NimbostratusiRule error elseif undefined procedure
Hello guys:
I am trying to configure an iRule that performs load balancing based on the client IP. I need to load balance based on entire networks and based on some specific IP address. Those entire networks are 172.16.0.0/16, 172.17.0.0/16, 172.18.0.0/16, 192.168.20.0/24 and others. On the other hand, some specific client IPs are 172.17.0.20 (to be load balanced to pool_B), 192.168.20.10 (to be load balanced to pool_C) and others. Therefore, I guess I need to configure an iRule considering a data group so I can group all the nets and then, configure the LB lines to the specific client IPs. The iRule I wrote is:
when CLIENT_ACCEPTED {
if { [class match [IP::client_addr] equals My_NETS] } {
pool pool_A
snatpool snat_pool_A
}
elseif { [IP::addr [IP::client_addr] equals 172.17.0.20] } {
pool pool_B
snatpool snat_pool_B
}
elseif { [IP::addr [IP::client_addr] equals 192.168.20.10] } {
pool pool_C
snatpool snat_pool_C
}
}But I'm getting this error: 01070151:3: Rule [/Common/test] error: /Common/test:11: error: [undefined procedure: elseif][elseif { [class match [IP::client_addr] equals 172.17.0.20] } {
I hope you could help me with this question.
Thaks.
What software version are you running? I wasn't able to reproduce the issue in v14.1.2.7.
I imagine you're running into something like what's described in this other DevCentral post.
You can try restructuring your iRule as follows to see if the error goes away:
when CLIENT_ACCEPTED { if { [class match [IP::client_addr] equals My_NETS] } { pool pool_A snatpool snat_pool_A } elseif { [IP::addr [IP::client_addr] equals 172.17.0.20] } { pool pool_B snatpool snat_pool_B } elseif { [IP::addr [IP::client_addr] equals 192.168.20.10] } { pool pool_C snatpool snat_pool_C } }
