Private Vlan support on CAT3850

dmitry

Level 1

Hello , i need to configure private vlans on Catalyst 3850 .

On this page is said that 3850 does support this technology

http://www.cisco.com/en/US/prod/collateral/switches/ps5718/ps12686/qa_c67-722110.html

But i can't  configure it because there is no such commands in CLI

3850(config-vlan)#pri?

% Unrecognized command

Does it support it or will it support private vlans in future?

There does seem to be conflicting information. The link you provide does say they are supported but looking at the config guide it says -

Restrictions for VLANs

The following are restrictions for VLANs:

  • The switch supports per-VLAN spanning-tree plus (PVST+) or rapid PVST+ with a maximum of 128 spanning-tree instances. One spanning-tree instance is allowed per VLAN.
  • The switch supports IEEE 802.1Q trunking methods for sending VLAN traffic over Ethernet ports.
  • Configuring an interface VLAN router's MAC address is not supported. The interface VLAN already has an MAC address assigned by default.
  • Private VLANs are not supported on the switch.
  • You cannot have a switch stack containing a mix of Catalyst 3850 and Catalyst 3650 switches.

So it looks like with this release at least, they are not available. I don't know whether they are scheduled to be included in a later release of the software.

Perhaps someone from Cisco can comment. The product page certainly needs updating as it seems the configuration guide is the correct one.

Edit - i have posted a link to this thread in the Technical Documentation forum to ask for clarification although a Cisco person is still not guaranteed to answer.
