Re-IPing CM and G700s

This past week I worked on setting up a couple of Avaya Aura Media Gateways G700s or Cajun Switches as they were known. Both P330s were already configured with existing IPs and other programming parameters. That’s when I though of writing a Blog Post about Re-IPing CM and G700s; to help you alleviate some of the pain I went through myself trying to re-fresh old commands and settings.

Three things to look out for:

• 1.- Verify your Stack and Media Gateways Processor’s Configurations
• 2.- Updated your Avaya Aura Servers IP Addresses
• 3.- Configure your Interfaces

1.- Verify your Stack and Media Gateways Processor’s Configurations

Before you start verify your settings and document all IPs and existing Configurations; such as P330’s IP Address by running the command “show interface” under P330-configure# mode.

Then run the “Session MGP” command to access the Media Gateway Processor.

Once logged into the MGP, check both MGP’s and voip v0’s IP Addresses by running the command “Show interface MGP, and show interface voip v0”.

2.- Updated your Avaya Aura Servers IP Addresses

Follow these steps=

• Check your connectivity by pinging the service’s port IP Address 192.11.13.6.
• Connect to System Platform using your internet browser, once logged in, navigate to > Server Management > Ethernet Configuration.
• Update the SPDom0, SPCdom, Utility, CM’s Servers IP Addresses.
• Lastly don’t forget to update the Subnet Mask as well!…I made the mistake of forgetting it and cause me extra time troubleshooting.

3.- Re-IPing Media Gateways – G700 / P330 Cajun Switches

The G700s have multiple layers that need to be configured with IP Address. The physical media gateway interfaces are called inband, then the MGP is your H.248 controller, the VOIP is your media processor responsible of converting your TDM traffic to RTP packets and back., and the Stack allows communication between all media gateways.

inband configuration

Login to your Media Gateway, under configure mode type the “nvram init” command to reset your Media Gateway back to factory default, this should take you a couple of minutes.

Once defaulted follow these steps=

Assign your P330 inband’s Interface IP Address and don’t forget to include your new VLAN ID before typing it’s IP Address with Subnet Mask.

P330-1??(configure)#  set interface inband vlan-id IP Address Subnet mask

Now assign your Default IP Route

P330-1??(configure)#default ip route 0.0.0.0 x.x.x.x (x= Router address)

Reset the media gateway

P330-1??(configure)#reset

Configuring the stack

When configuring a second MG700 in the Stack, type the “reset stack” to reset the entire Stack”.

Assign the stack’s default gateway

P330-1??()# set ip route 0.0.0.0 x.x.x.x (x= default gateway or router address)

Configuring the MGP

type the command=

P330-1??(configure)#session mgp

login, then set the mgp default gateway

MG-???-1(super)# set ip route 0.0.0.0 0.0.0.0 x.x.x.x

Configure the MGP VLAN

From the configure mode type=

MG-??-1(configure)# interface mgp vlanid ipaddress subnetmask

Configure the VoIP

MG-??-1(configure)#set interfcae voip v0 ipaddess (no need for subnet mask or vlan id when running this command)

Reset the MGP

MG-???-1(super)#reset mgp

Reset the Media Gateway

P330-1(configure)#reset

All IP Addresses are already set on both CM and MGs

Note- Don’t forget to remove all Stacking Module Cables to configure each media gateway separately and follow the same steps shown above.

Configure Dom0 VLANs

Finally to update the VLAN ID on your System Platform run these steps from the #root level login=

 # /opt/avaya/bin/change_vlan

# /opt/avaya/bin/change_vlan -l (This command will display the existing VLAN ID assigned)

# /opt/avaya/bin/change_vlan -y 89 (This command will assign VLAN ID 89)
