Can You Obtain The IP Address Of Network Switch Through Media Gateway

Turtlepuke · Feb 2, 2023

Question:

I'd like to catalog the IP addresses of all the network switches at various sites that our Media Gateways are plugged into.
From the command line of a gateway, is there a way to determine the IP address of the switch it's plugged into? Would it just be the default gateway? Or something else?

If so, what is the command to determine this?

Thanks!

Not generally, switches and devices are layer2 so will have MAC address tables

If the switch supports it you could try LLDP on the gateway:

show lldp

jimbojimbo · Feb 14, 2023

If the network team is sharp, they will not have the network switch IP Address on the same VLAN/Subnet as the media gateway. Assuming Layer 3 routing in the switch, your gateway is going to be assigned to an interface on the switch just not the same one as management. Basically, you shouldn't be able to pull the IP Address of the data switch.

Media Gateways types may have unique commandline syntax.
g700 stacks are quite different than g350, g430, g450

Below are some examples to try.

MG-001-1(super)# show system
MG-001-1(super)# show interface
MG-001-1(super)# show ip rout static
MG-001-1(super)# show voip
MG-001-1(super)# show mgc
MG-001-1(super)# show mgc list
MG-001-1(super)# show mgp recovery
MG-001-1(super)# show mg list_config
MG-001-1(super)# show sync timing

Below are examples with output.

Code:
