WRVS4400N VLAN Question

On what vlan, if any, is the wireless port configured? I can assign vlan 1-4 to any LAN (hardwired) port to isolate traffic, but not the wireless port. Do wireless packets go to vlan 1 by default and no other vlan #'s? I want to keep wireless traffic out of specific or all LAN ports, yet allow wireless access to the WAN port. Also, how is external VPN traffic routed if vlan is used? To what vlan is the VPN connection assigned? Kan't find any help in the documentation or on the web. The ability to isolate traffic is one of the main reasons for purchasing this product. THX

From what I know, although the WRVS4400N has support for port based VLAN setup, it does not give you the option to set different DHCP addresses for each of the 4 VLANS.

The old native vlan question....

Topic came up during troubleshooting a 3524XL sw.
I think my understanding of the native vlan concept is wrong.
I thought on a trunk port (Cisco device) that any packet transversing a trunk link (dot1q trunk that is) has a vlan tag applied on the egress port. As an untagged packet arrives on the port (prior to being sent out over the trunk), its is tagged with the native vlan (if its not assocated with any other vlan), then sent out the (egress) the trunked port.
But lately I have been reading that
"A native vlan is the untagged vlan on an 802.1q trunked switchport. The native vlan and management vlan could be the same, but it is better security practice that they aren't. Basically if a switch receives untagged frames on a trunkport, they are assumed to be part of the vlan that are designated on the switchport as the native vlan. Frames egressing a switchport on the native vlan are not tagged. This is the definition however more recent switch software often will allow you to tag all of the frames, even those in the native vlan. This gives some added security and allows the CoS bits to be carried between switches even on the native vlan. Let me know if you need further clarification."
From : https://learningnetwork.cisco.com/thread/8721
So this tells me that you can have a packet transversing a dot1q link w/o a vlan tag...then when it arrives on the other end its put in the vlan that is on that native vlan question. Is this correct?
If so, and a packet can transverse a trunk link w/o a VLAN tag applied, how does a sw detect (ingress) a native vlan mismatch?
Thanks!

Hi,
It's correct, the native vlan is not tagged by default on the trunk link but some platform can make you tag all traffic though even the native vlan.
The native vlan mismatch is detected through cdp.

WRVS4400N VLAN trunking question

Hi all,
I just got a SRW224G4 today my main objective is to trunk 30 VLAN(s) to my WRVS4400N for interVLAN communication. So far I set G1 on my SRW as a trunk port and linked it to port 2 on my WRVS4400N (which is also set as a trunk).
So far no good when I go into LAN settings I do not see an option wheree I can set DHCP addresses or gateways for these VLAN(s). Is this even possible with the WRVS4400N I meen if Linksys is going to provide a small business solution atleast their equipment should support VLAN trunking with each other.
If anybody knows the solution to this please let me know.
Cheers

From what I know, although the WRVS4400N has support for port based VLAN setup, it does not give you the option to set different DHCP addresses for each of the 4 VLANS.

Wrvs4400n vlans/ssid/dhcp issue

Hi all,
it will be great if someone will help me with my problem.
the problem is : our wrvs4400n wifi router configuration.
network description: we need 2 separated wifi networks one for guests and one for internal access, and i configured them on router, and also configured each one of them to different vlan, guests to vlan 200 and internal use default vlan 1.
vlan 1 configured as dhcp relay and its working pritty well.
vlan 200 configured as dhcp and the problem begins here.
somehow on vlan 200 i get dhcp from our externam dhcp server,
wrvs4400n conected as follow> lan port1/vlan 200 connected to firewall port(configured as vlan 200) and lan port 4/vlan1 conected to our main switch wich connected to firewall also.
i guess that my knowlege in networking its not so good......
how can i prevent from our internal dhcp to comunicate with vlan 200 ,
any help will be very appreciated.

Hi Rich,
You cannot have different L3 VLANs sharing the same subnet.
Each VLAN must have it's own subnet and then you have a routing device routing between both VLANs.
You should have a DHCP pool also for VLAN 111 configured on the DHCP server.
Even if you have ip helper address configured and this should be done on the VLAN111 interface of the switch, you still need a DHCP pool for VLAN 111 because the DHCP discovery is coming on VLAN 111.
Please take a look into this document:
http://www.cisco.com/en/US/tech/tk722/tk809/technologies_configuration_example09186a0080665ceb.shtml.
Here it explains how to configure 2 ssids on 2 vlans and dhcp pool (on the switch itself) for each vlan.

