To change the port Spanning Tree mode for the flat mode instance, use either the
command or the
command. Note that both commands are available
when the switch is running in either mode (1x1 or flat) and an instance number is not required. For exam-
ple, the following commands configure the connection type for port 1/24 for the flat mode instance:
ple, the following commands configure the connection type for port 1/24 for the flat mode instance:
-> bridge 1/24 connection ptp
-> bridge cist 1/24 connection ptp
As in previous releases, it is possible to configure the flat mode instance with the bridge slot/port connec-
tion command by specifying 1 as the instance number (e.g., bridge 1 1/24 connection noptp). However,
this is only available when the switch is running in the flat mode and STP or RSTP is the active protocol.

this is only available when the switch is running in the flat mode and STP or RSTP is the active protocol.
Note that the bridge slot/port connection command only configures one port at a time.
Connection Type on Link Aggregate Ports
Physical ports that belong to a link aggregate do not participate in the Spanning Tree Algorithm. Instead,
the algorithm is applied to the aggregate logical link (virtual port) that represents a collection of physical
ports. To change the port connection type for a link aggregate, use the bridge slot/port connection
commands described above, but specify a link aggregate control number instead of a slot and port. For
example, the following command defines link aggregate 1, associated with VLAN 755, as an edge port:

Configuring Edge Port
By default, auto-edge functionality is enabled on the ports which implies that the Spanning Tree automati-
cally determines the operational edge port status of the ports.
cally determines the operational edge port status of the ports.
The auto-edge functionality can be enabled or disabled on a port in the flat mode Common and Internal
Spanning Tree (CIST) instance by using the
Spanning Tree (CIST) instance by using the
command. Similarly a port in
1x1 instance can be configured by using the
command.
To disable the auto-edge functionality of a port in CIST instance, enter the following command:
-> bridge cist 8/23 auto-edge disable
To enable the auto-edge functionality of the port, enter the following command:
-> bridge cist 8/23 auto-edge enable
The administrative edge port status (admin-edge) is used to determine the status of the port when auto-
matic edge port configuration (auto-edge) is disabled.
matic edge port configuration (auto-edge) is disabled.
To define the administrative edge port status (admin-edge) of a port in a CIST instance, use the
command. Similarly for a port in 1x1 instance, use the
command.
Note. If auto-edge is enabled on a port, then the admin-edge value is overridden.
To enable the administrative edge port status for a port in CIST mode, enter the following command:
-> bridge cist 8/23 admin-edge disable
