NOTE: The total bandwidth of all line modules must not exceed 5 Gbps. To make optimal use
of the available bandwidth, put line modules that require maximum bandwidth in slot 2, 3, or
4.

Specifying the Type of Performance
After you have installed a suitable combination of line modules, you can specify a
different type of performance. To specify the type of performance:
1. Issue the show bandwidth oversubscription command.
2. If the setting is not the one you want, enable or disable bandwidth
oversubscription.
