5.1.2 List of attributes that can be declared comparable.

The following attributes can be declared as comparable:

• User-Name
• Password
• CHAP-Password
• NAS-Port-Id
• State
• Called-Station-Id
• Calling-Station-Id
• NAS-Identifier
• Acct-Status-Type
• Acct-Session-Id

Notice that this list is by no means an exhaustive one. Depending on a particular NAS other attributes may be safe to be used in comparisons, or, vice-versa, some attributes from this list may not be used. You should carefully analyze packets coming from your NAS before deciding which attributes to mark as comparable.
