    Monitoring IPv6 Traffic Statistics

    Purpose

    Display statistics about IPv6 traffic.

    Note:

    • You must configure an IPv6 license using the license ipv6 command before using the IPv6 routing protocol configuration commands on the E Series router.
    • All IPv6 routing protocol-related configurations are removed from the virtual router when you issue the no ipv6 command.

    Action

    To display statistics about IPv6 traffic:

    host1#show ipv6 traffic
    IPv6 statistics:
      Rcvd:  0 total, 0 local destination
             0 hdr errors, 0 addr errors
             0 unkn proto, 0 discards
      Sent:  0 forwarded, 0 generated
             0 out disc
      Mcast: 0 received 0 forwarded
      Routes: 7 in routing table
    ICMPv6 statistics:
      Rcvd:  0 total, 0 errors
             0 destination unreach, 0 admin unreach, 0 parameter problem
             0 time exceeded, 0 pkt too big, 0 redirects
             0 echo requests, 0 echo replies
             0 rtr solicits, 0 rtr advertisements
             0 neighbor solicits, 0 neighbor advertisements
             Group membership: 0 queries, 0 responses, 0 reductions
      Sent:  3 total, 0 errors
             0 destination unreach, 0 admin unreach, 0 parameter problem
             0 time exceeded, 0 pkt too big, 0 redirects
             0 echo requests, 0 echo replies
             0 rtr solicits, 0 rtr advertisements
             2 neighbor solicits, 1 neighbor advertisements
             Group membership: 0 queries, 0 responses, 0 reductions
              
    UDP Statistics:
      Rcvd: 0 total, 0 checksum errors, 0 no port
      Sent: 0 total, 0 errors

    Meaning

    Table 1 lists the show ipv6 traffic command output fields.
