ISP Handoff and VLAN configuration...

I am completely new to the cisco configurations, but do have some experience configuring other routers and firewalls.
The problem I am having is configuring my cisco 2911 integrates services router to work with the IP info they provided me:
WAN BLOCK: X.X.254.108/30
WAN SUB: 255.255.255.252
LAN BLOCK: X.X.255.72/29
LAN SUB: 255.255.255.248
USABLE IP's: X.X.255.73-78
CUSTOMER SERIAL: X.X.254.110
ISP SERIAL: X.X.254.109
In the setup I am working with, the Cisco 2911 will then connect to our firewall so it will be: ISP ethernet > CISCO 2911 GE0/1> CISCO 2911 GE0/2 > fiewall...
The ISP said I needed to "strip the VLAN" which I assumed the router should do on its own, however, I am unsure pf the IP address that I need to configure for the GE0/1 and GE0/2 interfaces... and if there is additional configuration necessary because the circut is comming to us over a metro ethernet VLAN (if thats what its called).
THANKS SO MUCH FOR YOUR HELP!
-Dan

Some more info:
Not that this makes a huge difference but our usable IP's are 74-78, not 73-78
also, I was told by my ISP that our VLAN ID is 125 (I dont know if I need this in the configuration, I assume I don't) and that I need to 'strip the VLAN' which I am pretty sure is done by the router itself???
Finally- since I am new to this - I was wondering if I need to configure anything on the router that would incorporate the "VLAN" - I will try simply setting the WAN interface to the xxx.xxx.254.110 and the LAN interface to xxx.xxx.255.74 and see if that works tomorrow and see if that works.
Thanks~

EA6500 - VPN interface and VLan configuration feature?

Does EA6500 has any kind of built-in VPN interface and also built-in VLan configuration feature??

This particular router has VPN passthrough and you may open ports when needed for VPN to work behind it. As for VLAN configuration, this router is not designed for that. Everything that you would like to know about the router just click here

Multiple vlans configuration issue with RV016 router and SG 300-10MP witch

Hi,
I have to configure multiple vlans served with a unique DCHP server . As first step, I just will The DHCP server to serve 2 vlans. The following is the hardware and configuration that I implemented :
Router (RV016 10/100 16-Port VPN Router) as gateway mode:
IP : 172.16.0.1/24
DHCP Server :
IP : 172.16.0.2/24 GW: 172.16.0.1
2 subnets :
172.16.1.0/24 GW: 172.16.1.1 to serve vlan 1
172.16.2.0/24 GW:172.16.2.1 to serve vlan 2
Switch (SG 300-10MP 10-Port Gigabit PoE Managed Switch) as layer 3 mode:
IP 172.16.0.254 (vlan 8 default)
Vlan 1 : 172.16.1.1
Vlan 2 : 172.16.2.1
1 device connected on each vlan
a workstation on the vlan 1
a laptop on the vlan 2
In this scenario (see the attached pdf file) the DHCP server is connected on a router, hosts on vlans dont receive any IP address.
But If I connect the DHCP server on a trunked switch port and adapt the DHCP server gateway 172.16.0.1 to 172.16.0.254, hosts receive ip address properly.
I have to connect the DHCP server directly to the router. How can I do that, what is wrong in the configuration ?
I hope the explanations are clear enough and my English too
Any help will be highly appreciated,
Zoubeir

Hi Eric, the small business group doesn't support the ASA config, but I can help with the switch.
A couple things I notice in your description-
48 port (192.168.1.254) and the other 24P (192.168.1.253) we have a second vlan 20 set up on the 24P switch (192.168.2.253) we have ports 1-12 set for vlan20 (untagged and trunk), the remaining ports on on the default vlan 1.
The connection between the switches, is it 1u, 2t?
The link between the switches should be 1u, 2t, the switches support the trunking and vlan tagging, meaning all communication will work fine.
We have the 24p and 48p switches connect using GE1 and GE1. We are unable to ping a device on vlan 20 ( on the 24p switch
The 24p switch should be in layer 2 mode, if you have the 48 port l3 switch upstream. Additionally, you need to have the default gateway set on the 24p switch.
We have a static route set on the 24p switch (0.0.0.0 192.168.1.0).
Between the switches, it shouldn't require any static routes, assuming you correctly trunk / tag your ge1 ports, with both switches operating in l3, the ip route table dynamically builds the connected routes, therefore a static route is redundant.

