Policy Feature Card Guidelines and Restrictions

• The PFC3 supports a theoretical maximum of 64,000 MAC addresses (32,000 MAC addresses

recommended maximum).

• You cannot use one type of PFC3 (PFC3BXL or PFC3B) on one supervisor engine and a different

type on the other supervisor engine for redundancy. You must use identical policy feature cards for

redundancy.

• Enter the show platform hardware pfc mode command to display the PFC3 mode.

• Enter the show platform earl-mode command to display the PFC3 mode.

• PFC3B—These restrictions apply to a configuration with a PFC3B and these DFCs:

–

PFC3B and DFC3B—No restrictions.

–

PFC3B and DFC3BXL—The PFC3B restricts DFC3BXL functionality: after a reload with a

DFC3BXL-equipped module installed, the DFC3BXL functions as a DFC3B.

• PFC3BXL—These restrictions apply to a configuration with a PFC3BXL and these DFCs:

–

PFC3BXL and DFC3B—PFC3BXL functionality is restricted by the DFC3B: after a reload

with a DFC3B-equipped module installed (whether powered up or down), the PFC3BXL

functions as a PFC3B.

–

PFC3BXL and DFC3BXL—No restrictions.

• The features that require the PFC3BXL or PFC3B are not supported in PFC3A mode (see the

Release Notes for Cisco IOS Release 12.2SR on the Cisco 7600 Series Routers).

• To use DFC3B-equipped switching modules with a PFC3BXL, the DFC3B-equipped switching

modules must be installed at bootup.
