Hi I have seen this issue on a customers site before.
Do you have a gateway specified in the management interface?
If the two physical IPs of the controller and the "VIP" address are in the same VLAN then do not specify the gateway on the mgmt interface.
And also sometimes when I try to go to the management IP in a web browser, it crashes the active controller and thus cannot reach it on its own IP until a minute or so after.
controllers are connected to a HP2510G with the servers.
The HP2510 is connected to a layer 3 3com E5500G
The 3com connects to two core distribution switches HP 5406 ZL
Leonard Tsang, if your browser causing ZD to crash for whatever reason then it for sure needs investigations hence request to open a ticket with our support team with following info:
Debug file for both ZD's need to be collected.
which browser and its version?
Also pls chk if you are able to see this same issue on a different browser and on a different machine?
Is something specific being done which causes this or anything?
