OK, So let us assume it is an issue with FIB, is there any way to detect that this problem is imminent? Is there a way to track LC RAM utilization via SNMP or another way?
Maybe that would be a good first step. -Drew -----Original Message----- From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED] On Behalf Of Matt Addison Sent: Friday, August 10, 2007 12:20 PM To: [EMAIL PROTECTED]; [email protected] Subject: Re: [c-nsp] Quick question about redundant connections. The "stops routing" sounds like FIB issues causing CEF to turn off on the linecards. How much memory do you have on the linecards? ( "show diags | inc (SLOT|MEM-|Engine)" ). If you have less than 256M processor memory on any linecard you may want to look into taking it up to 256M. To check if this is indeed happening, the next time it happens try executing a "execute-on slot <slot> show cef state", if CEF is disabled, the LC may have run out of memory. ~Matt -----Original Message----- From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED] On Behalf Of Mark Tinka Sent: Friday, August 10, 2007 11:45 AM To: [email protected] Subject: Re: [c-nsp] Quick question about redundant connections.

Sounds like a probable candidate for BFD; but doesn't quite explain why your box "stops routing".
