5.10.7 Checking Connectivity of the VLL Network

The VLL connectivity can be checked through the ping or tracert command.
Prerequisite
Before using the ping or tracert command to check connectivity of a VLL network, you need
to ensure that the VLL network is correctly configured.
The channel types supported by the VLL network in Martini or Kompella mode are listed in the
"Procedure" part.
By default, VCCV in Label Alert mode is enabled. Before using the control word channel, you
need to run the control-word command to enable the control word function. After that, VCCV
in control word channel mode is enabled.
When locating the fault on the VLL network in Martini mode, you can use either VCCV in
control word channel mode or VCCV in normal mode.
