Configuring Spanning Tree Parameters Configuring STP Port Parameters
OmniSwitch 6800/6850/9000 Network Configuration Guide March 2008 page 7-37
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:
-> 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
connection 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 already 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 the link aggregate 10 associated with VLAN 755 as an edge
port:
-> bridge 755 10 connection edgeport
For more information about configuring an aggregate of ports, see Chapter 16, “Configuring Static Link
Aggregation,” and Chapter 17, “Configuring Dynamic Link Aggregation.”
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.
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 bridge cist slot/port auto-edge command. Similarly a port in
1x1 instance can be configured by using the bridge 1x1 slot/port auto-edge 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.
To define the administrative edge port status (admin-edge) of a port in a CIST instance, use the bridge
cist slot/port admin-edge command. Similarly for a port in 1x1 instance, use the bridge 1x1 slot/port
admin-edge 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
