Hi I need to rewrite this attribute Cisco-AVPair = "acct-input-octets-ipv6=xxx" upon receiving it in the accounting request from my BRAS to my Radius Server so I can further process. I received this Cisco-AVPair = "acct-input-octets-ipv6=xxx" I have done this on the Radius Server /etc/freeradius/sites-available/default if( &Cisco-AVPair[*]=~/\(acct-input-octets-ipv6\)=\(\d+)/ ) { update request { &acct-input-octets-ipv6 := "%{2}" } } But I have this on my debug if ( &Cisco-AVPair[*]=~/\(acct-input-octets-ipv6\)=\(\d+)/ ) { (0) if ( &Cisco-AVPair[*]=~/\(acct-input-octets-ipv6\)=\(\d+)/ ) -> FALSE Not sure if I can read it correctly but seem the rule does not matched .. Appreciate anyone comments if didn't do it correctly Confidentiality Notice: This email (including any attachment) is intended for internal use only.
