SSH timeout - Catalyst 9000 Always-On Sandbox

jkoegel — Tue, 09 Jun 2026 13:22:56 GMT

Hi All,

after starting VPN I cannot reach the IP Address 10.10.20.181 of the Cat9k via SSH. Ping also does not work. VPN is up and routing table looks fine. Any ideas?

Hello @jkoegel

No ACL on C9k ? route return is ok too ?

cannot access the C9k CLI without SSH, so I cannot check. Is there another console access possible?

I pinged the team to reset the Always-On Cat9k sandbox. If you are using VPN, then that's another sandbox different from the original post. Create a new post with the details of which sandbox you are using and what works and what doesn't.

My bad, I see the original user who posted said VPN. That being said, Always-On sandboxes don't use VPN
