Configuring PPP and MLPPP
config ppp authentication [off | chap | pap | chap-pap] [ports
<portlist> | multilink <groupname>]

PPP Link Username

When the local end of a link initiates a PPP connection, the local end must send the
appropriate authentication information. For PAP it sends the username and password,
for CHAP it sends the username and must respond correctly to the challenge, and for
no authentication it sends nothing. To configure the username and password used to
initiate the link, use the following command:
config ppp user <username> {encrypted} <password> [ports <portlist> |
multilink <groupname>]
The encrypted keyword is used to hide the password when the switch configuration is
displayed; it does not control whether the password is encrypted across the link during
authentication.

PPP User Accounts

When the remote end initiates the link, the local end must verify the authentication
information. The local end maintains a list of authorized user accounts and passwords.
To add a user to the list, use the following command:
create account pppuser <name> {encrypted} {<password>}

Encapsulation

The packets passed over the PPP/MLPPP link can use either bridged or routed
encapsulation. You would use bridged packets if you plan to have VLANs span the
link. You would use routed packets if the link connects two different routed networks
or separate VLANs.
Using bridged packets allows the VLAN tags to be carried across the PPP/MLPPP link.
Bridged packets are transported using the PPP Bridging Control Protocol (BCP),
described in RFC 2878. When the encapsulation is set to BCP, 802.1Q and 802.1p
information is preserved and transported across the link. On a WAN module, a VLAN
may only contain one BCP encapsulated link, but you may have multiple VLANs span
the link.
