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).
Note:
Use the show system statistics ? command to
determine the available options.
| none |
Display system statistics for all the following protocols:
|
| all-members |
(EX4200 switches and MX Series routers only) (Optional) Display system statistics for a protocol for all members of the Virtual Chassis 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,
