Affecting several VLANS to a Port Group

Hi all!

We have 2 switches farm of server connections to the host server. Each of our 8 ESX servers has 4 physical network adapters that support virtual machines. We have 2 network cards to each physical switch. We have a single vSwitch and 2 port VM groups set up on each ESX Server. We use and configuration active / standby in Port groups so we can control what physical move the VM speaks to. All 4 network cards are available for the Group of ports, with connections going to spend 1 active and forward to switch connections 2. It is reversed on the other group of Port.

We have several VLANS associated with our data center. Is it possible to put the tag VLAN on 2 port groups VM to support multiple VLANs? Otherwise, I think we have to put up a pair of these groups of ports for each VIRTUAL local area network, we want to make it available to the virtual machines on each ESX Server. Is this correct? We have some circuits/EtherChannel enabled on switches that work properly. However, we cannot port VM groups to pass traffic unless label them us, and it seems we can only enter a VIRTUAL local area network in the area.

Thank you in advance for your help!

To use the trunks that are coming in your ESX host, you must have your VLAN Tag somewhere along the way. If you are not at the level of the switch (since you're trunking), you will need to do the vSwitch, either the level of the virtual machine.

VSwitch level, this by creating exchanges and then marking at the level of the port group. Marking that is currently happening in the ESX/vSwitch, and your vm must use the port suitable for group the VLAN they need to use.

Your last option is to tag at the level of the virtual machine itself. To do this, your vSwitch must use VLAN 4095 tag, which allows all the VLANS to pass through, and all tags are marked. The portgroup vSwitch here is basically a tunnel and will allow the unmodified traffic, but now, you have to mark your VLAN of the NETWORK adapter in your virtual machine. It is very effective if you have a large number of virtual machines. The most practical method will be to create the VLAN-based exchanges at the vSwitch level and go from there.

Unlettered, somewhere, communication will not incorrectly, as the physical switch will assume that all traffic not marked will even vlan uses unmarked frames (vlan native), and machines on that vlan can communicate each other.

Get the VLAN of a port group

What is the fastest way PowerCLI, when knowing the name of a virtual machine and that it is on a standard switch, I can find the number of VLAN that the port group it uses is labelled for?

Battery M8024-k (pair) M3048 (pair) battery gal, VLAN and port groups?

Hi all

I'm getting more confused by the minute. I have a pair of M8024-k blade switches in a M1000e enclosure, outside, I have a pair of N3048 switches.

I think I have the job of stacking on the M8024-k, but I found a configuration guide for Simple mode that says take port 17-20 outside the Group of ports on the pair aggregation and leave the stack ports and internally in the PA Group. When I do that they remain outside the group, if I do it in the CLI or the GUI.

Does anyone have a configuration guide that shows how I can pair trunk the 2 together and allow 4 VLAN that I keep coming without access to blade servers inside? What I get out of simple mode on the M8024-k to achieve?

Any help gratefully received.

The best source of information is going to be the user guides.

I would wear the 8024-k off simple mode.

Console# not simple mode

On two batteries, you will need to aggregate 4 ports together. Here is an example to place a port in an aggregation group.

Console (config) # interface gigabitethernet 0/1/5

Console (Config-if-1/0/5) # channel-group mode 1 (active / Auto)

Once the ports are in a channel-group 1, we can then configure the channel group to perform for several VLANs.

Console (config) # interface port-channel 1

trunk mode console (config-if-po1) #switchport

#switchport console (config-if-po1) trunk allowed vlan add 2-150

This is done, you should have connectivity.

Keep us informed.

Port - group VLAN ID Questions

Hi guys
Can I change change the running virtual machine port group?
in the case where the virtual machine was in a group of Port named test - VLAN ID 100 and I need to change the Port Group deployment VLAN ID 105 which now means my VM will not have access to traffic on vlan 100? It's automatically or I need to change my IP or something?
and this comes from the frequently asked questions
Q: a configurable virtual machine on several VLANs?
A: you can set up a single VLAN ID for each virtual network adapter on a virtual machine. However, since you can config -.
ERUS up to four virtual cards per virtual machine, you can configure a virtual machine that spans four different VLAN.
I think I'll need to set up several virtual LANs for some virtual machines. What do mean by "set up a virtual machine that spans four different VLAN".
Thank you guys

Yes, you can certainly change the portgroup. But, remember, your new VLAN is configured properly in order to maintain the networking of virtual machine after the change.

Max on max. position 2-3 drops of ping may occur depending on your use of the network and ESX utlization of resource for the change task.

