I am trying to establish a 1 Gb link between a C3 switch and a Cisco router ASR1001.
Until now the highest speed obtained is 100 Mb FD.
The cabling in between is brand new certified cat6.A
Patch cables idem dito.
Distance is about 60 meters.
Connecting a PC wit Gigabit NIC over the cabling is working on both systems Cisco or C3 switch.
On the C3 I advertize 1000TFD. Enabling or disabling negotiation is not solving the issu.
Any help is welcome.