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

interface BVI1
ip address 10.252.4.4 255.255.255.0
no ip route-cache
ip default-gateway 10.252.4.1
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.

SRW2024P and problem configuring VLANs

Hi all,
I'm trying to configure 2 new VLANs on SRW2024 switch, and I cant get this to work.
I have default VLAN 1, and I created a new VLAN 100 called HOME and VLAN 200 called WIFI. I connected on port G1 a normal router (non 802.1q capable router) and set that port to General. PVID 1.
Then I connected a WinXP computer on port G9 and I set that port to General. PVID 200.
I cant ping from port G9 to internet, why?
Best regards.

internet connection on multiple vlans is only possible when using a router that supports 802.1q

Help with inline VLAN Pair and switch configuration

Hello,
I'm new to IPS and IDS in general, but I have an IPS-4255 and a couple of Catalyst 2900 switches to experiment with. I'm currently trying to enable an Inline VLAN Pair configuration on the IPS and have a simple setup.
SW1 and SW2 have vlans 100 and 200 configured. PC1 and PC2 are on the same IP range (no routing). PC1 on vlan 100 connects to Sw1. PC2 on vlan 200 connects to SW2. The IPS connects to a SW2 trunking port, and SW1 and SW2 are connected together on another trunking port.
I know that my trunking is working because PC1 and PC2 can ping each other whenever they are on the same vlan of either switch. But, they can't ping when on the separate vlans.
From what I've read, the IPS with an Inline VLAN Pair acts as a bridge between the two vlans and should forward the traffic if it passes inspection. However, the IPS does not appear to see any traffic at all.
My IPS is configured with inline VLAN pair 100->200 and associated to vs0.
Have I missed something in my config somewhere? Or am I misunderstanding how inline VLAN Pairs are supposed to work?
Below are my configs for the switches and the IPS.
Any help would be appreciated. Thank you!

It has been awhile since I've dealt with a 2900 switch to I am just trying to guess at what may be wrong with your setup.
I noticed that neither of your trunk port configuration are specifically stating which vlans are allowed on the trunks.
It is possible that for the trunk between the 2 switches there may be some protocol negotiation so the switches can determine which vlans to trunk, BUT no such negotiation will happen with the sensor. If I remember right you will need to specifically state which vlans the trunk to the sensor should carry. If I remember right the commmand would be something like:
switchport trunk allowed-vlan 100,200
You will want to find the show command on your switch that will show you which vlans are actually being trunked by the port. It might be something like "show switchport trunk"
And you will want to verify that the switch is actually trunking vlans 100 and 200 to your sensor.
On your sensor you will want to execute "show interfaces" and look at the statistics for Gig0/0 to see if it is receiving packets on vlan 100 and 200.
You can also run "packet display GigabitEthernet0/0" to see if any packets are making it to your sensor.
You will also want to check Link status and make sure your sensor is linking up properly with your switch. A common mistake is to connect the wrong ports, as some sensors do not have the port numbers clearly marked.
NOTE: If the above doesn't help, then take the additional step of eliminating the second switch. Attach both pcs to the same SW2 switch (1 in each vlan). The second switch isn't necessary to test the inline vlan pair functionality. Connecting both PCs to the same switch will help eliminate any possibility of misconfiguration between the 2 switches.

Application Administrators can't see VLAN configuration on VMs in VMM 2012 R2

Hi, I have the following issue on my VMM 2012 R2 infrastructure.
I have created a cloud with a Hyper-V Cluster in it. Configured a Application Administrator Role (Self Service) and assigned all permissions related to this cloud and Hyper-V Cluster, including a couple of VM Templates and a VM Network.
They users can see the VMs, create VMs but they cannot configure the VLAN inside the VM.
If I go to the VM settings using the full VMM admin, I can do it, select the VM Network and then select the appropiate VLAN, but when I try to do this using the Application Administrator account I configured specifically to this Cloud and Cluster, I can
select the same VM Network but can't see any options related to VLAN configuration.
What am I missing? Is this the default behavior? Do I need an additional permission? Where?
Thank you for your responses.
Regards.
Eduardo Rojas

That is correct.
Application Admins 'consume' resources (compute and storage) and have no insight into the physical part. Especially if you are using the cloud abstraction. "Administrators" manage the physical layer of things - that is why you can see
/ set the VLAN ID directly.
I believe that you would need to create your Virtual Networks with the proper VLANs and the application admins can then choose based on the Virtual Network.
The worst case is that you define a Virtual Network per VLAN so that your application admins can select an item that correlates to a specific VLAN configuration.

