Internal Switch DHCP

Hi
I have a host machine Server 2012 R2 with AD, DHCP and DNS plus the hyper v role. I have made a Win 8.1 VM. I have set up and internal switch and want the VM to get and DHCP address from the host. Both host and vm are connected to the internal
switch and I have enabled VLAN id. I have binded the dhcp server on the host to the internal swtich/apaters. Is this possible to do as I can only get a 169 address on the VM ?
Thanks

Hi
I have a host machine (Sever 2012 R2) and I have installed a VM (Win 8.1) The host has AD, DNS and DHCP as well as Hyper V Role. I have set up an internal switch and connected both virtual interfaces to it - host and VM. The VM does not get
a DHCP address from the host. Satic IP's work fine. Can this be done - host supply VM with an DHCP address ?
Thanks

CP-6941 detailed rebooting process vs internal switch behavior

Hi all,
We got problem with phone rebooting and its network cutting during phone rebooting time.
We got that scheme:
Access sw with PoE---CP-6941---VDI monoblock under Citrix.
When user logs into an AD with his credentials the phone goes to rebooting cycle cutting for that period monoblock out of a network using its internal switch.
When phone boots up monoblock can get the network.
Does anb know the step by step booting process of a phone and its internal switch behavior during that period?

Switch / DHCP issue

Hey guys - just would like to know what is happening here:
Brand new Linksys switch(SLM2048)- default settings. Connected to DHCP server via other Cisco switches.
Plug in 6 laptops directly into the switch - "unable to find DHCP server".
At the same time
Plug in 6x other laptops into a Netgear 8port gigabit ethernet switch and then into the Linksys switch - "DHCP server found".
Other points to note: There is another brand new Linksys switch(SLM2048) connected to the LAN. (And both are at default settings). After the I changed the default ip of one of the switches to DHCP it all worked fine when plugged directly into the first switch.
Yes I have A solution - But not THE solution??
Why is it by adding another switch to the link it works. Why does adding that switch negate the need to change the default IP on the second Linksys switch on the network.
Any ideas would be appreciated.. (hope I have explained this OK and not confused anyone)
Cheers
James

odd problem that you got there. i just setup the same switch a week ago but i did not encounter this. try to flash the firmware and reset the device and see if that helps.

Linux guest does not get DHCP offer through a bridged internal switch, but Windows guests do (laptop).

I also got trouble getting networking to work on my laptop. It has one Gigabit LAN and one wireless network interface.
I cannot get my Linux guests, I tried CentOS 6.4, Ubuntu 13.10 and Debian 6, to get a DHCP offer from my DHCP server on my physical LAN. Manual configuration using static IP addresses works, but I need DHCP for my laptop.
I tried a Windows 8.1 Pro 64bit guest and the Windows Phone SDK 8.0 and both connected fine to the internet.
Here is what I tried:
With the ethernet cable disconnected I was connected to my wireless network or LAN with WPA2 personal authentication. On this physical LAN there was a DHCP server.
I created an internal Hyper-V switch and then I created a bridge between this switch and my wireless interface. I always used this switch as the single network connection for my VMs.
I am using Windows 8.1 Professional 64bit.
Why are only Linux guests affected and is there a solution? Thank you.

Hi faustbusserl,
"I cannot get my Linux guests, I tried CentOS 6.4, Ubuntu 13.10 and Debian 6, to get a DHCP offer from my DHCP server on my physical LAN. Manual configuration using static IP addresses works, but I need DHCP for my laptop."
Does it mean that you have created an external virtual switch for Linux guests and they can not get IP from DHCP ?
Did you try to use legacy network card for the linux VM to get IP from DHCP .

Ping and Hyper-V virtual internal switch

Whenever I create a Hyper-V virtual switch (internal), ping binds to the IP address of the internal network switch instead of the IP address assigned to physical adapter. How do I prevent this from happening?

