Revision Date Comment 1.0 20-JUN-2013 Initial Public Release
Products Affected C160 M160 S160
C160, S160, and M160 products shipped with BIOS 1.4.3I experience performance degradation and will not perform at the full CPU capacity.
Cisco manufacturing recently discovered an incorrectly configured BIOS firmware that impacts a number of C160, S160, and M160 appliances shipped to customers.
System performance can be up to 40% lower than appliances with other BIOS versions.
The device shows BIOS version 1.4.3I. In order to verify the version, enter the version command in the appliance CLI:
160_model> version
Product: Cisco IronPort C160 Messaging Gateway(tm) Appliance Model: Either C160, S160, M160
Version: AsyncOS version
Build Date: date value
Install Date: date value
Serial #: serial of appliance BIOS: 1.4.3I <<<< old BIOS number RAID: 02 RAID Status: OPTIMAL RAID Type: 1 BMC: 1.79
This problem is fixed in a new BIOS firmware for C160, M160, and S160 Cisco Content Security Appliances.
If you have an appliance affected by this issue, complete these steps in order to upgrade your BIOS firmware:
- Access the CLI interface.
Note: For the upgrade to run correctly, you must run it from the CLI.
- From the CLI, enter upgrade. A list of available upgrades displays.
The update for BIOS firmware package is provisioned only for appliances that require the upgrade. If you run a supported version of AsyncOS and you do not see the Update for BIOS firmware package in the list of available upgrades, you can assume that your appliance does not require the upgrade and you can skip any further upgrade steps.
- Choose the package Update for BIOS firmware.
- You will be prompted to reboot your machine. Click Yes.
- Wait approximately fifteen minutes. Your machine should automatically reboot after approximately fifteen minutes.
Caution: If your machine does not automatically reboot in fifteen minutes, contact the Technical Assistance Center (TAC). Do not attempt to reboot your machine again.
- In order to verify that the upgrade ran successfully, run the upgrade script again after the machine reboots. If the upgrade was successful, the upgrade script indicates that the appliance does not require an upgrade.
In order to verify the new BIOS firmware version, enter the version command:
160_model> version
