Command to keep the tunnel up

[Loc Nguyen]

Hi,

I have a site to site vpn from ASA to AWS.

I am trying to find  commands to keep the tunnel always up.

Could you advise?

Thanks

Hi @Loc Nguyen 

What type of VPN are you using, Policy Based or Route Based VPN?

If Policy Based (Crypto map) then you'll need to continually be sending traffic over the tunnel. So you could configure a ping or snmp from your local management system to a device on the other end of the tunnel. There is no specific command to keep the tunnel up.

If you are using a Route Based VPN (VTI) then a VTI is always up.

Thanks. I use policy based VPN.
