Configuring 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 an expiry time for a particular entry.
If you configure both, the ACL supersedes the global configuration for the specified entries.
When you create, delete, or update an expiry time, the changes are applied when the keep alive timer
refreshes.
