I have a C9500-32QC (Port 33) connected to a C9500-48Y4C (Port 49) via a DAC cable (QSFP-100G-CU5M=) but link doesn't come up.
C9500-32QC-Config
int Hun1/0/33
no switchport
ip address x.x.x.x x.x.x.x
ip ospf network point-to-point
ip ospf area 0

C9500-32QC connected to another C9500-32QC on port 47 & 48 (port-channel) via QSFP-100G-CU1M= comes up just fine.
Any ideas?
