Cisco Switching/Routing :: ME 4900 Private VLAN Config
Feb 9, 2012We need to connect several DSLAMs on the 4900 switch, every DSLAM has 4 VLANs configured (VOIP service, MGMT, ADSL Private, ADSL Public), and sends the traffic for each service tagged with appropriate VLAN id according to the table:
VOIP: 608
MGMT: 594
ADSL PRIVATE: 2900
ADSL PUBLIC: 2930
On the DSLAM side it is very simple configuration, just a normal trunk with 4 VLANs transversing the link. On the 4900 I need to isolate the traffic for ADSL PRIVATE & PUBLIC service so DSLAMs connected to the same switch do not have L2 connectivity between them. For VOIP and MGMT they must communicate with each other. DSLAM acts also as a VOIP GW so it must communicate with other DSLAMs for VOIP service. Also VLAN 200 is configured on ME 4900 for switch management traffic.
This 4900 Switch connects to MPLS PE router, which offers L3 VPN service for VOIP & MGMT service, and L2 VPN for ADSL service (PPPoE traffic to BRAS). Fortunately we have ES+ linecard to support many ethernet features. I tried this config:
1) VOIP, DSLAM-MGMT, MPLS-MGMT configured as normal VLANs
2) ADSL PUBLIC & PRIVATE configured as isolated secondary VLANs, primary VLAN for ADSL PRIVATE is 2008, for PUBLIC 2308
3) Configure DSLAM facing ports on ME 4900 as private-vlan trunks
4) Configure ME 4900 uplink port to MPLS PE as a private-vlan promiscous trunk
5) Configure ethernet services on MPLS PE for each tag that comes from ME 4900 (ES+ cards are awesome, i love them:D )
6) Apply L3 VPN service for VOIP and DSLAM-MGMT, and L2 VPN for ADSL service.
But at least this last command should list on spanning tree forwarding state also the ADSL VLANs or not?
Here is the output of the show interface switchport.

Dec 29, 2011I have the need for private vlans in isolated mode to backup some hosts on a secured network. We are using Cisco Nexus 5020 with the fex 2148 for copper-ports - and I tried to implement this setup: [code]
The Cisco Nexus 2000 Fabric Extender does not support PVLANs over VLAN trunks used to connect to another switch. The PVLAN trunks are only used on inter-switch links but the FEX ports are only meant to connect to servers. Since it is not a valid configuration to have an isolated secondary VLAN as part of a Fabric Extender port configured as a VLAN trunk, all frames on isolated secondary VLANs are pruned from going out to a FEX.
the "only" limitation should be the trunk option - but as far as I can see from the output from my nexus this is not correct .We are running NXOS: [code]

Cisco Switching/Routing :: Private Vlan / Etherchannel And Isolated Trunk On Nexus 5010
Feb 9, 2011I'm not sure if I'm missing something basic here however i though that I'd ask the question. I recieved a request from a client who is trying to seperate traffic out of a IBM P780 - one set of VIO servers/clients (Prod) is tagged with vlan x going out LAG 1 and another set of VIO server/clients (Test) is tagged with vlan y and z going out LAG 2. The problem is that the management subnet for these devices is on one subnet.
The infrastructure is the host device is trunked via LACP etherchannel to Nexus 2148TP(5010) which than connects to the distribution layer being a Catalyst 6504 VSS. I have tried many things today, however I feel that the correct solution to get this working is to use an Isolated trunk (as the host device does not have private vlan functionality) even though there is no requirement for hosts to be segregated. I have configured:
1. Private vlan mapping on the SVI;
2. Primary vlan and association, and isolated vlan on Distribution (6504 VSS) and Access Layer (5010/2148)
3. All Vlans are trunked between switches
4. Private vlan isolated trunk and host mappings on the port-channel interface to the host (P780).
I haven't had any luck. What I am seeing is as soon as I configure the Primary vlan on the Nexus 5010 (v5.2) (vlan y | private-vlan primary), this vlan (y) does not forward on any trunk on the Nexus 5010 switch, even without any other private vlan configuration. I believe this may be the cause to most of the issues I am having. Has any one else experienced this behaviour. Also, I haven't had a lot of experience with Private Vlans so I might be missing some fundamentals with this configuration.
Cisco Switching/Routing :: 2950 - Private VLAN Across Trunk To Older Model Switches
Mar 7, 2012I am looking into the possibility of using private vlan's for some dmz implementations however I do have what may be some very rudimentary questions. It seems straightforward how to configure the primary/secondary vlan configuration as well as associating them. However in my case I would be looking to configure the PVLAN on a 6500-vss platform acting as the router while all of the hosts which I would desire to have in the isolated vlan would be spread out across a number of older Cisco switches which only support "protected port" setup or Procurve switches all of which I do not have budget to replace with something newer. So in my scenario I would have a 6500 connected by trunk to multiple switches which only support a protected port setup such as a Procurve (top of rack) or a Cisco 2950. As the Procurve or 2950 would not support Private VLAN setup, do I then just configure the secondary vlan to be allowed across the trunk from the 6500, configure that vlan on the Procurve or 2950 (as vtp will not foward the info for the secondary vlan) and assign that vlan to the host port as well as setting it as a protected port and this will communicate just fine across the trunk to the router as well as stopping the protected port in top of rack switch 1 from being able to communicate to a protected port in top of rack 2,3,etc? If the above scenario is what needs to be done, do I just use a regular trunk or do I have to use a PVLAN trunk?
View 2 Replies View RelatedCisco Switching/Routing :: 3750x And Private VLANs
Sep 5, 2012Is this supported on a 3750X ?? A router has two VRFs and its lan interface is a trunk with 2 VLAN IDs, let say VLAN 10 and VLAN 20. The ip address subnet of these two vlans is the same (therefore , they are in different VRFs)
fa0/1
VLAN 10 = 10.15.4.9 (VRF A)
VLAN 20 = 10.15.4.10 (VRF B)
This router is connected on a 3750X switch. There is a firewall connected to this switch also, which is default gateway for several VLANs including VLAN 10 (10.15.4.1)
The goal is that VRF B ip can talk to 10.15.4.1 and VRF A can talk to 10.15.4.1 but VRF B can't talk to VRF A (10.15.4.9 <-> 10.15.4.10)
FW |--- TRUNK VLANs 1,2,3,4,10 ---------| SWITCH |----- TRUNK VLAN 10,20 -----| ROUTER (vlan 10 = VRF A, vlan 20 = VRF B)
I think this is not supported on the C3750, as my promiscuous port is located on a trunk.

