To login into the Cisco Nexus server with SSH you need to use the following adjusted ssh command. Assuming you are on a linux computer. In this specific case this works for Debian Gnome.
ssh -o HostKeyAlgorithms=+ssh-rsa dpasn@10.18.81.151

To allow multiple VLANs on a Cisco Nexus switch, use the command: switchport trunk allowed vlan <vlan-list> where <vlan-list> can be a range or specific VLAN IDs. For example, to allow VLANs 10, 20, and 30, you would enter switchport trunk allowed vlan 10,20,3
