iRule not working to have a RADIUS presistant load balancing.

Hi ZANOOB,

[RADIUS::avp 31 string] may be returning empty string. If empty, iRule will throw an error.

Can you investigate the ltm logs and try this iRule?

when CLIENT_DATA {
	if { [UDP::local_port] == 1813 } {
		set CALLID [RADIUS::avp 31 string]
		set IP [RADIUS::avp 8 ip4]
		if { $IP != "" } {
			table set $IP [LB::server addr] 900
			log local0. "Radius maps $IP to [LB::server addr] for $CALLID"
		}
	}
}
 
when CLIENT_ACCEPTED {
	if { ([UDP::local_port] != 1812) && ([UDP::local_port] != 1813) } {
		log local0. "packet on port [UDP::local_port] dropped"
		drop
	}
	elseif {
		set CALLID [RADIUS::avp 31 string]
		log local0. "persisted $CALLID"
		
		if { $CALLID ne "" } {
			persist uie $CALLID
		}
	}
}
 
when CLIENT_DATA {
	if { [UDP::local_port] == 1813 } {
		set CALLID [RADIUS::avp 31 string]
		set IP [RADIUS::avp 8 ip4]
		if { $IP ne "" && $CALLID ne "" } {
			table set $IP [LB::server addr] 900
			log local0. "Radius maps $IP to [LB::server addr] for $CALLID"
		}
	}
}
 
when LB_SELECTED {
	log local0. "Selected [LB::server addr] [LB::server port]"
}
 
when SERVER_DATA {
	if { $CALLID ne "" } {
		persist add uie $CALLID
		log local0. "persist added for $CALLID to [LB::server addr]"
	}
}
