Command Modes Global configuration

Command History

Usage Guidelines A retransmitted RADIUS Stop might cause the CSG2 to remove a subscriber entry from the CSG2 User

Table when the entry should not be removed.

To avoid this problem, the CSG2 must be able to associate a session correlator from the RADIUS Start

message with a subscriber entry in the User Table, and compare that correlator with the correlator in the

RADIUS Stop message. If the correlators match, the CSG2 deletes the subscriber entry; otherwise, the

CSG2 retains the entry in the User Table.

The CSG2 can use the Acct-Session-Id (attribute 44) as the correlator, or it can use the following

vendor-specific attribute (VSA) subattribute (attribute 26, Vendor-Id 9, subattribute 1):

csg:user_session_correlator=<string>

If both attributes are included in the RADIUS Start or RADIUS Stop message, the CSG2 uses the VSA

subattribute.

To enable this capability, enter the ip csg radius correlation command.

• If there is no correlator saved in the User Table entry, the CSG2 deletes the entry.

• If there is a correlator saved in the User Table entry, the CSG2 compares it to the correlator in the

RADIUS Stop. If the correlators match, the CSG2 deletes the entry; if they do not match, or if there

is no correlator in the RADIUS Stop, the CSG2 retains the entry in the User Table.

To disable this capability, enter the no ip csg radius correlation command. The CSG2 deletes User

Table entries without subscriber session correlation.

Examples The following example shows how to enable RADIUS correlation processing by the CSG2.

ip csg radius correlation
