L2TP SET WINDOW

Enhances trafÞc performance in a tunneling environment. The commandÕs options affect the way incoming

payload packets are processed. The router is conÞgured with the following default options: sequencing, required,

and size 10.

REMOTE SETL2TPCLIENT

With this command, this remote is the path to the L2TP client and accepts tunnel calls. Use this command if your

router acts as an LNS. You must also specify PPP authentication and IP routes for this remote.

REMOTE SETLNS

With this command, this remote is the path to the LNS, and it will forward the incoming call (which matches this

remote entry) through the tunnel named <TunnelName> if your router is the client.

sequencing Sequence numbers are placed in the L2TP payload packets. With this option, one end instructs

the other end to send sequence packets. No acknowlegments are issued for received packets.

pacing Sequence numbers are placed in the L2TP payload packets. When a session is created, the

router speciÞes a window size. Acknowledgments for received packets are issued.

nosequencing No sequence numbers are placed in the L2TP payload packets carrying the PPP packets. If the

remote end carries out sequencing or pacing, the router can still send and receive sequenced

packets.

optional Allows dynamic switching of a session from pacing or sequencing to nosequencing.

required Disables dynamic switching from pacing or sequencing to nosequencing.

size Controls the size of the receive window for receiving packets for sequencing or pacing, when a

session is created. Size can be 0 for packet sequencing. Must be a non-zero value for window

pacing. Size must be less than or equal to 30.

TunnelName Name of the tunnel (character string). This name is case-sensitive.

Example:

l2tp set window sequencing PacingAtWork

remote setl2tpclient <TunnelName><remoteName>

TunnelName Name of the tunnel (character string) associated with the remote LAC. The name is case-

sensitive.

remoteName Name of the remote entry (character string). The name is case sensitive.
