Cisco Cisco IPS 4255 Sensor 릴리즈 노트

You cannot use the downgrade command to downgrade from 6.0(1)E1 to 5.1. You can only 
downgrade from new service packs and signature updates to the previous version of service 
pack or signature update. 

Upgraded the IDS 4215 BIOS to the most recent version.

If you are using SNMP set and/or get features, you must configure the read-only-community and 
read-write-community parameters before upgrading to IPS 6.0(1)E1. 

In IPS 5.x, the read-only-community was set to public by default, and the read-write-community 
was set to private by default. In IPS 6.0(1)E1 these two options do not have default values. If you 
were not using SNMP gets and sets with IPS 5.x (for example, enable-set-get was set to false), there 
is no problem upgrading to IPS 6.0(1)E1. If you were using SNMP gets and sets with IPS 5.x (for 
example, enable-set-get was set to true), you must configure the read-only-community and 
read-write-community parameters to specific values or the IPS 6.0(1)E1 upgrade fails. You receive 
the following error message:

Error: execUpgradeSoftware : Notification Application “enable-set-get” value set to 

true, but “read-only-community” and/or “read-write-community” are set to null. Upgrade 

may not continue with null values in these fields.

We recommend copying the current configuration file to a remote server before upgrading.

Use the copy [/erase] source_url destination_url keyword command to copy the configuration file to a 
remote server. You can then restore the current configuration from the remote server. You are prompted 
to back up the current configuration first.

The following options apply:

/erase—Erases the destination file before copying. 

This keyword only applies to the current-config; the backup-config is always overwritten. If this 
keyword is specified for destination current-config, the source configuration is applied to the system 
default configuration. If it is not specified for the destination current-config, the source 
configuration is merged with the current-config.

source_url—The location of the source file to be copied. It can be a URL or keyword.

destination_url—The location of the destination file to be copied. It can be a URL or a keyword.
