350-401 Practice Question: Runs the following command on Switch SW4: SW4#…
A network engineer runs the following command on Switch SW4:
SW4# show etherchannel 1 detail Channel-group number: 1
Group state = L2
Ports in the group: -------------------
Port: Gi0/0 --------
Port state = Up, In-Bundle Channel group = 1 Mode = Active/PagNego Gcchange = - Port-channel = Po1 GC = 0x00010001 Pseudo port-channel = Po1
Port index = 0 Load = 0x00
Flags: S - Device is sending Slow LACPDUs F - Device is sending Fast LACPDUs A - Device is in active mode. P - Device is in passive mode.
Local information:
LACP port Admin Oper Port Port Port Flags State Priority Key Key Number State Gi0/0 SA bndl 32768 0x1 0x1 0x101 0x3D
Partner information:
LACP port Admin Oper Port Port Port Flags State Priority Key Key Number State Gi0/0 SA bndl 32768 0x1 0x1 0x102 0x3D
Age of the port = 0d:00h:15m:20s
Based on this output, what can be concluded?
⚠ Common exam trap
Cisco often tests the misconception that 'Load = 0x00' means the port is idle, but in reality it is a default value for the first port index in the EtherChannel and does not reflect traffic utilization.
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
✓
The port is bundled and the LACP state is synchronized.
The output shows both the local and partner ports in 'bndl' state with LACP state 0x3D, which indicates the port is bundled and synchronized. The 'SA' flags confirm active mode and slow LACPDUs, and the 'bndl' state means the EtherChannel is fully operational with LACP in sync.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
The port is in passive mode and waiting for the partner to initiate.
Why it's wrong here
The 'A' flag in the LACP state indicates active mode, meaning the port actively sends and responds to LACPDUs rather than passively waiting for the partner to initiate. In passive mode, you'd see 'P', and the port would only reply to LACPDUs it receives, not start negotiation.
- ✗
The port is sending fast LACPDUs because the flag is 'F'.
Why it's wrong here
The LACP flags show 'S' for slow periodic transmission, with LACPDUs sent every 30 seconds, not 'F' for fast. Fast mode ('F') would send LACPDUs every second, but that is not the case for this port.
- ✓
The port is bundled and the LACP state is synchronized.
Why this is correct
The port's 'bndl' state in the EtherChannel summary indicates it is successfully bundled into the channel, and the LACP state value 0x3D signifies that the port is synchronized with its peer. This full operational state means the port is actively forwarding traffic as part of the EtherChannel.
- ✗
The port is not in use because the load is 0x00.
Why it's wrong here
The load of 0x00 indicates that the current traffic distribution across the port is zero, but that does not mean the port is unused or out of service. The load value is a snapshot of the traffic hashing at that moment; the port remains bundled and ready to carry traffic, so a zero load simply reflects no active flows currently assigned to it.
