Pinging Layer 2 Circuits

Enter the ping mpls l2circuit command with the following syntax. Table 120 on page 236 describes the ping mpls l2circuit command options.

user@host> ping mpls l2circuit (interface interface-namevirtual-circuit neighbor

prefix-name virtual-circuit-id) <exp forwarding-class> <count number> <source source-address> <detail>

To quit the ping mpls l2circuit command, press Ctrl-C.

Alternatively, you can use the J-Web interface. (See “Checking MPLS Connections from the J-Web Interface” on page 219.)

Table 120: CLI ping mpls l2circuit Command Options

Option	Description
l2circuit interface	Sends ping requests out the specified interface configured for the Layer 2 circuit on the outbound
interface-name	PE router.
l2circuit virtual-circuit	Pings on a combination of the IPv4 prefix and the virtual circuit identifier on the outbound PE
neighbor prefix-name	router, testing the integrity of the Layer 2 circuit between the inbound and outbound PE routers.
virtual-circuit-id
exp forwarding-class	(Optional) Specifies the value of the forwarding class to be used in the MPLS ping packets.
countnumber	(Optional) Limits the number of ping requests to send. Specify a count from 0 through 1,000,000.

detail	(Optional) Displays detailed output about the echo requests sent and received. Detailed output
	includes the MPLS labels used for each request and the return codes for each request.

Following is sample output from a ping mpls l2circuit command:
