46CHAPTER 5: UPGRADING A BRIDGE/ROUTER USING THE COMMAND-LINE UTILITIES

Where <port> is the port through which the bridge/router can be accessed by the NMS.

dEnable IP routing by entering:

SETDefault -IP CONTrol = ROute

eEnable a route discovery protocol. For example, enable OSPF by using:

SETDefault !<port> -OSPF CONTrol = Enable

fCheck your configuration by pinging the bridge/router from the NMS:

ping <IP address>

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

7Set up SNMP.

This guide 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 and MANager.

aThe COMmunity 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 for a community named public, enter:

ADD -SNMP COMmunity "public" RW

bWith the MANager parameter, create a new manager with read/write access to the bridge/router. For security reasons, limit the number of network management stations by entering the IP address of the network management station that will have access. For example, enter:

ADD -SNMP MANager “sysadm” 129.213.224.1

8Copy the upgraded software to the bridge/router using:

bcmsysupgrade -s:to_nb -new_hw <device>

9Test your new software using:

bcmsysupgrade -s:test_boot -new_hw <device>

The bridge/router is rebooted, and the utilities confirm IP connectivity and that the expected version of software is running.

10Verify that your upgrade completed successfully.

To verify that the software is working properly, you can perform a set of operational integrity checks on the newly upgraded device. These may include:

■Some standard checks based on services active.

A basic service verification test can Ping to specific IP addresses.

■Connectivity checks based on network topology. Examples of a connectivity verification include:

■Checking the connectivity between devices on different networks, through designated bridge/routers.
