Cisco Cisco IPS 4255 Sensor 릴리즈 노트

For the procedure for reimaging sensor, refer to 

For the procedure for copying the backup configuration to a reimaged sensor, see 

To upgrade the sensor, follow these steps:

Download the upgrade file (IPS-K9-5.1-8-E2.pkg) to an FTP, SCP, HTTP, or HTTPS server that is 
accessible from your sensor.

If you use FTP or SCP protocol, you are prompted for a password. If you use SCP protocol, you 
must add the remote host to the SSH known hosts list. 

If you use HTTPS, the remote host must be a TLS trusted host. 

You must log in to Cisco.com using an account with cryptographic privileges to download software. The 
first time you download software on Cisco.com, you receive instructions for setting up an account with 
cryptographic privileges. 

Do not change the filename. You must preserve the original filename for the sensor to accept the update. 

Log in to the CLI using an account with Administrator privileges.

Upgrade the sensor:

sensor# configure terminal

sensor(config)# upgrade scp://tester@10.1.1.1//upgrade/IPS-K9-5.1-8-E2.pkg

Enter password: ********

Re-enter password: ********

Type 

 to complete the upgrade.

Major updates, minor updates, and service packs force a restart of the IPS processes or a reboot 
of the sensor to complete installation. Inline network traffic is disrupted during the reboot.

Verify your new sensor version:

sensor# show version
