Known Affected Versions:
F5OS-A 1.5.2, F5OS-A 1.5.3, F5OS-A 1.5.4, F5OS-A 1.8.0, F5OS-A 1.8.1, F5OS-A 1.8.2, F5OS-A 1.8.3, F5OS-A 1.8.4
Opened: Sep 10, 2025 Severity: 4-Minor
On F5OS-A platforms, when the management interface is DOWN, the output of the "show system mgmt-ip" command may display all zeroes or default values for the management IP address, prefix-length, and gateway. Example output: system mgmt-ip state ipv4 system address 0.0.0.0 system mgmt-ip state ipv4 prefix-length 0 system mgmt-ip state ipv4 gateway 0.0.0.0 system mgmt-ip state ipv6 system address :: system mgmt-ip state ipv6 prefix-length 0 system mgmt-ip state ipv6 gateway :: This does not reflect the actual configured management IP, which remains correctly set and visible via show running-config system mgmt-ip.
This is a cosmetic issue in the F5OS CLI. The configuration itself is not lost or changed; it remains intact and can be viewed in the running configuration.
Management interface connected to an upstream switch; interface may be administratively shut down or physically disconnected.
-- To view accurate management IP configuration when the mgmt interface is DOWN, use the following command: # show running-config system mgmt-ip -- To avoid hitting this cosmetic issue, ensure that the mgmt interface remains UP and connected to its upstream switch. -- If this issue occurs, toggling the mgmt interface UP/DOWN or rebooting may temporarily resolve it; however, it may recur if the interface goes DOWN again. An upgrade or downgrade also temporarily clears the issue.
