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: 1-4093)
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
