The output of the
show status
command shows:
• which LNS is active at the moment – primary or backup
• tunnel uptime
• number of transmitted and received packets and bytes:
—first line shows total number of packets,
—second line shows the number of MAC broadcasts
—third line shows number of MAC multicasts
• number of packets fragmented/reassembled (due to MTU size)
Starting and Stopping
Layer 2 Tunneling
/protocol/te-<eng>/set engine admin-state {enabled|disabled}
This command starts and stops tunneling operation. Use
enabled
to begin
tunneling operation. Use
disabled
to stop all tunnel forwarding.
Configuring Layer 2
Tunnels
/protocol/te-<eng>/set tunnel <index> ip <peer_IP_addr>
name <stn_name>
[backup-ip <backup_IP_addr> [backup-name <backup_name>]]
[switch {non-revertive | revertive}]
/protocol/te-<eng>/delete tunnel {all|<index>}
The
set tunnel
command creates a new tunnel to be terminated at the specified
peer IP address, which is usually the network central router. You can create up
to five tunnels to the same peer or to different peers. Each tunnel carries just
one L2TP session.
The <index> parameter is used for easy reference when using other
commands. It can be displayed with the
/protocol/te-<eng>/show config
command.
The <stn_name> parameter can be any series of 18 alphanumeric ASCII
characters. L2TP protocol provides the <stn_name> parameter to the other
end point so it can identify different tunnels coming from the same IP address
or create logical group of nodes with the same name and different IP addresses.
