Cisco LMS 3.0.1 device discovery

[Peter Valdes]

Hi,

Just a quick question on device discovery using CDP and SNMP v2.

Scenario:

Site A consist of the following cisco device

Router - 10.10.10.1

Sub-interface VLAN 1 - 10.1.1.254

Switch 1/Vlan 1: 10.1.1.1

Switch 2/Vlan 1: 10.1.1.2

Switch 3/Vlan 1: 10.1.1.3

INTERNET connection

Site B

Router - 20.20.20.1

Sub-interface VLAN 1 - 10.1.1.254

Switch 1/Vlan 1: 10.1.1.1

Switch 2/Vlan 1: 10.1.1.2

Switch 3/Vlan 1: 10.1.1.3

Site A and B uses the same network IP address for the switch stack on VLAN 1 and is only separated by the router and the Internet. If the LMS server is on SITE X, is it possible to discover the switches on both Site A and B?

Site X has VPN connection to Site A and B via VPN.

This is not possible. Every device must have a unique management address in DCR. You can add the two routers to site X's LMS server, but not the switches at each site. They will not be properly managed.
