Configuring Policy-Based Forwarding
This example shows how to clear the PBF MAC address:
Console> (enable) clear pbf
PBF cleared.
Console> (enable)
Console> (enable) show pbf
Pbf status
-----------
not set
Console> (enable)
Specifying the PBF MAC Address on a VLAN
This PBF configuration step is required only on the Supervisor Engine 720 with
Note
PFC3A/PFC3B/PFC3BXL.
The set pbf vlan vlan command creates the PBF Layer 2 CAM entries on the specified VLANs. The packets
that match these entries are classified as Layer 3 packets. The Layer 2 entries are created only if the PBF
MAC address is set using the set pbf mac command before using the set pbf vlan command.
To specify the PBF MAC address on a VLAN, perform this task in privileged mode:
Task
Specify the PBF MAC address on a VLAN.
This example shows how to specify the PBF MAC address on a VLAN:
Console> (enable) set pbf vlan 11-12
Console> (enable) PBF enabled on vlan(s) 11-12.
Operation successful.
Console> (enable) show pbf
Pbf status
-----------
ok
Console> (enable)
The message "Operation successful" indicates that the PBF MAC address was saved in NVRAM.
Entering the clear pbf command does not clear the VLANs that are enabled for PBF. The clear pbf command
clears the Layer 2 table entries that are associated with the VLANs (because the MAC address is no longer
valid). You must explicitly clear the PBF-enabled VLANs to remove them from NVRAM by entering the
clear pbf vlan vlan_list command.
Configuring VACLs for PBF
Enter the set security acl adjacency command to specify the rewrite information in the adjacency table
Note
that causes the packet header (the destination VLAN and source and destination MAC addresses) to be
rewritten and forwarded to the destination VLAN.
The source MAC address is optional. If you do not specify the source MAC address, the system defaults to
the PBF MAC address.
