22 Upgrading SNMP
217316-A Rev 00
• When upgrading from Release 3.5 to Release 3.7, read-only (ro) user is
mapped into ReadView with read-only access. (Q00889700)
• After performing the upgrade, Nortel Networks strongly recommends that
you set a password for the initial USM.
Upgrading SNMP from Release 3.3 to Release 3.7
In the Passport 8000 Series Switch Release 3.3, you set SNMP community strings
by using the following command (this command is now obsolete):
config sys set snmp community rwa <commstring>
After you save the configuration, this command appears in the configuration file.
This behavior has changed in Release 3.7. The upgrade procedure follows.
Non-High Availability
1 Change and save the bootconfig options to the appropriate Release 3.7 image
by entering the following commands:
config bootconfig primary choice /flash/p80a3760.img
save bootconfig
2 Boot up the chassis and upgrade the Boot Monitor by entering the following
command:
boot /flash/p80b3760.img
The SNMP upgrade procedure loads the SNMP configuration into the
run-time configuration.
3 Save the configuration by entering the following command:
save config file /flash/config1.cfg
When you enter this command, the following activities occur:
— Configurations related to SNMP trap receivers are automatically mapped
into Release 3.7-compatible commands in config1.cfg.
— Configurations related to SNMP community strings are ported to a hidden
and encrypted file. This file must exist for you to access the chassis using
SNMP. From this point forward, information regarding SNMP
community strings will be stored ONLY in this hidden file and WILL