WRVS4400N VLAN support

Hi all,
I recently purchased a WRVS4400N for my small lab network. I have a question in regards to how the VLANing works on this device.
My objective is to create 4 VLAN's
This is how I want my addressing to look like
VLAN 1 (Servers), Subnet: 172.16.0.0 /26, Gateway: 172.16.0.62
VLAN 2 (IT), Subnet: 172.16.0.64 /26, Gateway: 172.16.0.126
VLAN 3 (Marketing), Subnet: 172.16.0.128 /26, Gateway: 172.16.0.190
VLAN 4 (Design), Subnet: 172.16.0.192 /26, Gateway: 172.16.0.254
I wanted to know if this is possible on the WRVS4400N. Going through the router setup I do NOT see an option where I can assign an IP address range per VLAN. The only DHCP options I see is when I go iunto the LAN settings under Setup. It seems that I can only assign a spefific address range per subnet not by each virtual lan.
If anybody knows how to do this any help would be greatly appriciated!
Cheers
Graham R

The demo ui for the routers on the link you have mentioned are already outdated. Although the RVS4000 ui looks similar to that of WRVS4000N, there are still some features that are yet to be found on the latter.
On the RVS4000 Firmware v1.1.09 Release Notes, one of its features included:
*DHCP Server (in the Setup->LAN page) supports multiple subnets, once multiple VLANs are created.
I have not yet tried to configure vlan on an RVS4000 router since I do not have one, unfortunately . At the moment I am using an RV042.

SG300-10 VLAN Questions

My apologies if this has been asked before, but I have some questions regarding the setup of my new switch and network. I have never worked with switches before, so this is quite a learning experience. The picture above describes the current layout of my network. Here is how I have tried to set it up, so far.
VLAN 1 [Ports 1-4, Untagged, Trunk] (172.16.1.1/24)
Workstation A (Wired)
172.16.1.2/24
Server B (Wired)
172.16.1.3/24
VLAN 2 [Ports 5-8, Untagged, Trunk] (172.16.2.1/24)
Server C (Wired)
172.16.2.2/24
Server D (Wired)
172.16.2.3/24
Server E (Wired)
172.16.2.4/24
Server F (Wired)
172.16.2.5/24
VLAN 3 [Ports 9-10, Untagged, Trunk] (192.168.1.1/24)
Laptop G (Wireless)
DHCP via Router
Laptop H (Wireless)
DHCP via Router
Laptop I (Wireless)
DHCP via Router
Wireless Router
192.168.1.254/24
Now, my goal is to have all 3 VLANs be able to talk to each other but also have VLAN 1 access the internet, through the wireless router. In the future I would also like Server B to be able to expose services (http & ssh) to the outside. VLAN 2 shouldn't have internet access at all. I know I can add static routes to the wireless router, if need be. All three laptops, can access the internet through the wireless router, without any problems.
So my questions are:
1) Is there anything inherently wrong with the design of this network? If so, what could be changed?
2) Is VLAN 3 really necessary?
3) What would I need to do, to get the 3 VLANs communicating with each other?
4) What should the gateway be, to get VLAN 1 internet access?
5) What would I need to do, to expose Server B services to the outside?
6) What static routes do I need to add?
Thanks in advance!
   Jer

Hello Jeremy,
Thank you for your interest and patience.
You are on the right track here. However, several important changes must be made. Consider the following concepts:
The concept of a native VLAN. The link between the router and the switch must be part of VLAN 1. Otherwise, information from the router will not be distributed correctly on the switch due to the current PVID of 3.
The VLAN IP Interface (VLAN IP Address) identifies the subnet for the VLAN. Therefore, thinking of the switch as a router, you are correct that the default gateway for each client should be the respective VLAN interface on the switch. The switch will automatically route between directly connected IP Interfaces and their subnets.
However, in order for your clients to get to network that the switch doesn't know about, (the internet), there must be a default route to the router.
Additionally, in order for the router to forward information from the internet back to the VLANs on the switch, the router must know how to reach the different VLANs.
The folloing linked figure (Fig. 1) describes an appropriate sample setup. See here.
In this scenario, a SG300-10 is configured with 3 VLANs:
VLAN 1 - Default VLAN, used for management - 192.168.1.x/24 - Ports 9-10 - 1U - Trunk Mode
VLAN 2 - Servers - 192.168.2.x/24 - Ports 5-8 - 2U - Trunk Mode
VLAN 3 - Workstations - 192.168.3.x/24 - Ports 1-4 - 3U - Trunk Mode
VLAN 1 is used to communicate to the router. Therefore, the following default route must be added to the switch's configuration:
ip route      0.0.0.0      0.0.0.0      192.168.1.1
The switch will automatically build the routes between the VLANs local to the switch. Visualize Server C going togoogle.com. Its IP address is 192.168.2.2. Its default gateway should be the VLAN 2 IP Interface on the switch (192.168.2.254 in this example). Because the default route is configured, the switch will forward the internet request to the router. The router will then forward the request to your ISP out the WAN where it will eventually reach Google.
However, when the request comes back into the router, the router must know to route it to the 192.168.2.x subnet. So, in order for this to work, routes that accomplish the following must be configured on your router:
Subnet IP               Mask                    Gateway                                              Interface
192.168.2.1             255.255.255.0        192.168.1.254 (SG-300 IP Interface)         LAN
192.168.3.1             255.255.255.0        192.168.1.254 (SG-300 IP Interface)         LAN
As you have already discovered, there are several limitation to using a router that does not support 802.1Q tagging. Chiefly, your clients will not receive either DHCP or DNS automatically from the router. To mitigate this, you can do either of the following:
Run a DHCP server with multiple DHCP scopes on a device connected to your switch. You can then use Option 82 on the switch to route DHCP requests and DNS info between VLANs on the switch.
Statically configure IP and DNS information. You could enter Open DNS Servers or Google's DNS servers on your clients.
Ideally, you would want to use a router that supports 802.1Q tagging. In this figure here (Fig. 2), you can see the VLANconfiguration page for a Cisco RV180W, a very capable and affordable small business router that I highly recommend. Port 1 on the RV180W is configured as a trunk port and carries VLANs 1-3 to the switch. The clients automatically receive IP addresses and DNS information from the correct DHCP pool on the router.

