SG500 VLAN, 802.1q and Vmware Setup Problem

[Roger1000]

I'm trying to setup an SG500 28 switch for a Vmware 5 environment with multiple VLANs.  I'm having difficulty undertanding how to configure a supported trunk for the VLAN routing that supports Vmware's need for a 802.1q trunk.  Typically I would use the following commands on a cisco switch but this unit does not support all the commands.

Is there a way to specifically achieve the switchport encapsulation dot1q setting in any other way on this switch (SG500-28)?? 

*** I'm really looking to configure a supported trunk for this build because I can not communicate within VLAN's and within VLAN's for my virtual hosts.

This is a Cisco Switch  port TRUNK sample configuration.

Apply the following  commands to Cisco Switch command line:

• interface  GigabitEthernet1/1
• description VMware ESX - Trunk A - NIC 0 – Port Description
• switchport trunk encapsulation  dot1q – ESX only supports dot1q and not ISL
• switchport trunk allowed vlan 100,200 –  Allowed VLANs
• switchport mode trunk – Enables  Trunk
• switchport nonegotiate – ESX/ESXi does  not support DTP dynamic trunking protocol. When configuring trunk port, set it  to nonegotiate.
• spanning-tree portfast trunk – Enables  PortFast on the interface when it is in trunk mode.

Thanks,

Roger

Hello Roger, try the following;

config t

int gi1/1

no macro auto smartport <- disable smart port for detecting link

switchport mode general <- sets port to 802.1 q

switchport general ingress-filter disable <- removes filtering of vlan tag for the ingress

switchport general allowed vlan add 100,200 tagged  (or untagged, however you need it) <- allowed the vlan on the port

spanning-tree portfast <- enables port fast

On my switch it does not have the "switchport mode general" or "switchport trunk encapsulation dot1q" - I get an error (you know, the ol' invalid command or syntax with the little marker).  The switches are catalyst WS-C2960-24TC-L with the Cisco LAN Base software.  They are less than 3 years old.  I hope this means that the encapsulation is set to 802.1Q by default.  Does anyone know for sure, or how I can tell?  Many thanks!
