Nimbostratussend to pool-member by port-range
I have an problem to get it to work right.
I have made an VL om port any, with an default pool.
some ports have to go to one server ande some ports have to go to the other server. I have made an iroule (paste belowe) but it only works evry 2. time. I am not sure the iroule have any effekt, it might only use the LB bye the VL ???
when CLIENT_ACCEPTED {
set srv_port [TCP::local_port]
if { $srv_port >= 6740 and $srv_port <= 6749 } {
pool mpapp-pool member 10.10.66.22 $srv_port
log local0. "Client sent to $srv_port"
} elseif { $srv_port >= 6830 and $srv_port <= 6839 } {
pool mpapp-pool member 10.10.66.21 $srv_port
log local0. "Client sent to $srv_port"
} elseif { $srv_port >= 6860 and $srv_port <= 6869 } {
pool mpapp-pool member 10.10.66.22 $srv_port
log local0. "Client sent to $srv_port"
} elseif { $srv_port >= 6880 and $srv_port <= 6889 } {
pool mpapp-pool member 10.10.66.21 $srv_port
log local0. "Client sent to $srv_port"
} elseif { $srv_port >= 7000 and $srv_port <= 7009 } {
pool mpapp-pool member 10.10.66.22 $srv_port
log local0. "Client sent to $srv_port"
} else {
log local0. "no match on port $srv_port"
}
}

The rule looks fine. What does the client see on the request which fails? What logging do you see for a failure?

Michael_60521I can see every 2. connection are LB to the other server (the wrong one), it seems for me that it is working with the default pool and not the iRoule.
I have tryed to make an other iRoule (paste below), this one is working with no default pool, but the iroule might be written in an other way ..... : (the pools in this iroule have only one of the servers..)

}- Michael_60521this is workin without an default pool :-))

} - hoolioThat makes sense. A request which doesn't match any condition in the rule would be sent to the default pool of the VIP, if one is configured. If there isn't a default pool, the request will be dropped.
Aaron - switch will consume less CPU than the elseif
