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 routers and TX Matrix Plus routers only) (Optional) Display system statistics for ICMP for all the routers in the chassis. |
all-lcc | — | (TX Matrix routers 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 connected T1600 or T4000 LCCs. |
all-members | — | (EX4200 switches only) (Optional) Display ICMP statistics for all members of the Virtual Chassis configuration. |
lcc number | — | (TX Matrix routers 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 router that is connected to the TX Matrix Plus router. Replace number with the following values depending on the LCC configuration:
|
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 and TX Matrix Plus routers with 3D SIBsonly) (Optional) Display system statistics for ICMP for the TX Matrix Plus router. Replace number with 0. |
Additional Information
By default, when you issue the show system statistics icmp command on the master Routing Engine of a TX Matrix router or a TX Matrix Plus router, the command is broadcast to all the master 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.
