Establishing a Modem (PPP) Connection
Point-to-Point Protocol (PPP) provides a Layer 2 method for transporting multi-protocol
datagrams over modem links.

Connecting a Modem to the Console Port

Before you can establish a PPP connection with a modem can be established, you need to
configure the following:
●C360 IP address: refer to Assigning C360 IP Stack Address for further information.
●net-mask
●PPP parameters that are compatible with the modem's PPP parameters.
1. Connect a terminal to the console port of the C360 switch as described in Connecting a
Terminal to the C360 Serial port.
2. When you are prompted for a Login Name, enter the default name root.
3. When you are prompted for a password, enter the password root. You are now in
Supervisor Level.
4. At the prompt, type:
set interface ppp <ip_addr> <net-mask>
with an IP address and netmask to be used by the C360 to connect via its PPP interface.
Note:
Note: The PPP interface configured with the set interface ppp command must be
on a different subnet from the stack inband interface.
5. Set the baud rate, ppp authentication, and ppp time out required to match your modem.
These commands are described in the Reference Guide for the Avaya C360 Converged
Stackable Switch, 10-300506.
6. At the prompt, type:
set interface ppp enable
●The CLI responds with the following:
Entering the Modem mode within 60 seconds...
Please check that the proprietary modem cable is plugged into the
console port
7. Use the DB-25 to RJ-45 connector provided in the accessory kit to plug the console cable to
the modem's DB-25 connector. Plug the other end of the cable RJ-45 connector to the
C360 console's RJ-45 port.
8. The C360 enters modem mode.