This has to do with network binding.
You can change the network bindings using the following steps
You must be logged on as an administrator to perform these steps.
Open Network Connections by clicking the Start button ,
and then clicking Control Panel. In the search box, typeadapter,
and then, under Network and Sharing Center, click View network connections.
Press the Alt key, click Advanced, and then click Advanced
Settings. If you're prompted
for an administrator password or confirmation, type the password or provide confirmation.
Click the Adapters and Bindings tab, and then, under Connections,
click the connection you want to modify.
Under Bindings for‌ connection name, select the protocol that you want to move up or down
in the list, click the up or down arrow button ( or ),
and then click OK.

Internal and external switches on server 2012 r2

this is driving me nuts.
I have a vm with an internal and external switch.
I am trying to get backups to route to the host machine using the internal switch only.
I've gone all over priorities and the routes are all fine but the data will constantly go over the external switch.
If i disable external switch traffic goes over internal switch just fine.
I've read about the automatic detection of least cost routing on the internal switch but just can not get it to run correctly.
please help

881w router to distribute DHCP to switch

I have a 881w router with static wan ip ssetup on fastethernet 4 and vlan1 distributes ip from fastethernet 0. It works fine when I plug a PC directly to fastethernet 0, address is assigned and internet access is connected, the problem is when I connect the fastethernet 0 to a switch no ips are distibuted and even static routing a PC connected to the switch gets no connection.

APs unable to receive IP address from DHCP (core 6500 series switch)

Dear Friends,
a week ago I had stable wireless network APs were getting IPS from 6500 series switch (DHCP) but unfortunately some WISM got rebooted and now APs are unable to receive IP address from Core 6500 DHCP, to cater this issue I have another DHCP server configured on windows 2008 i created another subnet and and put APs in that vlan now all APs are are successfully receiving IPS from windows DHCP server I don't know why APs are not able to receive IPs from core 6500 series DHCP.
please advice

Fortinet 100D - split switch ports into external and internal VLANs?

I'm building out a small colocation site of two hosts.Would like to minimize the number of boxes that I have to buy and manage, but also need to have a reasonable firewall setup. I will have one firewall box and in an ideal world would like to get away without buying one or more switches to put alongside it.My bandwidth provider is going to give me two physical drops that provide connectivity to two of their aggregation routers configured HSRP. If I was going to connect to this in a typical setup, I'd have an external switch with the two drops attached plus one to the external side of my firewall. I'd then connect the internal side of my firewall to my internal switch, and my hosts to that.Given the low port count vs the large number of ports on the Fortinet 100D, I'm wondering if I can split the ports on the box into two groups and be...

Can't get internal vSwitch to route through external vSwitch to connect to Internet using one NIC on 2012 R2 Datacenter with Hyper-V

I'm running into a bit of a problem here.
I have the following two virtual switches setup on one 2012 R2 Datacenter Physical Host w/ one (1) physical NIC:
Physical Host is running 192.168.50.120, GW: 192.168.50.1, SM: 255.255.255.0 (Cisco Router has the IP of 192.168.50.1). The Internal vSwitch Network (will contain 8 VM Servers) is 192.168.1.1. I want the VM Servers on 192.168.1.1 to be able to get Windows
Updates by being able to route through the 192.168.50.1 vSwitch but yet, still want the Networks segregated.
Both of these virtual switches/networks will be running through one NIC.
I initially setup RRAS to use NAT but I'm not sure if this is the correct configuration. It seemed to work but when I went to Activate my Product Key (via MSDN Subscription) it wouldn't recognize the key and therefore I couldn't run windows updates.
However, when I set up two of the VMs on 192.168.1.1 to use DHCP through the 192.168.50.1 Network it would work fine (i.e. DHCP, DNS and GW were all set to 192.168.50.1).
Any ideas on what I might be doing wrong or how I could setup an effective route between the two networks?
Any and all ideas are most welcome and appreciated.
Sincerely,
Wallace

Hi nbk5533,
The external virtual switch and internal virtual are isolated, you must set RRAS to connect both network zone, you can refer the following article to connect the internal
switch and external virtual switch.

Assigning DHCP IP address by SSID

Hello,
I want to assign IP addreses by SSID on the 861W. I have two Vlans on the router on two different subnets, and one DHCP pool for each subnet. On the AP I have two SSIDs on each of the Vlans.
However, when I associate with the different SSIDs, I get an ip address from the same DHCP pool, instead of different pools. I want ip from different subnets with different SSIDs.
Any help is greatly appreciated.

