AS7326-56X / AS7726-32X - Management port failure Follow
Model :
AS7326-56X / AS7726-32X
Symptom of problem :
- Failed to communicate with the switch through the management port.
- The management port can NOT link UP properly.
Procedure :
Step1 - Please power cycle to the "ONIE: rescue mode" for troubleshooting
Step2 - Connect a functioning device (PC/Laptop/other) to the switch's management port directly
For example:
PC (Ethernet Port) <--> (MGMT port) AS7326-56X / AS7726-32X
Step3 - Execute the command "ethtool eth0" to check the management port status
Check the "link detected:", if it shows "yes" which means the management port is linked UP properly. Then you can go to step 4.
ONIE:/ # ethtool eth0
Settings for eth0:
Supported ports: [ FIBRE ]
Supported link modes: 1000baseT/Half 1000baseT/Full
Supported pause frame use: No
Supports auto-negotiation: Yes
Advertised link modes: 1000baseT/Half 1000baseT/Full
Advertised pause frame use: Symmetric
Advertised auto-negotiation: Yes
Speed: 1000Mb/s
Duplex: Full

Link detected: yes
If the "link detected" shows "no", it means the management port is linked DOWN.
Please check the below item to make sure whether the management port can link up:
- Replace another RJ45 ethernet cable.
- Connect the management port to other switches/devices.
If the management port still can NOT link up after the above steps, please return the unit back for RMA repair service.
Step4 - Ping Test
If it links UP properly between the device (PC/Laptop/other) and the switch's management port. And you can do the simple ping test to make sure your device can communicate with the switch via the management port.
