Command Mode： interface Mode
Default： No port name by default
Usage Guide： This command is for helping the use manage switches, such as the user
assign names according to the port application, e.g. financial as the name of 1/1-2 ports
which is used by financial department, engineering as the name of 1/9 ports which
belongs to the engineering department, while the name of 1/12 ports is assigned with
Server, which is because they connected to the server. In this way the port distribution
state will be brought to the table.
Example： Specify the name of 1/1-2 port as financial
Switch(Config)#interface ethernet 1/1-2
Switch(Config-If-Port-Range)#description financial
3.2.1.2.4 flow control
Command: flow control
no flow control
Function: Enables the flow control function for the port: the “no flow control” command
disables the flow control function for the port.
Command mode: Interface Mode
Default:
Port flow control is disabled by default.
Usage Guide: After the flow control function is enabled, the port will notify the sending
device to slow down the sending speed to prevent packet loss when traffic received
exceeds the capacity of port cache. ES4624-SFP/26-SFP’s ports support IEEE802.3X
flow control; the ports work in half-duplex mode, supporting back-pressure flow control. If
flow control results in serious HOL, the switch will automatically start HOL control
(discarding some packets in the COS queue that may result in HOL) to prevent drastic
degradation of network performance.
Note: Port flow control function is NOT recommended unless the users need a
slow speed, low performance network with low packet loss. Flow control will not
work between different cards in the switch. When enable the port flow control function,
speed and duplex mode of both ends should be the same.
Example: Enabling the flow control function in ports 1/1-8.
Switch(Config)#interface ethernet 1/1-8
Switch(Config-Port-Range)#flow control
3.2.1.2.5 interface Ethernet
Command: interface ethernet
