Hello all,
Having trouble with slb. A server keeps cycling from operational to failed and back again ... over and over ...
Apr 18 19:22:48: %SLB-6-REAL: Real 172.22.2.125 (VPRDNS) has changed state to FAILED Apr 18 19:22:51: %SLB-6-REAL: Real 172.22.2.125 (VPRDNS) has changed state to OPERATIONAL Apr 18 19:22:56: %SLB-6-REAL: Real 172.22.2.125 (VPRDNS) has changed state to FAILED
But the probe never shows any misses:
wcq15-core-6513#sh ip slb probe name vprdns detail VPRDNS, dns, address = 0.0.0.0, interval = 15, faildetect = 3 VPRDNS, type = server target = 172.22.247.1:53, real = 172.22.2.125:0, virtual =
172.22.247.1:53 TCP state = OPERATIONAL, status = 1, operation id = 170 Server NAT outages = 0, failures = 0, successes = 208, tests = 0 current = never, cumulative = 00:00:00 target = 172.22.247.1:53, real = 172.22.2.125:0, virtual = 172.22.247.1:53 UDP state = OPERATIONAL, status = 1, operation id = 169 Server NAT outages = 0, failures = 0, successes = 208, tests = 0 current = never, cumulative = 00:00:00Here's the config:
ip slb vserver VPRDNS virtual 172.22.247.1 udp dns serverfarm VPRDNS idle 5 replicate casa 172.22.31.253 172.22.31.252 1029 synguard 200 inservice standby VPRDNS-HSRP ! ip slb serverfarm VPRDNS nat server nat client CLIENTS probe VPRDNS ! real 172.22.2.125 weight 1 inservice ! real 172.22.9.50 weight 1 inservice ! real 172.22.16.207 weight 1 inservice ! ip slb probe VPRDNS dns lookup prproxy.ourdomain.com interval 15
Also, the VIP only forwards UDP but the probe is testing both UDP and TCP. Can I control this?
Thanks,
