QSFP Connection between 5220 and Nexus9k QSFP interface question

L0 Member

Has anyone connected Nexus 9k to PA 5220 via the QSFP interface?

If so will the Cisco QSFP-H40G-CU3M 40GBASE-CR4 Passive Copper Cable work? Done research but just not 100 percent if it will work.

Quite a late response, but based on our testing, it will not work.    We tried a Cisco QSFP-H40G-CU1M and while the 3260 recognized the module, link would never come up.  Replacing with a 7M active copper cable worked.   We are hoping that a 1M Active Optic cable will work.   (Cisco QSFP-H40G-AOC1M)   


Edit: fixed typo, the firewall is a PA-3260

These should work on the Cisco side:

transceiver is present
type is QSFP-40G-SR-BD
part number is AFBR-79EBPZ-CS2


So were you replying to me?   If so, are you stating that the QSFP-40G-SR-BD is supported by the PaloAlto Networks PA-3260?    It is clearly supported by Cisco.




Hello @JohnWade,


The short answer would be "Yes".


As OtakarKlier mentioned, QSFP-40G-SR-BD SFPs are compatible with PA- devices and will be visible in the "show system" CLI command, as CISCO-AVAGO. The 1Gbps Cisco SFPs, however, might be seen as CISCO-FINISAR.


I hope this helps.