A very odd VLAN question -please help

Hi,
We have two subnets 10.1.1.0 and 10.1.2.0 and these subnets are phisically separated. we also have two VLANS, VLAN 2 and 3, please think of the VLAN 2 as the default VLAN 1. strenge, it has been like this when I took over. there is no trunking between these two VLANS. 10.1.1.0 is the main network and all the servers and users arfe on it and 10.1.2.0 is a Dev environment and some development severs are on it.
I have given an IP address from the maon subnet i.e. 10.1.1.0 to a switch which is used for Dev environment on its SC0 and have assigned it to VLAN 2 but the rest of the 10.1.2.0, i.e. the Dev environment is on VLAN 3. from the main network I cannot ping that IP address (naturally) and I don't know how to build on what we currently have without making major changes and build over time as transparant as possible.
I am sorry for this very long expalanation.
I guess I need to know if I can make trunking between these two VLANs, i.e. VLAN 2 (main 10.1.1.0) and VLAN 3 (Dev environment 10.1.2.0) with out needing a router? of if I need a router, how? so that I can build upon it over time.
well, I have given an IP address from main subnet from VLAN 2 to a swotch which is for VLAN 3 or Dev environment!!! I really didn't know how to do this in order to make it as trasnparant possible to others since I am not in charge of the AD and the servers.
Please forgive me for my somehow vague explanation and I hope I could have made a question.
Thanks,
Masood

Hi and thanks for responding. Almost all my switches are L2/L3 Cisco CAT switches with two 3560 at the edge with knowledge of public network located between my two border routers and my Firewalls. My main switch is a Cisco CAT 4510 R with is a layer 2 and 3 switch with Cisco IOS and a few 3550s and 3512s around. I also have two CAT 4006s with CAT OS but these aren't my current concern as I know that I need to either use one of these swithes or a router to route between my VLANs. I do have a Cisco Router, a 2621 as my main router with its fa 0/1 is used for my two mian subnets (servers, devices, and users are on these two subnets 10.1.1.0 and 10.1.4.0) and the DHCP server is givng out IPs out of these two private subnets. the other interface on this router fa0/0 is used for 10.1.2.0 which is totally isolated subnets with a bounch of servers on it called Dev Environment. The AD guys want it this way.
Ok, now, when I take over this network I realized that those people who were looking after this network had created two VLANs, VLAN 2 (acting as the default VLAN 1 actually and used for managemnt of devices too) and VLAN 3 (VLAN 3 is for 10.1.2.0, i.e. the DEv Evironment, so bacically all of my devices, servers and users are on VLAN 2!!! and no trunking.....
I have provided a Diag of my network topology.
what I need to do is to find the best way to create a few more VLANs on my main network (10.1.1.0 and 10.1.4.0) and put all the servers on one VLAN; say VLAN 2 and few other segments and ten start to route between them by trunking. My problem is that the AD guys do not want to get involve and do not want (one of them my boss) to do IP renumbering so i need to do this at the L2 (by MAC addrss may be) and then use the router or (I can upgrade my main router to provide more interfaces with more mem and processing power) and use t to route between VLANs. this router is also used to connect us to a remote office where we have our Web Servers hosted via a T1 point-to-point as we are an online business so I need to be very carefull with this mission and have all the server and web Servers at this locations and my remote locations (10.5.1.0) on a same VLAN and then user on different VLANs by segmenting departments.
Now, you see my delema and the challange that I am facing. how this can be done slowly and gradually. first adding one more VLAN put all the servers on it (also, back interfaces and clustering of servers in mind) and users on another, then, start trunking and see how it works. if all goes well then I can start creating more VLANs and that would be the easy part and point them to the trunk Interface / Link.
Your thoughts will be greataly apreciated.
Thx,
Masood

