Table 13: Variable definitions
Variable Value
WORD<4-4> Adds a forced message control pattern, where WORD<4-4>
is a string of 4 characters. You can add a four-byte pattern
into the force-msg table. The software and the hardware log
messages that use the first four bytes that match one of the
patterns in the force-msg table undergo the configured
message control action. You can specify up to 32 different
patterns in the force-msg table, including a wildcard pattern
(****) as well. If you specify the wildcard pattern, all messages
undergo message control.
