Exhibit
Refer to the exhibit. <error> 2023-01-15 10:23:45 FCSWITCH %FABRIC-3-DOMAIN_ID_CONFLICT: Domain ID 0x64(100) is already in use by switch wwn 10:00:00:00:c9:aa:bb:cc </error>
Refer to the exhibit. An engineer sees this error on a Cisco MDS switch. What is the best action to resolve the issue?
⚠ Common exam trap
Cisco often tests the misconception that a link flap or reboot will fix a domain ID conflict, when in fact the root cause is a duplicate domain ID that must be manually changed on one switch.
Answer choices
Why each option matters
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
Assign a different domain ID to one of the switches.
The error indicates a domain ID conflict between two switches in the same VSAN. In Fibre Channel fabrics, each switch must have a unique domain ID to build a correct forwarding table. Assigning a different domain ID to one of the switches resolves the conflict without disrupting the fabric.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
Reload both switches to reset domain IDs.
Why it's wrong here
Reloading may cause temporary resolution but the conflict may recur upon re-joining.
- ✗
Shut and no shut the ISL between the switches.
Why it's wrong here
This may cause a brief disruption but does not resolve the root cause.
- ✓
Assign a different domain ID to one of the switches.
Why this is correct
Each switch in a fabric must have a unique domain ID.
- ✗
Change the VSAN on one of the switches.
Why it's wrong here
Changing VSAN may change the domain ID but is not the standard solution.
