When i am correct you also need to enable igmp.
That was in older Versions mandantory. Maybe it is already enabled on your switch.

    LACP is not a "must have", you need it if you want to have physical HA.
    If there is only one physical interface on proxmox node then you can
    configure one switchport on cisco side as acces/trunk-port - for

    proxmox side:

    auto vmbrxxx
    iface vmbrxxx inet static
            address xxx
            gateway xxx
            bridge_ports xxx
            bridge_stp on
            bridge_fd 3

    cisco side:

    interface GigabitEthernetxxx
     description xxx
     switchport access vlan xxx
     switchport mode access
     no vtp
     spanning-tree portfast edge
     spanning-tree guard root
