Managing Physical Interfaces Basic Parameters Configurations
Step 3 Configure basic parameters for the port:
description 
string
Give a port description for identification.
string
: Content of a port description, ranging from 1 to 16 characters.
shutdown
no shutdown
Use shutdown to disable the port, and use no shutdown to enable the port. When the 
status is enabled, the port can forward packets normally, otherwise it will discard the 
received packets. By default, all ports are enabled.
speed { 10 | 100 | 1000 | auto }
Set the appropriate speed mode for the port.
10 | 100 | 1000 | auto: Speed mode of the port. The options are subject to your actual 
product. The device connected to the port should be in the same speed and duplex 
mode with the port. When auto is selected, the speed mode will be determined by auto 
negotiation.
duplex { auto | full | half }
Set the appropriate duplex mode for the port.
auto | full | half: Duplex mode of the port. The device connected to the port should be in the 
same speed and duplex mode with the port. When auto is selected, the duplex mode will be 
determined by auto negotiation.
flow-control
Enable the switch to synchronize the data transmission speed with the peer device, 
avoiding the packet loss caused by congestion. By default, this feature is disabled.
jumbo 
(Except T1600G-18TS)
Enable Jumbo on the port. For the port with Jumbo enabled, the MTU size is up to 9216 
bytes, thus allowing the port to send jumbo frames. By default, it is disabled and the MTU 
size for frames received and sent on the port is 1518 bytes. 
Step 4 show interface configuration [ fastEthernet 
port
 | gigabitEthernet 
port
 | port-channel 
port-channel-id 
]
Verify the configuration of the port or LAG.
Step 5 end
Return to privileged EXEC mode.
Step 6 copy running-config startup-config
Save the settings in the configuration file.
The following example shows how to implement the basic configurations of port1/0/1, 
including setting a description for the port, making the port autonegotiate speed and 
duplex with the neighboring port, and enabling the flow-control and jumbo feature on 
T1600G-52TS:
