Issue between internet and VLANs

• Issue between Cisco and ESX switch

  It is a small deployment with an ESX Server running a Windows Small Business SERVER 2003.

  ESX server has 2 network cards, previously a NIC was connected to a small FastEthernet Switch netgear and all workstations have been working on it.

  I replaced the netgear with a Cisco WS-C2960S-24TS-S and the field still works fine, the problem is that I can't connect to the service console or the VI client from a computer connected to the switch.

  I can't ping the IP switch ESX service console and also can not ping the switch since the service console.

  Switch and ESX console can ping the Windows Virtual Machine and the virtual machine can ping both of them. Therefore, I can get to the VI client via Wirtual Machine (not the best scenario to manage one of its right VMS ESX host?)

  I don't know what the problem is, but it sounds a lot there is a problem with the configuration of port / vlan on the cisco switch.

  Can a Cisco expert help out me here?

  Here are some details of the configuration.

  Port group service Console and the port Vm group do not use no matter what config VLAN on the ESX Server.

  Thank you

  I think I've seen this before. I'm not super familiar with this switch, but I think that the problem is with cisco-computer office macro.

  Try using the macro switch cisco instead since you are addressing a vSwitch on the other end. You can always check the mac address table and see if your Mac to the vswif (service console) make their appearance. If they are not then appear this is an inconsistency in the port between the Cisco Switch and vSwitch.

• NSX - Ping issues between DLR and edge gateway on the network of public transport

  Hello

  I have deployed an NSX in a POC environment and have a few weird questions. I sent a distributed router (DLR) with 2 internal interfaces (related to the segments of NW app & web) and an uplink interface connected to a network of transit (192.168.10.0/29). I have also deployed a gateway of Edge services with an internal link connected to the same interface of transit (192.168.10.0/29) and an interface of uplink connected to the outside world.

  The question is, when I PuTTY on the Edge service gateway and ping interface uplink of the DLR using sound transit (192.168.10.2) network ip address, I do not get a response. The firewall is configured to accept all traffic on the DLR and the edge.

  Someone at - it ideas? Note that the DLR has been configured default gateway pointing to the IP of the gateway of the Edge on the network of public transport (as is the only North DLR connection)

  See you soon

  A rough drawing of the topology is attached. Ping fails to 192.168.10.1 to 192.168.10.2

  FYI - has proved to be a problem with the NSX 6.1.2 that attaches to 6.1.3. No KB for the issue for the time being, nor is he mentioned as being fixed at 6.1.3 in the notes but VMware engineer GSS confirmed that its fixed.

  temporary work is about to stop and start the daemon netcpa on the compute cluster hosts & edge of ESXi

• Difference between groups of ports and VLANS

  Hi guys

  I read ESX Admin guide 2 times till now, but I still don't know what exactly is the difference between groups of ports and VLANS? I understand, but if someone asks me this question I will not be able to respond with confidence.

  Network also label: my understanding is that it's just label No technical significance in configuration?

  Thanks in advance

  One VLAN is one of the many settings that you can configure for a group of ports, you also have the tabs security, Traffic Shaping and consolidation of NETWORK cards.

  Port group name, you associate you a VM port group must be placed systematically on other hosts if you want to migrate or virtual failover from one host to another.

• Firewall between ESX and vCenter vLAN & Production vLAN

  Hello

  Scenario:

  2 ESX hosts with Teddy bear 6. 2 to vLAN S.C. & VMotion, 2 to vLAN DMZ and 2 for the Production of vLAN.

  There are 2 pSwitches to battery-Mode Cluster, having 4 VLANS.

  1. Production of vLAN1

  2. vLAN2 DMZ

  3. Service vLAN3 console

  4. vLAN4 VMotion

  Connectivity is fine no problem. All VLAN works them very well. Service console and VMotion they fold each other so pSwitch failure failure or Teddy bear.

  Requirements:

  Service console is connected in vLAN3 which is 172.16.20.0/24 network under vSwitch0 contains 2pNICs & 3 exchanges.  Service Console PortGroup, VMotion PortGroup & vCenter PortGroup. vCenter PortGroup I want to place the VirtualCenter VM & I'll put the virtual computer's firewall.

  Currently, the Center Virtual under vCenter PortGroup, which is 172.16.20.55. Communication to ESX all very well.

  How I connect to VirtualCenter & ESX host while I am putting in the Production vLAN? I added a static Route in my P.C. 172.16.20.0 to go via 128.104.145.149 "this is the IP address pSwitch" I connect very well without any problems. Of course that does not protect the farm ESX and virtual Center.

  I want to secure the connection between the Production vLAN & Console of service of VMotion vLAN & get rid of the Static Route in the computers in the Admin.

  Bypass the Options:

  1. Physics MS ISA Server with 2 natachasery one be connected in the vCenter PortGroup & to be connected in the Production vLAN & open ports to demand it.

  2. Physical firewall of Teddy 2 a be connected in the vCenter PortGroup & to be connected in the Production vLAN and open ports require.

  3. Virtual Firewall 'SmoothWall or ISA Server' with 2 teddy bears that are connected in the vCenter PortGroup & to be connected in the Production vLAN and open ports require.

  Please take a look at the diagram attached & tips.

  Best regards

  Hussain Al Sayed

  Hello

  On your diagram, I would change your colors. Orange traditionally involves a DMZ not green, but it is up to you. I use Smoothwall for exactly the same behavior.

  Network <-> pNIC1 <-> vSwitch1 <-> vFW (smoothwall) <-> DMZ Network
  ....................................................<-> Green Network
  

  If your front firewall controls access to everything. You can use 'two' firewalls so if you just want to have a set of Red<->Green Networks. On the first, the Red network is outside, green is the demilitarized zone, in the second, red is the demilitarized zone and the ESX hosts are green.

  To grant access to your ESX hosts from a system outside the firewall, you must enable and redirect port 443 to the appropriate location. In fact, I wouldn't do that, create a virtual machine or physical box that is inside the firewall, use the VPN and OpenVPN Tarek Smoothwall addon in the internal location or create a pinhole that allows RDP access to this host/VM and then use the VIC of in the "green network". You must put the kingpins holes in your firewall to grant access you need, so a VPN works much better. You want to limit the number of holes of PIN you use.

  What you describe is quite feasible, but without the holes of the kingpins and proper routing through the firewall is not possible.

• Trouble with the voice and data Vlan vlan translate between CT3905 and SF300 - 24 p

  Hey actually, we have the solution to monitoring of implementation with CT3905 phone, SF300 - switches 24 p cameras and AIR-AP1041N Access Points

  

  We have the problem with the vlan tag in SF300 switch ports - 24 p we can´t tag vlan of the voice and data VLANs on the same port on SF300 - 24 p it is Possible or we must dedicate a port for each VLAN or ussing the same data segment of VLANs and vlan voice?

  Someone has an answer or technical documentation that can help us

  Best regards

  First of all,

  Please disable lldp transmit in SF 300 switch.

  The command is "no lldp transmitted."

  After you disable check the following steps.

  facing the same problem with cisco SG 300 and 3905 ip phone switch.

  And nested thing was my 7945 and 6941 phones use to work properly, without above configuration.

  Cisco 3905 became not vlan Ip address votes and even if I put static, it did not work.

  After a long struggle, I was able to solve the problem. Now both phone and system work fine in the same port.

• WLAN and VLAN

  Hi, I have a network with srw248g4p and srw224g4 WAP200 access points.

  also, the router is linksys, such as provided by the DSL provider

  Is this enough to configure different wireless LANs, so a WLAN can only connect to the internet, and other WLAN will be internal and internet network

  I would like to continue with regular, if possible WPA2 security.

  Do I need a WLC (e.g. WLC2106) to allow this, or can it be done with the current equipment. Are there other conditions that I have to take care of?

  Are there conditions for the router, or is it enough that it serves as a DHCP server?

  Thanks in advance

  'Stand-alone' (or 'stand-alone') means only "does not work with the controller. An autonomous access point is set up autonomous AP itself. There is no other way to do it with the WAP200. Access point unlike Cisco Aironet the WAP200 cannot be converted to a 'unified' in a WLC version controller. If you have a dozen WAP, you must configure each individually, i.e. assign the LAN IP address, set up the SSID, wireless security, VLAN, etc.. If you need to update firmware, you must update each individually. That's what I hear with "autonomous".

