You can configure an E Series LNS to convey PPP-related disconnect cause information
to its L2TP peer. Enabling an LNS to send disconnect cause information to an LAC is
particularly useful in an environment where the LAC initiates tunnels without a client's
request, knowledge, or approval. In this type of environment, all PPP signaling for the
tunnel session takes place between the LNS and the client, without active participation
of the LAC. As a result, the LAC is not aware of the reason that a session has disconnected.
NOTE: An E Series LAC does not send PPP Disconnect Case Code AVPs to
an LNS. In the event that a third-party LAC does send the AVP to an E Series
LNS, the LNS discards the AVP.

You use the l2tp disconnect-cause command to specify that the LNS include the PPP
Disconnect Cause Code AVP in all L2TP Call-Disconnect-Notify (CDN) messages that
it sends to the LAC. For example, this feature enables the LAC to obtain information
about the cause of a session disconnection,
To enable disconnect cause generation chassis-wide on the LNS:
host1(config)#l2tp disconnect-cause
NOTE: Sessions for which the AVP generation is enabled by the
host-profile-specific disconnect-cause command continue to generate
the AVP.
You use the disconnect-cause command in L2TP Destination Profile Host Configuration
mode to specify that the E Series LNS generate PPP Disconnect Cause Code AVPs. This
command pertains only to L2TP sessions to which the L2TP destination host profile
applies. The AVP is included in all L2TP CDN messages that the LNS sends to an LAC for
covered sessions.
