Nexus 3k Port-channel

[fhoban]

Hi All, Am having issues getting a N3K up on a port-channel to a N9K VPC. Eth/-47 - 48 on N3K > eth1/24 on N9K1 and N9K2 VPC. Error message is

 %ETHPORT-3-IF_NON_CISCO_TRANSCEIVER: Non-Cisco
 transceiver on interface Ethernet1/47 is detected

Transceivers-Cables= Cisco+

N9K

transceiver is present
    type is SFP-H10GB-CU5M
    name is CISCO-TYCO      
    part number is 1-2053783-3     
    revision is T   
    serial number is TED1927C2Y8     
    nominal bitrate is 10300 MBit/sec
    Link length supported for copper is 5 m
    cisco id is 3
    cisco extended id number is 4
    cisco product id is SFP-H10GB-CU5M     

N3K

transceiver is present
    type is SFP-H10GB-CU5M
    name is CISCO-LOROM     
    part number is LRHSPB54A050    
    revision is B2

    nominal bitrate is 10300 MBit/sec
    Link length supported for copper is 5 m

    cisco extended id number is 4

This is happening at 2 DC's with identical configuration. TAC has mentioned bug bug CSCuc86978, configuring 'service-unsupported-transceiver' and reboot switch. I've tried this already with no luck.

Recommendation now to reseat SFP and reboot. Anybody encountered this before.

N3K n3500-uk9.6.0.2.A6.3.bin

N9K nxos.7.0.3.I2.2b.bin

Thanks!

I have had a similar issue before.. Nexus 5k with Cisco brand SFP modules that fail to register in certain ports. We were lucky enough to have spare ports on the switch that for some reason accepted the SFP's. Sorry this doesn't answer your question, but you are not alone.

thanks.I will try a different port to see as well. currently same ports on 2 different sites with exact same results.

Changing mode to 'on' on port-channels brings up one side of the channel only.