Simply go to the settings-> virtual adapter - > select new vlan-> OK

If you want your traffic to be moved to a different VLAN dynamically, it must be done at the level of the physical switch. Think of the vswitch as a "dummy" switch layer 2, it will follow policies of networking of the physical switch only, sound rather a passage only. Everything depends on the new port (nic) configured to take the new vlan correctly or not.

VLAN Port groups

Hello
I have more than an esxi host 5, separated by a physical network, I want to configure a VLAN on each host, suppose I want to use three groups of ports each a unique ID vlan on a vSwitch on one of the hosts, I create a port groups and give them an ID vlan. If the connection between the physical NETWORK adapter on the host and the external switch have a specific configuration on the side of the network adapter or on the physical to Miss? because I read about it on many cases on the internet everyone talking about something different.
Please help me

areeb1988 wrote:

But if all the hosts on the same physical switch, can I use trunk connection?

Yes, it does not matter. Note, however, that the "trunk" is what Cisco calls a switchports that sends / accepts frames with tagging VLAN. If you switch to other suppliers 'trunk' name may not be what you must configure.

Change the VLAN ID on a group of ports on a vSS

We are changing the subnet that our vCenter VM resides on that will translate into change us vCenters IP address, subnet mask and gateway.
He also goes to say that we must change the VLAN ID on the port group.
My question is, can we change the Port Group VLAN ID first or first change vCenters details?. (So it is in VST Mode physical ports on the switch are trunk ports with say VLAN 100 and 200 with the new 300 of VLAN to add)
Very welcome any suggetions. :-)

Use the vSphere client to connect to the host that is running the VM vCenter.

In this session of vSphere client, you can

(a) change the VLAN switch vSS

(b) open a console for the VM vCenter and change the IP settings it

The vCenter VM will lose its network connection, but your session will continue to run, because you are connectly directly to a host (and no to vCenter).

If the vCenter server is connected to an Active Directory server, then make sure to use a local administrative account or a domain administrator with cached credentials to connect.

Furthermore, after you change the IP address of vCenter you will probably run the issue described here: http://kb.vmware.com/kb/1001493, but the article contains a resolution for this.

Add Virtual Machine Port Group vSwitch (network and Vlan ID tag) by Script

Hello
I want to add a port group of VM for about 200 guests vSwitch. This can be done manually, but if anyone can help me to do it with the help of Powercli. We have guests organized on the basis of clusters.
Virtual machine port group.
Tag network:-XYZ
VLAN ID: XYZ
Thank you
Pranab

You could do something like that
```
$clusterName = "cluster"
$pgName = "test2"
$vlanId = "1111"
$vSwName = "vSwitch1"

Get-Cluster -Name $clusterName | Get-VMHost | Get-VirtualSwitch -Name $vSwName | New-VirtualPortGroup -Name $pgName -VLanId $vlanId
```
It will add the portgroup to the vSwitch on all hosts in the cluster

PowerConnect 2848 - several VLANS on the 1 port does not

Hello everyone.

I have a Dell PowerConnect 2848. My router is a Netgear SRX5308. In the router, I've created several VLANs (VLAN ID 10 and 20) and would that pass to the ESXi server. If I connect the ESXi server directly to the router, everything works as expected. My VMs are picking up correct VLAN based on the parameters of ESXi.

I need the 2848 between the two, because I need to add more devices and other servers with a VLAN specific.

Currently I use port 25 for switch 2848.

I put the switch to managed mode.

I created switch-> VLAN-> belonging to a VLAN, VLAN ID 10 and 20.

I select 10 VLANS and put the T on port 25.

I select the VLAN 20 and put the T on port 25. (I also tried to put a U on them, just to try, but did not work)

But my virtual computer are not able to reach the DHCP on the router.

Spanning Tree is enabled.

I'm obviously missing something...

I have already passed last week banging my head on this, but have not been able to pass traffic along.

Help, please!

So you're on the right track. If port 25 is facing the router? What port must face the ESXi Server? That port should also have VLAN 10 and 20 should be labelled.

Several physical NIC cards connected to vSwitch / Port Group

Hello
I have several physical NETWORK adapter on a host connected to a single vSwitch / port group, does this mean that the speed of the network is shared by all of the physical NIC, or I have to do something special to enable this feature?
Please see attached .jpg
Thanks in advance.

If all of your network adapters is active in the nic teaming configuration, you must have a physical switch that supports the aggregation of links and you must configure it. The ESX itself does not have this kind of work.

