Enabling RADIUS Accounting for Disconnect Cause

Displaying Disconnect Cause Statistics

Configuring the Receive Window Size

NOTE: This command is used only for dial-in sessions; use the l2tp
disconnect-cause command in Global Configuration mode to generate PPP
Disconnect Cause Code AVPs for dial-out sessions.
To enable disconnect cause generation for all tunnels that use a particular host profile
on the LNS:
host1(config-l2tp-dest-profile-host)#disconnect-cause
You use the radius include l2tp-ppp-disconnect-cause acct-stop enable command to
specify that the Disconnect-Cause RADIUS attribute (VSA 26-51) is generated and
included in RADIUS acct-stop and acct-tunnel-link-stop records. RADIUS VSA 26-51 is
not included in the accounting records by default.
At the LAC, this accounting reports remotely generated disconnect cause information
received from the LNS. At the LNS, the accounting reports locally generated disconnect
cause information.
To enable disconnect cause accounting:
host1(config)#radius include l2tp-ppp-disconnect-cause acct-stop enable
You can display chassis-wide summary statistics for all disconnect cause information
received by the LAC, sorted by code number.
To display summary statistics for disconnect cause information:
host1(config)#show l2tp received-disconnect-cause-summary
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
