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-modecommand 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.
