Is there any way to block the duplex mismatch errors from CDP from being logged? I have a cisco switch which connects to a non-cisco switch which then connects to a number of devices including a Cisco ATA that does not support full duplex. On the cisco switch the port is autonegotiating to 100/Full, and so is the non-cisco.

When the ATA sends out its CDP packets it tells the cisco switch that it is using 10/half. The cisco switch enterprets that as being an error and logs it as:

%CDP-4-DUPLEX_MISMATCH: duplex mismatch discovered on FastEthernet0/6 (not half duplex), with SEP... Port 1 (half duplex).

It would be handy if I could prevent these from getting logged (or at least rate limit them)

Thanks in advance,

Peter
