L2 Features 142

Device Identification

PBA Rule modification is now supported. Rules that are referenced by an active PBA

policy cause the policy to be reapplied (if still applicable) following the rule

modification.

The LLDP-ANY rule type is enhanced to check all (PBA-supported) string-based

LLDP TLVs for the target device identification data.

Policy Support

PBA Policy modification has been enhanced to allow the associated rule and/or

action criteria to be updated without redefining the policy. Active policies are

reapplied following modification, assuming they are still applicable.

PBA policy configuration allows the user to identify specific ports on which the

policy can be applied. The effectively introduces a two-stage policy match: the

associated rule criteria is first evaluated against the target device identification data.

If a match is found, the policy port list is consulted to see if the device identification

data was received through a port in the port list. If the port list is not empty, a port

match is required for the policy to be applied. A port list is empty by default (i.e., with

an empty port list policy behavior is the same as if previous releases).

Release 4.5

Action Localization

PBA action localization allows the same PBA policies to apply different settings

based on certain device characteristics (a.k.a. device localization). This simplifies

policy definition (no need for multiple policies with different actions) and allows

action criteria to be changed by updating the device localization data. Localization

allows the user to design network-wide (represented by a cnMaestro switch group)

PBA policies that can have their associated action settings (i.e., the action context)

easily customized for specific devices as needed.

MAC List Support

PBA MAC list support allows PBA rules to be enhanced to support a non-contiguous

range of MAC addresses for device identification. A user can download files that

contain a list of MAC addresses. These named MAC lists can then be associated with

rules using a new ‘MAC list’ rule type. When such a rule is associated with a PBA

policy, the list of MAC addresses is consulted when determining if the policy matches

the device identification data (i.e., a MAC address in this scenario) during the policy

evaluation process.

General Limitations

Interactions with authentication (802.1x) support are not supported.

PBA policies are not applicable to port channels.

Traffic associated with the native VLAN egresses the switch as untagged traffic (i.e., the

port is made an untagged member of the VLAN).
