If FIB TCAM exception is thrown for a transit route for IPv4 or IPv6 or MPLS traffic, the route does not get installed in FIB and connectivity gets affected. This limitation is applicable to DFC TCAM on XL line cards. FIB TCAM exception may be thrown in case of a route churn where TCAM utilization is more than 80% of the total utilization.Enter the show platform hardware pfc mode command to display the PFC mode.You must reboot to use a switching module equipped with a DFC that imposes a more restricted PFC mode than the current PFC mode.Switching modules that you install after bootup that are equipped with a DFC that imposes a more restricted PFC mode than the current PFC mode remain powered down.– PFC4XL and DFC4XL-No restrictions ( PFC4XL mode). – PFC4XL and DFC4-PFC4XL functionality is restricted by the DFC4: after a reload with a DFC4-equipped module installed, the PFC4XL functions as a PFC4 (PFC4 mode). PFC4XL-These restrictions apply to a configuration with a PFC4XL and these DFCs:.– PFC4 and DFC4XL-The PFC4 restricts DFC4XL functionality: the DFC4XL functions as a DFC4 (PFC4 mode). – PFC4 and DFC4-No restrictions (PFC4 mode). PFC4-These restrictions apply to a configuration with a PFC4 and these DFCs:.You must use identical policy feature cards for redundancy.
