Column Meaning
isRtr Shows if the neighbor is a router. If TRUE, the neighbor is a router; FALSE it is not a router
Neighbor State The state of the neighbor cache entry. Possible values are: Incomplete, Reachable, Stale, Delay,
Probe, and Unknown
Age The time in seconds that has elapsed since an entry was added to the cache.
Last Updated The time in seconds that has elapsed since an entry was added to the cache.
Type The type of neighbor entry. The type is Static if the entry is manually configured and Dynamic if
dynamically resolved.
The following is an example of the command.
(Extreme 220) (Routing) #show serviceport ipv6 neighbors

ping ipv6
Use this command to determine whether another computer is on the network. Ping provides a
synchronous response when initiated from the CLI interface. To use the command, configure the switch
for network (in-band) connection. The source and target devices must have the ping utility enabled and
running on top of TCP/IP. The switch can be pinged from any IP workstation with which the switch is
connected through the default VLAN (VLAN 1), as long as there is a physical path between the switch
and the workstation. The terminal interface sends three pings to the target station. Use the ipv6-
address|hostname parameter to ping an interface by using the global IPv6 address of the interface. Use
the optional size keyword to specify the size of the ping packet. Use the outgoing-interface
option to specify the outgoing interface for a multicast IP/IPv6 ping.
You can utilize the ping or traceroute facilities over the service/network ports when using an IPv6 global
address ipv6-global-address|hostname. Any IPv6 global address or gateway assignments to these
interfaces will cause IPv6 routes to be installed within the IP stack such that the ping or traceroute
request is routed out the service/network port properly. When referencing an IPv6 link-local address,
you must also specify the service or network port interface by using the serviceport or network
parameter.
