24 Upgrading SNMP
217316-A Rev 00
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 run-time
configuration.
3 After the reboot, 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 from a
hidden file to another 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 NOT be found in configuration files. If you
choose to swap the existing CPU Module with a new CPU Module, you
must copy all hidden files to the new module, in addition to the regular
files, in order for the SNMP strings to work correctly.
— Default strings such as “public” and “private” are translated as is.
— The default string “secret” for rwa is no longer applicable in Release 3.7.
— All “l1”, “l2”, “l3”, and “rwa” SNMP strings will now be “rw.”

High Availability
The standard procedure for HA upgrade needs to be followed. Refer to Upgrading
to Passport 8000 Series Switch Software Release 3.7.6 (318843-A) for more
information. The upgrade process creates identical hidden files on both CPUs.
Failover between CPUs should appear hitless with respect to SNMP connectivity.
