To upgrade the ISA-AA MDA software
Purpose and prerequisites
Perform this procedure to upgrade only the ISA-AA MDA software on an NE, for example, when the new software includes new AA protocol signatures.
Note: You cannot use the procedure to upgrade between major releases; only minor-release ISA-AA upgrades within the same major release are supported.
An ISA-AA MDA software upgrade is an in-service upgrade that does not require an NE reboot. Although the Software Upgrade parameter in the associated software upgrade policy must be selected for the image activation and upgrade to occur, the Software Upgrade Options in the policy do not apply to an ISA-AA MDA software upgrade.
The 7450 ESS and 7750 SR support ISA-AA MDA upgrades.
The following must be true before you attempt an ISA-AA software upgrade.
CAUTION Service Disruption |
Nokia recommends that you open a physical console session on the device that you need to upgrade. The console session allows you to monitor the upgrade and recover in the event of an upgrade failure.
Read the software upgrade information in the device documentation before you perform a software upgrade.
Before you attempt an ISA-AA MDA software upgrade, see the appropriate device release notice and the NSP NFM-P Network Element Compatibility Guide for information about the supported upgrade paths. See NE software upgrade overview for general ISSU information.
Steps

The NFM-P verifies the isa-aa.tim checksum and imports the file to the NFM-P database. An entry for the image is listed on the Software Upgrade form. |
7 |
Select the required ISA-AA image. |
8 |
Click Upgrade Sites. A list of NEs is displayed. Only the devices that support the software image are listed. |

If required, use the NFM-P FTP or SSH file browser to verify that the transferred file and configuration are on each upgraded NE. See To view an NE file system using an FTP file browser for information about using the FTP file browser, and To view an NE file system using an SSH file browser for information about using the SSH file browser. |
17 |
Update each ISA-AA policy, as required, to enable the new protocol signatures. See Chapter 87, Application assurance for information about configuring AA policies. End of steps |
