[c-nsp] Port-channel not working Juniper vs Cisco

[james list]

Dear expert
we've an issue in setting up a port-channel between a Juniper EX4400 and a
Cisco Nexus N9K-C93180YC-EX over an SX 1 Gbs link.

We've implemented the following configuration but on Juniper side it is
interface flapping while on Cisco side it remains down.
Light levels seem ok.

Has anyone ever experienced the same ? Any suggestions ?

Thanks in advance for any hint
Kind regards
James
