[bng] mac address format change - mac not being used for Auth

Hi, 

 

My question is regarding the Radius AVpair client-mac-address that is sent to a Radius server as part of the authentication process and accounting. Let me clarify first that we are NOT using the mac-address as part of the username at all. The username is constructed using different attributes.

 

During authentication or accounting the BNG sends Radius a number of attributes, including:

 

RADIUS: Cisco AVpair [1] 35 client-mac-address=aaaa.bbbb.cccc

(that is an extract of an accounting request).

As you can see, the mac-address format uses "." as separator.

 

We would like to change that mac-address format to a ":" separator that makes the mac-address look like this, for example:

aa:aa:bb:bb:cc:cc

 

Is this supported?

 

We're aware of that format being available when customizing the username that BNG is going to send to Radius, but in our case we're not using the mac-address as part of the username at all.

So, can we customize the client-mac-address AVP that BNG sends as part any regular accounting request?

 

Thanks!
c.
