HI,
I am trying new Intel controller with sr-iov functions , and there are 2 problems with VF creation once the SFPs are connected to the swich and the link is UP.
- During server boot there is strange message ": Non-contiguous TC "
- If I am truing to create VF after OS is loaded :
if the link is up - VF failed .
if the link is down VF created , but cannot get line rate .
If the server loaded without link UP - everything works perfectly.
log example :
Feb 12 17:28:22 FORTIpoc1 kernel: i40e 0000:05:00.0: couldn't add VEB, err I40E_ERR_ADMIN_QUEUE_ERROR aq_err I40E_AQ_RC_ENXIO
Feb 12 17:28:22 FORTIpoc1 kernel: i40e 0000:05:00.0: couldn't add VEB
Feb 12 17:28:22 FORTIpoc1 kernel: i40e 0000:05:00.0: add vsi failed for VF 0, aq_err 6
the " Non-contiguous TC " message during the bootloader , long before kernel .
Same issue i have on two differen HP servers G10 and G9
also Redhat 7 and Centos7.7 OS

Hello Ruslan,
Thank you for the reply.
Can you share the exact error message you got when using the Juniper 4500? This would help us in further investigating the issue.
Just to clarify, if you tried to connect any of your servers to Cisco 9300, you don't encounter any issues on VF creation or SR-IOV functions and the problem is only specific to Juniper 4500? Kindly confirm.
Awaiting to hear from you.
