MAC Address Snooping on Client Ports

MAC address snooping allows you to learn the MAC address of the neighbor, that is connected to the client

ports. You can enable ARP snooping on all client ports and learn the MAC address of neighbors through CLI.

This feature overcomes the limitation, where LLDP (Link Layer Discovery protocol) cannot be enabled in

some networks.

Limitations

• When you enable or disable MAC address snooping on any slice, few packets are dropped during

configuration.

• Open config interface for enabling or disabling MAC address snooping is not supported.

• SNMP MIB is not supported for the MAC address attribute.

When you enable MAC address snooping on client ports, it overrides LLDP.

Note

Configuring MAC Address Snooping on Client Ports

You can configure MAC address or ARP snoop on slice in Muxponder slice mode using the following

commands.

configure

hw-module location location mxponder-slice slice-number

client-rate 100GE

trunk-rate 600G { 100G | 150G | 200G | 250G | 300G | 350G | 400G | 450G | 500G | 550G | 600G }

Example

The following is a sample in which, MAC address or ARP snoop is configured on the client ports of slice 0

in Muxponder slice mode.

RP/0/RP0/CPU0:ios#configure

RP/0/RP0/CPU0:ios(config)#hw-module location 0/3 mxponder-slice 0

RP/0/RP0/CPU0:ios(config-hwmod-mxp)#client-rate 100GE

RP/0/RP0/CPU0:ios(config-hwmod-mxp)#trunk-rate 600G

RP/0/RP0/CPU0:ios(config-hwmod-mxp)#arp-snoop
