Cable Data Gateways
Manage the Port Triggering Time-Out Period
By default, port triggering is enabled with a time-out period of 10 minutes.
The time-out value controls the inactivity timer for the designated inbound ports. The inbound
ports close when the inactivity time expires. This closure is required because the cable data
gateway cannot detect when the application terminates.
If you disable port triggering after you configured port triggering services, the services are
retained even though they are not used.
To change the port triggering time-out period:
1.
On your computer, launch an Internet browser such as Mozilla Firefox or Microsoft
Internet Explorer.
2.
In the address field of your browser, enter
http://routerlogin.net
.
You are prompted to enter a user name and password.
