Spanning tree problem in Etherchannel in cisco 6006 switch

Hai all,

We have made fast etherchannel in Cisco 6006 switch's copper ports for increasing bandwidth to the servers. In the servers side, teaming is done by a utility given by Intelpro. When we test the switch configuration in the servers, a problem is stated as the ports in etherchannel are in spanning-tree forwarding state. The solution is given as disable STP on the switch. Since the switch is core switch connected to a mesh network, disabling STP on the switch will cause problems like Spanning tree loops.

We have enabled portfast on all the etherchannel ports. Still we are facing the same problem. Is there any exact procedure to be followed for forming etherchannel with teaming in other side. what can i do to solve this problem.

Suggestions are appreciated.

What operating system is this? What is the module type on the 6k side? What is the 6k code ver? Here is the Intel link that spells out which modes are compatible with Cisco switches.

Here are channel configuration guidelines for 6k.

Post your 6k channel config and tell us which teaming mode and features you are configuring on your server.

Re: Spanning tree problem in Etherchannel in cisco 6006 switch

Dear tsettle,

Thanks for your information.We have configured fastether channel in the cisco 6006 switch. The operating system used is Windows 2000 Advanced server. Cisco 6006 switch 10/100BaseTX Copper ports are used for etherchannel and the Image is CATOS ver 6.1.

There is no information in the intel article regarding the support switches. Will this switch with CatOS 6.1 ver support Etherchannel?

Thanks in advance.
