MS Surface trying to run LLDP script for phones

DH1 — Thu, 27 Apr 2017 21:39:00 GMT

We run LLDP scripts for our MITEL VOIP phones and I have noticed that Microsoft Surfaces running Windows 10 try to run the LLDP script constantly and it fills the logs on the switches. If we disable the Microsoft LLDP Protocol Driver on the Surface it stops.

Is there a way to have the switch not run the script when the Surface connects? We have advised our helpdesk to disable this but that doesn't always happen.

What LLDP scripts are you using? Is this a UPM profile triggered on a device-detect event?

Can you post a snippet of the log, as well as the UPM config if relevant?

Yes, we are using UPM profile device-detect to detect the phones when they are plugged in. Here is the script

************Profile Contents Begin************

#@Description Voice VLAN name
set var voicevlan XXXX
if (!$match($EVENT.NAME,DEVICE-DETECT)) then
create log entry ***Starting_LLDP_Config***
endif
#Link Layer Discovery Protocol-Media Endpoint Discover
create log entry ***Config_LLDP_Parameters***
configure lldp port $EVENT.USER_PORT advertise vendor-specific med capabilities
configure lldp port $EVENT.USER_PORT advertise vendor-specific dot1 vlan-name vlan $voicevlan
configure lldp port $EVENT.USER_PORT advertise vendor-specific med policy application voice vlan $voicevlan dscp 46
create log entry ***Config_LLDP_Parameters_Complete***
create log entry ***End_LLDP_Generic_Config***

************Profile Contents Ends*************

Profile State: Enabled
Profile Maximum Execution Time: 30
Events and ports configured on the profile:

You might check to see if the OUI is unique for the Mitel phones and only do the LLDP portion of the scripts if the MAC of the device detected has that OUI. This would at least cut out the System.userComment log entries.

You can check the vendor name. Assuming the variable is set to MITEL, you could then add a condition for it, something like:

if (!$match($EVENT.DEVICE_MANUFACTURER_NAME,MITEL)) then

just verify how is set that variable.

Thank you for the input, I will see what I can do.

I have been working on this and still cannot get the Surface to stop running the script. I am not that good with scripting so I am having a hard time. Would someone be able to help? I am getting lost on how to end the script if the conditions don't match.

create upm profile detect-voip-XXXX

#@Description “Voice VLAN name”

if(!$match($EVENT.NAME,DEVICE-DETECT)) and

if(!$match($EVENT.DEVICE_MANUFACTURER_NAME,MITEL)) then

set var voicevlan XXXX

create log entry ***Starting_LLDP_Config***

endif

#Link Layer Discovery Protocol-Media Endpoint Discover

create log entry ***Config_LLDP_Parameters***

configure lldp port $EVENT.USER_PORT advertise vendor-specific med capabilities

configure lldp port $EVENT.USER_PORT advertise vendor-specific dot1 vlan-name vlan $voicevlan

configure lldp port $EVENT.USER_PORT advertise vendor-specific med policy application voice vlan $voicevlan dscp 46

create log entry ***Completed_LLDP_Parameters***

.

config upm event device-detect profile detect-voip-XXXX ports 1-5

What is the purpose of the endif in the middle of the script? This script was wrote by a vendor years ago.

Thanks!

Try this:

#@Description “Voice VLAN name”

if (!$match($EVENT.NAME,DEVICE-DETECT)) && if (!$match($EVENT.DEVICE_MANUFACTURER_NAME,MITEL)) then
set var voicevlan XXXX
create log entry ***Starting_LLDP_Config***

#Link Layer Discovery Protocol-Media Endpoint Discover
create log entry ***Config_LLDP_Parameters***
configure lldp port $EVENT.USER_PORT advertise vendor-specific med capabilities
configure lldp port $EVENT.USER_PORT advertise vendor-specific dot1 vlan-name vlan $voicevlan
configure lldp port $EVENT.USER_PORT advertise vendor-specific med policy application voice vlan $voicevlan dscp 46
create log entry ***Completed_LLDP_Parameters***
endif

.

Assuming the variable is, indeed, MITEL. You should check that.

Thank you for the help, I will check that variable and try the changes you suggested.
