Will there be any network glitch during failover from active to Standby ?

Hi,

It’s down to personal preference whether you wish to failover using the GUI or CLI.

To failover using the CLI, run this on the active unit:

tmsh run sys failover standby

There will most likely be a bit of disruption when failing over depending on your configuration.

If you want connections to be mirrored from the active to the standby you need to enable connection mirroring on the virtual server (this is turned off by default). Connection mirroring is useful on FTP virtual servers (long lived connections) and TCP based IP forwarding virtual servers, but not necessary on HTTP virtual servers (short lived connections). You need to consider the extra overhead for enabling connection mirroring.

If you wish for persistence records (e.g. source IP) to be mirrored then you will also need to enable mirror persistence on the persistence profile.
