Private Vlans ,Cisco 3750 and ESXi

[j44mistry]

Has anyone worked with private vlans on ESXi Vmware trunked to a Cisco 3750 switch also using private vlans?

ESXi-->Cisco 3750-->Firewall ->Internet

Is this supported ?

Hello

I can honestly say I have not - but I guess once in the switch the features are applicable

What is it you wish to know -I assume does it work?

Hi Paul,

I have private vlans configured on both but cannot ping default gateway which is firewall.

Hi,

If you have multiple primary vlans configured, the connection to the firewall needs to be configured as trunk.

see config guide below:

I have 2 x 3750 Switches in a stacked configuration (see diagram and config)

The uplink to Internet firewall is a active/backuplink using normal switch port.  

The link to the LAN Firewall is the only one trunked.

There is a proxy Server which is needed to get to internet this is connected to cisco switch port 1/0/5 which is also on Vlan 255 , does it need a private vlan ?

Cant ping default gateway 192.168.255.101

I know is stupid and late, but are your Firewall pingable?

I'm going through the same issue.
