Shared tunnel-server ports are virtual ports that are always present on certain E-series line modules that provide tunnel services in addition to regular access services. You can configure the shared tunnel-server port to use a portion of the module’s bandwidth to provide tunnel services.
Shared tunnel-server ports offer the following benefits:
You can use a shared tunnel-server module to provide tunnel services as an alternative to using a dedicated tunnel-server module.
If you have limited tunnel-server processing needs, you can provide tunnel services on a single available port of a shared tunnel-server module instead of having to allocate the entire bandwidth of a dedicated tunnel-server module for this purpose.
