ACL deny entries can be logged to the syslog server.
Log timeout is the period the switch waits before sending
updates about any ACL deny matches to the syslog server.
The same log timer will be used for ipv4 and ipv6 logging.
The configurable value is from 30 to 300.Maximum limit is given
as 65535 so that if the value is increased in the future, the mib need
not be modified.
