interface-type interface-number
] } &<1-10>, where &<1-10> means that you can
provide up to 10 port indexes/port index ranges for this argument.
instance-id
: MSTI ID ranging from 0 to 16. The value of 0 refers to the CIST.
cost
: Path cost to be set for the port. The range of the
cost
argument varies with the
standard used for calculating the default path cost of a port as follows:
z
With the IEEE 802.1D-1998 standard selected, the path cost of an Ethernet port
ranges from 1 to 65535.
z
With the IEEE 802.1t standard selected, the path cost of an Ethernet port ranges
from 1 to 200000000.
z
With the proprietary standard selected, the path cost of an Ethernet port ranges
from 1 to 200000.
Description
Use the
stp interface cost
command to set the path cost(s) of the specified port(s) in a
specified MSTI in system view.
Use the
undo stp interface cost
command to restore the default value of the path
cost(s) of the specified port(s) in the specified MSTI in system view.
By default, a switch automatically calculates the path costs of a port in different MSTIs
based on a specified standard.
If you specify the
instance-id
argument to be 0 or do not specify this argument, the
stp
interface cost
command sets the path cost(s) of the specified port(s) in the CIST.
The path cost of a port affects its port role. By configuring different path costs for the
same port in different MSTIs, you can make flows of different VLANs travel along
different physical links, so as to achieve VLAN-based load balancing. Changing the
path cost of a port in an MSTI may change the role of the port in the instance and put it
in state transition.
The default port path cost varies with port speed. Refer to
Table 1-8
for details.
