Per Port Location Configuration

---

The Per Port Location Configuration feature provides a mechanism for configuring the location attributes for specific ports. This feature provides the ability to configure Link Layer Discovery Protocol (LLDP) location information per port, overriding the global switch configuration. Thus, devices attached remotely to the switch can be given specific location information.

Information About Per Port Location Configuration

• IEEE 802.1ab LLDP

IEEE 802.1ab LLDP

IEEE 802.1ab Link Layer Discovery Protocol (LLDP) is an optional link layer protocol for network topology discovery in multivendor networks. Discovery information includes device identifiers, port identifiers, versions, and other details. As a protocol that aids network management, LLDP provides accurate network mapping, inventory data, and network troubleshooting information.

LLDP is unidirectional, operating only in an advertising mode. LLDP does not solicit information or monitor state changes between LLDP nodes. LLDP periodically sends advertisements to a constrained multicast address. Devices supporting LLDP can send information about themselves while they receive and record information about their neighbors. Additionally, devices can choose to turn off the send or receive functions independently. Advertisements are sent out and received on every active and enabled interface, allowing any device in a network to learn about all devices to which it is connected. Applications that use this information include network topology discovery, inventory management, emergency services, VLAN assignment, and inline power supply.

Note	LLDP and Cisco Discovery Protocol can operate on the same interface.

The figure below shows a high-level view of LLDP operating in a network node.

When you configure LLDP or Cisco Discovery Protocol location information on a per-port basis, remote devices can send Cisco medianet location information to the switch. For more information, see the Using Cisco Discovery Protocol module.

How to Configure Per Port Location Configuration

• Configuring Per Port Location Configuration

Configuring Per Port Location Configuration

SUMMARY STEPS

1.    enable


2.    configure terminal


3.    interface type number


4.    location {additional-location-information word | civic-location-id id [port-location]| elin-location-id id}


5.    end

DETAILED STEPS

	Command or Action	Purpose
Step 1	enable Example: Device> enable	Enables privileged EXEC mode. Enter your password if prompted.
Step 2	configure terminal Example: Device# configure terminal	Enters global configuration mode.
Step 3	interface type number Example: Device(config)# interface fastethernet 0	Specifies the interface on which you are configuring the location information, and enters interface configuration mode.
Step 4	location {additional-location-information word | civic-location-id id [port-location]| elin-location-id id} Example: Device(config-if)# location civic-location-id 1 port-location	Specifies location information for an interface, and enters civic location port configuration mode. You can configure port-specific information in civic location port configuration mode.
Step 5	end Example: Device(config-if-port)# end	Returns to privileged EXEC mode.
