isis silent
Function
The isis silent command configures an IS-IS interface as a silent interface. That is, the interface is suppressed from sending and receiving IS-IS packets, but routes of the network segment on which the interface resides can be advertised.
The undo isis silent command restores the default setting.
By default, no IS-IS interface is configured as a silent interface.
Usage Guidelines
When an IS-IS network is connected to other ASs, it is required to enable IS-IS on the interfaces that connect the IS-IS network to other ASs so that the wireless access controller on the IS-IS network can learn the routes to other ASs. This interface, however, unnecessarily advertises IS-IS Hello packets on its network segment. In this case, you can run the isis silent command to suppress the IS-IS interface.
Prerequisites
IS-IS has been enabled on the interface using the isis enable command.
