CSS11503 - lost of service

[feliperodero]

We have 2 CSS11503, one as Master and other as Backup. We've had problems because one service has been down and only after reboot both devices we have recovered the service.

Any idea how to identify cause of this problem ?

Today we had same problem and we need to reboot again boot CCS.

In log only these messages:

Rebooting a device to solve a problem is good.

Rebooting a device to then wonder what was the issue is bad :-(

Some troubleshooting would have been useful.

Could you ping the service at the time of the problem ?

What kind of keepalive ? TCP ? HTTP ?

What CSS software version ?

How is the server connected to the CSS ? directly or switch ?

Did you verify L2 ?

Did you capture a sniffer trace to see if the CSS were sending keepalive ?

Thanks,

Gilles.
