XSM7224S to Cisco Redundancy/Failover

Hello,

Im trying to figure out how to setup a redundancy/failover connection between XSM7224S and Cisco 3750X.

This is what I have currently:

Netgear Switch 1------------------------------

Netgear Switch 2                                    |

                                                               |

Cisco 3750X Switch 1                             |

Cisco 3750X Switch 2                             |

Cisco 3750X Switch 3------------------------

Cisco 3750X Switch 4

2 Netgear XSM7224S (Stacked).

member 1 1
member 2 1
!stack-port 1/0/24 stack
!stack-port 2/0/24 stack
switch 1 priority 15
switch 2 priority 1

Netgear Switch 1 is connected to our main Cisco Core 3750 via 10GB Fiber Port:

Netgear Config
interface 1/0/2
no auto-negotiate
no port lacpmode
description '10G-Uplink-to-Core'
mtu 9198
vlan participation include x,x,x,x,x,x
vlan tagging x,x,x,x,x,x
mode dvlan-tunnel

Cisco Switch

interface TenGigabitEthernet3/1/1
description P-DC1-ETHSW10G-02 Port 1/0/2
switchport trunk encapsulation dot1q
switchport trunk allowed vlan x,x,x,x,x,x
switchport mode trunk

What Im looking for is to setup a redundancy type connection where if the 1st Netgear switch goes down, the secondary takes over, or if the 3rd Cisco switch goes down, the 4th one takes over. But I dont want to use both at the same time, in other words, I need something like a priority. If this link goes down, then this one takes over.

Something like this:

Netgear Switch 1------------------------------

Netgear Switch 2_______________      |

                                                        |      |

Cisco 3750X Switch 1                      |      |

Cisco 3750X Switch 2                      |      |

Cisco 3750X Switch 3----------------- |-----

Cisco 3750X Switch 4___________|

Thank you very much for your support....
