Aruba 2530-48G switch unable to access to web interface

Hi all,

I am using three 2530-48G switches named SW2, SW2 and SW3. In that, port 45+46 of SW1 trunks to 45+46 of SW2, and port 47+48 of SW1 trunks to 47+48 of SW3. Everything is ok untill i add a new VLAN in SW1 (not assign port to VLAN yet).

The network operates normally, but something wrong with SW1:

        - Can ping to SW1 but cannot  access by web and ssh interfaces, only access through console menu.

        - Cannot remove new added VLAN in console menu 

Actually i always operate them just by web-interface. So it so difficult for me with others. Please help me to get over this problem?

Thanks.

Re: Aruba 2530-48G switch unable to access to web interface

Hi,

 

please post config at least of SW1.

Since WebInterface is not working:

  • Go to console
  • Change from menu to CLI
  • issue "show config"

Provide results here.

Hi

Which VLAN Id you added?

 

Generally adding a VLAN (without eventually assigning to that VLAN an IP Interface and untagging/tagging port(s) you need on the relevant switch) has not such damaging impact (not connecting anymore to Web Management)...at least if you simply created it as you wrote.

 

The output of show running config would be of help to better diagnose what's going on.

Re: Aruba 2530-48G switch unable to access to web interface

Hi,

 

you configured the new VLAN as "management VLAN". The switch will accept management connections only in that management vlan.

Since management vlan has some other difficulties, I'd suggest, you do not use this function for now. 

 

So remove that configuration and you should be able to connect again.

 

"no management-vlan" should be enough.

 

Regards,

 

Jörg

Re: Aruba 2530-48G switch unable to access to web interface

As Jörg wrote, the problematic configuration line is:

 

management-vlan 140

 

You have not configured any port to be untagged member of that VLAN (and you didn't assigned any IP to that VLAN 140)...so, basically, you locked out.

 

Remove the above line from configuration file and reload it via Console port and you should be able to connect again to your Aruba 2530 using the configured IP 192.168.0.254 through any of its ports (1-44 <- untagged members of VLAN 1).

Greetings!

 

Going into a bit more detail on the management VLAN — one thing to keep in mind if you do plan to use this feature is that the management VLAN does not participate in switch IP routing, so if your management workstations are on a different subnet from the management IP address, the switch will be unreachable.  If your goal is to limit management access to the switch, you may want to consider using the ip authorized-managers command or ACLs as an alternative.
