cisco 3750 LACP problems

Hi all,

I have the above switch (3750) installed.  The problem I have below is based on one of the port groups and not all:

I have an ESX host running Esxi 5.5 setup with 4 nics using NIC teaming based on port id.

On the switch I have 2 ports lets say gi0/1 - 2

Config for each port is:

# switchport mode trunk

# swicthport truck allowed vlan 2-100

# switchport trunk encapsulation dot1q

# spanning tree portfast trunk

# channel-group 1 mode active

Portchannel config:

Interface Port-channel1

# switchport mode trunk

# swicthport truck allowed vlan 2-100

# switchport trunk encapsulation dot1q

# spanning tree portfast trunk

When I run:

# sh protocols (it shows the portchannel down)

and when I run:

# show LACP neighbor (it only shows the uplink port group 12)

I have check the config on the ESX host and it is the same as my other ESX hosts which I must add work correctly.

For the life of me I cannot find the problem and why LACP is not active.

Any help would be great

Have you checked the logs when you connect your switch to the ESX host? If there is a problem, it will usually tell you what's wrong.

If so, have you performed any debugs when connecting it?
