Description
Display system-wide protocol-related statistics.
Options
The
following are all possible options for the show system
statistics command. The available options vary
depending on the platform, software release, and operating system
(Junos OS and Junos OS Evolved).
Use the show system statistics ? command to
determine the available options.
| none |
Display system statistics for all the following protocols:
|
| all-chassis | (TX Matrix and TX Matrix Plus routers only) (Optional) Display system statistics for a protocol for all the routers in the chassis. |
| all-lcc | (TX Matrix and TX Matrix Plus routers only) (Optional) On a TX Matrix router, display system statistics for a protocol for all T640 routers (or line-card chassis) connected to the TX Matrix router. On a TX Matrix Plus router, display system statistics for a protocol for all routers (line-card chassis) connected to the TX Matrix Plus router |
| all-members | (EX4200 switches and MX Series routers only) (Optional) Display system statistics for a protocol for all members of the Virtual Chassis configuration. |
| lcc number | (TX Matrix and TX Matrix Plus routers only) (Optional) On a TX Matrix router, display system statistics for a protocol for a specific T640 router that is connected to the TX Matrix router. On a TX Matrix Plus router, display system statistics for a protocol for a specific router that is connected to the TX Matrix Plus router. Replace number with the following values depending on the LCC configuration:
|
| local | (EX4200 switches and MX Series routers only) (Optional) Display system statistics for a protocol for the local Virtual Chassis member. |
| member member-id | (EX4200 switches and MX Series routers only) (Optional)
Display system statistics for a protocol for the specified member
of the Virtual Chassis configuration. For EX4200 switches, replace |
| scc | (TX Matrix routers only) (Optional) Display system statistics for a protocol for the TX Matrix router (or switch-card chassis). |
| sfc number | (TX Matrix Plus routers only) (Optional) Display system
statistics for a protocol for the TX Matrix Plus router (or switch-fabric
chassis). Replace |
Additional Information
By default, when you issue the show system statistics command on a TX Matrix or TX Matrix
Plus primary Routing Engine, the command is broadcast to all the T640
(in a routing matrix based on the TX Matrix router) or T1600 (in a
routing matrix based on the TX Matrix Plus router) primary Routing
Engines connected to it. Likewise, if you issue the same command on
the TX Matrix or TX Matrix Plus backup Routing Engine, the command
is broadcast to all the T640 (in a routing matrix based on the TX
Matrix router) or T1600 (in a routing matrix based on the TX Matrix
Plus router) backup Routing Engines that are connected to it.
