enabling/disabling node/member takes a lot of time
Hi,
I have to SNMP-trap receivers in a pool behind F5 bigip.
If I disable one node or pool member, traps are still coming for a minute or two. Sometimes even up to 10minutes or more, depends on how much SNMP traps I am generating while I wait for change.
If I leave it alone (not generating SNMP traps) it takes about a minute or two. In real life scenario SNMP traps would be at much higher constant rate.
It's UDP so there shouldn't be any level 3 logic involved behind, so why does it take so long to reload config which is written immediately (to bigip.conf and bigip_local.conf?
On other hand if a monitor fails, the takeover takes place immediately (as in specified timeout).
Config:
virtual address 192.168.1.80 {
floating disable
unit 0
}
virtual trap_vs {
destination 192.168.1.80:snmptrap
ip protocol udp
translate address disable
translate service disable
pool TRAP_pool
pool TRAP_pool {
lb method member ratio
action on svcdown reselect
snat disable
nat disable
monitor all gateway_icmp and Trap_port_opened and nms_database
member 192.168.1.7:snmptrap
member 192.168.1.8:snmptrap
