3750 Bond to Ports?

[bleucube]

I would like to bond/team 2 ports on my 3750. This is what I current have:

interface Gigabitethernet4/0/21

description "Team Member 1"

Switchport mode access

no ip address

no mdix auto

channel-group 9 mode active

spanning-tree portfast

interface Gigabitethernet4/0/22

description "Team Member 2"

Switchport mode access

no ip address

no mdix auto

channel-group 9 mode active

spanning-tree portfast

Not working tho... any help appreciated. Thanks!

Answer was:

Anyhow follow this config as it is and it should solve the issue.

Sw(config) # interface Port-channel9

Sw(config-if)#no description Brain5 Team

Sw(config-if)#no switchport trunk encapsulation dot1q

Sw(config-if)#no switchport mode access

Sw(config)# no interface Port-channel9

Sw(config)#default interface range gi 4/0/21 -22

===========================================

SW(config)#interface range gigabitethernet 4/0/21-22

SW(config-if-range)#switchport mode access

SW(config-if-range)#channel-group 9 mode on

========================================

sw(config)#int port-channel 9

sw (config-if)#no ip address

sw(config-if)#speed full

sw(config-if)#duplex full

end

============================================

I try doing that on a cross-stack on 3750Gs and it does not allow me to use "switchport mode access". I have to use a trunk and it works good for LACP

no issues with the configuration

check with the teamed adaptors , does your nics support LACP ?

[robertg1234]

Most host/server nicteaming does not support LACP (or any other etherchannel linking protocol) except for a very few servers (the Dell 1655 comes to mind -- except it's really a Dell managed switch built into the multi-blade server). Most ppl will refer to nicteaming as a HSRP-like backup/failover setup. The NIC mfgr utility will usually show the nicteaming capabilities. This is Windows, of course.

Linux has no such problems :)

Anyway, turning off any aggregation protocol will usually work.
