Cisco 7604 logs

Hi,

 

We have found some logs (see attached) on our Cisco 7604, c7600rsp72043-advipservicesk9-mz.151-3.S5.bin. We thought that this could be the cause of customer complain.

 

Please if someone can explain the meaning of this log.

 

Jun 23 04:47:20.754 FJT: %MLSCEF-SP-4-FIB_EXCEPTION_THRESHOLD: Hardware CEF entry usage is at 95% capacity for IPv4 unicast protocol.

 

Appreciate your assistance in advance.

 

regards

Navi

We also had the same problem.

We also had the same problem.

Some of our clients had a problem with a packet loss to some resources and low connection speed.

Also we lose IPSec tunnels between the ASAs in our network.

I think this message is caused by TCAM memory exhaustion because of too large routing table. (We have 3 full views from the uplinks and some routes in vrf's.

What we did:

mls cef maximum-routes ip 716
mls cef maximum-routes ipv6 80

These commands will  increase your IPv4 capacity in TCAM and the message should go away.

Then you need to reboot the router.

These manipulations have helped us.
