LDwin on 2260

[bdelozier]

Hello everyone,

I'm not sure if it's the right place to ask my question, sorry if it's not the case !

I usually use a software called LDwin to help me identify where my cables are connected.
And by default, on the Alcatel equipment, lldp information are not available, I did a little search about it, and find few cli commands that work well for what I'm doing on OS6360.

There is the command that I use :
lldp chassis tlv management management-address enable
lldp chassis tlv management port-description enable system-name enable system-description enable

But when I did the same cli command on the OS2260, I got no result. (To be sure I did the test directly connected in the front of a OS2260)

Have you any idea on how I can get this to work on my OS2260 ?

Thank you for your time

With this command the switch will offer to all lldp neigbors the wished informations. Per default only the mandatory lldp attribues will be sent. Here you configure the optional attributes.
Have you other ALE switches connected? Than you can test with "show lldp remote system" the received information.
Maybe there is an mistake in the 2260 - I never tested it with them. Than an update is useful.

I was curious so I took a look, and this is an output comparison between a network with 2220 switches and a different site with 6360 and a 6900.

On the 2220:

Hello guys,

First, thanks for your help !

So I did the check on a 2260 that is connected to a 2260 and a 6360.

Code: Select all

      Management IP Address       = 192.168.200.68

On the 2260, we are not able to see the specific port where it's connected

My LLDP configuration :

Code: Select all

GARE-LTP-N2-2 show configuration snapshot lldp
! LLDP:
lldp nearest-bridge chassis tlv management port-description enable system-name enable system-description enable
lldp nearest-bridge chassis tlv management management-address enable

I will try to add all the command given by cristek and keep you informed.

Once again, thanks !

So indeed, it work after put more command :
I'm not able to tell which one worked

      Capabilities Enabled        = Bridge Router,
      Management IP Address       = 192.168.200.68

I will be able to have a physical access on the switch tomorrow, so I will try again with LDwin and keep you informed.

Thanks for your help !
