CirrostratusForward UDP traffic to different Pool using iRule
Hello, I made an iRule to forward traffic to other F5 Pool if source is Different , seems it does not work. If source is other than Defined in iRule expectation is traffic should be processed...
Hi Subrun,
Can you investigate ltm logs?
tail -f /var/log/ltm | grep ASAtestlogsimplified iRule:
when CLIENT_ACCEPTED {
switch [IP::client_addr] {
"10.7.10.10" -
"10.7.11.10" -
"10.7.12.10" -
"10.7.13.10" {
if { [LB::status pool ASA_Pool member 10.8.11.23 1514] eq "up" or [LB::status pool ASA_Pool member 10.8.11.24 1514] eq "up" } {
log local0. "ASAtestlog-1 | CIP: [IP::client_addr] | 10.8.11.23 is [LB::status pool ASA_Pool member 10.8.11.23 1514] | 10.8.11.24 is [LB::status pool ASA_Pool member 10.8.11.24 1514]"
pool ASA_Pool
}
else {
log local0. "ASAtestlog-2 | CIP: [IP::client_addr] | 10.8.11.23 is [LB::status pool ASA_Pool member 10.8.11.23 1514] | 10.8.11.24 is [LB::status pool ASA_Pool member 10.8.11.24 1514]"
pool Default_Pool
}
}
default {
log local0. "ASAtestlog-3 | CIP: [IP::client_addr] | 10.8.11.23 is [LB::status pool ASA_Pool member 10.8.11.23 1514] | 10.8.11.24 is [LB::status pool ASA_Pool member 10.8.11.24 1514]"
pool Default_Pool
}
}
}

CirrostratusI may be wrong but do we need an else loop because technically at ELSE you are assigning Default Pool. Or it may be for Programming Logic once an if there should be an ELSE ?
Also just note that my default pool is listening on 8514. I may not have clearly mentioned that.
I did this below still traffic is moving to DEFAULT Pool

switch [IP::client_addr] {
