switchport config for Eucalyptus cloud

I am currently trying to configure a Cisco 3560G running IOS for use as an access switch with Morph's KVM cloud offering. The documentation states I should allow vlan tagging for segregation of client traffic, but keep one vlan untagged for host traffic. I setup our switchports as follows:

int rang g0/17-32
switchport trunk encap dot1q
switchport trunk native vlan 3000
switchport trunk allow vlan 3000-3400
switchport mode trun

The OS on the host is CentOS running with /lib/modules/2.6.18-194.el5/kernel/net/bridge/netfilter/ebt_vlan.ko loaded. The vlan interfaces are unconfigured as of now.

Shouldn't I be able to ping the untagged ports? When I do a "sh mac-add" on the switch, those ports show no mac addresses. What am I doing wrong/what is the magic trick?

You won't be able to ping untagged ports from your network because I'm assuming your other ports are not in vlan 3000.

If you haven't already you can allow the switch to communicate between vlans with the ip routing global command. You'll need to setup the vlan interface as well.

Let me know if that helps

Actually, the issue was that I had "vlan dot1q tag native" in the global config. Once I removed that, I was able to communicate with all the ports.

Thanks to those who responded.
