VLAN membership update remains in effect while the related PBA policy is

active. Uplink ports must be operating in hybrid switch port mode to be valid.

Uplinks are identified using the interface type and the slot/port naming

convention (e.g., ‘Gi0/5, Ex0/1’). An action that includes uplink data must also

include VLAN data for port membership updates.

The PoE priority setting (i.e., Critical/High/Low) for a port can be updated

based on device discovery. The PoE priority setting is restored to the previous

statically configured value during the device cleanup phase.

Automatic interface description updates can (optionally) be initiated when a

PBA policy is applied to a port. The user may select the information used to

update the port description.

Limitations

Administrator can no longer alter most settings that have been updated by

PBA. Administrator operations on ports that are associated with an active

PBA policy are limited to those not potentially under PBA control. This means

that VLAN membership updates are blocked as are PVID and switch port

mode modifications. Furthermore, VLANs that are dynamically created

though PBA operations are owned by PBA and cannot be manipulated (e.g.,

deleted, associated with other ports) by the user. Administrator modifications

to these settings are permitted once PBA settings are cleared from the port.

Release 3.0.1

Device Identification

Deletion of active PBA policies is supported. Previously, a referenced (active) policy

could only be deleted when it was no longer applied to a port. This potentially

required the user to take the port down, disable PBA on the port or disable PBA for

the switch overall. The requirement has been eliminated.

Dynamic policy reordering based on PBA policy precedence is available. This

configurable option (enabled/disabled) allows PBA policies with higher precedence

to replace currently active PBA policies with lower evaluation precedence when both

are applicable to the discovered device. Active policy reordering is enabled by

default.

MAC address matching support can be customized for the environment to prevent

matching devices that are not directly connected. cnMatrix Release 2.1.0 MAC

address-based policy matching will match MAC addresses that are not directly

connected. In a bridged network with address flooding, this can result in PBA policies

being applied on potentially unexpected ports. The updated support allows the user

to select whether the current PBA MAC address-based policy operation is suitable

for their environment or if restricted MAC matching (targeting MACs of directly

connected devices only) is required.

A user configurable PBA setting is defined to control whether restricted MAC

matching is enabled or disabled (restricted MAC matching is enabled by

default).

New rules are enforced when evaluating whether PBA MAC-based policies

should be applied based on FDB events (enforced when restricted MAC

matching is enabled):

1. Do not apply MAC-based policies on switchport mode 'trunks'.

2. Ports with only one learnt MAC address are permitted to have policies

that match the MAC data be applied.

3. Ports with more than one learnt MAC are only allowed to have a policy

applied that matches the MAC address data that is the source MAC of
