BAM Release 2.0 sends only MIR values. BAM Release 2.1 and Prizm Release 2.0
and 2.1 send VLAN and high-priority channel values as well.
For the case where the Configuration Source parameter in the AP is set to BAM, the
SM stores a value for the Dynamic Learning VLAN parameter that differs from its factory
default. When Prizm does not send VLAN values (because VLAN Enable is set to No in
Prizm), the SM
• uses this stored Disable value for Dynamic Learning.
• shows the following in the VLAN Configuration web page:
• either Enable or Disable as the value of the Dynamic Learning parameter.
• Allow Learning : No under Active Configuration.
For the case where the Configuration Source parameter in the AP is set to BAM+SM,
and Prizm does not send VLAN values, the SM
• uses the configured value in the SM for Dynamic Learning. If the SM is set to
factory defaults, then this value is Enable.
• shows under Active Configuration the result of the configured value in the SM.
For example, if the SM is set to factory defaults, then the VLAN Configuration
page shows Allow Learning : Yes.
This selection (BAM+SM) is not recommended where Prizm manages the VLAN feature
in SMs.

NOTE:
The PTP 400 and PTP 600 series bridges (previously known as 30/60 Mbps and
150/300 Mbps Backhauls) are described in their own dedicated user guides. See

If an ADMINISTRATOR-level password has been set in the BHM, you must log into the
module before you can configure its parameters. See Managing Module Access by
