1.4 Port Troubleshooting
Here are some situations that frequently occurs in port configuration and the advised solutions:
Two connected fiber interfaces won’t link up if one interface is set to auto-negotiation but the
other to forced speed/duplex. This is determined by IEEE 802.3.
The following combinations are not recommended: enabling traffic control as well as setting
multicast limiting for the same port; setting broadcast, multicast and unknown destination
unicast control as well as port bandwidth limiting for the same port. If such combinations are
set, the port throughput may fall below the expected performance.
For Combo port, it supports copper-forced mode and sfp-forced mode (default mode), here,
copper port will not be up.
