What happens if I disable the FCP?
The FCP is an optional feature that is available for the supported CBX 500 IOM listed
above. See “Enabling the FCP” on page 6-2 for instructions on enabling and disabling
the FCP.
When you disable the FCP, all of the IOM and logical port attributes related to the
FCP are reset to their default values. The only exception is the RM Cell Generation
Type, which remains configured whether or not an FCP is present.
If you disable the FCP, the IOM is unable to:
• Perform intelligent discarding on a per-connection basis.
• Provide minimum rate guarantees on a per-connection basis.
• Minimize latency in the event of network congestion.
