We recently moved a Brocade SilkWorm 200E fibre switch to a new VLAN in our Data Centre. After the move, the web interface is not accessible anymore. I can ping the management NIC on the switch, so I know it is online. I think this may be due to some ACLs on the new network/VLAN.
There are ACLs to allow Ping, HTTP, and HTTPS through. I'm thinking the ACLs block whatever port the Java switch management uses, but I can not find what port this is in any documentation.
Does anyone know which port the Java switch management app uses?

are you able to login via ssh or telnet on that switch?
I think a ping test is only useful if you know that the switch IP address on the new VLAN was free and unused before you moved the switch.
As far as I know is that you only need from client to switch:
Port 22 TCP SSH SCP
Port 23 TCP Telnet
Port 80 TCP HTTP
Port 443 TCP HTTPS
Port 161 UDP SNMP
From switch to destination
Port 20 & 21 TCP FTP
Port 123 UDP NTP
Port 1812 UDP RADIUS
Port 1813 UDP RADIUS
As far as I know there are no Java ports required.
A client to DCFM is using some other ports but not the plain Webtools.
I think the best way to get out of this issue is to ask the network/firewall admin to have a look in the log files which sessions are rejected.
