• ISE Voice Vlan a dynamic assignment using MAB

  Hi all

  I just configured the ISE and the switch for voice authentication for my phones vlan and users. The issue I'm having is attribution a vlan dynamic voice for my VTC units

  Authentication and authorization works well with ISE and I am able to assign the vlan users, but I have problems with the vlan voice.

  Any help would be appreciated!

  Thank you!

  Alex,

  We cannot install several VLANs can one voice. -What are you trying to achieve?

  Do not push no matter what id vlan in the authorization rule. By pushing the class = attribute voice will assign vlan 210 (vlan voice).

  Only the vlan data should be assigned dynamically.

  Hope that helps

  Kind regards

• Public static assignment MAC broken?

  As far as I know, I'm doing everything correctly, but I can't not statically assign a MAC address for a virtual machine in ESXi 4.0 + vCenter 4.0.0 (no patches on either)

  I am trying to assign a MAC address for a virtual machine as 00:50:56:98:37:24.

  I have the virtual machine is turned off, I change the NIC settings in the GUI, and I specify the MAC address listed in the box.

  I get an error saying "the MAC address you entered is not in the valid range. ' Valid values are between 00:50:56:00:00:00 and 00:50:56:3f: ff: ff.

  Now I'm not a math wiz, but I know that the MAC I'm giving him is between. So, what gives? I tried to do the same thing in PowerShell and he complained.

  I resorted to directly modify the VMX file and adding:

  ethernet0. AddressType = 'static '.

  ethernet0. Address = "00:50:56:98:37:24".

  That works fine, start machine, no errors, and the GUI shows the correct value. So is this a bug in the API? I tried via vCenter and directly connected to the ESX Server, both in vain.

  UH... you can double-check your math.  98 is certainly superior to 3F.

• Assign different VLAN wireless authentication

  Dear Stephen,

  I want this product fits the following situation?

  The user will use their laptop to assign the internet by the following situtaion.

  1. they will go to a web portal to choose their internet service provider and connecting to services.

  2. once they got successful connection, they can use their PC to access the internet.

  What I think is that they will have access to a vlan public web portal, once they got the authentication. Their links will assign to differnet vlan (different service provider). Eventually they get the IP address of the DHCP server on MS and go to the internet.

  I can't find a solution for above situation, can you help me?

  I suggest that you go for the Cisco unified wireless solution. More information about the Cisco solution unified are available at http://www.cisco.com/en/US/netsol/ns340/ns394/ns348/ns337/networking_solutions_package.html

  For your scenario, I suggest that you create two VLANS. One for guest users and the other for internal users. An example configuration that is available at http://www.cisco.com/en/US/tech/tk722/tk809/technologies_configuration_example09186a008070ba8f.shtml

• Assign IP address to the Interface VLAN of Web Admin?

  It is a simple question, I can't find can in the web config page to assign an IP to an interface vlan.

  Example: I create a vlan 40 and assign ip 192.168.40.254/24 to it, I can accomplish this with the CLI with 'config; interface vlan 40; "192.168.40.254 IP address 255.255.255.0" but it does not seem to exist in the web interface!

• Defining the second NIC (second IP WAN) same default VLAN

  The VM network simple.

  We currently have all the VMS on the VLAN by default. I'll move the Exchange Server to a physical port separated with a different WAN IP address but I want him to stay on the VLAN by default with all other virtual machines.

  Having a few difficulties of implementation. Can someone point me in the right direction?

  I understand now - it really isn't something that requires a change to your vSphere environment - since both cables should be soon in your firewall, you need to make sure that your firewall is configured so that the public IP assigned to the mail server is sent to the internal IP address on your Exchange Server.

• SFE2000 and VLAN

  Before we begin, I want to say that I saw "' responses to my question, but never exactly what I'm looking for, so I create a new post.  I'm not a network engineer, so please forgive my ignorance.

  We are a public library.  We have a network that includes a number of branches, through the central site of the main library.  We show an ASA firewall. We have a Cisco3825 for local and a series of Cisco2800 Internet connection.  We use a system of 192.168.xx.xx, using DHCP network.  We have a number of PCs that are on the network access to the public and they are locked by using various software that prevent people to do much except get Internet.

  What we want to do is to put the public pc in their own network, always using our Internet connection, but not allowing them to see or access one of our 192. addresses.

  We bought a Linksys SFE2000 and it is my understanding that if I use it as a layer 3 switch, we can do what I suggested above.  However, I get so far and I reached my level of incompetence!  We want that all the public pc to come through the SFE2000 and although about allowing the public to use a wireless connection (but that is located).

