RV016 VLAN support
I was looking at the RV016, thinking that it might be perfect for a situation I have, and there seems to be many references in various forums for simpleVLAN support for this model, i.e. designating a range of physical ports to a VLAN. But the documentation on Cisco's site for this model makes no mention of VLAN support at all. Has it been removed from this model for some reason? Was this a feature on the pre-merger Linksys version that is now gone, or is the feature undocumented for some reason?
Hi Daniel,
You need to configure multiple subnets - in order to have 2 IP ranges.
Thann you need to chose different VLANs on 2 ports of RV016 (Port Management > Port Setup) - for example VLAN1 on port1 and VLAN2 on port 2 - thus you will separate the trafic on the 2 ports. You can connect your LAN on port1 and the AP for guest wifi on port2. Both subnets will have access to i-net, but not one to each other.

Kremena

I recently bought an 851 only to find out afterwards that it only supports 1 VLAN when I needed it to support at least 7. The documentation on VLAN support seemed pretty buried.
Does anyone know if there is an easy way to find out how many VLANs each router model supports? I dont' want to make the same mistake again, and I can't seem to find what I'm looking for by combing through the data sheets for each model.
Thanks!
Sorry, I meant to post this in the routing and switching forum and I can't figure out how to delete the thread.Hi
A maximum of four VLANs are supported on the Cisco 870 Series with the plus feature set (Advanced IP Services/Advanced Enterprise Services) Cisco IOS. The Cisco 850 Series only supports one 802.1q VLAN.

[Q]: OracleVM VLAN Support with same subnets
Can I create OracleVM Network VLAN pool that would allow for two vlans to use the same network topology or segment. Meaning, does the VLAN know how to tag the vlan I created to know which vlan the traffic came from and route back to the proper vlan. For example, VLAN1 - 192.168.1.0 and have any machines assigned to this vlan to only communicate with other machines on VLAN1. And have VLAN2 on the same network defined private segment with 192.168.1.0 network. BUT, is OVM aware of the tagging of VLAN1 and to route information back to the proper VLAN?
TIAVLAN tagging is independant - and of course must be, since it belongs to layer 2 of the OSI model, of the IP network that is run on it. You musn't confuse the network switches PVID (aka untagged VLAN support) which tagg an incoming packet on a switch port to a specific VLAN.
If you configure VLANs in OVM your're absolutely free to use whatever ip network you want on it - the traffic will stay seperated, since your're running it on a - although virtual - separate LAN. -
Hi,
I've hacked vlan support into the arch init, at least, I haven't been able to test this really, I have no vlan capable switch... This might be of use to some people, or may not... (it also includes my bonding support)

Good luck,
Pascal de BruijnHow do you have your h-reap setup... how many ssid's for example? If dhcp is local, for all ssid's, then all ssid's must have local switching on unless clients will get tunneled back to the wlc and obtain an ip address there. When you say... turn on and off vlan support, you talking about the native vlan setting in the h-reap ap?

hello, i have the cisco router (871) and when i try to create another vlan (another than vlan1 wich is default), i get the following message:
"vlan can not be added. Maximum number of 1 vlan(s) in the database"
with the command "show vtp status" i obtein:
"maximum vlans supported locally:1"
how can i change this???
i have read that i have to update my firmware and add a new flash card, is it true??
thank you very muchi would say try updating the ios image, i have c870-advipservicesk9-mz.124-6.T.bin and i have 8 possible vlans. also check your VTP version and post what it is

REQ: VLAN Support for Access Connections
hi,
i would like to see VLAN support for access connections. i have a thinkpad t400
cheersVPN-User wrote:
What can be understood wrong with "VLAN support in Access Connections"? If you want to know what VLAN stands for, just google.
I know perfectly well what VLAN is since i work with networking every day and that's why i asked because i still cannot understand what maharaja mean by AC VLAN support. I asked because i might be able to help since i use VLAN with AC a lot so don't understand exactly what he find to be missing. I'm pretty sure what he is looking for is already there.
Not sure why you felt it necessary to post such a arrogant reply which is not helpful for anyone, but asking for VLAN support could be several things so that's why some further explaination would be necessary to understand what exactly the request is about. I guess you made you point to tell everyone you know what VLAN is, but then you should also realize that the question in the first post might need some further explanation since the feature might already be there.

VLAN Support at routers and switches
is there a table with howmany VLANs each of cisco routers and switches can support.
its not always written at the product data sheet.hi
Do find the details for 1800 ISR series router..
802.1Q VLAN
A total of eight VLANs can be configured to segment a network and offer additional security and separation of network traffic.