Thanks for the suggestion. However, when I implement these commands clients on SSID Voices (Vlan2) cannot connect to the DHCP server on the router.
Here is my config on the router:

Clients not getting DHCP from external server

Hi,
I have a 4402 (version 7.0.235) working with 10 units of 1121 APs connected to it. The WLC is not configured to work in LAG mode. Physical portt #1 is connected to the Main Switch (trunk). I have 3 WLAN mapped to 3 Different VLAN and Everything (security and internal, external DHCP) is working swell...
Now- I have connected Physical port #2 directly to an ADSL Router (giga port), Configured Port 2 as untaggedwith the proper IP details.
I have configured this interface to receive DHCP from the ADSL Router and for some reason, Clients are not getting addresses.
When I assign a Static address to my laptop I get internet access and all is nice. I tried configuring The WLC internal DHCP server (instead of the ADSL router) and that didn't help. It seems like a DHCP problem but I dont understand the source of the problem of think of the solution.
When turning off the proxy settings I noticed that it helped. Is there anything to do with that? The problem was that after a while the other WLANs starting causing DHCP issues as well.
What is supposed to be configured? Any Expert is the House?
I attached a crappy drawing..

Hi Scott,
Thanks for your answer.
So what you are basicly saying is that I have 2 choices: 1 - disable the Proxy option on the WLC and work with external DHCP servers (internal will not work when this is enabled). 2 - Enable the Proxy option and only work with the WLC internal DHCP.
I have installed many WLCs this way, having Different DHCP Servers (external and internal) for multiple WLANs.
What do you think may be different this time? The router that I am using isn't the most expencive but it is providing DHCP to other clients (wired client) with no problems.
Thanks!!!

VLAN Configuration for Internal and Guest Wireless

Hello,
We are using the following hardware…
SG300-52MP switch -- latest firmware
ASA 5512-X firewall -- 9.1
Aironet AP1131AG WAP
We have the following networks…
10.252.4.0/24 = Internal = ASA-01 interface = VLAN1
10.252.6.0/24 = Guest = ASA-02 interface = VLAN6
10.252.6.0/24 = VOIP = ASA-03 interface = VLAN3
The Aironet supports two SSIDs, Secure (RADIUS) and Guest (WPA2), which are supposed to provide access to the appropriate interface on the ASA.
Relevant parts of the WAP configuration are…
dot11 ssid GUEST
vlan 6
dot11 ssid SECURE
vlan 1
interface Dot11Radio0
no ip address
ssid GUEST
ssid SECURE
interface Dot11Radio0.1

We can manage the WAP through it’s Internal IP address (10.252.4.4).
And the “Guest” wireless network is working -- connecting to that SSID provides the client with the correct IP addressing (10.242.6.X from VLAN6/ASA-02). [Note: the VOIP DHCP and network access also works correctly.]
The “Secure” wireless network is not working however -- the client never receives an Internal DHCP address from ASA-01, and even if you hard-code the client’s IP, no IP4 traffic ever passes.
[Note: connecting a device to a SG300 port with the “Default” configuration provides the client with an Internal DHCP configuration, and it works as intended.]
While this may be a problem with the WAP configuration, I would like to confirm that it is not an issue with the switch not passing traffic correctly.
I have a feeling that I have configured the VLANs on the ports incorrectly.
Relevant parts of the SG300 configuration are...
v1.3.0.62 / R750_NIK_1_3_647_260

Can someone who understands this switch better than I do please confirm the VLAN configuration? THANK YOU!

Welcome to the discussion area!
+PCI regulations do not consider VLAN a secure way of keeping the data isolated. Does anyone have any technical information on how the device creates the guest wireless network ?+
I spoke to Apple Support some time ago and was told that Apple uses VLAN to create the Guest network, and also that formal documentation was not available on this topic. I was referred to the AirPort Extreme Specifications for available information.
This was some time ago, so if you need more up to date info, you might want to try to contact Apple to see if they are willing to share more information about this feature. Although, since VLAN is used, your question may already be answered.
FWIW, to use the Guest Network feature in a home situation, the AirPort Extreme must be set up as the main router controlling DHCP and NAT on the network. If you were thinking of installing the AirPort Extreme behind another router, the Guest Network feature would not be available in this type of configuration.

