Description

This article provides information about the automatic synchronization of the application identification package in a chassis cluster.

Symptoms

  • This is a new feature on 12.1.
  • Prior to 12.1, users had to individually download the application Identification package on each cluster member..

Solution

  • The existing application identification package download feature is modified to download the security package on the primary node. Then the pack is synchronized to the secondary node.
  • This feature enhances the operation needed by the administrator.
  • Additionally, this feature helps to address some difficulties, which arise due to the routing daemon not running on the backup node.

This feature is transparent to the user. Users can use the same CLI command to download the application identification package to the primary node:

{primary:node0}
[email protected]> request services application-identification download
Please use command "request services application-identification download status" to check status
When the package is downloaded and synchronized to the backup node, the download status will be as follows:
{primary:node0}
[email protected]> request services application-identification download status
Downloading application package 2107 succeed.

After the application identification package is downloaded, the content will be automatically synchronized to the backup node. Users can then install the package with the following CLI command:
{primary:node0}
[email protected]> request services application-identification install
node0:
--------------------------------------------------------------------------
Please use command "request services application-identification install status" to check status

node1:
--------------------------------------------------------------------------
Please use command "request services application-identification install status" to check status

After sometime, check status will tell you that both the nodes are installed with the package version:
[email protected]> request services application-identification install status
node0:
--------------------------------------------------------------------------
Install application package 2107 succeed

node1:
--------------------------------------------------------------------------
Install application package 2107 succeed
