There are a pair of MDS 9509 switches whose management addresses are 172.16.2.197 and 172.16.2.198.
When we try to manage these Devices through Cisco device manager, the first device opens up without any problem, but when the second 9509 is opened in Cisco Device Manager, it fails giving the following error message:
"Open udp transport failed: Address already in use: Cannot bind"
To get around this issue, if we close the first interface to the 9509 switch, then we are able to open up the second 9509 in Device Manager.
We have this problem only in Cisco device manager. If we open one switch in Cisco device manager and the other switch in Cisco Fabric Manager, it works.
Also, we can telnet to both the devices successfully at a time.
The device manager in use is 4.1.
Please find enclosed the sh version outputs for your kind reference.
Can you please help me understand the cause of this issue?
Thanks a lot
