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 47 lists the show ipv6 traffic command output fields.

Table 47: show ipv6 traffic Output Fields

Field Name	Field Description
IPv6 statistics Rcvd	total—Total number of packets received local destination—Number of packets received with this router as their destination hdr errors—Number of packets containing header errors addr errors—Number of packets containing addressing errors unkn proto—Number of packets received containing unknown protocols discards—Number of discarded packets
IPv6 statistics Sent	forwarded—Number of packets forwarded generated—Number of packets generated out disc—Number of packets that could not be routed that were discarded
IPv6 statistics Mcast	received—Number of multicast packets received forwarded—Number of multicast packets forwarded
IPv6 statistics (Routes)	Number of routes currently in the routing table
ICMPv6 statistics Rcvd	total—Total number of received packets errors—Error packets received destination unreach—Packets received with destination unreachable admin unreach—Packets received because the destination was administratively unreachable (for example, the packet encountered a firewall filter) parameter problem—Packets received with parameter errors time exceeded—Packets received with time-to-live exceeded pkt too big—Number of packet-too-big messages received that indicate a packet was too large to forward because of the allowed MTU size redirects—Received packet redirects echo requests—Echo request (ping) packets echo replies—Echo replies received rtr solicits—Number of received router solicitations rtr advertisements—Number of received router advertisements neighbor solicits—Number of received neighbor solicitations neighbor advertisements—Number of received neighbor advertisements Group membership (queries, responses, reductions)—Number of queries, responses, and reduction requests received from within a group to which the interface is assigned
ICMP statistics Sent	total—Total number of received packets errors—Error packets received destination unreach—Packets received with destination unreachable admin unreach—Packets sent because the destination was administratively unreachable (for example, due to a firewall filter) parameter problem—Packets received with parameter errors time exceeded—Packets received with time-to-live exceeded pkt too big—Number of packet-too-big messages sent because a received packet was too large to forward because of the allowed MTU size redirects—Received packet redirects echo requests—Echo request (ping) packets echo replies—Echo replies received rtr solicits—Number of sent router solicitations rtr advertisements—Number of sent router advertisements neighbor solicits—Number of sent neighbor solicitations neighbor advertisements—Number of sent neighbor advertisements Group membership (queries, responses, reductions)—Number of queries, responses, and reduction requests sent to a group to which the interface is assigned
UDP Statistics Rcvd	total—Total number of received packets checksum errors—Checksum error packets received no port—No port error packets received
UDP Statistics Sent	total—Total number of received packets errors—Error packets received
