mirrored (copied and transmitted) to port 12. This mirroring would be in addition to any Layer 3 or Layer 2 switching.

zmirror zre0 zre12 zmirror zre1 zre12 zmirror zre2 zre12

To clear the current mirroring use the -toption. The -eoption can be used to indicate that packets being sent on a given port should be copied to the mirror_to port. For example if the -eoption is used as follows, the packets transmitted, as opposed to received, on ports 0, 1 or 2 would be mirrored to port 12.

zmirror -e zre0 zre12 zmirror -e zre1 zre12 zmirror -e zre2 zre12

Link and LED Control

zlc zre1 down

To check the status of a link,

zlc zre1 query

To check the status of all links,

Link Event Monitoring

The zlmd application is intended to run as a daemon, waiting for a configured event to occur and then running the program configured for that event. The events monitored are changes in the link status at any of the in-band ports of the switch, the start of removal of the switch from the ATCA backplane, or the cancellation of the removal before it actually takes place. The program can be a shell script that initiates appropriate actions to respond to the event.
