Upgrading SNMP 23
Release Notes for the Passport 8600 Release 3.7.6
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— The default string “secret” for rwa is no longer applicable in Release 3.7.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
Follow the standard procedure for the HA upgrade. 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.
Upgrading SNMP from Release 3.5 to Release 3.7
In the Passport 8000 Series Switch Release 3.5, 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 will NOT appear in the
configuration file, as community strings are stored in a hidden file instead. This
behavior has changed in Release 3.7. The upgrade procedure is detailed below.
Non-High Availability
1 In CLI mode, before performing the upgrade, 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
