VSP7400 SMLT to IBM AS400

[TobiasW]

Hi guys,

has anyone tried to connect an IBM AS400 to an VSP7400 cluster using an SMLT?
My customer and I tried this today, and had very strange phenomenons with this setup. Internal, everything was fine, but since the Sophos Firewall couldn’t access the AS400 through the SMLT, every connection using a VPN failed…

Does anyone may have a hint for me?

Thanks and stay safe!

Hi Roger, the SMLT Ports are Access Ports to the customers internal LAN, there are all I-SIDs configured. If you mean the vIST VLAN, the answer is Yes as well 😉

If I shutdown one of the SMLT Member Ports, everything is fine. If I activate the port again, the SMLT comes up, everything’s fine, but the connection via VPN is dead…

Best Regards

did you configure the ISIDs for the VLANs on both VSPs, this is a common mistake when setting up a vIST?