  You can use WAP to provide several separate wireless networks that connect to separate VLANs, for example a guest VLAN and your VLAN normal. Separation is achieved by the 802 tag. 1 q VLAN. You can WAP to connect to one of your SRWs if the connection port is configured correctly. You can also directly connect the WAP200 to any router that is able to manage the 802. 1 q VLAN.

  The problem of routing VLAN remains the same: If you have multiple VLANs and deliver them through a single router in the internet and perhaps some of the traffic between them VLAN you will need a router that is able to manage the 802. 1 q VLAN.

• 2 SSID and VLAN on each access point

  I'm new to Setup IOS APs and wireless, in particular, a couple of 1142Ns in autonomous mode and are looking for answers and examples. These APs will be connected to the POE on an ASA 5505 firewall ports. I also set up the 5505.

  The requirements are that each AP have a SSID 'internal' and 'external' and each AP will have two VLANS.

  The APs should allow roaming between them.

  Internal SSID will allow full access to the company's internal network and the Internet and will use WPA2. It will use the corporate dhcp server and the dhcp server to use IOS to distribute addresses.

  The external SSID will not have access to the Internet and use WEP. The ASA 5505 provide dhcp on these clients.

  The two ports PoE on the ASA 5505 will be shared resources for inside and dmz VLAN.

  If anyone has examples of any of these conditions, observations or similar config they are willing to share, please post them.

  In particular, I would like to see an example of homelessness config Setup VLAN, SSID config and Setup WPA2 and WEP.

  Thanks in advance.

• High CPU consumption (always between 12 and 30%)

  I am running Firefox 9.0.1 for Mac. Until the upgrade to version 9.0.1 I had no use of high CPU problems...

• HP Pavilion 15 t issues with Internet connectivity can be used under Windows 8

  So I just got my new HP Pavilion 15 t-e000 CTO Notebook PC last week, it runs Windows 8 & amp; It is a 64-bit.
  
  The only problem I've had is to stay connected to my wireless Internet. The connection stops at random intervals saying 'Limited' instead of 'connected '. I have to constantly disconnect and connect to my WiFi. It's particularly frustrating when I am trying to download something that lasts longer than a few minutes because the Internet connection cuts, and I have to start the process.
  
  I tried pretty much every "difficulty" people have posted that worked for some people. No luck for me. Sometimes it seems that he will stay connected and then I try to connect to a web page or download something and it turns off again.
  
  -Turn off the "Allow computer to turn off this device to save power" under power management in the properties of my wireless connection section... DID NOT WORK
  
  -By using the command prompt to reset the network card... DID NOT WORK
  
  -Running the network and Internet, and convenience stores something... Didn't WORK * update: if I run the connection test network via the HP help/support on my desk Center, while the connection says Limited, I get the notice that the 'default gateway was not available"and the router has been handed over to zero and issue fixed, etc. BUT if I run the test, while the connected said wireless, the test still says there is no problem. And although the test 'fixed' the issue, it does not because the Internet always cut again.
  
  -Updates Windows has installed new updates several times... DID NOT WORK
  
  -Forget the wireless network and set up as a new... DID NOT WORK
  
  -With the help of my computer right next to my wireless router... DID NOT WORK
  
  Used wireless router is: Cisco Linksys Wireless-G 2.4 GHz router to wide band as well as our network is WPA with a security code. We also have an Internet DSL SpeedStream thing (sorry, I don't know what it's called). The Compatibility Center said that this router is compatible with Windows 8. Other computers running Windows 7 and Windows Vista, iPhones, iPads and all work fine.
  
  My laptop uses Intel Centrino Wireless - N 2230 and the light is on and it still says ' device working properly "in the properties.
  
  For any help or suggestion would be greatly appreciated because I am at my wits end.
  
  Thank you

  Therefore, it seems that my problem with the limited Internet connection has been resolved. I didn't use my computer for two days and this afternoon, when I turned it on I was still having problems. However, I went to the HP Support Assistant, and it appeared that I had a few updates to download and install, so I let him do his thing. It took awhile because the Internet kept cutting out, but once the update for the wireless Intel have finally set, my connection is REMAINING CONNECTED. Finally!

  I don't know why when I went into the properties wireless it says "device working properly ' and when I tried to update the driver it says"your driver is the latest version"or something else.

  I suggest you just go to the HP Support Assistant and updates in the section "Updates and the updates of". It was a bit random, but touch wood my looks of problem connecting wireless to be gone.

  Hope this helps
