set pbf gw
set pbf gw
To add a PBF gateway to handle connections between VLANs, use the set pbf gw command.
set pbf gw gw_name ip_addr ip_mask mac_addr vlan
Syntax Description
Defaults This command has no default settings.
Command Types Switch command.
Command Modes Privileged.
Usage Guidelines Use this command with the set pbf gw command and the set pbf-map command to simplify the process
of setting and committing the security ACLs and adjacency information. The set pbf-map command
creates the security ACLs and adjacency information based on your input, commits them to the
hardware, and maps them to VLANs. As part of creating the nece ssary VACLs to redirect traffic from
one VLAN to another, the ARP packets are redirected to the software, and the supervisor engine
generates ARP replies for the gateway and client requests.
PBF clients and PBF gateways must be on different VLANs. No clients or gateways can have the same
IP address. The maximum number of entries is 1024.
The client name and gateway name must be no more than 12 characters.
If you create a PBF map between two VLANs that already have VACLs attached, the PBF ACLs
overwrite the previous configuration. The opposite is also tr ue. If you map a new VA CL to VL ANs w ith
PBF ACLs that were created by using the set pbf-map command, the new VACL overwrites the prev ious
configuration.
Note The number of PBF-client groups that can be mapped to a single PBF gateway is dependent on the
number of ACLs that are already configured. For example, if the number of supported ACLs is 250 and
you already have 20 ACLs defined, you can have 229 client groups mapped to a gateway.
For more information about using the set pfb client, set pbf gw, and set pbf-map commands, refer to
the “Configuring Policy-Based Forwarding” section of Chapter 16, “Configuring Access Co ntrol,” in the
Catalyst 6500 Series Software Configuration Guide.
