3172pq connected to c9500-48Y4C

[Mike Stopper]

Have issue when connection between switches.3172pq to c9500-48Y4C.  The interface is set to 10GB at the 3172 with 1000baseSX, GLC-SX-MMD SFP at each each. The c9500-48Y4C does not have speed setting.  Get a speed mismatch error. Any help is appreciated.  It works when using copper SFPs.

Could you try to configure "speed nonegotiate" under the port-config?

See the following in the "hardware limitations" portion of the release notes:

"The following limitations apply to Cisco QSA Module (CVR-QSFP-SFP10G) when Cisco 1000Base-T Copper SFP (GLC-T) or Cisco 1G Fiber SFP Module for Multimode Fiber are plugged into the QSA module:

• 1G Fiber modules over QSA do not support autonegotiation. Auto-negotiation should be disabled on the far-end devices."
