  3. Display IPv6 tunnel information:

    show ipv6 interface tunnel <1-2000>

  4. Display IPv6 address information for the specified slot and port:

    show ipv6 address interface gigabitethernet {slot/port[/sub-port] [-slot/port[/sub-port]] [,...]} [vrf WORD<1–16>] [vrfids WORD<0-512>]

  5. Display IPv6 address information for the specified IPv6 address:

    show ipv6 address interface ip WORD<0-46> [vrf WORD<1–16>] [vrfids WORD<0-512>]

  6. Display IPv6 address information for the specified tunnel:

    show ipv6 address interface tunnel <1–2000>

  7. Display IPv6 address information for the specified VLAN:

    show ipv6 address interface vlan <1-4059>

  8. Display the current state of IPv6 forwarding:

    show ipv6 forwarding [vrf WORD<1–16>] [vrfids WORD<0-512>]

  9. Display information on the current state of IPv6 functionality:

    show ipv6 global [vrf WORD<1–16>] [vrfids WORD<0-512>]

  10. Display IPv6 Gigabit Ethernet (GbE) router advertisement information:

    show ipv6 nd interface gigabitethernet [{slot/port[-slot/port][,...]}]

  11. Display IPv6 Gigabit Ethernet (GbE) router advertisement information:

    show ipv6 nd interface gigabitethernet [{slot/port[/sub-port] [-slot/port[/sub-port]] [,...]}]

  12. Display IPv6 VLAN router advertisement information:

    show ipv6 nd interface vlan [<1-4059>]

  13. Display detailed information in IPv6 router advertisements:

    show ipv6 nd-prefix detail [vrf WORD<1–16> | vrfids WORD<0–512>]

  14. Display GbE interface information in IPv6 router advertisements:

    show ipv6 nd-prefix interface gigabitethernet [{slot/port[-slot/port][,...]}]

  15. Display GbE interface information in IPv6 router advertisements:

    show ipv6 nd-prefix interface gigabitethernet [{slot/port[/sub-port] [-slot/port[/sub-port]] [,...]}]

  16. Display VLAN interface information in IPv6 router advertisements:

    show ipv6 nd-prefix interface vlan [<1-4059>]

  17. Display VLAN information in IPv6 router advertisements:

    show ipv6 nd-prefix vlan <1-4059>

  18. Display IPv6 neighbor entries with specific brouter port numbers:

    show ipv6 neighbor interface gigabitethernet {slot/port[/sub-port]}

  19. Display IPv6 neighbor information for neighbors of the specified type:

    show ipv6 neighbor type <1–4>

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:

  • 1 - other

  • 2 - dynamic

  • 3 - static

  • 4 - local

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.
