R211x-HP Flexfabric 11900 Layer 2 - LAN Switching Command Reference

Predefined user roles

network-admin

mdc-admin

Parameters

dynamic: Specifies dynamic MAC address entries.

static: Specifies static MAC address entries.

multiport: Specifies multiport unicast MAC address entries. A frame whose destination MAC address

matches a multiport unicast MAC address entry is sent out of multiple ports.

mac-address: Specifies a MAC address in the format of H-H-H, excluding multicast and all-zero MAC

addresses. When entering a MAC address, you can omit the leading zeros in each H section. For

example, enter f-e2-1 for 000f-00e2-0001.

vlan vlan-id: Specifies an existing VLAN to which the specified interface belongs. The value range for the

vlan-id argument is 1 to 4094.

Usage guidelines

Generally, the device automatically builds the MAC address table by learning the source MAC

addresses of incoming frames on each interface. To improve the security for an interface, you can

manually add the specific MAC address entries to the MAC address table and bind the user device to the

interface. Because manually configured static entries have higher priority than dynamically learned

entries, using manually configured entries prevents hackers from using forged MAC addresses to steal

data.

The MAC address entries configuration cannot survive a reboot unless you save it. The dynamic MAC

address entries, however, are lost upon reboot regardless of whether you save the configuration.

This command displays manually configured dynamic MAC address entries for an aggregate interface

only when at least one member port is in Selected state.

Examples

# Add a static entry for MAC address 000f-e201-0101 on interface Ten-GigabitEthernet 1/0/1 that

belongs to VLAN 2.

<Sysname> system-view

[Sysname] interface ten-gigabitethernet 1/0/1

[Sysname-Ten-GigabitEthernet1/0/1] mac-address static 000f-e201-0101 vlan 2

# Add a static entry for MAC address 000f-e201-0101 on Layer 2 aggregate interface

Bridge-Aggregation 1 that belongs to VLAN 1.

<Sysname> system-view

[Sysname] interface bridge-aggregation 1

[Sysname-Bridge-Aggregation1] mac-address static 000f-e201-0102 vlan 1

# Add a static entry for MAC address 000f-e201-0102 on interface S-Channel 1/0/1:10 that belongs to

VLAN 1.

belongs to VLAN 1.
