Force 10 - Link connectivity for DAC (Twinax) cables on Force 10 switches.



Article summary: This article explains how to resolve connectivity issues with DAC (Twinax) cables.


When using DAC (Direct attached copper, also known as Twinax) cables, you may run into link connectivity issues when not using cr4 auto negotiation. This is resolved by enabling cr4 auto negotiation, which is not enabled by default. The example below shows how to do this on interface 37 on unit 0, and then saves the configuration.

Ftos>enable

Ftos#config

Ftos(config)#interface fortyGigE 0/37

Ftos(config-if-fo-0/37)#intf-type cr4 autoneg

Ftos(config-if-fo-0/37)#end

Ftos#write memory

Note: This command is only applicable on Forty-Gigabit Ethernet interfaces.

To remove the above configuration run the following command in the interface configuration.

Ftos(config-if-fo-0/37)#no intf-type cr4 autoneg
