66 CHAPTER 7: BACKING UP AND RESTORING SOFTWARE
Restoring Software
from a Backup
If your bridge/router fails, you can restore software from a backup on the NMS. If
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:
1 Attach a console to the Console port on the bridge/router.
2 Log on as root and press the Return key.
The password prompt is displayed.
3 At the password prompt, press the Return key.
The network manager prompt (Enterprise OS #) is displayed.
4 Set 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.
5 Enable IP routing by entering:
SETDefault -IP CONTrol = ROute
6 Enable a routing protocol. For example, enable OSPF using:
SETDefault !<port> -OSPF CONTrol = Enable
7 Ensure 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.
1 The 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
