After upgrading to 12.2(44)SE on a C3750 switch, we started getting the following new messages in the system log:
%PLATFORM_UCAST-6-PREFIX: One or more, more specific prefixes could not be programmed into TCAM and are being covered by a less specific prefix.
This is a warning only and this situation was already present before the upgrade (however, the message logging didn't exist). Now our log is full of these messages.
Can we supresses the messages ? And is it safe to do so ?
how many IP prefixes are in the routing table ?
It may be wise to reduce the number of IP prefixes learned by the device they are too many for the TCAM table size.
Or you may think to use the sdm prefer command to change the way the TCAM is used: another template may provide more space for IP prefixes (a reload is needed to be effective)
These two actions should stop these messages.
Hope to help
