My network is as follows
In my scenario , servers and vip resides in same network . Default gateway of servers are Core switch .
Following is I have done
1) Created a internal VLAN ( etherchanneled)
2) Created SelfIP- Non floating ( 172.16.4.40)
3) Created SelfIP - Floating (172.16.4.43)
4) Created VIP - 172.16.4.45
default gateway of F5 is 172.16.4.1 ( core switch which is the default gateway of servers too)
I have created SNAT ( autonat) on the VIP .
issue what i am facing is when i access the real IPs 172.16.4.31 and 172.16.4.36 on port 8006 portal works with out any issues . Nevertheless when i access it through 172.16.4.45 which is VIP , clients are not getting any response ( getting as connection interrupted)
I have no clue why even after SNAT this issue is happening. i have target of finishing this task tomorrow and still i am no where in resolving this.
Can somebody help me out in this?
thanks a ton in advance
i couldnt see any out packet on snat statistics as well
Thanks Kevin for your prompt replies.
1) verify your etherchannel configuration
I have created trunk (1.1 and 1.2) and allowed vlan # on it this VLAN is same as the serverfarm and VIP . I havent configured LACP on it. On the cisco switch side , i have configured etherchannel and mode has been configured as desirable. Is it a wrong config ? do i have to add anything further?
2) make sure you can ping these servers from the F5 and that ARP addresses are correctly resolved,
I am able to ping the all the servers from the load balancer . However , initially i was not able to ping the default gateway and it was not showing the arp as well. When i statically added the mac-address of the Core switch , i was able to reach the gateway. I thought that this would be some kinda arp issue. but couldnt relate it to any etherchannel related issue as "only" the gateway |from the F5 box"wasnt reachable but from anywhere in the lan ( other subnets as well) i was able to ping the VIP. (172.16.4.45)
3) observe your /var/log/ltm log data for any possible anomalies
Couldnt actually observer any other than abnormal other than a real server issue which was genuine and has been taken out from the pool.
Any clues , where should actually peek in to , since i have no clue , how should i address this tomorrow :-(
Clients are in different segment (172.16.11.x/12.x/13.x etc)
Servers are in (172.16.4.x and on VLAN 4) , VIP is also in (172.16.4.x same VLAN) . Customer dont wanted to change the gateway of servers while introducing the F5 box , that is the reason being designed in this one arm mode and they are not ready to introduce a new network for the VIP range and hence the servers and VIP are in the same network.
from the F5 box , i am able to reach the servers which are in 172.16.4.x network how ever i am not able to reach the gateway 172.16.4.1 until and unless i add a static arp entry.
is LACP compulsory if i use trunking on f5 ?
1) Configuration is attached herewith.
2) ARP entries are correct and has been verfied.
3) No irules it is very basic config. Since i am not able to proceed with minor load balancing configuration ,i am not in a position to proceed with anything.
yes this is first configuration on this box ,
there is no other VIP configured on this box
Default route ( gateway) has been configured , but not pingaeable until and unless i put static arp entry !!
