Parameter: <string> is a string, up to 32 characters are allowed.
Command mode: Interface Mode
Default: No name is set by default.
Usage Guide: This command facilitates the management of the switch. The user can
name the ports according to their usage, for example, 1/1-2 ports used by the financial
department, and they can be named "financial”; 2/9 port is used by the engineering
department, and can be named “engineering”; 3/12 port connects to the server, and can
be named “Servers”. Thus the usage of the ports are obvious.
Example: Name ports 1/1-2 as “financial”.
Switch(Config)#interface ethernet 1/1-2
Switch(Config-Port-Range)# descriptionfinancial
Command: negotiation no negotiation
Function: Enable the auto-negotiation function of 1000Base-FX port. Use the “no”
command to disable the auto-negotiation function of 1000Base-FX port. Command mode:
Port configuration Mode
Default: Auto-negotiation is enabled by default.
Usage Guide: This command applies to 1000Base-FX interface only. The negotiation
command is not available for 1000Base-TX or 100Base-TX interface. . For combo port,
this command applies to the 1000Base-FX port only and has no effect on 1000Base-TX
port. To change the negotiation mode, speed and duplex mode of 1000Base-TX port, use
speed-duplex command instead.
Example: Port 1 of Switch1 is connected to port 1 of Switch2, the following will disable the
negotiation for both ports.
Switch1(Config)#interface e1/1
Switch1(Config-Ethernet1/1)# no negotiationSwitch2(Config)#interface e1/1
Switch2(Config-Ethernet1/1)#negotiation

no rate-suppression {dlf | broadcast | multicast}
Function: Sets the traffic limit for broadcast, multicast and unicast for unknown
destination on all ports in the switch; the “no rate-suppression” command disables the
traffic throttle function of broadcast, multicast and unicast for unknown destination on all
