CirrusOne node is down in standby unit
I deeply confused. I have active standby pair of F5. there are about 40 pools and 20 nodes. All the nodes are up in active and all the node are up in passive accept one. I don't understand why this o...
I am getting a ping response from the node after 90 failures.
what does "after 90 failures" mean?
If I am not getting ping response then I can not get TCP half open (monitor) response as well.
if bigip does not get response, can you check if server does send response?

Muhammad_Irfan190 failures means after drop 90 pings one ping succeeded in getting response. The mac entry learned for that node by standby unit is different then mac entry of active the rest nodes mac are same. When I looked for that mac address in switch it was pointing towards active F5 unit, What is this. I tried to clear dynamic entries but of no good. That entry is still there pointing towards active F5 for that node. Which means standby unit is searching for that node through switch to active unit. ahhh- nitass_89166are you using vlangroup?
- Muhammad_Irfan1yesssss. is this the problem? here is my network diagram http://imgur.com/gallery/ItMTFum/new
- nitass_89166is this relevant? sol11812: Failure to specify non-floating self IP addresses in the VLAN group Proxy Exclusion List may cause misdirected monitor traffic https://support.f5.com/kb/en-us/solutions/public/11000/800/sol11812
- Muhammad_Irfan1Nitass you are genius, you solved my problem. Exactly this was the problem. Just one thing more, proxy exclusion list already had floating ips in active unit and standby unit had no ip. Is this ok or should i remove floating ips from the active unit list. I never added foating ips in this list so may be its default that active unit have floating ips in his list.
- nitass_89166i do not have much experience on vlangroup. anyway, according to the sol11812, i understand it could be non-floating self ip of peer unit.
- Muhammad_Irfan1I have manually added non floating ips of peer unit but floating ips were there in the active unit already. May be that's how it works, but thanks alot
