7750 Link Aggregation problem

I am trying to set up link aggregation with load sharing. Every group I set up always shows it is set for NonS. Does any one know how to config this? Do you need the links connected before is will change the status? I have followed the instructions in the configuration guide and have even set up the ports with lacp enabled.



thank you,

Re: 7750 Link Aggregation problem

Try to view the interface attributes. To achieve loadsharing the member ports of the link aggregation must have the same attributes; this is SPEED, DUPLEX (full) and generic stting such as STP, VLAN, GVRP, QoS and VLAN-vpn configurations.

Re: 7750 Link Aggregation problem

Thank you for replying. I had a vendor set this up but he has not had time to get it to work I thought I would thy to find out my self. I am going to support it any way.



Here is what I can find on the ports. It looks all the same. Is it possible that when I hook up the server to it the status will change?

both ports are on vlan 1 untaged.

Update, I go it working. It was not the switch settings but found a bad cable in the system not letting the port come up speed.



Thank you again for you help.