  Can anyone offer suggestions or point me to a site that will help me?  Thanks in advance and again, sorry for my ignorance.  I look forward to hearing from anyone.

  Well, the router must have at least one interface. If the interface is used otherwise you can simply run it through the router as well.

  If you want to use the features of the ESF L3 basically configure you the VLAN as I've mentioned before. You enable L3 on the ESF, then you configure filtering on the ESF for the VLAN 'public '. Drop everything that goes in your charge of private VLAN.

  The problem is the connection to the router. We must define a new IP subnet for routing between the CPE and the Cisco. So, basically you will need a 3rd VLAN to connect with the Cisco. You can use a very small for this IP subnet if you wish. For example, add VLAN3 with IP address 192.168.99.101/255.255.255.252. The port on the Cisco configure IP address 192.168.99.102/255.255.255.252. On the ESF, set the default gateway 192.168.99.102. Who should route all internet traffic to the Cisco.

• VLAN and trucking

  I have a Linksys SLM2008 switch and I am trying to accomplish the following. I want trunk port 1 and do be VLAN 1 but handle traffic for all networks VIRTUAL, ports 2 to 5 shall be allocated to the VLAN104 and only handle traffic VLAN104, 6 to 8 ports must be attributed to the VLAN603 and only to manage traffic for VLAN603. This can be accomplished? I tried and I can't operate that way. I have to shared resources at the port of the Cisco switch that it connects on port 1.

  Thank you

  Mike

  Re 5. PVID on port 1 is VLAN1. Is 104 VLAN PVID on ports 2-5. For 6-8 ports PVID is VLAN 603.

  Each port 2-8 must be a member of only one VLAN, unidentified, with PVID to this VLAN. With this setting, all traffic on this port is untagged (which is usually the only type of frame that customer accepts normal ethernet NIC because they don't support 802. 1 q) and all traffic belongs to only one VLAN. It would be the same as the definition of a switch port on the Cisco for access mode and makes member of this VLAN.

  Assigning these marked ports will not work. You can only connect the ports marked with computers or network devices supporting 802. 1 q. Unidentified are normal ethernet frames that work with any ethernet NIC

  What L3 switch or a VLAN router do you use? Without L3 switch or router LAN VIRTUAL, you need to perform completely separate VLANs, which means that they cannot even share an internet connection.

• Change the order of VLAN native?

  Can someone refresh me please as to what the command is to change the VLAN native for the whole switch? (IE: not only on the trunk, I mean the default native for the whole switch). Thank you

  Can someone please refresh me as to what the command is to change the Native VLAN for the entire switch? (IE: not just on the trunk, I mean the default native for the entire switch). Thanks

  Hi Steve,.

  By default, there is only one VLAN for all ports. This VLAN is called by default. You can't rename or delete VLAN 1.

  If you're talking about a management VLAN is nothing else than a VIRTUAL local network that is used for managing in-band of the network switching devices.  To configure this on a switch, you must create a Switch Virtual Interface (SVI) that is mapped to this VLAN, and then assign this virtual interface an IP address.  On a Cisco switch, it would look like the following.

  Interface Vlan99
  IP 192.168.1.1 255.255.255.0
  No tap

  I also want to make something very clear.  Your management VLAN is not to be identical to your VLAN native.  Question, please make sure that they are different.  Your management VLAN must only carry the traffic of in-band management and should not be the default VLAN.  By in-band management traffic, I am referring to SSH or telnet (Although telnet is not recommended because it is not safe).  Traffic such as BPDUS, PagP, CDP, use the VLAN native who is the vlan 1. But if you change the vlan native then CDP, VTP/PagP will always use the vlan 1 but packages will be marked. Only DTP uses vlan native so if you have changed the vlan native then DTP would use the new VLAN to send images. With PVST + BPDUS of course run on all the VLANS.

  Hope to help!

• Help VLAN SG300

  I have install successfully one VLAN but...

  neetwork.jpg

  

  Since 192.168.1.x I can ping everything on 192.168.50.x

  Inside the ports VLAN 50 5 & 6 both the portable and the nas server can talk to 192.168.50.1.

  Since 192.168.1.x, I can access all the 192.168.50.1 resources.

  Inside of VLAN 50 I can ping 192.168.50.1 but can't access anything that anybody else in the VLAN or off.

  From the 192.168.50.100 laptop, I cannot ping 192.168.50.50 (NAS), but I can ping the 192.168.50.1 gateway. I can't ping any internet addresses.

  New kind of learning VLAN here. Any ideas why this happens?

