Configuring the Receive Window Size
You can configure the L2TP receive window size (RWS) for an L2TP tunnel. L2TP
uses the RWS to implement a sliding window mechanism for the transmission of
control messages.
When you configure the RWS, you specify the number of packets that the L2TP peer
can transmit without receiving an acknowledgment from the router. If the RWS is
not configured, the router determines the RWS and uses this value for all new tunnels
on both the LAC and the LNS.
You can configure the L2TP RWS in the following ways:
■
Configure the systemwide default RWS setting for a tunnel on both the LAC and
the LNS by using the
l2tp tunnel default-receive-window
command (in global
Configuration mode).
■
Configure the RWS for a tunnel on the LAC by using either the
receive-window
command (in Domain Map Tunnel Configuration mode) or by including the
L2tp-Recv-Window-Size RADIUS attribute (VSA 26-54) in RADIUS Access-Accept
messages.
■
Configure the RWS for all tunnels that use a particular host profile on the LNS
by using the
receive-window
command (in L2TP Destination Profile Host
Configuration mode).

Configuring the Default Receive Window Size
Use the
l2tp tunnel default-receive-window
command to configure the default L2TP
RWS for a tunnel on both the LAC and the LNS. The default L2TP RWS is the number
of packets that the L2TP peer can transmit without receiving an acknowledgment
from the router. The only supported value is 4.
To configure the default RWS setting:
1.
From Global Configuration mode, set the L2TP default RWS. The only value
supported for the default RWS is 4.
host1(config)#
l2tp tunnel default-receive-window 4
The router uses this RWS value for all new tunnels on both the LAC and the LNS.
The new command has no effect on previously configured tunnels.
2.
(Optional) Use the
show l2tp
command to verify the default RWS configuration.
host1#
show l2tp
Configuration
L2TP administrative state is enabled
Dynamic interface destruct timeout is 600 seconds
Data packet checksums are disabled
