I am trying to configure a CSM to use Load-Balancing Advisor on z/OS as a GWM.
I have configured the CSM vlans as such:
vlan 19 client
ip address 176.11.16.11 255.255.240.0
gateway 176.11.16.235
!
vlan 9 server
ip address 176.11.48.11 255.255.240.0
The serverfarm I'm using
serverfarm DMP50030
no nat server
no nat client
bindid 65520
<servers here>
and my dfp agent:
dfp
agent 176.11.48.104 3860 65520
The problem is that the dfp agent fails to connect to the GWM.
cs233#sh module csm all dfp detail
---------------------- CSM in slot 11 ----------------------
DFP Agent 176.11.48.104:3860 Connection state: Trying to connect Retries: 7
Keepalive = 65520 Retry Count = 0 Interval = 180 (Default)
Security errors = 0
The GWM is definitely listening:
LBADV 00009FB9 Listen
Local Socket: 176.11.48.104..3860
Foreign Socket: 0.0.0.0..0
When I sniff the 176.11.48.x LAN, I don't see any packets for port 3860 so I'm not sure how the CSM is attempting to connect to the GWM. How does the CSM determine which vlan to connect to the GWM? Does the GWM address need to be layer-2 adjacent to the CSM? Is there any way to force the CSM to use normal IP forwarding to contact the GWM? I can ping the GWM address with no problem at all.