1941w - Need help with IP address assigning, and relay wireless to a DHCP server.

Hope someone can point me in the right direction -
Basically have a Win08 R2 DHCP server, and a 1941w router.
I've got the internet, got the lan clients getting DHCP ok (with ip helper-address set on the 0/0 internal interface).
Also have the SSID, and wireless clients can connect - but no IPs are being handed out, also not sure if I understand or did the bridging correctly or assigned IPs to the vlan or bvi1 correctly.
for ex:
DHCP server IP:
10.10.2.4
Router Ethernet internal interface 0/0 IP:
10.10.2.1
with helper-address 10.10.2.4 (lan clients are resolving IPs correctly from the DHCP server)
Vlan1 IP address:
10.10.3.1
Does this interface need the helper-address as well? (10.10.2.4)?
wlan-ap 0 IP address:
unnumbered
interface BVI1 IP address (static):
10.10.2.2
am i totally off? not even sure if i have the vlan bridged to the 0/0 adapter or not correctly - but as I said, i can get a wireless client to connect with the SSID.
would appreciate any advice/pointers, thanks

of course - here is the router config:

Help. I have a Google Hangout in 40mins and my sound seems to have vanished. I went to Sys Prefs and it came up with Digital Out....and the Internal Speakers option is no longer there. How do I reboot, or fix this please?

There are many possible causes for this issue. Take each of the following steps that you haven't already tried. Some may not apply to your model. Back up all data before making any changes.
1. Start with the steps recommended in this support article. Don't skip any of the steps. It's the starting point for further efforts to solve the problem.
2. Make sure you have a fully up-to-date installation of OS X.
3. If you've installed an application called "Memory Clean" or any other third-party software that is supposed to "clean" or "purge" memory automatically, remove it according to the developer's instructions and restart. You should do that even if the software is not causing the problem, because it's useless.
4. Other third-party software that has been reported to interfere with sound output includes "Boom" and "Samsung Kies." If applicable, uninstall according to the developer's instructions (not by dragging something to the Trash.)
5. If an AirPlay device is selected for sound output from iTunes (or from other applications via third-party software such as "Airfoil"), deselect it.
6. Launch the application "Audio MIDI Setup" by entering the first few letters of its name in a Spotlight search and selecting it in the results (it should be at the top.) Select Built-in Output from the list on the left. If the Mute boxes are checked, uncheck them.
7. If a red light is visible in the audio-out port when sound should be playing, the internal switch is stuck in the position for digital output. You may be able to free it by inserting and removing a mini-stereo jack of the proper size. If not, the machine needs to be serviced. Inserting any kind of tool in the port may cause damage that won't be covered by the warranty.
If there's no red light, the switch may still be stuck in the headphone position. Try to free it the same way.
8. Disconnect all wired peripherals except keyboard and mouse, if applicable. If more than one display is connected, disconnect all extra ones. Restart and test.
9. If you have a MacBook Air, turn off Bluetooth and restart.
10. Start up in safe mode. Don't log in; just restart as usual when the login screen appears. When you do, make sure the words "Safe Boot" do not appear in the login screen. If they do, the system is still in safe mode and sound won't work.
11. Reset the NVRAM.
12. Reset the SMC.
13. Triple-click anywhere in the line below on this page to select it:
/Library/Preferences/Audio
Right-click or control-click the highlighted line and select
Services ▹ Reveal in Finder (or just Reveal)
from the contextual menu.* A folder should open with an item selected. Move the selected item to the Trash. You may be prompted for your administrator login password. Restart the computer and empty the Trash. Recreate your settings in the Sound preference pane.
*If you don't see the contextual menu item, copy the selected text to the Clipboard by pressing the key combination command-C. In the Finder, select
Go ▹ Go to Folder...
from the menu bar and paste into the box that opens by pressing command-V. You won't see what you pasted because a line break is included. Press return.
14. Reinstall OS X after backing up all data.
15. Make a "Genius" appointment at an Apple Store.
