View source for LLDP

Warning: Do not follow this guide unless you know for certain you need LLDP. Incorrectly implementing this protocol MAY lead to undesired network functionality.

This guide applies to Cisco switches, and the screenshots are specifically from a SG300 28 port switch. Some options may be named differently, or not exist at all on other brands of network equipment.



===In the switch:===



LLDP Status: Enabled

TLV Advertise Interval: 60

===In the PBX===
Ensure all phones have LLDP enabled. &nbsp;You can set this on each phone individually in the menu under Settings=>Advanced=>Network=>LLDP, but we would recommend following the instructions listed at [http://wiki.ipitomy.com/wiki/HD_Phone_FAQ#How_do_I_Enabled_LLDP_Globally_for_the_Phones http://wiki.ipitomy.com/wiki/HD_Phone_FAQ#How_do_I_Enabled_LLDP_Globally_for_the_Phones] to set LLDP globally if you need it for all phones.
