G250 Console Connection

[Stinney]

Ok, totally aggravated. I have an old G250 I setup a long time ago. I know that I used the Gateway Installation Wizard to set it up. I must of had a computer with a DB9 connection, but don't any more.

I've tried connecting using an USB to DB9 connector to the Avaya DB9 to RJ45 connector and the flat console cable that Avaya gives out in the droves with each gateway.

I cannot get the GIW to connect. The COM port is 3 for the USB, are there any other settings for the COM port I need to be checking?

I may be forced to look at pinouts and do my own cable, but I don't want to go through all that and still not be able to connect.

I can't access the gateway remotely anymore as I blew away the IP on VLAN 1 as part of trying to test if that could be done remotely.

If you didn't 'copy run start' can't you just power cycle it to get the old config back?
Otherwise I can't help, sorry.

From my notes. I've also attached 2 ways to make your own console cable. The first from scratch. the 2nd is by modifying a cisco console cable.

Connect a Avaya console cable to laptop. In my case I used a trendnet serial to USB converter.
Set putty to serial and com4. Click connect.
Then log into the G450.

BIS, thank you. I'm officially turning in my Avaya card...... I should learn not to do this stuff late at night and when I'm cranky after working all day. Of course taking the "IT Crowd" approach and turning it off and on again worked.

phoneguy55 I doubled checked I was using the correct DB9 adapter, toned out all the pins and they were correct. I have the flat crossover that Avaya provides and it was also pinned out correctly. I plugged the same USB to DB9 into the same USB port on my PC (it's using COM3), plugged in the same DB9 to RJ45 adapter used the same cable and connected it to the Console port and wouldn't you know it the stupid thing decided to work now, don't know why.

Thanks to both of you. I think I need to take a vacation and clear my head.

Time to get rid of the G250/G350/G700/G650 devices. Major security concerns. Most security teams won't even let a G700 on the network anymore.

We're working on getting rid of all our gateways and centralizing circuits to our SIP head end and using centralized G450s.

So the answer to my question is an absolute no. You can't remotely change the vlan 1 IP address. In any scenario possible, you have to have someone on site to perform some physical connection(s). Out network team is going to love to hear this news as they are changing the IP subnets in a bunch of our locations. A lot of them don't have anyone to perform work/connections to the local gateways, so we will have to contract out the work ($$$).

Stinney,

We remotely change the IP address of G450's often. We get notified by our networking team that they are moving from 1 subnet range to another. We reconfigure the G450 remotely. copy run start. Reset media gateway. Then wait for the networking team to reconfigure the LAN switch. Then some quick tests. I can't speak to the older gateways but this 100% works on G450s.

phoneguy55, you SSH into the gateway don't get dropped after entering 'no ip address'?

 

[Stinney]

Using PuTTy using SSH, I went into the gateway, as soon as I put in the no ip address for the VLAN 1 the connection stops responding.

There's a couple of options but some involve having someone onsite to do simple work.
1. If there's a Windows server onsite, connect a console cable from the gateway to the server.
2. If there's a server onsite with multiple NICs, connect a cable from the services port to the second NIC and set it up for the 192.11.13.x network
3. In the gateway, create Vlan 2, program the new IP address to it and assign the standby interface to it. (You may have to disable port redundancy if it's set up). Have the network team do their conversion and when the network comes up you should be able to log into that new IP address. After that, do all of the changes you wanted to do for Vlan1.

If you have an LSP installed then you have a little more different process to follow but I've done it before at several sites remotely.

Remotely changing IP address of G450

1. Take a backup of the config.
# copy running-config ftp filename ip
where filename is the filename and IP is the IP address of the FTP server.

2. Modify the file on your PC. IP address, subnet mask, default gateway and hostname. MGC list can be done later.
3. Push the file back to the G450.
# copy ftp startup-config filename ip
where filename is the filename and IP is the IP address of the FTP server.
After the above command you should still be connected (we only updated the startup config, not the running config).
4. Reboot the G450
# reset chassis
5. If necessary, you can now change the LAN port VLAN, etc..
