Enable an Existing IP Interface

If the IP address for an existing IP interface is changed, the change to the address is treated as a deletion of one of the management addresses and an addition of a new management address by LLDP. Note that in the following instructions, VLAN 2 is configured with IP address and is enabled for the extreme-ethernet interface 0/1.

  1. At switch 1, change the IP address of VLAN 2 to
    SEFOS# configure terminal
    SEFOS(config)# interface vlan 2
    SEFOS(config-if)# shutdown
    SEFOS(config-if)# ip address
    SEFOS(config-if)# no shutdown
    SEFOS(config-if)# end

    The following list describes the impact of the change in the IP address:

    • The entry corresponding to the old IP address of VLAN 2 is deleted from the LLDP management address table.

    • The entry corresponding to is created.

    • The TLV transmission status of is disabled by default.

  2. Review the IP addresses that are configured for the system and TLV transmission status of the addresses.
    SEFOS# show lldp local mgmt-addr
    Management Address            TxEnabledPorts
    ------------------            --------------                    Ex0/1

    The TxEnabledPorts value for management address does not display any interfaces. The newly configured IP address, has not advertised through extreme-ethernet interface, Ex0/1, and the entry corresponding to IP address was deleted from the remote table.

  3. At switch 2, review the learned neighbor information on the interface.
    SEFOS# show lldp neighbors extreme-ethernet 0/1 detail
    Management Addresses        :
    IfId        SubType    Address        OID
    ----        -------    -------        ---
    1009        IPv4        1 3 6 1 2 1 2 2 1 1

    The entry corresponding to IP address was removed from the list of management addresses.
