed to pass through. -

is allowed to pass through. The argument is always 100. As a result, you cannot suppression multicast traffic by using the argument. pps max-pps: Specifies the maximum number of multicast packets that the interface can forward per second. The value range for the max-pps argument (in pps) is 1 to 1.4881 × the maximum interface rate. For example, the value range for the argument is 1 to 1488100 on a GE interface. -
Page 37: Unicast-Suppression
Only 10-GE fiber ports operating in LAN mode and GE fiber ports support this command. Copper ports and combo interfaces do not support this command. To configure this command on a port, make sure the port is operating in bridge mode. The port up-mode command is mutually exclusive with any of the shutdown, speed, duplex, and loopback commands. -
Page 38: Layer 3 Ethernet Interface Or Subinterface Commands
Usage guidelines You can use the unicast storm suppression function to limit the size of unicast traffic on an interface. When the unicast traffic on the interface exceeds this threshold, the system discards packets until the unicast traffic drops below this threshold. When you configure the suppression threshold in pps or kbps, the device converts the configured value into a multiple of a certain step (6400 for pps and 50 for kbps) supported by the chip. - Page 39 Examples # Set the MTU to 1430 bytes for Layer 3 Ethernet interface GigabitEthernet 3/0/1. <Sysname> system-view [Sysname] interface GigabitEthernet 3/0/1 [Sysname-GigabitEthernet3/0/1] mtu 1430 # Set the MTU to 1400 bytes for Layer 3 Ethernet subinterface GigabitEthernet 3/0/1.1. <Sysname> system-view [Sysname] interface GigabitEthernet 3/0/1.1 [Sysname-GigabitEthernet3/0/1.1] mtu 1430...

If the loopback keyword is not specified, the command displays information about all interfaces of the device. If the loopback keyword is specified but the interface-number argument is not specified, the command displays information about all existing loopback interfaces.

than 27 characters. When the keyword is specified, all characters of the interface description are displayed. Usage guidelines The device has only one null interface (Null 0). The null interface number is fixed at 0. If the null keyword is not specified, the command displays information about all interfaces of the device. If the null keyword is specified but the 0 keyword is not specified, the command displays information about interface Null 0, because the device has only one null interface Null 0. -

Page 48: Shutdown
Parameters 0: Specifies the number of the null interface, which is fixed at 0. Usage guidelines To determine whether the null interface works correctly within a period by collecting the traffic statistics within that period, first use the reset counters interface [ null [ 0 ] ] command to clear the statistics, and then have the interface automatically collect the statistics. -

Bulk interface configuration commands interface range Use interface range to create an interface range and enter the interface range view. Syntax interface range interface-list Views System view Predefined user roles network-admin mdc-admin Parameters interface-list: Specifies an interface list in the format of interface-list = { interface-type interface-number [ to interface-type interface-number ] }&<1-5>. -

Use interface range name name without the interface keyword to enter the view of an interface range with the specified name. - Page 51 The maximum number of interface range names is only limited by the system resources. To • guarantee bulk interface configuration performance, H3C recommends configuring fewer than 1000 interface range names. Examples # Add GigabitEthernet 3/0/1 through GigabitEthernet 3/0/12 to interface range named myEthPort, and enter the interface range view.
