General access guidelines

The following considerations apply to the access procedures covered in this section.

• If a firewall is in place, you must access any IP devices such as the Layer 2 Switching Processor, MGP, or Media Server from within the firewall boundary, or the firewall must grant the required access.
• Most corporate networks have one or more domain name service (DNS) servers that associate an IP address with a device's name. You can only access an IP device by name if the DNS server has been administered and is accessible for name resolution from the interface you are using. For example, direct connections from a laptop to the Services interface on the S8300 Media Server must use the server's default IP address. DNS is unavailable for this access method, since the user is not on the network.
• Login service levels control access to the S8300 Media Server. These levels are specified through Avaya Site Administration or SAT. On the Login Administration screen, under Login Being Administered, the following service levels can be specified:
• super-user. Logins assigned to this service level receive full access to the Media Server web interface. All screens are available.
• non-super-user. Logins assigned to this service level receive a restricted level of access to the web interface. Only a few display-only screens are accessible.
• remote. Logins assigned to this service level can use a PPP dial-up connection.