Have the Cisco RV016. One single internet access on WAN1. LAN1 connected to a 24-port ethernet switch. Connected to LAN8 is our customer wifi access unit. To separate the public wifi, I set LAN8 to VLAN2. LAN1 is set to VLAN1. How can I set this router to let me access from a computer on the LAN1 (VLAN1) to the Wifi Unit on LAN8 (Vlan2). This configuration has successfully kept the public out of the company network, but has resulted in no access for me to the wifi unit for administration from my desktop.
Thanks,
MikeThis unit supports port base vlan, it won't route the vlan's between. The router does not support 802.1q nor does it support SVI.

Hi Cisco experts,
My name is Kumagai and I need your expert opinions below.
I am trying to configure one VLAN1 support multiple network segments as below.
(this should be a very straight forward configuration and should be OK, I think ? )
interface Vlan1
ip address 172.30.0.0 255.255.128.0
ip address 172.30.31.253 255.255.254.0 secondary
ip address 172.30.61.253 255.255.254.0 secondary
ip address 172.30.71.253 255.255.254.0 secondary
ip address 172.30.4.253 255.255.255.0 secondary
The only issue that is eating me is the above network segments are using HSRP too
and I am not sure is this possible with a combination of VLAN1 supporting multiples which are
further supported with HSRP settings in Cisco environment.
!example of HSRP:
interface Vlan4
ip address 172.30.4.253 255.255.255.0
no ip redirects
standby 4 ip 172.30.4.254
standby 4 priority 105
standby 4 preempt
<<< what will happen if I add the HSRP configuration as below into the above VLAN1 with multiple Network segment ??)
I would like to summarize my "Combined" configurations as below but I need your expert opinions on
whether the configuration below is workable without any problem ??
Or it is a total flop because Cisco does not support the configuration below !!!
interface Vlan1
ip address 172.30.0.0 255.255.128.0
ip address 172.30.31.253 255.255.254.0 secondary
ip address 172.30.61.253 255.255.254.0 secondary
ip address 172.30.71.253 255.255.254.0 secondary
ip address 172.30.4.253 255.255.255.0 secondary
standby 30 ip 172.30.31.254
standby 30 priority 105
standby 30 preempt
standby 60 ip 172.30.61.254
standby 60 priority 105
standby 60 preempt
standby 70 ip 172.30.71.254
standby 70 priority 105
standby 70 preempt
standby 4 ip 172.30.4.254
standby 4 priority 105
standby 4 preempt
Thanking you in advance !!!!!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.

i have two sites required to be connected using wireless 1300 bridge but There is 30 VLAN and i think that 1300 series support 16 VLAN only is it right ?. Please advice me if 1300 support more than 16 VLAN how to conigure it if not support then which mode support more VLANS.
Thanksbuy a pair of routers, and use the 1300's to provide the link between the routed interfaces, then you only have to pass one VLAN between them.
Then, if you're still desperate to get those specific VLANs to the other site, I believe you can do some magic with your routers to tunnel them inside your routed link. -
Cisco 38xx: VLANs support
Sirs:
What is the maximum number of VLANs allowed in the in-built GEth interfaces? It depends on IOS version?Hi,
The 3800s platform will allow you to configure any of the VLAN IDs in the range of 1-4094. The number of actual sub-interfaces that you can create will be limited by the number of Interface Descriptor Blocks (IDB) supported by the platform.
Quoting from CCO: "An Interface Descriptor Block (IDB) is a special control structure internal to the Cisco IOS software that contains information such as the IP address, interface state, and packet statistics. Cisco IOS software maintains one IDB for each interface present on a platform and one IDB for each subinterface."
The number of interfaces that you can have is limited by the IDB limit for the platform and of course, memory available.
Therefore, while you can theoretically configure 4094 ethernet sub-interfaces, in practice that is not achievable.
Now, the 3825 supports a maximum of 1200 software IDBs and the 3845 supports 1400. So that is what you are limited to.
To find out how much your platform supports, issue the 'show idb' command.
Pls do remember to rate posts.

Private VLAN support on actual HW
Hi all,
I'm currently thinking about a private Vlan based solution for a special demand.
Now for my initial investigation i need tio have something like a Pvlan HW support matrix.
Means I'd like to know which switches in cisco portfolio supporting PVLAN's.
Additional I'm wondering cause most of the PVLAN documentation relative old.
How about PVLAN support. Is Pvlan on Access switches still (and in future) featured by Cisco?
thanks for your comments
DieterHi Dieter,
You could see this detail using Cisco Feature Navigator tool which is avilable on the cisco web site.
1. Go to below site
