Parameters
interface OPTIONAL) Enter the following keywords and slot/port or number information:
• For a 1-Gigabit Ethernet interface, enter the keyword GigabitEthernet followed
by the slot/port information.
• For a Loopback interface, enter the keyword loopback followed by a number from 0
to 16383.
•
For a Port Channel interface, enter the keywords port-channel followed by the
number. The range of port-channel IDs is 1 to 128.
• For a 10-Gigabit Ethernet interface, enter the keyword TenGigabitEthernet
followed by the slot/port information.
• For SONET interfaces, enter the keyword sonet followed by the slot/port
information.
• For a 40-Gigabit Ethernet interface, enter the keyword FortyGigE followed by the
slot/port information.
• For a tunnel interface, enter the keyword tunnel followed by the slot/port information.
• For a VLAN interface, enter the keyword vlan followed by the VLAN ID. The VLAN

followed by the pe-id /stack-unit unit number / port-ID number.
• For a port extender 10-Gigabit Ethernet interface, enter the keyword peTenGigE
then the pe-id / stack-unit / port-id information. The pe-id range is from 0 to 255;
the stack-unit unit-number range is from 0 to 7; and the port-id range is 25 to 28 or
49 to 52 depending on the PE.
priority-cost (OPTIONAL) Enter a number as the amount to be subtracted from the priority value. The
range is 1 to 254. The default is 10.
Defaults priority cost = 10