WRVS4400N VLAN Configuration

I've got a WRVS4400N small business router and need to configure it so that the WAN has internet access but the LAN does not. I've tried messing around with VLAN and internet access policy settings, but it would require that I have the MAC addresses for every machine I want to block from the internet. Is there any way I can configure to router to provide IP addresses to the devices on LAN but block internet access?

On the same page in Internet Access Policy where you put MAC addresses to filter, you can specify the range of IP addresses instead. Then you can configure the schedule to be blocking Everyday for 24 Hours a day.

WRVS4400N VLans

I have a WRVS4400N that broadcasts two different SSIDs. One is a public network and the second is a private network. Right now, both SSIDs are pulling from the same DHCP server, but I would like to separate the public from the private. How can I separate these SSIDs by vlans? I can't seem to get the vlans to route to separate ports.
This is my vlan settings. I have two DHCP servers right now. One is in an isolated network plugged into Port 3 of the WRVS4400N. The other is on the production network, plugged into port 1 of the WRVS4400N.
For some reason, whenever I connect to SSID Public, it won't pull an IP from the DHCP on port 1, it only pulls it from the one on port 2.
I know there is three SSIDs here, the Static one is going to be the same network as the EMS one.
SSIDs:
VLans:

Vlan & Inter Vlan question

Here is my network layout:
I have a cable modem connecting to a Linksys WRT54GL (DDWRT) router. Port 1 on the WRT54GL is connect to port 01 on the SG300-10 switch.
On the SG300-10 I've created two Vlans (Vlan 30 & Vlan 40). I assigned ports 3 & 4 on the SG300-10 to Vlan 30 and ports 5 & 6 to Vlan 40. Vlan 30 has the IP Address 10.10.30.1 and Vlan 40 has an Address of 10.10.40.1. The default Vlan (Vlan1) has an Address of 10.10.20.2. The default gateway (WRT54GL router) has an Address of 10.10.20.1. I have also enable DHCP relay on the switch and enter the command "ip routing". My question is on either vlan if I wanted to setup static addresses for clients would I use the 10.10.20.1 (WRT54GL) address as the default gateway? Also, what additional configurations do I need to make for the Vlans to be able to talk to each other and be able to access the internet?
Thanks,

Van,
Thanks for the reply. The SG300-10 is in layer 3 mode. I have configured the DHCP server accordingly. Here is my setup:
                   cable modem
                          |
                          |
                   linksys wrt54gl (10.10.20.1)
                          |
                          |
                   sg300-10 Vlan1= 10.10.20.2 (manage)
                                  Vlan30= 10.10.30.0 /24 (GW= 10.10.30.1)
                                  Vlan40= 10.10.40.0 /24 (GW= 10.10.40.1)
You said that for inter-Vlan to work I need to set the clients GW to the switch. Would that be the Vlan's gateway for clients in each vlan? For example if a client was in vlan30 their gw would be 10.10.30.1?
The clients are not able to access the internet from the vlan. How would I configure the static on the switch for the vlans to be able to access the internet? Would this work: ip route 0.0.0.0 0.0.0.0 10.10.20.1?

Private vlan question

I am replacing a standard set of switches out with ones that can support PVLAN's. All our switches currently have their ip address on vlan 1 and that is the subnet which the default gateway resides. The second switch acts as a redundant switch and will need the same vlans as the primary. Currently they are etherchanneled together. I want to setup a single private vlan with one isolated vlan and several community vlans. My question is where do I put the IP address? Do I still setup a vlan 1 interface as I have done all along? Or do I put the addrss on the primary private vlan? And I assume I will need to setup a trunk between the two switches, vs. etherchannel?

