SGE2000 Locks up when adding IPv4 Interfaces to VLANs

I have an SGE2000 (latest firmware, 3.0.0.18, boot 2.0.0.03) on which I'm trying to configure some VLANs. After having defaulted the configuration to factory settings, I've performed the following steps:

  1. Set the operating mode to Layer 3
  2. Set the stacking mode to Standalone
  3. Rebooted
  4. Connected via web interface (192.168.1.254, VLAN 1)
  5. Created VLAN 1000 "Test VLAN"
  6. Assigned ports 13, 14 and 15 to VLAN 1000 (untagged)
  7. Added IPv4 interface 192.168.4.254 to VLAN 1000.

As soon as I click "Apply" in the popup window, the main web interface tries to reload but fails, and the unit stops responding to pings on 192.168.1.254. This happens when using both the web and telnet interfaces, and the only way to reconnect is to reset the switch.

I'm not sure if I'm doing something wrong, or whether there is a problem with my unit. Any help you can provide would be greatly appreciated!

Hi Charlie,

I am not familiar with SGE2000, but can you try configuring a lower number vlan id i.e. 10, 20, 75,etc.. and test again.

Hi Reza

I have tried using many different VLAN numbers, from 2 to 1000, all have the same effect.

Charlie,

Besides the Apply command is there also a save command?

Maybe you have to apply it, than save it?

Hello,

Have you tried to connect a PC to one of those VLAN 1000 ports with IP of

192.168.4.x and access 192.168.4.254? I guess this platform supports only

one L3 interface for management.

Hope this helps.

Hi

I have tried connecting to one of the VLAN 1000 ports and I do not get a reply from 192.168.4.254. It's as if the configuration interface just falls over as soon as the changes are submitted.

Hello,

Did you set VLAN 1000 as management VLAN?

Hi

No, I haven't set 1000 as the management VLAN - primarily because I do not wish to change the management VLAN from the default. All I want to do at this stage is add additional interfaces for each new VLAN to allow me to do InterVLAN routing...

Thanks,

Hello,

What is the switch mode? Have you set it to L3?

Hi

Yes, I have set the mode to Layer 3 and rebooted the switch. The menu structure of the web interface changes to match L3, so I know the mode change has been successful.

Re: SGE2000 Locks up when adding IPv4 Interfaces to VLANs

Thank you for your help guys. I managed to solve it eventually.

I had to change the default IP address of the SGE2000's VLAN1 to anything other than 192.168.1.254 using the console. The switch immediately starts responding to the new IP address on VLAN1, whereby I can log back in and add a second interface to VLAN10/1000/etc/etc without any problems.

Kind regards

Charlie
