• Automatic MDIX support

• Supports transparent VLAN forwarding

• Packet length of up to 1536 bytes

• Fault propagation of line interface error conditions to Ethernet port (optional

feature)

• When filtering is enabled, there are two QoS levels via two priority queues to

handle priority, which is determined in the following order:

 If the packet received is an Ethernet tagged frame, product marks the

packet according to the tag priority (0–7).

 0–3: low priority queue

 4–7: high priority queue

 Otherwise, LRSI-F-27 marks the packet according to IP ToS priority (0–7).

 0–3: low priority queue

 4–7: high priority queue

 Untagged and non-IP frames enter the low priority queue

• Product frames egress from the queues with a 1:2 ratio, two frames from

high priority, one frame from low priority

• The products buffer holds 120 frames (of 64 bytes).
