[haibo li]

Hi,

I ask a question，I show logging in a switch ，In this switch, there are much more logging, I would like to filter these logging, such as the following ARP DAI logging ，Is there  a  way to deny DAI logging.

NO40-WAIWANG-HX#show logging
Syslog logging: enabled (0 messages dropped, 2 messages rate-limited, 0 flushes,
0 overruns)
    Console logging: level debugging, 226333 messages logged
    Monitor logging: level debugging, 0 messages logged
    Buffer logging: level debugging, 226334 messages logged
    Exception Logging: size (8192 bytes)
    Count and timestamp logging messages: disabled
    Trap logging: level informational, 226339 message lines logged

Log Buffer (2000000 bytes):

lan 3.([001b.7817.579a/10.224.0.87/0501.0201.0401/10.224.0.166/17:00:46 UTC Tue

Try this:

logging discriminator DAI mnemonics drop SW_DAI-4-DHCP_SNOOPING_DENY

logging buffered discriminator DAI 4096

logging monitor  discriminator DAI

logging console  discriminator DAI

Thank you very much！ but This is switch ！

Leo's method is the best. It uses the Embedded Syslog Manager feature present in more recent IOS versions.

Here is a comprehensive reference guide.
