NLB config

[Amphrodite1]

When i configure NLB using a teamed network adapters , i am able to ping the clustered ip address(Primary address), but never able to ping the individual ip addresses given in the TCP/IP properties( Static address)from outside.We are using cisco switch 2900
Teamed ip 1-10.6.15.50
ip 2-10.6.15.51
Cluster IP -10.6.15.52

Please help

If you are doing NIC teaming, you should be setting up a port group/channel/trunk and only using one IP.

Basically setup an etherchannel on the switch for the ports that your nics are plugged into, and configure the nics for etherchannel. One ip is used then.

NLB, ick. If it's what I'm thinking this uses 3 MAC addresses. One for the cluster to receive, and one for each server to reply with.

The switch never sees the RX MAC as the source of the packet so it never binds it to a port. The result is every packet destined for that MAC is broadcasted.

If you insist on using it I would HIGHLY recommend giving the cluster it's own vlan so everyone else doesn't have to here it's traffic.

All the setups I've worked on have a seperate management network between the cluster devices so they can argue on who is going to answer the incoming requests. Sounds like you have some server side configuration problems.
