Mgmt ip address config

Hello, F5 interface initial config like below. Question is command "sudo ifconfig mgmt 10.0.100.112/24" is added to F5, why command "show /sys ip-address" shows another different mgmt ip address 192....

Thanks for your reply. My question is I already used two commands for adding mgmt ip. so which one is correct? One is 10.0.100.112, and other is 192.168.1.245

    Hello,

    I tried your command, and found the below results.

    when modified my mgmt IP using linux command, the mgmt IP was updated when showing #ifconfig, but on the tmsh and F5 GUI (platform tab for example), it was still showing the old IP. But i was able to access the F5 GUI and SSH using the new mgmt IP. (and the old mgmt IP was not accessible, which mena sthat there is no two mgmt IPs)

     

    The mgmt IP never gets updated to the TMSH and GUI. If you restarted the F5 or the tmm service, the old IP is reverted back and overwrite the newly created one that was created by the linux command.

    I think the "The TMM is separate from the Linux kernel", and the new mgmt IP was not updated automatically to the tmm.

    I recommened not to update any IPs using the linux command line, and modify them using tmsh or configuraiton utility.

    BR,
