View and manage general IPv6 information.
Procedure
-
Display IPv6 information for an interface:
show ipv6 interface [gigabitethernet {slot/port[/sub-port] [-slot/port[/sub-port]] [,...]}] [loopback <1-256>][mgmtEthernet {slot/port[/sub-port][-slot/port[/sub-port]][,...]}][tunnel <1–2000>][vlan <1-4059>] [vrf WORD<1–16>] [vrfids WORD<0-512>]
Note
The mgmtEthernet parameter is only supported on VSP 8600 Series.
-
Display IPv6 router
advertisement information for the management port:
show ipv6 nd interface mgmtEthernet mgmt
Note
This step applies to VSP 8600 Series only.

Variable definitions
Use the data in the following table to use the show ipv6 commands.
|
Variable |
Value |
|---|---|
|
address interface ip WORD<0-46> |
Specifies the IPv6 address. |
|
neighbor [WORD<0-46>] |
Specifies the IPv6 address of the neighbor. |
|
loopback <1-256> |
Specifies the loopback interface ID value. If you do not specify a value, the output includes all IPv6 loopback interfaces. |
|
{slot/port[/sub-port][-slot/port[/sub-port]][,...]} |
Identifies the slot and port in one of the following formats: a single slot and port (slot/port), a range of slots and ports (slot/port-slot/port), or a series of slots and ports (slot/port,slot/port,slot/port). If the platform supports channelization and the port is channelized, you must also specify the sub-port in the format slot/port/sub-port. |
|
type <1–4> |
Specifies the neighbor type as one of the following:
|
|
tunnel <1–2000> |
Specifies the tunnel ID. |
|
vlan <1-4059> |
Specifies the VLAN ID in the range of 1 to 4059. By default, VLAN IDs 1 to 4059 are configurable and the system reserves VLAN IDs 4060 to 4094 for internal use. On switches that support the vrf-scaling and spbm-config-mode boot configuration flags, if you enable these flags, the system also reserves VLAN IDs 3500 to 3998. VLAN ID 1 is the default VLAN and you cannot create or delete VLAN ID 1. |
|
vrfWORD<1–16> |
Specifies the VRF name. |
|
vrfidsWORD<1–256> |
Specifies the VRF ID. |