Actually is a bad idea to let all NICs connected without having to configure the nic teaming (1 active and others waiting for failover) or without going through the aggregation of links.

vSphere 4: circuits Multi VLAN on a port (VGT) group.

vSphere 4 allows a group of ports to be configured with multiple VLANs. Previously, a group of ports needed to be configured with 4095 who was an approach all or nothing. Under vSphere 4, I think that a port group can have multiple VLANs specified IE. 453,3454,112 etc.
My question is; This is available on a vNetwork distributed switch or is available with a switch vNetwork Standard?

It is only available with the distributed switch.

1252 config several VLAN trunking on ethernet not

Hi all I am new to these forums, but have read some posts on configurations for an AP from 1252 to switch 2950.

I have several VLANS andmultiple SSID configuration on my ap. The switch knows the VLANS on the access point

I think that in the config.

When I put the 2950 in trunk mode on the port, the ap is conencted too, I can see no longer the access point. And none of my ssid / VLAN traffic through the stem net ether to the switch. I think I have a problem with the config of the ap specifically either in the British Virgin Islands (do not understand this virtual port) or in bridge groups. (Never worked with foredeck groups.)

The AP is in stand-alone mode.

Here is my config on the side of the ap.

51 of VLAN is what I'm trying to trunk more. VLAN 100 is my networks vlan normal almost everything at the moment. And my attempt to secure traffic wireless to a new vlan Vlan 300 more course on my local network.

VLAN 51 has no ip address range

IP VLAN 100 range is 10.131.10.0

10.131.11.0 between 300 VLAN

The routing goes to my switch 3750 core / router, but the access point is conencted to a 2950 namely shared resources to my layer distribution on a stack of 2975. Once again the vlan 300 works on the 2975 stack and will pull dhcp if it is enabled. Have not tried this on the 2950 yet, but I suspect it will also work based on the setting of the trunk on the s950 battery of 2975.

In any case, I want to be able to do is have multiple VLANs configured on the AP (from most secure to least guarantee based on the capabilities of the equipment) and that traffic vlan tag go to my 3750 possibly for other guidelines.

Here, any help would be greatly appreciated.

Thank you for taking the time to read this.

Yes, remove the vlan 51 can tell vlan 100 is the native, and there will be a link to bridge - Group 1. Then change the switch port to vlan 100 native. You should then be able to reach the access point via telnet/GUI.

orders will be:

config t

No int dot11radio0.51

No int dot11radio1.51

No int g0.51

int dot11radio0.100

100 native encapsulation dot1q

int dot11radio1.100

100 native encapsulation dot1q

int g0.100

encapsulation dot1q 100 natively.

To be sure, save reboot and wr mem.

Port-group on newly created vDS does not work

Hello
I have 4 hosts ESXi with version 5.1. The VCenter had the same version 5.1 but the server crashed a few months back, and reinstalled the VCenter engineer new version 5.5 U2. I also have virtual Distributed Switch configured with several groups of ports (VLAN). VLANS are separated by the ID VLAN different. All virtual machines with their VLAN respective can communicate to the breast even VLAN, but also the other VLANs.
However, I just created a new group of Port with different VLAN ID. Now, the virtual machines in this new VLAN cannot communicate themselves as well as other VLANs. From the virtual machines ping response say "Destination host" inaccessible
When I move the virtual machines to another VLAN they start working and when I move them back to this new VLAN they do not.
I also tried assigning VLAN IDS to another VLAN to this group of port newly created, beginning of VMs works again. But the VLAN ID of this group of ports does not work with other groups of Port.
To me, it seems that the creation of new VLAN ID has some problems. Although I followed the documented process of VMWare.
I noticed that I have the following versions:
1 VCenter Server: worm 5.5
2 Server ESXI host: ver 5.1
3 vDisbritued Switch: ver 5.0
Have idea if it's a bug or compatibility problems. Am I missing something?
Thank you

Add the new port group to dSwitch

Hello
Given that I have never done this and this prod, as I decided to ask first ;-)
In ESXi 4.1 using a dSwitch, if I add a NEW port group using a VLAN that is not in use (on this dSwitch), that will force any failure to migrate it virtual machines on this dSwitch?
Adding this new group of port causes the dSwitch "reset" in a manner that will cause the failure?

You should be able to add, modify and/or delete groups of ports without affecting other groups/VMs port connected to other port groups. Just follow the steps in http://kb.vmware.com/kb/1010593
