I have an issue with a cisco 877 router that has a bug where every time it receives a dns request that needs to do dns forwarding it produces the following syslog message:
%FIB-4-FIBCBLK: Missing cef table for tableid 65535 during CEF samecable event
is there any way to filter just that message from overflowing my syslog server?
I have experimented with logging discriminator but wasn't able to figure out exactly how to do it.
This is what I've tried
#logging discriminator BUG mnemonics drops FIBCBLK
however when I do show logging I see this:
No Active Message Discriminator.
Inactive Message Discriminator:
BUG mnemonics drops FIBCBLK
