Cisco Port Configuration for NIC Teaming

I'm going to setup NIC teaming on one of my servers.  I am going to install a intel 4 port NIC card in this server.  I want to use ports fa0/45, fa0/46, fa0/47, and fa0/48 on my Cisco 3550 switch.   I've looked over several documents from Cisco, but I'm still a little unsure.  I'm hoping someone can provide me with the configurations I will need for these four ports.  Below is the current configuration of my switch.  Thanks.

Thanks, I'll give this a try.  Will this work regardless of the type of 4 port NIC I am using?
0
 
Ernie BeekExpertCommented:
That shouldn't matter. Though some type's have better teaming software than others.

Does the "spanning-tree portfast trunk" have to be in the config?  Could this cause loops?
0
 
Craig BeckConnect With a Mentor Commented:
spanning-tree portfast trunk is a command used when 802.1q capable NICs are connected to a switch.  Under normal circumstances you don't want portfast on trunk ports (typically for switch interconnects).  This option just tells the switch that the port should come up straight away.

No loop condition will occur if you configure your NIC teaming correctly.  Some teaming software may use different terminology, but you should use LACP (or 802.3ad) if you can.

As a note, I would probably change the line crossroads included above, as it implies a PAgP device (which is Cisco Proprietary)

channel-group 1 mode desirable
could be...

channel-group 1 mode passive

...which will enable LACP on the ports if an LACP device is detected.

Ernie BeekExpertCommented:
Nope. That means that (for example) when you reboot the server, the ports on the switch won't be put in hold-down but start forwarding immediately. You always add that when a computer/server is plugged in to a switchport and never add that when another switch or router is plugged in.

I ended up using
channel-group 1 mode passive
