An electrical port of a WLAN device cannot go Up

1. After a 100M/1000M electrical port on a WLAN device is connected to a port on the peer device, configure the electrical port to work in auto-negotiation mode.
2. If the fault persists, check whether the port on the peer device works in auto-negotiation mode.
3. If the port still cannot go Up when a Huawei WLAN device is connected to a non-Huawei WLAN device, configure ports on both devices to work in forcible mode.
4. If the fault persists, perform a loopback test by connecting the electrical port to another port on the same card on the Huawei device using an Ethernet cable.
- If the electrical port goes Up, the peer device may be faulty. Contact the vendor of the peer device to rectify the fault.
- If the fault persists, connect the Ethernet cable to another port on the same card. If the electrical port still cannot go Up, the card is faulty. Contact Huawei technical support personnel to rectify the fault.
