EEM for SyncE QL

Hi

Is there a way to make a EEM script to shutdown E1 interface when SyncE QL goes under SSU-A?
I don't what to match sh log output

Please provide the step-by-step instructions on how you would do this manually.  If it can be done manually through SNMP or CLI, then it should be doable with EEM.

Hi
Thank you for your replay, this would really help me

1. If a QL announcement arrives from the network, like "%NETCLK-6-QL_CHANGE:" or if the router looses the communication to all clocks in the network and starts to use the internal clock "%NETCLK-6-ENTER_HOLDOVER:" then...

2. Wait for about 5 minutes.

3. Then If the output from "show network-clocks synchronization" shows either QL-PRC or QL-SSU-A, then bring up 8 interfaces. But if the output show neither of QL-PRC or SSU-A then shutdown 8 interfaces and save configuration.

4. Run step 3 every 30 minutes

This is not enough information.  What does the output of "show network-clocks synchronization" look like when it's healthy?  When it's not?  On what platform is this?  What version of software?

Hi
This is the output, it's a ASR 920 IOS XE 3.18.1s

In this output I have QL-PRC from both interfaces.
If the show command doesn't show either QL-PRC or QL-SSU-A anyware in the output, then shutdown 8 interfaces (controller e1 0/1/0 - 8)

And this is the output when the eem/tcl should shutdown the interfaces, in the output both PRC and SSU-A is missing

I think this will work for you.
