Creating an etherchannel to an HP Windows Server

This will very briefly describe how to setup a port-channel connection between a Cisco switch and an HP server.

*Note - HP Server, Discovered Bug (Must manually set speed to 1000 and duplex to full on server for proper operation.)

On the server, set teaming to 802.3ad Dynamic with Fault Tolerance (team will fail until switch is configured)

Configure interfaces with port commands shown on interface below

6509#sh run int gi2/25

interface GigabitEthernet2/25

switchport trunk encapsulation dot1q

switchport mode trunk

switchport nonegotiate

spanning-tree portfast trunk

channel-group 100 mode active

Configure port-channel with commands shown on interface below

6509#sh run int po 100

interface Port-channel100

description ServerPO

switchport trunk encapsulation dot1q

switchport mode trunk

switchport nonegotiate

mls qos trust dscp

View port-channel status