SGE2010 and IPv6 configuration

Dear sirs,
I own a /48 ipv6 address block , and i'd like to cut it in /64 blocks with a SGE2010 switch .
Layer 3 and IPv4 configuration works well : IP configuration on vlans and IP routing between vlans.
MachineA (172.18.10.200) <====> (172.18.10.253/24) switch (172.18.255.1/24) <=====> MachineB (172.18.255.100)
I'd like to do the same configuration in ipv6 : but i experience problems :
When i want to add an ipv6 interface, it doesn't add it, but replaces the already defined ipv6 interface.
I first thought of a problem with web administration interface , so i tried to define a configuration file like this :
vlan database
vlan 2,255
default-vlan vlan 10
exit
interface ethernet 1/g6
switchport access vlan 2
exit
interface ethernet 1/g47
switchport access vlan 255
exit
interface vlan 2

ip address 172.18.1.253 255.255.255.0

ipv6 nd dad attempts 0
ipv6 address 2001:7a8:5a90:1::60/64
exit
interface vlan 255
name Admin
ip address 172.18.255.1 255.255.255.0
ipv6 enable
ipv6 nd dad attempts 0
ipv6 address 2001:7a8:5a90:255::1/64
exit
interface vlan 10
ip address 172.18.10.253 255.255.254.0
ipv6 enable
ipv6 nd dad attempts 0
ipv6 address 2001:7a8:5a90:1000::2/64
exit
hostname sw-48-1g
clock timezone 2
And i uploaded it through the web interface , replacing the startup-config.
After rebooting the device : only the vlan2 ipv6 configuration is used ... all other vlans only respond in IPv4 .
Did I made something wrong ?

WLC2112 with Guest / Web-Auth and vlan

Hi
I'm trying to configure my WLC with guest SSID and vlan 10.
The security is only set to Web-auth, and it is all working if the guest network is set to nativ vlan (1) But it seems that the http(s)://1.1.1.1/login.html is not reacheble from the guest SSID/VLAN??
Please help.
Management IP Address 192.168.14.252
Software Version 6.0.182.0
Emergency Image Version
I have tried with ver. 5.2 also -

I think that 1.1.1.1 is only reachable from a wireless client during webauth. They should not be able to reach that address once they have passed through the web auth page.
Don't know if that helps, or not.

Fwsm - active/standby - "Vlan configuration mismatch between peers"

Hi,
A FWSM pair fall in to active active sittuation due to a vlan configuration mismatch. What would be the best way to synchronize configurations and return to the normal active/standbay? There is a new vlan on the primary fwsm and at present both are in active state.
Thank you in advance.
Zdravko

Hi,
To my understanding the FWSMs (even though both active) have identical configurations?
Have you perhaps done so that on the core switch you have only issued the "firewall vlan-group only on the primary core device (to which the FWSM is attached) and not the secondary core device?
The only time I have witnessed the same situation is when configuring a new customer link and I have only configured the primary unit (and about to configure the same on the standby unit)
Hope it helps, not sure if the above was what you meant.

Help with wireless controller and VLANs

Hi I'm trying to setup a wireless controller in preparation for a large site go live later this year. I'm struggling to get the controller and the WLAN using the correct VLAN. I want the controller on VLAN 100 and the clients on the WLAN on VLAN 200.
My thought is that I would need a config similar to:
Switchport for wireless controller management port set to trunk VLAN 100 and 200 with no native VLAN set.
The management interface on the controller set to VLAN 100.
A dynamic interface created on VLAN 200.
When setup like this I can get to the controller on its management address but only from VLAN100 not from another VLAN on site or from other sites over the WAN.
I have setup a WLAN which is set to use the dynamic interface on VLAN 200.
I have set the AP to use HREAP and set the native VLAN as 200 and added the dynamic interface into the VLAN mappings
When I connecting a client to the WLAN I get an address on VLAN 100.
The switchport for the AP is set to native VLAN 100 and trunk 200 – this setup works for standalone APs at other sites.
What am I missing?
Also any idea why the management interface address is not routing? The netmask and gateway are set correctly.
Thanks
Paul

