Adding CLEAR-Flow Rules to ACLs
ExtremeWare XOS 11.3 Concepts Guide
385
For example (enabling mirroring from within CLEAR-Flow rule):
cli “enable mirroring to port 7:4 tagged”
mirror add acl_rule_1
SNMP Trap
This action sends an SNMP trap message to the trap server, with a configurable ID and message string,
when the rule is triggered.
The message is sent periodically with interval
<period>
seconds. If <period>
is zero, or if this optional parameter is not present, the message is sent only once when the rule is triggered. The interval must be
a multiple of the rule sampling/evaluation interval, or the value will be rounded down to a multiple of
the rule sampling/evaluation interval.
To send an SNMP trap, use the following syntax:
snmptrap <id> <message> <period>
Syslog
This action sends log messages to the ExtremeWare XOS EMS sever. The possible values for message
level are: DEBU, INFO, NOTI, WARN, ERRO, and CRIT.
The message is sent periodically with interval
<period>
seconds. If <period>
is zero, or if this optional parameter is not present, the message is sent only once when the rule is triggered. The interval must be
a multiple of the rule sampling/evaluation interval, or the value will be rounded down to a multiple of
the rule sampling/evaluation interval.
The messages are logged on both MSMs, so if the backup log is sent to the primary MSM, then the
primary MSM will have duplicate log messages.
To send a log message, use the following syntax:
syslog <message> <level> <period>
CLI
This action executes a CLI command. There is no authentication or checking the validity of each
command. If a command fails, the CLI will log a message in the EMS log.
To execute a CLI command, use the following syntax:
cli <cliCommand>
where <cliCommand> is a quoted string.
Keyword Substitution
To make the SNMP trap, syslog, and CLI actions more flexible, keyword substitutions are supported in
the syslog and SNMP trap message strings, as well as in the CLI command strings. Table 55 lists the
keywords and their substitutions.
