4.4.4.2 RSTP Aggregated Port Settings
Click the option
RSTP Aggregated Port Settings
from the
Rapid Spanning Tree
menu
and then the following screen page appears.
State:
Enable or disable configured trunking groups in RSTP mode.
Cost:
This parameter is used by the RSTP to determine the best path between devices.
Therefore, lower values should be assigned to ports attached to faster media, and higher
values assigned to ports with slower media. 0 means auto-generated path cost.
Priority:
Choose a value between 0 and 240 to set the priority for the port interface. A
higher priority will designate the interface to forward packets first. A lower number denotes a
higher priority.
Edge:
If you know a port is directly connected to an end device (that doesn't support RSTP)
then set it as an edge port to ensure maximum performance. This will tell the switch to
immediately start forwarding traffic on the port and not bother trying to establish a RSTP
connection. Otherwise, turn it off.
Point to Point:
“Forced True” parameter indicates a point-to-point (P2P) shared link. P2P
ports are similar to edge ports; however, they are restricted in that a P2P port must operate
in full duplex. Similar to edge ports, P2P ports transit to a forwarding state rapidly thus
benefiting from RSTP.
“Forced False” indicates that the port cannot have P2P status.
“Auto” allows the port to have P2P status whenever possible and operates as if the P2P
status were true. If the port cannot maintain this status, (for example if the port is forced to
half-duplex operation) the P2P status changes to operate as if the P2P value were false.
The default setting for this parameter is true.
