350-601 Storage Network Practice Question
An engineer is troubleshooting a SAN that uses FCoE. The FCoE Initialization Protocol (FIP) discovery phase is failing for one server. The server is connected to a Cisco Nexus switch configured for FCoE. Which command should be checked first?
⚠ Common exam trap
Cisco often tests the distinction between FCoE VLAN configuration (show vlan fcoe) and DCBX/PFC settings, trapping candidates who confuse FIP discovery failures with lossless fabric issues.

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
✓
show vlan fcoe
The FCoE Initialization Protocol (FIP) discovery phase relies on FCoE VLANs being properly configured and active on the switch. The 'show vlan fcoe' command displays the FCoE VLANs and their status, which is the first place to check when FIP discovery fails because the server must be in the correct FCoE VLAN to discover the FCF (FCoE Forwarder). If the FCoE VLAN is missing or not mapped correctly, FIP discovery will fail.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✓
show vlan fcoe
Why this is correct
This command shows FCoE VLANs and VSAN mappings, which are critical for FIP.
- ✗
show npv status
Why it's wrong here
NPV is for FC, not directly for FCoE FIP.
- ✗
show dcbx parameters
Why it's wrong here
DCBX parameters affect link-level but not FIP discovery.
- ✗
show priority-flow-control
Why it's wrong here
PFC is necessary for lossless behavior but not for FIP discovery.
