Symptoms

When using the system diagnostics net-utils tcpdump command and pressing Tab for completion, the CLI only lists the available keywords and flags, but does not display any descriptive information for those options.

Impact

Users only see a list of possible completions (such as --timeout, -c, -w, bpf, count, filter, outfile) with no description of what each option does. This makes the interface less user-friendly, forces users to rely on external documentation or prior knowledge, and can slow down troubleshooting or diagnostics activities.

Conditions

This occurs when a user runs: appliance-1# system diagnostics net-utils tcpdump <Tab> on the appliance CLI to view available tcpdump options under net-utils

Workaround

None.

Fix Information

After the fix, when the user enters: system diagnostics net-utils tcpdump <Tab> The CLI will display both possible completions and brief descriptions for each option, similar to the behavior of the system diagnostic tcpdump command. This provides inline guidance on tcpdump parameters, improving usability and reducing the need to reference external documentation.