Private VLANs provide Layer 2 isolation between ports within the same private VLAN. There are three types of private VLAN ports:
PromiscuousA promiscuous port can communicate with all interfaces, including the community and isolated ports within a private VLAN.
IsolatedAn isolated port has complete Layer 2 separation from other ports within the same private VLAN except for the promiscuous port. Private VLANs block all traffic to isolated ports except traffic from promiscuous ports. Traffic received from an isolated port is forwarded only to promiscuous ports.
CommunityCommunity ports communicate among themselves and with their promiscuous ports. These interfaces are isolated at Layer 2 from all other interfaces in other communities or isolated ports within their private VLAN.
PVLANS are also knows as secondary vlans, they are always associated to primary vlans so they can communicate to other devices outside their subnet through the default gateway. The management ip address or sc0 if it's CAtOS will always be in primary vlan or if native IOS and it's interface vlan it will always be the primary vlan. so, to answer your question, the management ip address will be in primary vlan.
You cannot use the inband port, sc0, in a private VLAN.
Note: With software release 6.3(1) and later releases, you can configure the sc0 port as a private VLAN port; however, you cannot configure the sc0 port as a promiscuous port.

IPS VLAN question

I am configuring an IPS 4260 in promiscious mode, and have a question about VLAN assignment. Does the sensing interface need to be in the same VLAN as the switchport you are spanning? Also does this port need to be a trunk?
Also If you want to log traffic only and not issue resets, do you just leave the default or do I need to switch anything off?
Thanks in advance!

Hi Networker99,
As long as you aren't using the "encapsulate replicate" command on the SPAN session sending the traffic to the sensor, the traffic will be copied without VLAN tagging information and no additional configuration on the IDS side should be necessary.
If you want to prevent TCP resets you should either designate an unused port as an alternate TCP reset interface for the promiscuous sensing interface or, alternatively, create a simple Event Action Filter to remove the "TCP Reset" action from all signatures on the sensor.
Best Regards,
Justin

VTP Vlan question

Dear,
This question has been bugging my mind lately, say you configure a switch to put it inside a VTP domain. Let's say the access vlan has to be 8 and voice 10.
If you preconfigure the ports the switch will auto create the vlan locally to the switch, but when you put in a VTP domain as a client, will it overrride the VLAN's you created.
Since if you already made the ports a member of vlan 8, and vlan 8 also exists in the VTP domain you will insert the switch in, will it just override your switch settings?
Kr,

I believe VTP won't override the actual port VLAN setting, but it should override the switch's previously defined VLANs.
In your example, the ports in VLAN 8 would still be in VLAN 8 as it's also defined to the VTP domain, but suppose VLAN 8 wasn't. In that case, your VLAN 8 ports wouldn't extend across any trunks, and they might no longer function as a VLAN within the switch itself.

WRVS4400n VLAN on the wanside

Hi,
Been trying to figure out howto create VLAN's on the WAN port of the WRVS4400n. Is this even possible with the factory firmware?

Dear Ankur
thanks for your attention
I do according to what you say.it means that I upgrade the ios to c1700-sy7-mz.123-14.T3.bin (ip plus feature) ios ,but unfortunately i could not set vlan on subinteface ,i config like this:
#conf t

%unrecognized command
could you pls tell me?
thanks

RV180 VLAN Question

My plan is to use VLAN1 for the internal private network and VLAN2 for free public wifi. My question is can I use a PC on VLAN1 to configure/manage my access points? There are no dedicated PCs on VLAN2.
Sent from Cisco Technical Support iPad App

Hi Terp,
I just finished setting up my RV180 with 2 VLANs: VLAN1 and VLAN5. VLAN1 is the management or default VLAN; while VLAN5 is my wireless guest VLAN.
My VLAN1 is 192.168.1.1. I have set all of the gateway settings according to our companies outside provider (phone and internet). The DNS settings are completed for both primary and secondary servers.
VLAN1 is where all our data files and office specific stuff is located. VLAN1 can access servers, users, and internet.
Under Networking>Multiple VLAN Subnets>
The DHCP Server for VLAN1 is set to NONE.
My VLAN5 is on ip address range 10.0.0.100-254/255.0.0.0. I have the DHCP Server set for this VLAN.
I did this so I did not get confused when checking Ipconfigs and now my free wifi users are clearly identified.
I am using a Cisco WAP321 as my access point. I have this hard wired to port 4 of my router. I do have a managed switch, but it is only on VLAN1 and therefore does not enter the equation.
I use a static ip address for my WAP in the 192.168.1.xx range. IPv4 Network Settings
I made sure under Wireless>Networks I made sure I have both VLANs with the same names and for VLAN1 I use the same security key as on the router.
Also I have Enabled Untagged VLAN on VLAN1 and Management on VLAN1.
I have DNS proxy enabled, BUT because this unit has a static ip address, I have to set my DNS server settings! This kept my guests from getting internet access for a few days. DON'T FORGET THIS
Anyway, everything works perfectly now.
Hope this helps.
