Command Mode
Interface Configuration (Ethernet)
Command Usage
Available sfp-forced modes include:
ECS2100-10T/PE/P: Ports 9-10 (1000BASE SFP) support 1000sfp & 100fx
ECS2100-28T/P/PP: Ports 25-28 (1000BASE SFP) support 1000sfp & 100fx
Example
This forces the switch to use the 1000sfp mode for SFP port 28.
Console(config)#interface ethernet 1/28
Console(config-if)#media-type sfp-forced 1000sfp
Console(config-if)#
negotiation This command enables auto-negotiation for a given interface. Use the no form to
disable auto-negotiation.
Syntax
[no] negotiation
Default Setting
Enabled
Command Mode
Interface Configuration (Ethernet, Port Channel)
Command Usage
◆ 1000BASE-T does not support forced mode. Auto-negotiation should always be
used to establish a connection over any 1000BASE-T port or trunk.
◆ When auto-negotiation is enabled the switch will negotiate the best settings
for a link based on the capabilities command. When auto-negotiation is
disabled, you must manually specify the link attributes with the speed-duplex
and flowcontrol commands.
◆ If auto-negotiation is disabled, auto-MDI/MDI-X pin signal configuration will
also be disabled for the RJ-45 ports.
Example
The following example configures port 10 to use auto-negotiation.
Console(config)#interface ethernet 1/10
Console(config-if)#negotiation
Console(config-if)#
