How to create VLAN on Cisco PIX 6.3?

Hi,
how to create vlan on pix-6.3? i am bit confused.
how do i assign a single internet face with multiple ip address(not secondary IP address) for each & every vlan?
how to i connect to the switch, i mean if i put "switch port mode trunk" on the switch side, what command should i need on the PIX "inside" interface? in router the command is "encapsulation dot1Q 1"
also is there any restrictions that only limited vlans can be created or it is unlimited?

hi
When you configure your interface, you usualy do it like that
interface ethernet0 auto
interface ethernet1 auto
Let's say that ethernet1 is a trunk with 2 vlan and a native vlan, you need to add to your config:
interface ethernet1 vlan100 logical
interface ethernet1 vlan200 logical
After that you need to name those interfaces and set the security level.
nameif ethernet0 outside security0
nameif ethernet1 inside security100
nameif vlan200 V200 security4
nameif vlan100 V100 security6
This configuration will give you an interface(eth1) with 1 native vlan(inside) and 2 tagged vlan(v200 and v100)
PIX will not negociate a trunk, your switch config is correct.

Creating VLAN on Cisco 3800 Series

Hello
I am new to networking. We have a Cisco 3800 series router with 64 ports. We have connected servers and PC's directly to the back of the router. Almost all of the ports are used with the exception of few. We would like to create a VLAN for the remaining few ports. I am able to telnet to the router or connect directly using hyper terminal.
I have been told that we cannot create VLAN's directly on the router. For that purpose we need to first get a switch and connect the switch to the router, then create VLAN’s using the switch. Can someone please provide some tips? Any suggestions would be nice…Thanks

How to create VLAN in standalone Hyper-V

Hi,
I have installed Windows 2012 R2 on HP DL Server and done the teaming as per below on physical box
NIC1 + NIC2 = Team 1
NIC3+ NIC4 = Team 2
Now, we are planning to create two VMs with different subnet then base OS –
Base OS Subnet = 192.168.10.1/24
VM1 Subnet = 192.168.20.1/24
VM2 Subnet=192.168.30.1/24
Please let me know how to achieve this by hyper-v networking.

Hi Suhag,
>>Yes, I am trying to dedicate the physical interface for VMs (if possible) to avoide trunk/VLAN configuration on physical and virtual switch.
Vlan is virtual LAN , it means computers can not access other computers which is in different VLAN (second layer switch ).
If you just want VMs to use dedicate physical NIC ,it is not needed to use VLAN .

How to create tunnel in cisco router

Please give me command wise configuration about creating tunnel in router as:
tunnel ip address:-
destination ip
source ip:-
any other command

Hello Sunil,
I guess what Jed wants to stress is that prior to IOS 12.2(8)T, a tunnel interface would not go down even if the underlying physical connection would go down. As of IOS 12.2(8)T, you can configure keepalives on the tunnel interface, which cause the interface to go down when the keepalives are missed.
Check this document for details:
Cisco IOS Software Releases 12.2 T
Generic Routing Encapsulation (GRE) Tunnel Keepalive
http://www.cisco.com/en/US/products/sw/iosswrel/ps1839/products_feature_guide09186a0080087cec.html
As for the tunnel configuration itself, in addition to a basic GRE tunnel as mentioned in the post above, there are additional ways to configure a tunnel. In the links below, you find many configuration examples:

VLAN's Cisco SF 300-24

I need create vlans in Cisco SF 300-24 Switch.
Ports 1 to 6 are available for other ports (from 7 to 24).
For examples:
port 7 is available for ports from 1 to 6 but is not available for ports from 8 to 24,
port 8 is available for ports from 1 to 6 but is not available for ports from 9 to 24 and 7,
port 9 is available for ports from 1 to 6 but is not available for ports from 10 to 24 and 7 and 8,
.....(to port 24)
How I can do it?
When I add ports from 1 to 6 to VLAN 12, the ports was automatically removed with VLAN 11(in attachment).

