GarrettCom ES42 manual Maximum Ethernet Segment or Domain Lengths

ES42 Series Edge Switches Installation and User Guide (05/05)

Address buffer age-out time: 300 sec.

Packet buffers memory: 128KB, dynamically shared on all domains

Latency (not including packet time): 100 to 10 Mbps: 5∝s 10 to 100Mbps: 15∝s

Path Delay Value: 50 BT on all ports

LLL(Link-Loss-Learn):Factory default is activated on port 1 and 2

(allow to flush the internal address buffer , and qualify to use with S-Ring and RSTP for faster recovery in ring topology)
