Configuring Node Alias

Setting up Node Alias takes two steps:
  1. Enabling (or disabling) Node Alias on port(s):
    Note

    Note

    By default, Node Alias is disabled on all ports.
    Note

    Note

    Node Alias should be separately enabled/disabled on a LAG (Link Aggregation Group) ports.

    enable nodealias ports [port_list | all]

    disable nodealias ports [port_list | all]

  2. Enabling (or disabling) certain protocols for Node Alias to snoop:
    Note

    Note

    By default, Node Alias is enabled to capture all of the following supported protocols: IPv4, IPv6, OSPF, BGP (Border Gateway Protocol), VRRP (Virtual Router Redundancy Protocol), DHCPS, DHCPC, BOOTPS, BOOTPC, UDP, BPDU, LLMNR, SSDP, and mDNS.

    enable nodealias protocol [protocol_name | all]

    disable nodealias protocol [protocol_name | any]

To modify the per-port maximum number of alias entries in the Node Alias database, use the following command:

configure nodealias ports [port_list |all] maxentries entries

To show Node Alias information, use the following commands:

show nodealias

show nodealias ports {port_list| all}

show nodealias mac mac_address {protocol protocol_name | ports [port_list | all]}

show nodealias ip ip_address

show nodealias protocol protocol_name

To clear node alias entries out of the Node Alias feature database by specified port(s) or alias ID, use the following command:

clear nodealias { ports [port_list | all] | alias-id alias_id }
