TIP: The RWS setting must be the same for all users of the same tunnel.
If you modify the RWS setting for an existing tunnel, subsequent tunnel users
might be not be able to log in if their RWS setting conflicts with the new RWS
setting for the tunnel.
To configure the RWS for a tunnel on the LAC:
Access Domain Map Tunnel Configuration mode as described in "Mapping a User
1.
Domain Name to an L2TP Tunnel Overview" on page 358 . For example:
host1(config)#aaa domain-map fms.com
host1(config-domain-map)#router-name westford
host1(config-domain-map)#tunnel 3
host1(config-domain-map-tunnel)#
From Domain Map Tunnel Configuration mode, set the tunnel RWS. The only value
2.
supported for the tunnel RWS is 4, and it must be the same for all users of the same
tunnel.
host1(config-domain-map-tunnel)#receive-window 4
(Optional) Use the show aaa domain-map command to verify the RWS configuration.
3.
host1#show aaa domain-map
Domain: fms.com; router-name: westford; ipv6-router-name: default

You can also configure the RWS for a tunnel on the LAC by including the
L2tp-Recv-Window-Size RADIUS attribute (VSA 26-54) in RADIUS Access-Accept
messages. For more information about RADIUS Access-Accept messages, see "Configuring
RADIUS Attributes" on page 167. For more information about the L2tp-Recv-Window-Size
attribute, see "RADIUS IETF Attributes" on page 255.
Use the receive-window command to configure the L2TP RWS for a tunnel on the LNS.
Use the no version of the command to revert to the systemwide RWS setting configured
with the l2tp tunnel default-receive-window command.
To configure the RWS for a tunnel on the LNS:
Access L2TP Destination Profile Host Configuration mode. For example:
1.
host1(config)#virtual-router fms02
