Private VLAN and EtherChannel.

andrea.meconi · ‎06-04-2010

I'm using a 3750-E and I need to configure a bundle of four GbE to connect a server. How can I do this? From configuration guide PagP and LACP are not supported.

Many thanks for help.

Regards.

Hi,

Below is the link to configure Etherchannel on 3750 for code 12.2.44SE:

Many thanks for your help.

I need to bundle a set of four isolated pvlan ports to build a channel configuration.

my apologies as was thinking that it was generic Etherchannel configuration

Cisco states that there is no etherchannel support for the ports which are configured for Private Vlan. It is advised by cisco to see the limitations before implementing this feature.

Don't worry.

This is a new request to bundle isolated pvlan ports!

You cannot create an etherchannel with a private-vlan host-association..

However, depending on the IOS of the 3750, you should able to perform a "SWITCHPORT PROTECTED" on the port-channel interface OR limit it with a VACL.. Either way would probably impact the architecture of your environment.

On a side note.. One way to get around this restriction is implement a vSphere Distributed Switch and use VMware hosts.. The vDS DOES support Cisco private-vlans. I created an etherchannel Dot1q trunk & trunked private-vlans to the vDS. The vDS can then distribute them to the VM hosts..

Just my 2cents..
