Monitoring the Policy Configuration of IPv6 Interfaces

Purpose

Display detailed or summary information, including policy and classifier information, for a particular IPv6 interface or for all interfaces. The default for the show ipv6 interface command is all interface types and all interfaces. The brief or detail keywords with the show ipv6 interface command displays different levels of information.

Action

To display information about IPv6 policy lists:

Table 33 lists the show
ipv6 interface command output fields.



Table 33:   show ipv6
interface Output Fields   












Field Name



Field Description










Description



Optional description for the interface or address specified








Network Protocols



Network protocols configured on this interface








Link local address



Local IPv6 address of this interface








Internet address



External address of this interface








Operational MTU



Value of the MTU








Administrative MTU



Value of the MTU if it has been administratively overridden
using the configuration








Operational speed



Speed of the interface








Administrative speed



Value of the speed if it has been administratively overridden
using the configuration








Creation type



Method by which the interface was created (static or
dynamic)








ND reachable time



Amount of time (in milliseconds) that the neighbor is
expected to remain reachable








ND duplicate address detection attempts



Number of times that the router attempts to determine
a duplicate address








ND neighbor solicitation retransmission interval



Amount of time (in milliseconds) during which the router
retransmits neighbor solicitations








ND proxy



Whether the router replies to solicitations on behalf
of a known neighbor, enabled or disabled








ND RA source link layer



Whether the RA includes the link layer








ND RA interval



Amount of time (in seconds) of the neighbor discovery
router advertisement 








ND RA lifetime



Amount of time (in seconds) of the neighbor discovery
router advertisement








ND RA managed flag



State of the neighbor discovery router advertisement
managed flag, enabled or disabled








ND RA other config flag



State of the neighbor discovery router advertisement
other config flag, enabled or disabled

Whether advertisement prefixes for neighbor discovery
router advertisement are configured








In Received Packets, Bytes

frames) are counted as unicast packets








Multicast Packets, Bytes



Number of multicast packets and bytes received on the
IPv6 interface, which are then multicast-routed and counted as multicast
packets

classifier-group entry



Entry index








Committed



Number of packets and bytes that conform to the committed
access rate
