Hi Everyone,

I am seeing log messages below

%ASA-7-710005: UDP request discarded from 192.168.10.12/137 to video:192.168.10.255/137

Lot of messages are showing up.

Need to understand what does this message mean?

Hi Mahesh,

This is just NETBIOS traffic that is being dropped by the ASA.

Hi Mahesh,

You need to determine why the NetBIOS traffic is being sent to the ASA and stop it.

ASA will not allow the broadcast traffic to pass through it.

Hi Mahesh,

The ports in the syslog do not refer to video traffic, it's NETBIOS traffic and you need to find why the broadcast is directed through the ASA.
