Configuring Spanning Tree Port Parameters Configuring Spanning Tree Parameters

To change the port connection type for a VLAN instance, specify a VLAN ID with the bridge slot/port
connection command when the switch is running in the 1x1 mode. For example, the following command
defines an edge port connection type for port 8/1 associated with VLAN 10.
-> bridge 10 8/1 connection edgeport
The explicit bridge 1x1 slot/port connection command configures the connection type for a VLAN
instance when the switch is running in either mode (1x1 or flat). For example, the following command
performs the same function as the command in the previous example:
-> bridge 1x1 10 8/1 connection edgeport
To change the port Spanning Tree mode for the flat mode instance, use either the bridge slot/port connec-
tion command or the bridge cist slot/port connection 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:
-> 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 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 12, “Configuring Static Link
Aggregation,” and Chapter 13, “Configuring Dynamic Link Aggregation.”
