interface media speed issues

Hi, my network is using 100baseTX but on the VE config file it shows it's configured 10GbaseT full. I'm trying to change it but no luck.

 

 

I tried the SOL7612 and also tried using the SCF (import/export) and it errors out on the interface being invalid.

 

Will 10GbaseT work on 100baseTX? From the looks of it, it doesn't. I was thinking of setting it to auto but it keeps on saying the interface is invalid.

 

 

Help! Thanks for any info.

  • What you're seeing is the reported speed of the vnic to the vSwitch. This will always be at 10 gig.

     

     

    The uplink for the vSwitch can change in speed - but this is independent of the BIG-IP VE.

     

     

    In other words, this is perfectly normal. You don't need to change the BIG-IP VE interface's speeds and duplexity from the stock settings.

     

     

     

    This is part of the BIG-IP VE 10.2 release notes, perhaps it will help you: (beyond this, you could edit the .scf (which I presume is from another platform?) and remove the interface specific settings before import)

     

     

    Use of Single Configuration File (SCF) feature (CR137597)

     

    Copying an SCF from a VMware host system to an F5 hardware platform causes an error related to interface mismatching. To work around this issue, save the bigip.conf and bigip_sys.conf files within BIG-IP VE, copy the files to the new platform, and then, on the new platform, run the commands bigpipe merge bigip.conf and bigpipe merge bigip_sys.conf.

    You're right the speed is for the vSwitch which is 10gig.

     

    It turned out the ESX MAC addresses and VLAN ports are all mixed up. After carefully matching them with the uplink switches, everything worked fine.

     

     

     

    Thanks.
  • That happens if NICs are added after booting the VE for the first time (this is a common thing to do)

     

     

    Note: this will likely change the order of your NICs again... but this is the "proper" method for 10.2 and 10.1:

     

     

    1) rm -f /var/db/mcp*

     

    2) reboot the VE

     

    3) Once back in, you should have NICs lined up to the VMware configuration. If not, line them up by comparing MAC addresses shown in the viclient to the mac address shown with "b interface all mac addr show" at the BIG-IP command line.
