Re: Cannot Establish Gigabit Link Between Catalyst Switches and
The flow control settings must match on both sides for the link to come up. It is highly recommended that you configure auto-negotiation to on for both devices. (Auto-negotiation is enabled by default on all Catalyst switches.) Otherwise, if you have a layer 1 problem, the link remains up and a unidirectional link will result.
The initial software releases that support Gigabit Ethernet on the GSR router do not support gigabit auto-negotiation.
The following command configures gigabit auto-negotiation on the Catalyst 6000/6500:
We are pleased to announce availability of Beta software for 16.6.3. 16.6.3 will be the second rebuild on the 16.6 release train targeted towards Catalyst 9500/9400/9300/3850/3650 switching platforms. We are looking for early feedback from custome...
