Pvlan trunk on CBS31X0 switch

Hello, I need to configure a pvlan trunk on DELL enclosure with Cisco Blade Switch, to permit pvlan and a normal Vlan.

My version is

Cisco IOS Software, CBS31X0 Software (CBS31X0-UNIVERSAL-M), Version 12.2(55)SE, RELEASE SOFTWARE (fc2)

But, when I want to enter "Trunk" on private vlan mode, I can´t, because only has "host" and "prominiscous" mode.

DBUEPACDC-1(config-if)#switchport mode private-vlan ?

  host              Set the mode to private-vlan host

  promiscuous  Set the mode to private-vlan promiscuous

Any idea?

Thanks in advance!

Regards

Hi,

You only trunk the uplink and not the interface connecting to the end devices:

have a look at this doc for examples:

Hi Reza, thanks for reply. Yes, trunk apply to Uplink switches, but in this case, I need trunk the port connected to server. This server (HP Blade) will tag all the packets.

Thank you!

Hi Manuel,

Then in that case the vlans need to be isolated.

From the config guide:

Private VLAN Trunk Port

A PVLAN trunk port can carry multiple secondary (isolated only) and  non-PVLANs. Packets are received and transmitted with secondary or  regular VLAN tags on the PVLAN trunk ports.

Note Only IEEE 802.1q encapsulation is supported.

Here is the config guide:
