into the error-disable state (EDS) if an error condition occurs.
vlan vlan-range Enter the keyword vlan then the VLAN numbers. The range is
from 1 to 4094.
cost number Enter the keyword cost then the port cost value. The range is
from 1 to 200000.
Defaults:
• 100 Mb/s Ethernet interface = 200000.
• 1-Gigabit Ethernet interface = 20000.
• 10-Gigabit Ethernet interface = 2000.
• Port Channel interface with one 100 Mb/s Ethernet =
200000.
• Port Channel interface with one 1 Gigabit Ethernet =
20000.
• Port Channel interface with one 10 Gigabit Ethernet =
2000.
