Monitoring IPv6 Traffic Statistics
Purpose
Display statistics about IPv6 traffic.
 | - 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

host1#show ipv6 traffic

Table 1 lists the show ipv6 traffic command output fields.
Table 1: 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
