Extended profiles
Passing or failing the SRS rule check is the only authorization control provided at 
the group level. This is the base profile. In future releases of the Nortel 
SNAS 4050 software, extended profiles will provide a mechanism to achieve 
more granular authorization control, based on specific characteristics of the user's 
connection. You can define up to 63 extended profiles for each group.
In Nortel Secure Network Access Switch Software Release 1.0, the data for an 
extended profile include the following configurable parameters:
linksets
the VLAN which the user is authorized to access 
Each extended profile references a client filter in a one-to-one relationship. With 
Nortel Secure Network Access Switch Software Release 1.0, you can configure 
the TunnelGuard check result as the criterion for the client filters, in order to 
establish the user’s security status.
The client filter referenced in the extended profile determines whether the 
extended profile data will be applied to the user. After the user has been 
authenticated and the TunnelGuard host integrity check has been conducted, the 
Nortel SNAS 4050 checks the group’s extended profiles in sequence, in order of 
the profile IDs, for a match between the client filter conditions and the user’s 
security status. When it finds a match, the Nortel SNAS 4050 applies that 
particular extended profile’s data to the user. Data defined for the base profile (for 
example, linksets) are appended to the extended profile’s data. If the Nortel 
SNAS 4050 finds no match in any of the extended profiles, it applies the base 
profile data.
