Solution

The following script is designed to gather relevant debug information related to IPsec VPN issues. Issues may be encountered where the IPsec VPN intermittently goes down or keeps flapping. A script can be used to capture logs automatically. This will help ensure that all necessary data is collected in advance before opening a case with TAC.

Refer to Preparing Windows machine to run Teraterm scripts for instructions on how to use Tera Term.

config system global
    set admin-ssh-grace-time <number_of_seconds> <max 3600 seconds>
end
