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.
