Command introduced before Junos OS Release 7.4.
Command introduced in Junos OS Release 9.0 for EX Series switches.
sfc option for the TX Matrix Plus router introduced in Junos OS Release 9.6.
Command introduced in Junos OS Release 11.1 for the QFX Series.
Display information about the conditions that have been configured to trigger alarms.
none | — | Display information about the conditions that have been configured to trigger alarms. |
all-members | — | (MX Series routers only) (Optional) Display information about alarm conditions for all the member routers of the Virtual Chassis configuration. |
interconnect-device name | — | (QFabric switches only) (Optional) Display information about alarm conditions for the Interconnect device. |
lcc number | — | (TX Matrix and TX Matrix Plus routers only) (Optional) On the TX Matrix router, show information about a specified T640 router (or line-card chassis) that is connected to the TX Matrix router. On the TX Matrix Plus router, show information about a specified T1600 router (or line-card chassis) that is connected to the TX Matrix Plus router. Replace number with a value from 0 through 3. |
local | — | (MX Series routers only) (Optional) Display information about alarm conditions for the local Virtual Chassis member. |
member member-id | — | (MX Series routers only) (Optional) Display information about alarm conditions for the specified member of the Virtual Chassis configuration. Replace member-id with a value of 0 or 1. |
node-device name | — | (QFabric switches only) (Optional) Display information about alarm conditions for the Node device. |
scc | — | (TX Matrix router only) (Optional) Show information about the TX Matrix router (or switch-card chassis). |
sfc number | — | (TX Matrix Plus router only) (Optional) Show information about the TX Matrix Plus router (or switch-fabric chassis). Replace number with 0. |
You cannot clear the alarms for chassis components. Instead, you must remedy the cause of the alarm. When a chassis alarm is lit, it indicates that you are running the router or switch in a manner that we do not recommend.
On routers, you can manually silence external devices connected to the alarm relay contacts by pressing the alarm cutoff button, located on the craft interface. Silencing the device does not remove the alarm messages from the display (if present on the router) or extinguish the alarm LEDs. In addition, new alarms that occur after you silence an external device reactivate the external device.
In Junos OS release 11.1 and later, alarms for fans also show the slot number of the fans in the CLI output.
In Junos OS Release 11.2 and later, the command output on EX8200 switches shows the detailed location (Plane/FPC/PFE) for link errors in the chassis.
In Junos OS Release 10.2 and later, an alarm is shown on T Series routers for a standby sonic clock generator (SCG) that is offline or absent.
