Configurable S,G Expiry Timers
By default S, G entries expire in 210 seconds. You can configure a global expiry time (for all (S,G) entries)
or configure a expiry time for a particular entry. If both are configured, the ACL supercedes the global
configuration for the specified entries.
When an expiry time created, deleted, or updated, the changes are applied when the keep alive timer
refreshes.
To configure a global expiry time:
Task Command Command Mode
Enable global expiry timer for S, G entries
Range 211-86400 seconds
