Accidently disabled L2 switch port - how to re-enable

[mitelrocks]

Hi everyone -

Tech here accidentally disabled the L2 switch port instead of disabling VLAN tagging.  As soon as this was done, all IP connectivity to the MCD controller was lost (of course!).  We have no earthly idea how to turn back on the L2 switch port - this has to be done in Vxworks somehow. We have rebooted the box and noticed that during vxworks booting, we noticed that there is a warning message that the L2 switch port is turned off (constant pings to the MCD controller confirm this).   Does anyone know of a vxworks command to turn back on the L2 switch port.  We noticed there is a command called "ifShow", and it lists motfcc as one of the network interface cards..but that's it.   We have a recent backup of the database,  and we are prepared to re-install MCD software if we have to.  Just doesn't seem right that the MCD software allows you to easily disable the port without being able to re-enable it quickly.   Box is a MXe III running MCD 5.0.

Pretty sure this can be done from the RTC command shell (or serial port in this case), but I don't know the command. I would  have the tech get on the phone to tech support ASAP, once he gets to a tech on the phone the fix should be pretty quick.

I believe the command is
vlan_off
or vlan_on

This will re-enable the L2 switch? Thought the OP said they disabled the whole switch, not just VLAN support.

Dunno.  It's all I've got at the moment though.

We tried the 'vlan_off'  /  'vlan_on' commands - and vxworks does confim the command, but it does not 'enable' or 'disable' the L2 switch port.   We issued the command 'vlan_off'  and then rebooted the MCD box - no effect.

From the command line can you ping the controllers IP?

No, from a Windows box here, we cannot ping the controller IP.

Little more detail -  we are consoled into the MCD controller.   On a Windows box, I setup a constant "ping" going to the MCD controller (but no ping replies back).   OK,  so we turned off the MCD.  After you turn on the MCD, you see the memory check and system check, then Vxworks starts (press space bar, 7,6,5, etc)  as soon as Vxworks starts up the pings work for about 4 seconds and then they stop, and they never start up again.  At the point that the pings stop we see in the console window the status that the L2 switch was disabled.   Will reach out to Mitel...

I suspect you're going to be reloading.

Put a serial cable on the console and watch what happens when it reboots.
9600,8,N,1

On second thought, it's obvious you already have a cable on it.
Try pinging itself.
The command would be
ping "<ip addr>"

Thanks for the replies!

A ping to itself shows no replies (from vxworks command prompt), after system boots.   Planning to re-install....

Make sure the L2 switch has an IP address.....

[acejavelin]

Why would there be an option to disable the internal L2 switch? That is kind of ridiculous if it locks you out of the switch entirely... There has to be an easy way to re-enable it... did you call tech support?

Enter bootChange and hit return through the options.
Post the results here.
Let us know what the IP address should be.

I'm suspecting the IP was changed.
