connectivity to a switch (X440)

[Jason_Short]

Hi,

I have a strange problem and wondered if someone can shed some light on this for me.

We have x440-48p which in-situ and 'working'.

I am trying to allocate a couple of ports to a particular VLan.

When I try to connect directly to the switch using RJ45 and Telnet I cannot gain any access. My system doesn't even show the login screen and I am unable to ping the unit.

However if I connect to one of our other Extreme Devices I can then connect to the problem device using a web browser and can see the basic config details.

When I click on the VLAN configuration it doesn't list any ports being associated with the VLAN.

If I click RELOAD I am presented with the following message:

"There are some unsaved changes in the form. Do you want the form to be updated?"

I click on Yes and the receive the following:

"Do you want to apply the changes to "VLAN NAME" Note: Modification to the IP Addresses will first un-configure the current IP Addresses."

Again I accept the changes.

However, the problem device still doesn't show the ports associated with the VLAN, I have to press RELOAD again and we go around in a loop.

Is this sort of behaviour correct or am I doing something wrong?

Many thanks in advance

Hi,

Telnet is enabled by default, so if you can't connect that means:
a) telnet has been disabled (and maybe ssh only is enabled). As you can access by web, which is not default, that's a possibility
b) you are not on the correct vlan / IP subnet (maybe there's no IP at all).

When you say you connect directly to the switch in RJ45, do you mean in the Mgmt port, or an inband port? Are you sure the Mgmt port has an IP address configured, or that the inband port belong to a vlan with an IP configured? Are you, in either case, on the same IP subnet?
