Hop Count Limitation
Loop Prevention on the GS920 Series switch has a hop count limitation.
Each GS920 Series switch has its maximum hop count as shown in
Table 27. The Loop Prevention-enabled switch ignores the Loop
Prevention frame when the hop count in the frame exceeds the maximum
hop count of the switch.
Model
AT-GS920/8PS
AT-GS920/8
AT-GS920/16
AT-GS920/24
If one AT-GS920/16 or AT-GS920/24 switch exist in a topology, Loop
Prevention ignores a Loop Prevention frame when its hop count is over 10.
Allied Telesis recommends designing the network with 10 or less cascade
levels when building a Loop Prevention-enabled network.
