Configuring PBR with other Features
Unsupported Features
© Copyright Lenovo 2016
Consider the following PBR behavior when configured with the features given
below:
DSCP: PBR ACLs can be used to remark an IP packet with a new
precedence/DSCP value. PBR ACL remark statements have higher priority than
the DSCP remark commands configured on ports.
Virtual Router Redundancy Protocol (VRRP): If PBR is enabled on a VRRP IP
interface, the PBR becomes effective on the interface when the switch becomes
the VRRP master on that IP interface.
Virtual Link Aggregation Group (VLAG): When configuring PBR on VLAG
ports, you must configure the same PBR policy on both the VLAG peers. You
cannot configure the next hop to be on a remote switch or on the VLAG ports.
PBR cannot be configured for:
Routed ports
Multicast traffic
IPv6 packets
Simple Network Management Protocol (SNMP)
Stacking
Virtual Network Interface Card (vNIC)
Loopback Interface