Just to add to Steve's post... You only need to create a dynamic interface for vlan 200 if you have ap's also in local mode. If your ap's are in H-REAP/FlexConnect mode, you don't need a dynamic interface for vlan 200.
In you H-REAP/FlexConnect ap, you would set the wlan to vlan mapping there and the switchport configuration would be a trunk allowing vlan 100 (im assuming your native vlan for your ap) and vlan 200. You should see something like the following:

Multiple SSID With Multiple VLANs configuration on Cisco Aironet APs: Assotiated clients cannot obtain IP addresses

Hi Surendra,
I was just given this task to see how i can configure a second ssid for guest access in our environment.
this is our network setup prior to this request: Internet----Firewall (not ASA)---ce520---C1131AG and CME router is also connecting to the ce520 switch. we only have two vlans: one for voice and two for data.
Presently, there is no vlan configured on the AP because it on broadcasting ont ssid and wireless users gets IP from a windows DHCP server on the LAN. the configuration on the ce520 switch port for the AP and other switches say access vlan is the DATA vlan which automatically becomes the native vlan for all trunk port connecting the AP and other Stiches to the network.
Now with this new requirement, i have made my research and i have configured the AP to broadcast both the production and the guest Vlans. The two vlans are 20-DATA and 60-Guest. I made the DATA vlan on the AP the native vlan since the poe switch is using the DATA vlan as native on the trunk ports. I configured the firewall to serve as DHCP server for the guest ssid and i have added the ip helper-address on the guest vlan interface on all switches while the windows server remains the dhcp server for the production DATA Vlan. I have confirmed that the AP, switches can ping the default gateway of the guest dhcp server which is another interface on the firewall. I can now see and connect to all broadcasted ssids but the problem is I am not getting IP addresses from both the production dhcp server and guest dhcp server when i connected to the ssid one at a time.
My AP config is attached below.
Please tell me what am I doing wrong.
Do i need to redesign the whole network to have a native vlan other nthan the data vlan?
Does the access point need to be aware of the voice vlan?
Do the native Vlan on the AP need to be in Bridge-group 1 or can i leave it in bridge-group 20?
I will greatly appreciate your urgent response.
Thanks in advanced.

Hi,
As far as i know we dont set the ip helper address on the radio interface. It should be on the L3 interface of corresposding VLANs i.e.
int vlan 20
ip helper-address 192.168.33.xxx
int vlan 60
ip helper-address 130.20.1.xxx
I'm assuming that your using SVI's (int Vlan 20 and int Vlan 60) rahter than physical interfaces. Also hope you have configured switch port as trunk where this AP is connected.
Modify the AP config as below since you are using data vlan as the native vlan
interface Dot11Radio0.20
encapsulation dot1Q 20 native
interface FastEthernet0.20
encapsulation dot1Q 20 native
Ideally your AP fastethernet configuration should looks like below and not sure how you missed this as this comes by default when you have multiple vlans for multiple ssids.
interface FastEthernet0.20
encapsulation dot1Q 20 native
no ip route-cache
bridge-group 20
no bridge-group 20 source-learning
bridge-group 20 spanning-disabled
interface FastEthernet0.60
encapsulation dot1Q 60
no ip route-cache
bridge-group 60
no bridge-group 60 source-learning
bridge-group 60 spanning-disabled
Hope this helps.

Interesting Document: Service Deployment and Service Configuration within the Internet of Things

Hi All,
an interesting document:
Service Deployment and Service Configuration within the Internet of Things
Best regards,
Andy.

Hello Marek,
I suppose you are not planning to do any kinds of advanced config using several VLANs and multiple SSIDs so let's just make your configuration simple and working.
In short, you need to remove all references to VLAN 1 and to any subinterfaces possibly related to the VLAN 1. This means in particular (follow these steps in sequence):
Remove the Dot11Radio0.1 subinterface entirely
In the Dot11Radio0 section, remove the encryption vlan 1 mode ciphers tkip command
In the dot11 ssid ciscowifi section, remove the vlan 1 command
After performing these steps, make sure that the ssid ciscowifi and encryption mode commands are still present in the Dot11Radio0 configuration, and if not, reenter them.
Best regards,
Peter
