Policy Based Routing

Policy Based Routing (PBR) allows a network administrator to define QoS policies that override the
normal routing mechanism for traffic matching the policy condition.
Note. When a PBR QoS rule is applied to the configuration, it is applied to the entire switch, unless you
specify a built-in port group in the policy condition.
Policy Based Routing can be used to redirect traffic to a particular gateway based on source or destination
IP address, source or destination network group, source or destination TCP/UDP port, a service or service
group, IP protocol, or built-in source port group.
Traffic can be redirected to a particular gateway regardless of what routes are listed in the routing table.
Note that the gateway address does not have to be on a directly connected VLAN; the address can be on
any network that is learned by the switch.
Note. If the routing table has a default route of 0.0.0.0, traffic matching a PBR policy is redirected to the
route specified in the policy. For information about viewing the routing table, see
ing IP."
