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-name | virtual-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.)
