Mgmt Interface Shows Up as TMM

So I have an F5-VE I'm working on that the Mgmt doesn't ping or accept SNMP requests. I opened a case with F5 and they say my 1.0 interface and my Mgmt interface has the same MAC.

 

tmsh show sys mac-address | grep interface

 

00:50:XX:XX:XX:XX  net interface          1.2                                  mac-address
00:50:XX:XX:XX:XX  net interface          1.1                                  mac-address
00:50:XX:82:b5:aa  net interface          mgmt                                 mac-address
00:50:XX:82:b5:aa  net interface          1.0                                  mac-address
00:50:XX:XX:XX:XX  net interface          1.3                                  mac-address

 

I have never seen anything like this. Has anyone ever seen anything like this and what did you do to fix? My plan is to remove the 1.0 boot and see what happens. Add it back if needed. From all the documents I've looked at when that interfaces is created in VMware it should make a TMM interface is should make the Mgmt interface in the VLAN we specify when building it from the OVA.

  • Review this command output:

    tmsh list /sys db vlan.macassignment  -->> https://my.f5.com/manage/s/article/K14513

    make sure to use vmw-compat  "Specific to VE systems"


    Also, make sure each network adapter and note the MAC addresses after trying to reboot such VE
