Clearing IPv6 trac statistics
To clear all IPv6 trac statistics (reset all elds to zero), enter the following command at the Privileged EXEC level or any of the Cong
levels of the CLI.
device(config)#clear ipv6 traffic
Syntax: clear ipv6
trac
Displaying global IPv6 information
You can display output for the following global IPv6 parameters:
• IPv6 cache
• IPv6 interfaces
• IPv6 neighbors
• IPv6 route table
• Local IPv6 routers
• IPv6 TCP connections and the status of individual connections
• IPv6 trac statistics
Displaying IPv6 cache information
The IPv6 cache contains an IPv6 host table that has indices to the next hop gateway and the router interface on which the route was
learned.
To display IPv6 cache information, enter the following command at any CLI level.
device# show ipv6 cache
Total number of cache entries: 10
IPv6 Address Next Hop Port
1 2001:DB8::2 LOCAL tunnel 2
2 2001:DB8::106 LOCAL ethe 1/3/2
3 2001:DB8::110 DIRECT ethe 1/3/2
4 2001:DB8:46a::1 LOCAL ethe 1/3/2
5 2001:DB8::2e0:52ff:fe99:9737 LOCAL ethe 1/3/2
6 2001:DB8::ffff:ffff:feff:ffff LOCAL loopback 2
7 2001:DB8::c0a8:46a LOCAL tunnel 2
8 2001:DB8::c0a8:46a LOCAL tunnel 6
9 2001:DB8::1 LOCAL loopback 2
10 2001:DB8::2e0:52ff:fe99:9700 LOCAL ethe 1/3/1
Syntax: show ipv6 cache [ index-number |
ipv6-prex/prex-length | ipv6-address | ethernet unit / slot / port | venumber | tunnel
number ]
The index-number parameter restricts the display to the entry for the specied index number and subsequent entries.
The ipv6-prex/prex-length parameter restricts the display to the entries for the specied IPv6 prex. You must specify the ipv6-prex
parameter in hexadecimal using 16-bit values between colons as documented in RFC 2373. You must specify the prex-length
parameter as a decimal value. A slash mark (/) must follow the ipv6-prex parameter and precede the prex-length parameter.
The ethernet | ve | tunnel parameter restricts the display to the entries for the specied interface. The ipv6-address parameter restricts
the display to the entries for the specied IPv6 address. You must specify this parameter in hexadecimal using 16-bit values between
colons as documented in RFC 2373.
