IPv6 Interface
– 763 –
show ipv6 interface This command displays the usability and configured settings for IPv6 interfaces.
Syntax
show ipv6 interface [brief [vlan vlan-id [ipv6-prefix/prefix-length]]]
brief - Displays a brief summary of IPv6 operational status and the
addresses configured for each interface.
vlan-id - VLAN ID (Range: 1-4094)
ipv6-prefix - The IPv6 network portion of the address assigned to the
interface. The prefix must be formatted according to RFC 2373 “IPv6
Addressing Architecture,” using 8 colon-separated 16-bit hexadecimal
values. One double colon may be used in the address to indicate the
appropriate number of zeros required to fill the undefined fields.
prefix-length - A decimal value indicating how many of the contiguous bits
(from the left) of the address comprise the prefix (i.e., the network portion
of the address).
Command Mode
Privileged Exec
