Site Network Map; Logical Connections; Device Configuration Information; Other Important Data About Your Network - Avaya 8800 Troubleshooting Manual

Troubleshooting planning fundamentals

Site network map

A site network map identifies where each device is physically located on your site. It helps
locate the users and applications that are affected by a problem. You can use the map to
systematically search each part of your network for problems.

Logical connections

The Avaya Ethernet Routing Switch 8800/8600 supports virtual LANs (VLAN). With VLANs,
you must know how your devices are connected both logically and physically.

Device configuration information

Maintain online and paper copies of your device configuration information. Ensure that all
online data is stored with the regular data backup for your site. If your site does not have a
backup system, copy the information onto a backup disk (such as a CD or zip disk) and store
the backup disk in an off-site location.
You can use FTP and TFTP to store configuration files on a remote server.

Other important data about your network

For a complete picture of your network, have the following information available:
• all passwords
Store passwords in a safe place. Keep records of you previous passwords in case you
must restore a device to a previous software version and need to use the old password
that was valid for that version.
• device inventory
Maintain a device inventory which lists all devices and relevant information for your
network. The inventory lets you easily see the device type, IP address, ports, MAC
addresses, and attached devices.
• MAC address-to-port number list
If your hubs or switches are not managed, you must keep a list of the MAC addresses
that correlate to the ports on your hubs and switches.
• change control
