To change the STP path cost for a link aggregate, use the same bridge path cost command, but specify a
link aggregate control number instead of a slot and port. For example, the following command sets the
path cost for link aggregate 29 associated with VLAN 755 to 19:
-> bridge 755 29 path cost 19
For more information about configuring an aggregate of ports, see
Aggregation,"
and
Chapter 11, "Configuring Dynamic Link Aggregation."
To view the STP path cost for a port, use the
this command, see the OmniSwitch CLI Reference Guide.
Configuring Port Mode
There are two port modes supported: manual and dynamic. Manual mode indicates that the port was set by
the user to a forwarding or blocking state. The port will operate in the state selected until the state is
manually changed again or the port mode is changed to dynamic. Ports operating in a manual mode state
do not participate in the Spanning Tree Algorithm. Dynamic mode indicates that the active Spanning Tree
Algorithm will determine port state.
By default, STP is enabled on the port and the port operates in the dynamic mode. If the switch is running
in the 1x1 Spanning Tree mode, then the port mode applies to the specified VLAN STP instance associ-
ated with the port. If the switch is running in the flat Spanning Tree mode, then the port mode applies
across all VLANs associated with the port. VLAN 1 is referenced as the port's VLAN, even if the port is
associated with other VLANs.
To change the mode for a port, enter bridge followed by an existing VLAN ID (or VLAN 1 if using a flat
Spanning Tree instance) then the port's slot/port designation followed by mode and then enter either
forwarding, blocking or dynamic. For example, the following command sets the mode for port 1 on slot
8 for VLAN 10 to forwarding.
-> bridge 10 8/1 mode forwarding