Hi Dominik,
Here are the rules for VLANs ..
When you set the switch port interface to access mode, a switch port can be only a member of one untagged VLAN
When you set the switch port interface to trunk mode, a switch port can be a member of only one untagged VLAN but also a member of many Tagged VLANs.
But what you seem to be trying to achieve is use ports 1-7 as unprotected or open ports for ports 8-24 within the switch.
Really seems like something called Priveate Vlan Edge PVE, whereby protected ports will only forward packets to unprotected ports and not other protected ports. .
Here is the definition found in the help text from within the switch.
Protected Port—Select to make this a protected port. (A protected port is also referred as a Private VLAN Edge (PVE).) The features of a protected port are as follows:
Protected Ports provide Layer 2 isolation between interfaces (Ethernet ports and Link Aggregation Groups (LAGs)) that share the same Broadcast domain (VLAN).
Packets received from protected ports can be forwarded only to unprotected egress ports. Protected port filtering rules are also applied to packets that are forwarded by software, such as snooping applications.
Port protection is not subject to VLAN membership. Devices connected to protected ports are not allowed to communicate with each other, even if they are members of the same VLAN.
Both ports and LAGs can be defined as protected or unprotected. Protected LAGs are described in the Configuring Link Aggregation section.
So my steps were
So I am wondering if you really need to configure alot of vlans.
make ports 8-24 protected port
Save the configuration
Clicked to tick the option to protect switch port 8.
That's what we end up with , port 8 is now protected.
Now lets copy the settings from port 8 to ports 9-24, see the circled area below.
now will in the ports you also wish to protect.
Now ports 8-24 are protected ports.
Hosts on these ports will only be able to communicate with hosts on ports 1-7 or switch port 24 onwards, in the case of my switch.
Make sure you save your configuration.
I hope this is what you want.

Wrv210 How to use vlan feature?

Hi people.
I have 1 WRV210 Wireless Router, this device have the vlan feature, I have read about this feature that u could have separate networks example:
192.168.10.X net-1
10.0.8.x net-2
My ISP use pppoe, is working, but I dont know how to setup 2 networks with this device? The manual just tell u how to create vlans but is all nothing more.
Can someone help me with this?
Suppose that I have 1 computer wired and some clients wireless, I want to have net-1 for my wired clients and net-2 for my wireless clients, but separate and using both networks the same ISP.
Thanks!!!

Go to the Setup page of the wrv210. On the sub-tab click on Vlan. Select enable on the Port-Based Vlan. Check the box of the desired vlan that you want to assign to the port and ssid.

How to create wrielesss vlan with diffrence configuration

how to create wireless vlans with different configuration in network?

Posted by WebUser ???? ?????????? from Cisco Support Community App

in this case we don't have enough budget t get WLC device....mybe use the autonomous ap....i use the linksys wireless routes as AP that connect to switch and create the VLANs 10 and VLANs 20 in the switch 2960, the switch connect to router 1841 that will ensure vlan connect each other.

How to search/Scan Vlan of cisco switch ports

Can any one tell me how i can scan/search vlans of cisco switch port through any monitoring tool (orion/solarwinds).
Consider this scenario as i have no access to switch and i want to know below things:
1-Vlans created on switch?
2-which switch port belongs to which vlan id?
Thanks

Hi,
You can do it only with hub in between and also please note that when sniffing with Wireshark on Windows the OS would remove VLAN tag so you may need to use Linux machine.

Creating a private/isolated vlan on Cisco switch

Hello
I have many Cisco switches 65xx, 37xx at my company with a lot of vlans already configured. I need to create a new isolation vlan that will not be able to communicate with my other existing vlans. We are setting up a NAC solution at my company and we want a vlan that we can send ports to if the computer or device is compromised and cannot talk or risk the existing network (other vlans). What is the best method to make this happen?
I have created VLANs in the past but this is my first dealing with private/isolated vlans and would be grateful for any guidance on how I should implement this.

So are you saying I should just create a new L2 vlan and not configure the vlan interface (which is at L3) for this new vlan so I cannot communicate with any of my existing vlans therefore isolating the new vlan?
Yes, without an SVI clients in that vlan cannot communicate with anything outside that vlan.
The only thing that wasn't clear was whether these clients should still be able to access the internet even though they couldn't talk to any other internal vlans. If they did need the internet, or any other remote network, then you would need an SVI but it sounds as though you don't want any external communication for these clients ?

