Disabling UDP Checksum Processing on an Interface
By default, all outgoing and incoming UDP datagrams are subject to checksum
processing. You can use the BCC or Site Manager to disable or reenable UDP
checksum processing as required. Use the default in virtually all instances.
Disable UDP checksum processing to provide backward compatibility with UNIX
BSD 4.1.
Using the BCC
To disable or reenable UDP checksum processing, go to an IP interface prompt
(for example,
box; eth 2/2; ip/2.2.2.2/255.255.0.0
) and enter:
udp-checksum
<state>
state
is one of the following:
enabled
(default)
disabled
For example, the following command turns off UDP checksum processing on IP
interface 2.2.2.2:
ip/2.2.2.2/255.255.0.0#
udp-checksum disabled
ip/2.2.2.2/255.255.0.0#
