Advanced Traffic Management Guide K/KA/KB.15.15

the next action is tried, and so on, until an interface null or the end of the list of configured
actions is encountered. If the end of the list is reached, the policy action for that class behaves
as if no PBR policy is applied.
• The maximum combined number of unique IP next-hops and default-next-hops supported is
256.
Example 222 TCP and UDP traffic routing
The following example shows TCP and UDP traffic routed on different network paths. First, the
traffic classes are created, then the PBR policy is created, and lastly the PBR policy is applied to
an interface.
HP Switch(config)#: class ipv4 TCP
HP Switch(config-class)#: match tcp 10.0.8.1/24 15.29.16.104/24 eq 80

Troubleshooting PBR
Use the show statistics policy command to display information about which PBR action
for an applied policy is active. Hit counts for each entry in the class and policy with the active
action are displayed.
HP Switch(vlan-111)#: show statistics policy TCP_UDP vlan 111 in
