• Description: 2-port Ethernet Switch With Non-pci Interface And Fiber Support
• Manufacturer: Micrel Semiconductor

The KSZ8862M will not forward the following packets:
1. Error packets.
2. 802.3x pause frames.
3. "Local" packets.

April 2007
These include framing errors, Frame Check Sequence (FCS) errors, alignment errors, and illegal size packet errors.
The KSZ8862M intercepts these packets and performs the flow control.
Based on destination address (DA) look-up. If the destination port from the lookup table matches the port from which
the packet originated, the packet is defined as "local."
