Hello All,

i ran netstat command in one of our server ...

momsrv01:/ # netstat -in
IPv4:

I need some clearifications about some lines like [ lan2:1 ] ??

I'll have a wild stab in the dark and guess that this node is part of a cluster of some kind.

My guess would be that lan2:1 is an additional IP address associated with an application package that runs on this node and some other node. The IP adddress 172.20.10.11 is a virtual IP adddress, and if the package or node fails then the application and IP address is moved to another node.

Do you need further clarification than that?
