Monitoring Detailed or Summary Information for IPv6 Addresses

Purpose

Display detailed or summary interface information for a particular IPv6 address. You can use the brief keyword to display summary information about the interface for the specified IPv6 address. You can use the detail keyword to display detailed information about the interface for the specified IPv6 address.

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.

Table 37 lists the show ipv6 address command output fields.

Table 37: show ipv6 address Output Fields

Field Name	Field Description

IPv6 statistics Sent	generated—Number of packets generated no routes—Number of packets that could not be routed discards—Number of packets that could not be routed that were discarded Note: If you configure the router to discard packets for static routes with null 0 interfaces as the next-hop points using the reject keyword with the ipv6 route command, the value displayed in this field also includes the packets that reached the null 0 interface and were dropped.
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 or 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
ICMPv6 statistics Sent	total—Total number of sent packets errors—Error packets sent destination unreach—Packets sent with destination unreachable Note: If you configure the router to discard packets for static routes with null 0 interfaces as the next-hop points using the reject keyword with the ipv6 route command, the value displayed in this field also includes the number of ICMPv6 unreachable messages sent out for packets that reached null 0 interfaces with static routes. admin unreach—Packets sent because the destination was administratively unreachable (for example, due to a firewall filter) parameter problem—Packets sent with parameter errors time exceeded—Packets sent 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—Sent packet redirects echo requests—Echo request (ping) packets echo replies—Echo replies sent 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 of which the interface is assigned

In Total Dropped Packets, Bytes	Total number of inbound packets and bytes dropped on this interface
In Policed Packets	Packets that were received and dropped on the interface for any of the following reasons: exceeding the token bucket limit, exceeding the rate limit, a drop action in a policy, discarded MAC validation packets, a destination address lookup failure, or when the destination address is an IP interface that has a route configured to the null 0 interface.
In Invalid Source Address Packets	Packets received with invalid source address (for example, spoofed packets)
In Error Packets	Number of packets received with errors
In Discarded Packets	Packets received that were discarded for reasons other than rate limits, errors, and invalid source address

Unicast Packets, Bytes	Unicast packets and bytes that were sent from this interface
Multicast Routed Packets, Bytes	Multicast packets and bytes that were sent from this interface

Out Scheduler Dropped Packets, Bytes	Number of outbound packets and bytes dropped by the scheduler
Out Policed Packets, Bytes	Number of outbound packets and bytes dropped because of rate limits
