CEF for PFC2 Configuration Guidelines and Restrictions

Follow these guidelines and restrictions when configuring CEF for PFC2:
•
•
•
CEF for PFC2 does not provide Layer 3 switching for an IP multicast flow in the following cases:
•
78-13315-02
PFC2 supports a maximum of 16 unique Hot Standby Router Protocol (HSRP) group numbers. You
can use the same HSRP group numbers in different VLANs. If you configure more than 16 HSRP
groups, this restriction prevents use of the VLAN number as the HSRP group number.
Identically numbered HSRP groups use the same virtual MAC address, which might
Note
cause errors if you configure bridging on the MSFC.
Because of the restriction to 16 unique HSRP group numbers, CEF for PFC2 cannot support the
standby use-bia HSRP command.
CEF for PFC2 supports the following ingress and egress encapsulations:
– For IP unicast:
Ethernet V2.0 (ARPA)
802.3 with 802.2 with 1 byte control (SAP1)
802.3 with 802.2 and SNAP
For IPX:
–
Ethernet V2.0 (ARPA)
802.3 (raw)
802.2 with 1 byte control (SAP1)
SNAP
Note When the ingress encapsulation for IPX traffic is SAP1, CEF for PFC2 provides Layer 3
switching only when the egress encapsulation is also SAP1. The MSFC2 routes IPX
SAP1 traffic that requires an encapsulation change.
For IP multicast—Ethernet V2.0 (ARPA)
–
For IP multicast groups that fall into the range 224.0.0.* (where * is in the range 0–255), which is
used by routing protocols. CEF for PFC2 supports 225.0.0.* through 239.0.0.* and 224.128.0.*
through 239.128.0.*.
