show system statistics icmp
Syntax
Syntax (EX Series Switches)
Syntax (TX Matrix Router)
Syntax (TX Matrix Plus Router)
Release Information
Command introduced before Junos OS Release 7.4.
Command introduced in Junos OS Release 9.0 for EX Series switches.
sfc option introduced for the TX Matrix Plus router in Junos OS Release 9.6.
Description
Display system-wide Internet Control Message Protocol (ICMP) statistics.
Options
none | — | Display system statistics for ICMP. |
all-chassis | — | (TX Matrix and TX Matrix Plus routers only) (Optional) Display system statistics for ICMP 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 ICMP for all T640 routers (or line-card chassis) connected to the TX Matrix router. On a TX Matrix Plus router, display system statistics for ICMP for all T1600 routers (or line-card chassis) connected to the TX Matrix Plus router. |
all-members | — | (EX4200 switches only) (Optional) Display ICMP statistics 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 ICMP for a specific T640 router that is connected to the TX Matrix router. On a TX Matrix Plus router, display system statistics for ICMP for a specific T1600 router that is connected to the TX Matrix Plus router. Replace number with a value from 0 through 3. |
local | — | (EX4200 switches only) (Optional) Display ICMP statistics for the local Virtual Chassis member. |
member member-id | — | (EX4200 switches only) (Optional) Display ICMP statistics for the specified member of the Virtual Chassis configuration. Replace member-id with a value from 0 through 9. |
scc | — | (TX Matrix routers only) (Optional) Display system statistics for ICMP for the TX Matrix router (or switch-card chassis). |
sfc number | — | (TX Matrix Plus routers only) (Optional) Display system statistics for ICMP for the TX Matrix Plus router (or switch-fabric chassis). Replace number with 0. |
Additional Information
By default, when you issue the show system statistics icmp command on a TX Matrix or TX Matrix Plus master 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) master 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.
