I am trying to get Mellanox QSFP cables (MC220731V / Active Fiber 40Gb/s, see attached picture) to work between a variety of vendor switches. However, I cannot get it to work on our Cisco Nexus 6004, but I can get the cable to work on Cisco Nexus 3172s and Arista switches just fine.
I have enabled support for 3rd party transceivers by enabling them with "service unsupported-transciever" and have other 3rd party cables that work just fine on it like a TrippLite Twinax cable.
When I plug the cable in to the 6004 I get the following message:
6004# 2015 Jun 26 13:27:12 DCO-6004-1 %ETHPORT-3-IF_NON_CISCO_TRANSCEIVER: Non-Cisco transceiver on interface Ethernet6/1 is detected
Here are the additional details about the cable:
6004# sh interface transceiver details
Ethernet6/1
transceiver is present
type is QSFP Unknown Type-(unknown)
name is Mellanox
part number is MC220731V-003
revision is A1
serial number is DC501401368
nominal bitrate is 14100 MBit/sec
Link length supported for copper is 3 m
cisco id is –
cisco extended id number is 0
DOM is not supported
We are setting up a test environment where we will be running equipment off of Cisco and Mellanox switches. We would prefer to use and run only one set of cables between everything. I am aware that Cisco does not support 3rd party cables/transceivers, but neither does Mellanox. So we have to choose somebody and Mellanox is about 1/3 cheaper with quotes on their cables.
Any help or advice would be greatly appreciated.
