Use this command to display configured entries in the IPv6 neighbor discovery cache.
| ipv6-address | (Optional) Specifies the IPv6 address to display. |
| group | (Optional) Displays neighbor entries in groups of 5, delineated by a line-break. |
| interface interface | (Optional) Specifies that only entries for the specified interface should display. |
| verbose | (Optional) Specifies that additional information should display regardless of terminal column size. |
| statistics | (Optional) Specifies that various IPv6 neighbor cache statistics should display. |
If ipv6-address is not specified, all IPv6 address entries will display.
If group is not specified, all interfaces are displayed without line-breaks.
If interface interface is not specified, all interfaces will display.
If verbose is not specified, the default level of data based upon options specified will display.
If statistics is not specified, entry information will display.
All command modes.
The following example shows how to display information for all learned IPv6 neighbor entries in the neighbor discovery cache:

FLAGS: I = Incomplete R = Reachable
S = Stale D = Delay
P = Probe L = Local
F = Fixed (Static) H = Host Interest
V = VRRP 2 = Secondary VLAN
Note: Additional information is available by using the 'verbose' option or by
increasing the size of your terminal columns to 111 (use 'set width')

| Output... | What it displays... |
|---|---|
| IPv6 address | An IPv6 address of a neighbor entry. |
| Hardware Address | The MAC address of an IPv6 neighbor entry. |
| Flg | Zero or more flags associated with an IPv6 neighbor entry:
|
| Age | The length of time this entry has existed. |
| Updated | The length of time since the last update for this entry. |
| Expire | The length of time before this entry moves from its current state to the next state. |
| Interface | The interface the ARP entry is assigned to. |
| Port | The host port for this entry. |
