I am looking at a IPSec site-to-site VPN connection routers configuration and I see that one router has the transform set mode tunnel and the other side has transform set mode transport. Will this be a problem? The tunnel is up and running. But I am not sure if there are any errors in the background. Thanks

For a site-to-site tunnel you should be using the tunnel mode. I would make sure they match on both ends.

Agree with naderz, both sides should be the same,

On router to router vpn you should use tunnel mode on both sides, check the link below for a good explanation of both modes and when to use;

What does it mean to be "Always On"?

Is your cloud always on? With an Always On cloud you won't have to worry about downtime for maintenance or software application code updates, ensuring that your bottom line isn't affected.

I am not sure what devices you are using. Here is the command for a Cisco device

show crypto ipsec sa

Here is another link that also explains the different modes and their intent:
