To change the hit sample rate
The hit sample rate specifies the time interval, in seconds, at which the
packet counter is sampled for each security ACE on which the hit counter
is enabled.
By default, the hit sample rate is 0, even when the hit counter is enabled.
To use the hit counter, you must enable it
and set the hit sample rate. The
hit sample rate applies globally to all ACEs on which the hit counter is
enabled.
1 In the Task List panel, select Edit ACL hit sample rate.
2 Select or type the number of seconds between updates in the Hit Sample
Rate box.
3 Click OK .
To enable the hit counter for an ACE
You can enable the hit counter on an individual ACE basis.
1 Select the ACE in the ACL table.
2 In the Task List panel, select Enable Hits for this rule .
You also must set the hit sample rate to a value greater than 0, which is
the default. (See “To change the hit sample rate”.)
To enable the established option for TCP ACEs
By default, a new TCP ACE applies to new sessions as well as established
(existing) sessions. To apply the ACE only to established sessions, enable
the established option.
1 Select the TCP ACE in the ACL table.
2 In the Task List panel, select Enable Established Connections .
To specify the type and code for ICMP ACEs
1 Select the ICMP ACE in the ACL table.