Can't create VLAN's with Cisco Network Assistant

Hello everyone
I have a problem with my newest Switch, a WS-C2960X-48TS-L
Normaly I can programm all my Switches with Cisco Network Assistant. But now I have a problem with creating VLAN's. I can create them, safe them but after a refresh, all the new VLAN's are gone!
I updated the CNA to the newest Build 6.0 and updated the Switch to 15.2(2)E, but nothing helps!
Over the CLI I can do everything, but this is not a option for me! To programm sometimes a switch CNA is perfect for me! If it works!!
Thanks
Tobi

yes I can programm the vlan's over CLI. That's works. I have not tested this if its really works, but the VLAN's are programmed.
hmm I checked the STP / VTP settings with a second identical Switch, but there are no differents. Made a backup of one Switch and restore on the other One, but I'm still not able to create VLAN's.
however, I contacted my vendor today, he tell me that it shouldt be a problem to take back the switch.
Best regards
Tobi

How to create a VLAN on only one host?

Hi,
is there a way that a VLAN can be created on a specific host's vNICs rather than appying the VLAN to all hosts through an updating template?
I am kinda trying to get my head around UCS, I have alwats created vlans by creating the VLANs first and then modify the VLANs in an updating template, but in this case, only one host needs that VLAN.

Hi Max,
The only way to do this is if you unbind the service profile from the template (service profile template, and vnic template), but this means that you will need to keep track of the changes for this service profile separately as this service profile won't be part of these templates.
Note that you will still need to allow the vlan on the uplinks but you will be able to assign this vlan to the unbounded service profile.

Linksys WRT600N vs CISCO PIX 506E.... Firewall / Routing Performance

Hi:
I am new to the forum and was hoping to tap into some of your expertise. I have a Linksys WRT600N version 1.1 and I recently acquired a CISCO PIX 506E firewall. My question is what should I use as a firewall? Both have SPI etc. Should I:
a) Use the 506E as a firewall and use the 600 as a wireless access point, or
b) Use the 600 as a firewall and wireless access point.
Do both routers have the same firewall routing performance? I want to use the storage feautre on the 600N, but if I do that and use it as a wireless access point the 600 can't get the proper time from the Internet, so my time for newly created folders and files shows they are 10 years old.
Anyway, just thought I would post and find out what some of the experts thought and maybe someone from Linksys or CISCO. I know the 506E is discontinued and was manufactured around 2001 and the 600N is a new model.
(Edited subject to keep threads from stretching. Thanks!)

The PIX is a real firewall. The WRT has a firewall which mostly protects the router itself. People prefer to buy a "SPI firewall router" instead of a simple "router" even though the router firewall does nothing or little to protect the LAN. The only firewall configurations on the WRTs you can usually do is on the Access Restrictions tab. But that's usually all. The LAN itself is not protected by the firewall. You would notice this if you had a public IP subnet and ran it through the WRT: the LAN would be fully exposed to the internet. Some routers have a few functions like protection against denial of service attacks or similar. But even then this often filters only the traffic targeted at the router and not the LAN.
The common protection of your LAN you have on the WRT is because you use private IP addresses inside your LAN and the router does NAT. However, NAT is not a security mechanism but a mechanism to solve the problem that you can only have a single public IP address but want to use multiple computers, which is why you have to use private IP addresses. Current NAT implementations usually drop unsolicited incoming traffic because they don't know to which IP address in the LAN to send it to. But the notion of NAT is to deliver and to allow connectivity. This has nothing to do with security or a firewall.
Thus, if you want to use a real firewall use the PIX. On the PIX you can configure the traffic which is allowed to enter the LAN and which not. It is far superior in this respect to the WRT. However, as it is a older model, I cannot tell how fast the PIX is. You should be able to find the old data sheets of the PIX somewhere on the cisco website. They should mention the possible throughput. I guess it won't be an issue.
To me another point for the PIX are the VPN capabilities which allow you to securely access your LAN while you are on the road.
Of course, you must know how to configure the PIX correctly. It is a complex device and can be configured pretty much for anything you like. This means of course if you do it wrong you may end up with little or no security.
BTW, there are no people from linksys in this forums except the moderators (which may be from lithium). To hear from Linksys you have to contact Linksys support.

I could not send you the output either of the pix or concentrator because I did not get an error or a message that the tunnel will be established.
What can be wrong ?
Thanks for the replies

This sample configuration demonstrates how to form an IPsec tunnel from a PC that runs the Cisco VPN Client (4.x and later) to a Cisco VPN 3000 Concentrator to enable the user to securely access the network inside the VPN Concentrator.

