Chapter 3: Accessing the Avaya
You can access the Avaya G250/G350 Media Gateway using the CLI, the IW, the GIW, the PIM,
and the Avaya Communication Manager. You can manage login permissions by using and
configuring usernames and passwords, and by configuring the G250/G350 to use SSH, SCP,
RADIUS authentication, and the 802.1x protocol. There are special security features that
enable and disable the recovery password, establish incoming and outgoing telnet connections,
and configure SYN cookies for preventing SYN attacks.

Accessing the CLI

The CLI is a textual command prompt interface that you can use to configure the Avaya
G250/G350 Media Gateway and media modules. You can access the CLI with any of the
following:
Telnet through the network
●
A console device
●
Telnet through dialup:
●
- Telnet through a serial modem
- Telnet through a USB modem
- Telnet through a USB modem via the S8300
If the G250/G350 is under service contract with Avaya Services, remote service providers can
connect remotely to service the G250/G350 with telnet and SSH sessions. You can configure
the G250/G350 to authenticate remote service logins using Access Security Gateway (ASG)
authentication instead of password authentication, for higher security.

Logging into the CLI

Log in to the CLI with a username and password that your system administrator provides. Use
RADIUS authentication if your network has a RADIUS server. For more information, see
