Function:
Sets the cable types supported by the Ethernet port; the “
no mdi
” command
sets the cable type to auto-identification. This command is not supported on ES3628EA’s
ports of 1000Mbps or more, these ports have auto-identification set for cable types.
Parameters:
auto
indicates auto identification of cable types;
across
indicates crossover
cable support only;
normal
indicates straight-through cable support only.
Command mode:
Interface Mode
Default:
Port cable type is set to auto-identification by default.
Usage Guide:
Auto-identification is recommended. Generally, straight-through cable is
used for switch-PC connection and crossover cable is used for switch-switch connection.
Example:
Setting the cable type support of Ethernet ports 0/0/5 -8 to straight-through
cable only.
Switch(Config)#interface ethernet 0/0/5-8
Switch(Config-Port-Range)#mdi normal
3.2.1.2.7 negotiation
Command: negotiation
no negotiation
Function:
Enables/Disables the auto-negotiation function of a 1000Base-T port.
Command mode:
Port configuration Mode
Default:
Auto-negotiation is enabled by default.
Usage Guide:
This command applies to 1000Base-T interface only. The
negotiation
command is not available for 1000Base-FX interface. For combo port, this command
applies to the 1000Base-TX 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 Switch 1 is connected to port 1 of Switch 2, the following will enable
the negotiation for both ports.
SwitchA(Config)#interface E0/0/1
SwitchA(Config-Ethernet0/0/1)#negotiation
SwitchB(Config)#interface E0/0/1
SwitchB(Config-Ethernet0/0/1)#negotiation
