Brocade CER 2024C NP CSRAM error

[Daan]

Hello,

Who can tell me what the following error exactly means? I receive this since a couple of days every 10 minutes.

I know I can set the threshold higher then the default (10), but that looks my not the solution.

NP CSRAM has 12 error events, exceeding configured threshold for interfaces 2/1 to 2/2.

I have a Brocade 2024C router with a 2x10G module.

Regards,
Daan

Hello,

Thanks for the information about this message.
We have a replacement device and module so in case of a failure we can replace them.

At the moment we are still running on 5.4 so we also take a look for the upgrade.

Thanks again.

Regards,
Daan
