css11503 switchover

[xuan.z]

two css11503 with box-to-box redundancy,they swithovered there times,what reasons should cause box-to-box swithover?

[Gilles Dufour]

could you send a 'sho redundancy'.

Some of the possible reasons :

- critical service went down

- faulty cable on the redundancy link

- CSS redundancy link going through a switch [not supported config] and the switch had a problem

- human manipulation error

show redundancy and log file should give you the reason.

Regards,

Gilles

what about the other side ?

Did you capture the same info ?

If nothing there, check the log file.
