48CHAPTER 5: UPGRADING A BRIDGE/ROUTER USING THE COMMAND-LINE UTILITIES

CAUTION: When upgrading to a package containing encryption, you must specify the -EncyrptionLicenseRead option flag. If you attempt to upgrade to an encrypted package and you have not specified the -EncryptionLicenseRead option, the upgrade will fail.

The bcmsysupgrade utility only backs up the files in the primary boot source. To archive both the primary and secondary boot sources, use bcmbackup instead of bcmsysupgrade. See “bcmbackup” on page 73 for more information.

2Update your configuration files using:

bcmsysupgrade -s:update -m -new_hw <device>

3Upgrade your hardware.

4Attach a console to the Console port on the bridge/router.

5Set up IP routing by following these steps:

a Log on to the bridge/router as root and press the Return key. The password prompt is displayed.

b At the password prompt, press the Return key.

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

cSet up an IP address and subnet mask using:

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

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 routing protocol. For example, enable RIP by using:

SETDefault !<port> -RIPIP CONTrol = (TAlk, LIsten)

fCheck your configuration by verifying that the bridge/router is accessible by using the following at the network management station:

PING <IP address>

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

6Set 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 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
