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
7 Copy the upgraded software to the bridge/router using:
bcmsysupgrade -s:to_nb -m -new_hw <device>
8 Accept your upgrade using:
bcmsysupgrade -s:accept -m -new_hw <device>
The bridge/router reboots.
9 Verify 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 bridge/router. 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.
■ Testing typical device connections on terminals, printers, or hosts.
■ Testing the connectivity with specific NETBuilder bridge/routers.
■ Custom checks based on applications and typical network use.
For instance, you can check normal operation over the network and perform
file transfers, as well as run traces on specific routes or check routing tables.
10 If you determine that the new software does not meet your requirements, you can
reject the upgrade, and revert to the software version you were running before
the upgrade, by using the bcmrestore utility.
To reject your upgrade, use:
bcmrestore -new_hw <device>
11 NETBuilder II only — If the upgrade is successful, and the NETBuilder II
bridge/router has a multiport HSS module or an MP module, upgrade the
firmware for all these modules using:
bcmsysupgrade -s:upgrade_io_fw -m <device>
The bridge/router reboots after the firmware is upgraded.
If the Bridge/Router or Switch Does Not Boot
If a failure causes the bridge/router not to boot, or if the bridge/router or switch is
inaccessible using Telnet, you must configure the bridge/router or switch at the
local console to reestablish IP connectivity. After connectivity is reestablished, you
can use the bcmrestore utility to return the bridge/router or switch to a
preupgrade state. See Chapter 7 for connectivity and recovery procedures.
