Hi everyone,
please help sort out the problem.
I have the WS-C4500X-16 configured with BGP. Today, after an increase in provider prefixes from 22K to 62K I get the error:
%C4K_L3HWFORWARDING-4-TCAMFULL: FLC Tcam full, packets will be forwarded in software at reduced rate. Failure due to: add tcam space failed
Nov 5 11:27:25.720: %COMMON_FIB-3-HW_API: HW API failure for IPv4 CEF [0x20B1A94C]: Out of Tcam resource (fatal) (0 subsequent failures).
Nov 5 11:27:25.720: %COMMON_FIB-4-DISABLING: IPv4 CEF is being disabled due to a fatal error.
Nov 5 11:28:10.308: %FIB-2-FIBDOWN: CEF has been disabled due to a low memory condition. It can be re-enabled by configuring "ip cef [distributed]"
Nov 5 11:29:10.306: %FIB-2-FIBDOWN: CEF has been disabled due to a low memory condition. It can be re-enabled by configuring "ip cef [distributed]"
Nov 5 11:30:10.306: %FIB-2-FIBDOWN: CEF has been disabled due to a low memory condition. It can be re-enabled by configuring "ip cef [distributed]"
Please tell me how to increase the TCAM table to 4500X or tell me another solution to this problem.
Thank you.
