2. SNMP Upgrade Considerations

Please note the following when upgrading software on the ERS8600.

Starting in software release 3.7 and continued to software release 4.1.x, the CLI command save config creates a hidden and encrypted file that contains the SNMP community table information. For security purposes, the save config command also removes reference to the existing SNMP community strings in the newly created configuration file. Please note that if you only have one CPU, and if you swap the CPU, you must backup all hidden files or else all the password and SNMP references will be lost. If you do not backup the hidden files, you must reconfigure your trap receivers and community strings every time you change the CPU.

The commands to change the SNMP Community strings and trap receivers in software release

3.3have changed in software releases 3.5, 3.7, 4.0, and 4.1.x. However, even though software releases 3.5, 3.7, 4.0, and 4.1.x use the same commands, in software release 3.7 and 4.1.x only, the SNMP community strings and trap receivers are stored in a hidden and encrypted file and are not found in the configuration file. This is similar with software releases 3.5 and 4.0; however the files are stored in a hidden non-encrypted file. Upgrades from 3.7 to 4.1.x, all files are translated as-is. Please see section 3.3.3 for more details.

2.1 Hidden File Details

Backup the following configuration files to either via FTP, a TFTP server or a PCMCIA card:

•shadov.txt

•snmp_usm.txt

•snmp_comm.txt

•password.txt
