Description

Display system-wide Internet Control Message Protocol for IPv6 (ICMPv6) statistics.

Options

none

Display system statistics for ICMPv6.

all-chassis

(Optional) Display system statistics for ICMPv6 for all the routers in the chassis.

all-lcc

(Optional) On a TX Matrix router, display system statistics for ICMPv6 for all T640 routers connected to the TX Matrix router. On a TX Matrix Plus router, display system statistics for ICMPv6 for all connected T1600 or T4000 LCCs.

all-members

(Optional) Display ICMPv6 statistics for all members of the Virtual Chassis configuration.

lcc number

(Optional) On a TX Matrix router, display system statistics for ICMPv6 for a specific T640 router that is connected to the TX Matrix router. On a TX Matrix Plus router, display system statistics for ICMPv6 for a specific router that is connected to the TX Matrix Plus router.

Replace number with the following values depending on the LCC configuration:

  • 0 through 3, when T640 routers are connected to a TX Matrix router in a routing matrix.

  • 0 through 3, when T1600 routers are connected to a TX Matrix Plus router in a routing matrix.

  • 0 through 7, when T1600 routers are connected to a TX Matrix Plus router with 3D SIBs in a routing matrix.

  • 0, 2, 4, or 6, when T4000 routers are connected to a TX Matrix Plus router with 3D SIBs in a routing matrix.

local

(Optional) Display ICMPv6 statistics for the local Virtual Chassis member.

member member-id

(Optional) Display ICMPv6 statistics for the specified member of the Virtual Chassis configuration. Replace member-id with a value from 0 through 9.

scc

(Optional) Display system statistics for ICMPv6 for the TX Matrix router (or switch-card chassis).

sfc number

(Optional) Display system statistics for ICMPv6 for the TX Matrix Plus router. Replace number with 0.

Additional Information

By default, when you issue the show system statistics icmp6 command on the primary Routing Engine of a TX Matrix router or a TX Matrix Plus router, the command is broadcast to all the primary Routing Engines of the LCCs connected to it in the routing matrix. Likewise, if you issue the same command on the backup Routing Engine of a TX Matrix or a TX Matrix Plus router, the command is broadcast to all backup Routing Engines of the LCCs that are connected to it in the routing matrix.
