C3925E query on gigabit Ethernet port - "negotiation auto"

[Nilesh Jaltare]

Hi,

Kindly confirm if "negotiation auto" is supported gigabit port for C3925E router.

Router(config-if)#Interface gi0/2

Router(config-if)#description test link

Router(config-if)# no ip address

Router(config-if)# negotiation auto

                    ^

% Invalid input detected at '^' marker.

Thanks in advance

That is 'speed auto', and 'duplex auto'.

[Nilesh Jaltare]

Can we hardcode or for this platform, this is the only way around?

Regds,

Hi,

Do you want to hardcode you router port speed and duplex settings?

You've probably mixed up the idea of DTP on a switch.

You can hardcode duples and speed as desired.

he automatic negotiation mode is enabled by default. Some early Gigabit Ethernet products that predate the IEEE 802.3z standard might not support the automatic negotiation process or have problems establishing a connection. In these cases, the link is established by disabling the auto negotiation mode. GEIP allows the automatic negotiation process to be re-enabled by the negotiation auto command or bypassed by issuing the no negotiation auto command.

negotiation auto
no negotiation auto

IEEE 802.3z  is not support on c3925e .chack below
