
CIST Ports:
CIST Ports Settings menu allows configuring ports parameters to be used in the
Spanning Tree function. This menu is divided in two tables, one for CIST Aggregated
Port Configuration and another for CIST Normal Port Configuration. If aggregation
function is being performed by the switch, the first table will be used to configure
specific parameters for aggregated ports.
If one configuration is desired to be applied at all instances, then the row “*” should
be used, that is, configuration done in the “*” row will be replied to all instances.
Possible configurations are as follows.
o
CIST Aggregated Port Configuration:

Port : shows the aggregated ports to be configured at this
row;

STP Enabled : enable STP function at the port. Checkbox
selected means STP enabled, and checkbox empty means
disabled;
 Path Cost : indicates the path cost value that will be
announced by the port to other bridges. Lower path costs
mean higher port speed, and they are chosen to forward
traffic at the expenses of higher path costs. Allowed
values are Auto and Specific. If Auto is selected, path
costs will be calculated based on port speed capabilities
as recommended at the 802.1D standard. If Specific is
selected, path cost used will be the path cost defined by
user at the field allowed in the Path Cost column. Allowed
path costs values are integer values from 1 to 200000000;

Priority : indicates the priority of the port. If there are two
paths between Bridges with the same path cost, the
priority field will be used to choose which port should
forward traffic. Lower values mean higher priority for the
port. Allowed values are integer numbers from 0 to 240;

Admin Edge : indicates status flag of the Edge operation
when port is initialized. Allowed values are Non-Edge and
Edge. Non-Edge means that Edge operation flag will be
initialized with value equal 0, and Edge means that Edge
operation flag will be initialized with value equal 1;

Auto Edge : enable Auto-Edge port detection at the port.
This checkbox allows the switch to detect if a port is an
Edge or Trunk spanning tree port automatically. Checkbox
selected means Auto-edge detection enabled, and
checkbox empty means disabled;