  Hello and thanks for the reply.

  I'm sorry, I didn't know what was the purpose of the configuration.

  If what you're trying to do is to configure your network if the switch then makes the routing steps:

  1 - Position the layer 3 switch

  2. create the VLAN

  3 assign Ip addresses to all the VLANS.

  4 - for all VLANS can get out to the internet, you must create a default route on the switch. It should look like this: 0.0.0.0 0.0.0.0 IP_address_of_router

  5. on the router, you need to create static routes for all the VLANS the router does not know. When you create the static routes, be sure to send this traffic to the IP address of the switch on the same VLAN as the router.

  6 - buy last, perhaps the most important of them step is to ensure that all PC use the IP address of the switch as the gateway by default for the VLAN to which they belong.

  Try this and let us know if it worked. Also, feel free to ask ay if something was not clear enough.

• Uplink port VLAN

  Hello:

  I'm lost

  I know not if you have for example two uplink ports that belong to the same vlan, and two or more NICs for asociated to this VLAN, pinning happen dynamically

  I don't know how to set up a VLAN and assign it to a vNIC

  But I can't found how to link the uplink port to the VLAN in the UCS Manager

  Can someone help me please

  Thanks in advance

  Al

  Al,

  In the end-host mode for ethernet, when you set vlan in the UCSM the vlan is automatically assigning / configured on all uplink and port of the server.

  This is a chapter of the Guide to config:

  http://www.Cisco.com/en/us/docs/unified_computing/UCS/SW/GUI/config/Guide/2.0/UCSM_GUI_Configuration_Guide_2_0_chapter15.html

  However, since version 2.0, there is a feature in which you can control or confiure different VLAN on different uplink ports. This feature is characteristic L2-disjoint and here is a URL to configure:

  http://www.Cisco.com/en/us/docs/unified_computing/UCS/SW/GUI/config/Guide/2.0/UCSM_GUI_Configuration_Guide_2_0_chapter21.html

  I hope this helps!

• SG300 10 p - disconnects after trying to apply the ip to the VLAN

  Its really my first foray into a Cisco SMB device - have tried to configure the SG300 10 p for a few days, but nothing helped. I also upgraded to the latest firmware 1.3.5.58 and now downgraded to 1.3.0.62 and the problem is.

  I am trying to create a vlan and assign an IP address (I am using the L3) - However, whenever I apply intellectual property - I lose connection and then I have to unplug the device again to connect to the rear. For example, if I try to implement the low - courtesy of Tom Watts to the point where I'm creating vlan 200 and assigning the Ip address once I press on enter – it will lose connection. The same phenomenon occurs in the graphical interface. Any ideas where I'm wrong.

  Hi paylo,.

  Are you sure you want to do this on the switch instead of the router? Will you use static IP addresses for VLANs, or do you want your router to deliver DHCP?

  To continue using the switch for routing inter - vlan, make sure the SG300 is mode layer 3.

  1. If you are currently in mode layer 2, open a CLI connection and issue command:

  router adjustment system mode

  Take note that this will delete your current config and the switch will reboot.

  2. create the VLANS on your switch under management VLAN-> create a vlan

  3. go to IP Configuration-> interface ipv4 and assign each vlan a static IP address for the switch in the subnet for the new LAN virtual

  4. vlan management-> the Interface settings. I leave all ports as trunk ports, or change the Trunk ports, if you have already changed their.

  5. vlan Management-> Port VLAN membership. Assign your VLAN ports appropriate.

  6. when everything is all connected, you should be able to see the switch of the static routes for you already created under static Configuration of the IP-> IPV4 routes. Make sure all your subnets are there and demonstrate local range type

  7. you may need to add a route for example 0.0.0.0 with the next hop is your router

  At this point, you should be up and running, with all them VLAN connected to each other and to the internet.

  If you want to restrict access between them VLAN, you will need to create access control lists.

  You must first create an ACL (Access control-> ACL based IPV4) and give it a name. then move on IPV4 based ACE where you put real access control rules.

  This is a sample set of rules that I did, it will block all access between two subnets (each vlan that you created above should be its own subnet) and allow certain traffic like 3389 - remote desktop, etc. You will need to customize according to your needs and IP subnet. So for ex, to enable the Xbox access the file server, rather than all - everything, you put the xbox or IPs specific subnet as the source, the file server as destination, and the ports as source ports. Don't forget to do the reverse of the rule as well.

  

  Then go to-> links ACL access control and bind the list control access to ports there.

  Hope that helps, good luck with your game to the top.

  Best,

  David
