Trunking Between Cisco 3750 & SGI 350 Series Server

Hi,

If the SGI server NIC supports 802.1q trunking, then simply enable it on the server, and then configure trunking on the 3750. It should look something like this:

!

interface GigabitEthernet1/0/1

switchport access vlan 1

switchport trunk encapsulation dot1q

switchport mode trunk

end

!

This enabled 802.1q trunking in mode "on" with a native vlan of 1. mode "on" disables DTP negotiation, which is proprietary to Cisco, and will not work with the SGI server. As long as the SGI server NIC supports dot1q, that should work.

Hope that helps. Please rate helpful posts.

thanks,

Bobby

Hi,

my setup will be like.... SGI will have 2 NIC, both the NIC will have the same subnet IP address. so with this trunking or etherchannel on cisco 3750 will it work?

purpose of having this setup is, to share the network load. also even if 1 NIC fails, it should still be in a position to send the data in another NIC.

trunking and etherchannel will work, _IF_ the NIC supports it. The NIC will need to support 802.1q for trunking to work, and some sort of NIC teaming or 802.3ad for etherchannel to work.

If these conditions are met, then yes, you can configure the two nics as a trunked etherchannel that will provide both redundancy and aggregated bandwidth.

Hope that helps, please rate helpful posts.
