1 TopicBIG-IP DNS iRule issue with static variable
I am trying to develop an iRule bypassing DNS processing when a DNS request matching a wide ip comes via a specific listener on our BIG-IP DNS. Code is below: when RULE_INIT { set static::ul_ip "10.X.Y.Z" set static::ul_debug true } when DNS_REQUEST priority 100 { if { [IP::addr [IP::local_addr]/32 equals $static::ul_ip]} { DNS::disable all #apparently event disable is no longer accepted? #event disable if { [$static::ul_debug]} { log local0. "DNS Request [DNS::question name] triggered bypass" } } } This rule is meant to be applied to specific wide ip's (for reasons). When this rule is applied and tested, I am seeing the message below in /var/log/gtm: Apr 30 12:06:37 somebigipdns.nope.com err slot1 tmm[18454]: 011a7001:3: TCL error: Rule /Common/ul-bypass-rule <DNS_REQUEST> - can't read "static::ul_ip": no such variable while executing "IP::addr [IP::local_addr]/32 equals $static::ul_ip" I'm completely unclear on why the TCL error is occurring. For bonus points, any idea why 'event disable' isn't working in the DNS_REQUEST event? This message shows up in /var/log/ltm unless 'event disable' is commented out: Apr 30 11:11:27 somebigipdns.nope.com err slot1 mcpd[6981]: 01070151:3: Rule [/Common/ul-bypass-rule] error: /Common/ul-bypass-rule:23: error: [undefined procedure: event][event disable] Thanks in advance for any assistance provided. - RSolved70Views0likes2Comments
