I have been trying to identify the host of an IPv6 address which has shown up on some network reports.
We have an IPv4 native network, so no DHCPv6 etc.
We have a Nortel Switching Stack (Base unit - 5520-24T-PWR & 4 x 5520-48T-PWR). And I have been trying to view the NDP cache, to obtain the MAC address etc. Using the show ipv6 neighbor command (in global config mode) but no joy.
In fact, when I run any of the ipv6 commands (show ipv6 default-gateway, show ipv6 address etc) I get invalid input and the marker points to the v (see screendumps)
Obviously ipv6 commands not recognised. So does this mean the switch doesn't support ipv6? Or has it been disabled? Is there a way to check?
Furthermore, is there another way I can determine what devive this ipv6 address is?
