re-IPing a LSP site

[oscar01]

I have to move the Avaya equipment to another network at one of my LSP sites. Below are the steps I plan on doing but I'm not sure if they are complete. The site has a G700/S8300 and 4621sw sets. It connectes back to a pair of S8730s running CM5.2.


1) Change option 176 in the DHCP scope with the new S8300 IP address for the MCIPADD and IP address of the new VLAN (L2QVLAN = x) [we only use 4621sw sets]
2) Change the IP address, subnet mask, default gateway of the S8300, G700 P330, MGP, VoIP
3) Change the MGC list in the G700 replacing the IP address of the S8300
4) Add new IP address range in IP-network-map. (We will keep the network region and location the same)
5) Route new network at all sites on Cisco routers.

Does this check list look complete? I don't have physical access to the site so I can't run the Avaya Gateway Installation Wizard. How do I change the IP address of the S8300, G700, MGP and VoIP? Once I change them I'm sure I'll lose connectivity. Will someone need to reboot the G700 or do I issue a reboot command after I change the addresses? Thanks

You need to have onsite access to a Windows PC, that has 2 ethernet interfaces, 1 is connected to the company's LAN so you can RDP/PCANywherer to it, the 2nd interface will be set to a fixed ip of 192.11.13.5/30, and you will connect to the S8300's "service port" of 192.11.13.6 on the processor

Once connected to that you can use the web interface on the processor, you can telnet/SSH to it (192.11.3.6), and once you are ocnnected to the S8300, you can then telnet to the stack processor (telnet 127.1.1.1) or to the MGP (telnet 127.1.1.11) these are internal IP's and you will be able to get to the gateways using these.

and yes, once you change the LAN IP's you would loose connectivity to them, so you need to do this out of band... you can also connect the serial console cable to a serial port on a PC and use "hyperterm" to get to it.

Of course you need someone onsite to get all of these connections made in advance, and to install perhaps a USB Ethernet adapter, if you don't have a spare NIC in the PC you will be using onsite.

I have done it this way many times, and this is how I would recomend you go about it, or else you will have trouble.

Thanks Mitch! Do you know if I can connect the serial console cable to a Lantronix console server that is accessible throughout the WAN? I've tried this in the past but I either had the wrong serial adapter or the wrong pin out on the RJ45 end going into the Lantronix.

you can, if you have the correct AVAYA console cable/wiring, however, the serial console cable ONLY gets you access to the G700, it won't help with changing anything on the S8300, this is why I would just go with the "service port" using a 2nd NIC card on a local PC, you will be able to get to everything that way.
