enabling lldp

[suthomas1]

Hello,

Does lldp support on cisco switches depend on version.

We have a 3560-48PS, running 12.3.

It does not allow using lldp run to be used.

Please advise. Thank you.

Just adding another query , is it possible to increase the poe delivered on specific ports if the unused ones are disabled from using inline power.

Hi,

It should not matter what version you are running.

config t

lldp run

should work fine.

What is error message you are getting?

Just adding another query , is it possible to increase the poe delivered on specific ports if the unused ones are disabled from using inline power.

No, depending on the module, there is a limited amount of wattage (poe 30w, upoe 60w) that is assigned to each port. You can't go above that number.

Thank you. The option is not presented, as below.

SW(config)#lld
SW(config)#lld?
% Unrecognized command
SW(config)#lld

on the poe aspect, i have turned off poe on some ports. This is to see if some of the devices, requiring more power than usual 15w, will get them.

Will upgrading the IOS help to allow lldp feature & in-turn increase the poe power delivery or is it strictly based on the switch model?

Hi!

The version you are running is not supported and you must have at least 12.2(55)SE to run lldp. See this Link:

Thanks, will upgrading the version to support lldp also allow the poe to be higher than the current 802.af?

Or is the actual power imparted limited to the switch & independent of software.

No, the POE is part of the hardware. Software can't change that.
