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]][,...][slot/all][all]} |
Identifies the
slot and port in one of the following formats:
|
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. |
