Bandwidth Limitations of Shared Tunnel-Server Ports

Bandwidth limitations for shared tunnel-server ports and tunnel-service interfaces
depend on bandwidth restrictions, if any, that are in effect for the module on which
the shared tunnel-server port resides.

Exchanging Tunnel-Server Modules

Tunnel-server modules are available in different hardware revisions that support
varying numbers of tunnel-service interfaces. For more information about determining
the hardware revision on a module, see ERX Module Guide, Table 1, Module
Combinations, or E120 and E320 Module Guide, Table 1, Modules and IOAs.
When you exchange a tunnel-server module with a lower capacity for tunnel-service
interfaces with a module that supports a higher capacity, the tunnel-server port
maintains the original number of provisioned tunnel-service interfaces. By using the
all-available keyword with the max-interfaces command, you can configure the
tunnel-server port to automatically adjust the number of provisioned tunnel-service
interfaces to the maximum value supported by the new module.
When you exchange a tunnel-server module that has a higher number of provisioned
interfaces than the new module's capacity, the module adjusts the provisioned
number of interfaces to the maximum value that the module supports.
Table 23 on page 220 displays sample capacity, configuration, and utilization values
for exchanging tunnel-server modules with different capacities.

Interfaces

Unprovisioned Tunnel-Service Interfaces

Tunnel-server ports exist whether or not they have been configured. This means that
you cannot delete a tunnel-server port from a module. However, you can unprovision
