66CHAPTER 7: BACKING UP AND RESTORING SOFTWARE

Restoring Software If your bridge/router fails, you can restore software from a backup on the NMS. If

from a Backup your hardware fails or you lose IP and SNMP configuration, you must first reconfigure IP and SNMP on the bridge/router. If you still have connectivity, go to “Restoring the Software Using Upgrade Link” on page 68 or “Restoring the Software Using the Command-Line”on page 69.

Configuring IP Routing If the bridge/router failure interrupted IP connectivity, you must set up IP routing before restoring software.

To set up IP routing, follow these steps:

1Attach a console to the Console port on the bridge/router.

2Log on as root and press the Return key. The password prompt is displayed.

3At the password prompt, press the Return key.

The network manager prompt (Enterprise OS #) is displayed.

4Set up an IP address and subnet mask using:

SETDefault !<port> -IP NETaddr = <IP address> [<subnet mask>]

For more information on IP configuration, see Using Enterprise OS Software.

5Enable IP routing by entering:

SETDefault -IP CONTrol = ROute

6Enable a routing protocol. For example, enable OSPF using:

SETDefault !<port> -OSPF CONTrol = Enable

7Ensure your configuration by verifying that the bridge/router is accessible from the NMS using:

PING <IP address>

Where <IP address> is the IP address of the bridge/router.

Configuring SNMP This chapter does not describe in detail how to set up the SNMP Service. See Using Enterprise OS Software and Reference for Enterprise OS Software for more information.

To enable SNMP read/write access, you need to modify two parameters in the

SNMP service: Community Manager and Manager.

1The Community Manager parameter modifies the list of communities. For information on how to use the COMmunity parameter, see Using Enterprise OS Software and Reference for Enterprise OS Software.

By default all bridge/router configuration files are accessible to an SNMP-based manager with read privileges. To change SNMP access to configuration files to read/write for a network management station with a community named “public,” enter:

ADD -SNMP COMmunity “public” RW
