Allied Telesis AT-WR4500 Monitoring L2TP Client, Command name /interface l2tp-client monitor

AT-WR4500 Series - IEEE 802.11abgh Outdoor Wireless Routers	163
RouterOS v3 Configuration and User Guide

mrru (integer: 512..65535; default: disabled) - maximum packet size that can be received on the link. If a packet is bigger than tunnel MTU, it will be split into multiple packets, allowing full size IP or Ethernet packets to be sent over the tunnel

disabled - disable MRRU on this link

name (name; default: l2tp-outN) - interface name for reference

password (text; default: "") - user password to use when logging to the remote server

profile (name; default: default) - profile to use when connecting to the remote server user (text) - user name to use when logging on to the remote server

￿

Specifying MRRU means enabling MP (Multilink PPP) over single link. This protocol is used to split big packets into smaller ones. Under Windows it can be enabled in Networking tag, Settings button, "Negotiate multi-link for single link connections". Their MRRU is hardcoded to 1614. This setting is usefull to overcome PathMTU discovery failures. The MP should be enabled on both peers.

Example

To set up L2TP client named test2 using username john with password john to connect to the

10.1.1.12L2TP server and use it as the default gateway:

[admin@AT-WR4562] interface l2tp-client> add name=test2 connect-to=10.1.1.12 \ \... user=john add-default-route=yes password=john

[admin@AT-WR4562] interface l2tp-client> print Flags: X - disabled, R - running

0 X name="test2" mtu=1460 mru=1460 connect-to=10.1.1.12 user="john" password="john" profile=default add-default-route=yes allow=pap,chap,mschap1,mschap2

[admin@AT-WR4562] interface l2tp-client> enable 0

8.5.3 Monitoring L2TP Client

Command name: /interface l2tp-client monitor

Property Description

encoding (text) - encryption and encoding (if asymmetric, separated with '/') being used n this connection idle-time(read-only: time) - time since the last packet has been transmitted over this link

mru (read-only: integer) - effective MRU of the link

mtu (read-only: integer) - effective MTU of the link status (text) - status of the client

dialing - attempting to make a connection

verifying password... - connection has been established to the server, password verification in progress connected - self-explanatory

terminated - interface is not enabled or the other side will not establish a connection uptime (time) - connection time displayed in days, hours, minutes and seconds

Example

Example of an established connection

[admin@AT-WR4562] interface l2tp-client> monitor test2 status: "connected"

uptime: 6h44m9s idle-time: 6h44m9s encoding: "MPPE128 stateless"

mtu: 1460

mru: 1460