I would like to extend the SITE A VLAN to SITE B so that I can move hosts from SITE A to SITE B without needing to change their IP address but the vlan ID is already in use. Obviously the easy solution is to change the VLAN ID for one or other of the sites but both sites contain hosts that run 24/7. Is there a way to join two VLANs with different IDs together.So for example I create a new VLAN 60 at SITE B and associate it with VLAN 50 at SITE A.

I followed the case study 11.4 from [URL] and configured the l2tp-class and pseudowire-class. However, the vlan interface configuration is different on 890 router.
I configured a vlan interface as follows.

#switchport access vlan 200
(config)# interface vlan 200
I don't see the 'xconnect' command in this context. What's wrong with my configuration?

switch 1 provision ws-c3750g-12sswitch 2 provision ws-c3750g-24tsswitch 3 provision ws-c3750g-24tsswitch 4 provision ws-c3750x-48
And we have following error message in the log from the switch:

Cisco Switching/Routing :: Nexus 1000v Don't Use Private VLANs
Aug 28, 2012We have a requirement for private VLANS for DMZ hosting within one of our datacentres. I just want to query how private VLANs would work in our environment.We have physical servers connected to fex ports (2 fex per rack for each 5k) of a 5548UP switch, virtual servers using the nexus 1000v (vmware hosts connected to fex ports) Out firewalls and load balancers are connected to an upstream pair of nexus 7ks using vPCs.My question is this, ordinarily the firewall would be in a promiscuous port but as these reside on a physically separate switch will the normal vPC trunk still be sufficient or would the "switchport mode private-vlan trunk promiscuous" be required on the vPC up to the northbound 7k.As these connections are already in production I do not want to affect the existing traffic that doesn’t use private VLANs.

I have a server running windows server 2008 with a couple of virtual machines running in Hyper-V. I created 4 VLANS listed below and gave the 3750 the following IP Address.I would like the 3750 to only be configurable from VLAN 40 but currently every VLAN can connect to it, I noticed in the standard web page settings there was a setting for "Management VLAN" but it was set to 1 and would not let me change it, I kinda assumed that was for the management port in the back.-Now the tricky part, I was trying to set up routing between the VLANs and so far I have only been able to get a sort of "all or nothing" routing to work. I can turn IP routing on and add two or more VLANs to the routing and it works fine. But what I was hoping to do is create a couple of "junction vlans" that would only route to one or two other vlans. For instance, I wanted to create a VLAN 100 that routed to VLAN 20 and 30 but nothing else. I also want to route VLAN 1 just to VLAN 30, and so on. I am able to do each one of the cases but only one, it seems like the switch only supports one "routing table" am I missing something or is this just a limitation of the switch?
