Displaying IPv6 session flows
If you want to display the contents of an IPv6 session cache, enter the following command.
BigIron RX# show ipv6 flows
Syntax: show ipv6 flows [< source-ipv6-prefix/prefix-length > | any | host < source-ipv6_address >
< destination-ipv6-prefix/prefix-length > | any | host < destination-ipv6-address >]
If you do not specify a source or destination, all IPv6 flows are displayed.
Enter a value for < source-ipv6-prefix >/< prefix-length > or < destination-ipv6-prefix >/< prefix-length >
to specify a source or destination prefix and prefix length that a flow must match to be included in
the display.
Enter any for source or destination if a flow can have any source or any destination to be included in
the display.
The host < source-ipv6-address > and host < destination-ipv6-address > parameters allow you
specify a source or destination host IPv6 address that a flow must match to be included in the
display.
