Comprehensive and Detailed Explanation (Paraphrased from F5 BIG-IP Administration / Installation / Initial Configuration concepts)
Within the BIG-IP Traffic Management Shell (tmsh), system configuration objects—including the management IP—are organized under the/syshierarchy. The management IP address is a configurable property stored in the system configuration and can be viewed using the tmshlistcommand, which displays configuration objects and their currently assigned values.
Why “list /sys management-ip” is correct
The list command in tmsh is used todisplay configured system values, not runtime statistics.
The object that holds the management IP settings on BIG-IP systems is located at:/sys management-ip
Running the command:list /sys management-ipwill reveal the settings for the management IP interface, including the address, netmask, and any associated attributes.
This is the standard method used during system setup and verification to confirm the management IP configuration.
This behavior aligns with BIG-IP administration procedures, where configuration information is retrieved usinglist, while operational data is retrieved usingshow.
Why the other options are incorrect
A. run /util bash ifconfig mgmt
This command enters the Bash shell, then runs ifconfig to display the management interface.
While this can show the management interface address, it isnot a tmsh-native command, and the question specifically asks for a tmsh command.
Administrators use tmsh directly for configuration display rather than leaving the shell.
C. show /sys management-ip
The show command displaysstatistics or operational data, not configuration values.
The management-ip object does not maintain statistics; therefore show does not return the configuration details required.
Only thelistcommand reveals stored configuration data such as IP address and netmask.
