There is a command group 'az_network_vpn connection_ipsec policy'. This group of commands could 'manage vpn connection ipsec policies'. The group of commands has global parameter '--debug' which means 'Increase logging verbosity to show all debug logs.'. The group of commands has global parameter '--help -h' which means 'Show this help message and exit.'. The group of commands has global parameter '--only-show-errors' which means 'Only show errors, suppressing warnings.'. The group of commands has global parameter '--output -o' which means 'Output format.'. The group of commands has global parameter '--query' which means 'JMESPath query string. See <a href="http://jmespath.org/">http://jmespath.org/</a> for more information and examples.'. The group of commands has global parameter '--subscription' which means 'Name or ID of subscription. You can configure the default subscription using `az account set -s NAME_OR_ID`.'. The group of commands has global parameter '--verbose' which means 'Increase logging verbosity. Use --debug for full debug logs.'. This group contains a child command 'az_network_vpn connection_ipsec policy_add'.The syntax is: az network vpn-connection ipsec-policy add --connection-name

                                           [--no-wait {0, 1, f, false, n, no, t, true, y, yes}]. The 1th example of the child command would be to use it to 'add specified ipsec policies to a connection instead of relying on defaults', the syntax is: az network vpn-connection ipsec-policy add -g MyResourceGroup --connection-name MyConnection --dh-group DHGroup14 --ike-encryption AES256 --ike-integrity SHA384 --ipsec-encryption DES3 --ipsec-integrity GCMAES256 --pfs-group PFS2048 --sa-lifetime 27000 --sa-max-size 102400000. The parameter '--connection-name' is required. It is used to connection name.. The parameter '--dh-group' is required. It is used to the dh groups used for initial sa.. The parameter '--ike-encryption' is required. It is used to the ike encryption algorithm.. The parameter '--ike-integrity' is required. It is used to the ike integrity algorithm.. The parameter '--ipsec-encryption' is required. It is used to the ipsec encryption algorithm.. The parameter '--ipsec-integrity' is required. It is used to the ipsec integrity algorithm.. The parameter '--pfs-group' is required. It is used to the pfs groups used for new child sa.. The parameter '--resource-group -g' is required. It is used to name of resource group. you can configure the default group using `az configure --defaults group=<name>`.. The parameter '--sa-lifetime' is required. It is used to the lifetime in seconds for p2s client.. The parameter '--sa-max-size' is required. It is used to the payload size in kb for p2s client.. The parameter '--no-wait' is optional. do not wait for the long-running operation to finish..
