vPC Issue between 3 N5K switches

So in summary we just got 2 new 5624Q to use as core switches and I'm trying to setup vPC to a 56128 TOR switch. It looks like the 2 core switches see the port-channel up if I'm reading it correctly but the TOR switch isn't seeing the same (SD)

Any help would be much appreciated!

Here are the outputs for the 3 switches:

CORE SWITCH 1

SES-CORE-SW-01(config-if)# sh vpc brief Legend: (*) - local vPC is down, forwarding via vPC peer-link

vPC domain id : 1000 Peer status : peer adjacency formed ok vPC keep-alive status : peer is alive Configuration consistency status : success Per-vlan consistency status : success Type-2 consistency status : success vPC role : primary, operational secondary Number of vPCs configured : 1 Peer Gateway : Disabled Dual-active excluded VLANs : - Graceful Consistency Check : Enabled Auto-recovery status : Enabled (timeout = 240 seconds) vPC Peer-link status

id Port Status Active vlans