Dual SSID (with dual VLAN) on Cisco AiroNet 1130

Cisco Community,
I need some major help in figuring out how to change our wireless setup. Currently, we have 2 Cisco AiroNet 1130 WAP's in the office that go directly into the 2 POE ports on our Cisco ASA 5500. These WAP's have 1 SSID and are using WEP for security. After demonstrating the flaws of WEP to my boss, he has agreed that we should use something more secure and I've suggested WPA. We want visitors to our office to be able to hop on our wireless but on a separate guest SSID with WEP.
I'd like the internal SSID to route to the ASA and take the default route to the internet (it will be our new fiber connection once it's installed in a couple weeks). The default route is whichever connection is working since our ASA 5500 will fail over when it detects an outage.
I'd like the guest SSID to route to the ASA and then go over our existing cable connection. This connection will be our backup once the fiber connection is installed. Since we won't be using it very often, but will be paying for it, I advised that we send all guest wireless traffic over this connection since 50/5 is plenty for guests.
I have no idea how to create a VLAN and implement it but I can generally figure things out with a little help. The current SSID (which will be the internal SSID) has no VLAN. We do currently have a few VLANS on our network, one for voice (.42) and one for data (.100) and the default (.0). What device to I create the VLAN on (Cisco 5500?) and how to I setup the WAP? I need very basic instructions to start and I'm also trying to do this without causing downtime if possible.
I've attached a diagram of what it should look like. Red indicates our internal network and Blue indicates the guest network. I can send screenshots as well.
Hope everyone is enjoying their holidays.
Thanks,
Cody

Creating VLAN

How is VLANs configured on a switch ? What are the parameters defined while creating a VLAN/ Voice VLAN ? Since switch operates on layer 2 switch, is it required to define vlans on router as well. This might be very simple and basics of networking. Need to understand to clarify my doubts.
Thanks
Feroz

HI Feroz,
VLAN is a virtual LAN. In technical terms, a VLAN is a broadcast domain created by switches. Normally, it is a router creating that broadcast domain. With VLAN’s, a switch can create the broadcast domain.
This works by, you, the administrator, putting some switch ports in a VLAN other than 1, the default VLAN. All ports in a single VLAN are in a single broadcast domain.
Because switches can talk to each other, some ports on switch A can be in VLAN 10 and other ports on switch B can be in VLAN 10. Broadcasts between these devices will not be seen on any other port in any other VLAN, other than 10. However, these devices can all communicate because they are on the same VLAN. Without additional configuration, they would not be able to communicate with any other devices, not in their VLAN.
Please find the details below:
Vlan on Switches:-
Two types of Vlan(Layer 2 - Layer3)
Layer 2 vlan:
config t# vlan
Eg:
Let’s say we wanted to create VLAN’s 5 and 10. We want to put ports 2 in VLAN 5 (Marketing) and port 3 in VLAN 10 (Human Resources). On a Cisco 2950 switch, here is how you would do it:
# vlan 5
#name marketing
vlan 10
name humanresouces
exit
int f0/2
switchport mode access
switchport access vlan 5
int f0/3
switchport mode access
switchport access vlan 10
Layer 3:
conf t# interface vlan 2
followed by ip address.
Please find below link which explains complete info on VLans.
http://www.cisco.com/en/US/docs/switches/lan/catalyst2950/software/release/12.1_9_ea1/configuration/guide/swvlan.html
2- Vlan on Router:
A vlan configuration on a router is slightly different than on a switch. On a switch, you would create the vlan and then the routed vlan interface.
On a router you tie a vlan to a subinterface. You need to create the subinterface and then do the encapsulation dot1q command. This command basically assigned the vlan to the subinterface. In this example, there are 2 vlans, vlan 100 and 201. On the eth 0/0 interface, I created two subinterfaces. fastethernet0/0.100 and f0/0.201. Notice that I matched the subinterface number with the vlan ID. You do not have to do this, but it is a best practice and really helps you as the administrator keep things organized. So, under f0/0.100, there is the encapsulation dot1q 100, which basically binds vlan 100 to subinterface f0/0.100, then I assigned the IP. The same is for the other subinterface. So the router is trunking two vlans on its f0/0 interface, vlan's 100 and 201.
interface FastEthernet0/0
no ip address
speed 100
full-duplex
interface FastEthernet0/0.100
description test Network
encapsulation dot1Q 100
ip address 192.168.102.1 255.255.255.128
no snmp trap link-status
interface FastEthernet0/0.201
description Office
encapsulation dot1Q 201
ip address 205.127.102.129 255.255.255.128
no snmp trap link-status
Kindly go through the same and reply back if you need any clarification on the same.
