Adding A Description For An Interface - Cisco WS-C3550-12G Software Configuration Manual

Chapter 8 Configuring Interface Characteristics
Beginning in privileged EXEC mode, follow these steps to configure flow control on an interface:
Command
Step 1
configure terminal
Step 2
no mls qos
Step 3
interface interface-id
Step 4 flowcontrol {receive | send} {on | off | desired} Configure the flow control mode for the port.
Step 5
end
Step 6
show interfaces interface-id
Step 7 copy running-config startup-config
To disable flow control, use the flowcontrol receive off and flowcontrol send off interface
configuration commands.
This example shows how to turn off all flow control on Gigabit Ethernet interface 0/1 and to display the
results:
Switch# configure terminal
Switch(config)# interface gigabitethernet0/1
Switch(config-if)# flowcontrol receive off
Switch(config-if)# flowcontrol send off
Switch(config-if)# end
Switch# show interfaces gigabitethernet0/1
GigabitEthernet0/1 is up, line protocol is down
Hardware is Gigabit Ethernet, address is 0002.4b29.2e01 (bia 0002.4b29.2e01)
MTU 1500 bytes, BW 1000000 Kbit, DLY 10 usec,
Encapsulation ARPA, loopback not set
Keepalive set (10 sec)
Auto-duplex, Auto-speed
input flow-control is off, output flow-control is off
