Airprint across VLANs

I have a WLC 5508 controller in my environment. I'm trying to use AirPrint to attach and print to a Xerox device on a different subnet. If I statically assign an IP address to the Xerox device on my WiFi subnet, I can print to it. How should I configure the WLC and/or my Catalyst 4500/6500 switches to allow AirPrint across VLANs?

Refer the guide :

SGE Series - Multicast Across VLANs

Does anyone know if the SGE series switches support multicast across VLANs?
If so, how do you configure it?
I have IGMP snooping enabled globally and for each VLAN.
Bridge multicast filtering is enabled as well.

Yes, the sg300 can, and yours probably can too. It's either the settings or the application. What are you trying to accomplish with the multicast over vlan? I had a situation where I was trying to get a DNLA tv to find a DNLA media server (Dnla uses multicast broadcasts for discovery) on a different vlan/subnet. While multicast across vlan worked, the Samsung tv would only look for media servers on its own subnet, regardless of the multicast. You may be facing some limitation of your application, rather than the switch. How about you post some screenshots of the multicast config, then generate some multicast traffic on one vlan and use wireshark to see if you can see it on the other.
Best,
David

NetInstall across vlans

I've just migrated from 10.7 to 10.8 Server. While mosrt of the services are running well NetInstall is being a pain in the neck..
In 10.7 the server had a static address assigned to the Ethernet pot and also had a VLAN with a static address. With this setup I was able to NetInstall any mac on that VLAN.
I've done the same with 10.8 but I can't NetInstall any Macs that are on the VLAN. Also the NetInstall Service only lists Ethernet as the avalible interface.
Has anyone managed to get NetInstall working across VLANs?
Thanks

We have this working just fine at my company. What we had to do was politely ask the Network Admins to add the IP of our server to the Helper Address list on the switches and routers. It only needs to be added to the first network device that is subneting the network that the client is on. (could be switch or router, most likely not a hub)
The Helper Address list is used for various discovery protocols, DHCP being one of them.
What this does is when the client is looking for the server, the switch/router takes that request and knows that at xxx.xxx.xxx.xxx (the server) there might be a device to help the client and passes that request on to the server on the other part of the network. So for every subnet of computers that needs access to the server you must add the IP of the server to the first device that divides that subnet.
sidenote DO NOT add the IP of the server to the Helper list for the subnet it is actually on, only for subnets that the server is NOT ON. This one drove me crazy for diskless booting. The server ends up getting the request from the client twice. Network guy got overly excited when he was helping us.

Remote Management across VLANs

I can remote manage fine on my VLAN. The workstation on another VLAN did
register its IP address under the Network Address. However, when I try to
remote manage across VLANs it does not get past Authentication.

Bonjour multicast across vlans?

We have Linksys SRW2048s and i'm wondering if anyone here has any experience configuring the Multicast options to allow iTunes sharing across VLANs.
Thanks,
Joel

You are asking the wrong question. Bonjour is how iTunes advertises it availability (daap.tcp) on the local LAN. However, even if you managed to see those advertisement on a remote LAN, iTunes also is programmed NOT to service any requests originating from outside of it local LAN (otherwise people could share their music across the Internet.) So, Bonjour advertisements is only half the story.
If you really wanted to accomplish this you'd need to:
1) have a proxy on the local LAN with iTunes to access the iTunes daap share.
2) simulate the Bonjour advertisement on the remote LAN to point to that proxy.
I made this work once with router port forwarding and a program called Rendezvous Proxy -- because my home network used to have the wireless on a separate VLAN for security. However, the hassle of separate segments with Bonjour, etc., eventually just led me to flatten out my network into a single broadcast domain.

Solution to use Airprint across subnets wired/wireless

A lot of companies are trying to figure out how to setup airprint to print
in the workplace, wired+wireless across subnets.
We finally figured it out with some DNS magic and a CUPS server.
I have documented the solution at a live document hosted at
http://sites.google.com/site/iwastepaper/
Hopefully it helps a few folks.
<Edited by Host>

You will want to make sure your APs can route from where ever you install them to the WLC managment address.
How APs find the controller can happen a few different ways:
1) DNS A record
2) Layer 2 broadcast (which you seen already)
3) IP Route Forward
4) DHCP Option 43
5) Manual Prime the AP
Most folks lead with option 43.

if you check the config guide you will explain the other processes.

Unable to communicate with time clock across VLANS

I have a situation where i am installing SGE2000Ps to replace my old switches and configuring VLANS. The time clock will not communicate across the VLANS. If I unplug the network cable and plug it back in I will get two successful pings. If i use a PC configured with the same network settings as the time clock and plug it into the port for the time clock it communcates fine. Have any one come across this problem?

Hi Wayne,
Thank you for contacting Cisco Small Business forum.
I am sorry that you experience this issue.
I have a question for you. What is providing clocking on your network?
The switch operates only as an SNTP client, and cannot provide time services to other systems. So, you can configure it time manually by going:
System > System Management > Time > System Time;
To avoid any issues on your network. I would suggest to use one common SNTP server for all of your network devices. On the switch you can configure it here:
System > System Management > Time > SNTP Settings. If you do not have SNTP server on your network, you can use publicly available one.
Let me know if that helped.
Sincerely,

How to configure netboot across vlans/DHCP when already a windows bootp server in the mix?

Hi All,
We just moved to multiple VLAN's for our Mac's in a mostly WIndows environment. DHCP option 66 points to a Windows Deployment Server & option 67 to the WDS file.
I've tried "sudo bless –netboot –server bsdp://10.2.0.1" on a client but get "Netboot scheme bspd not supported on EFI systems".
I can get changes to the DHCP scopes if needed -except for the boot server, so I was thinking using something like using DHCP Vendor Class Identifier to specify a different bootp server but have no clues how...
Any ideas?
Cheers
Steve

Bonjour across VLANS

I have a segmented network with Multiple VLANs. I would like to configure the network in such a way as to have the Macbooks on VLAN 1 autodiscover services on the Macbooks, airports, and timecapsules on VLAN 2.
So I found the www.dns-sd.org site, and I added the following to our dns zone:
; Add PTR records telling clients that they can browse and register here
b.dns-sd.udp IN PTR @
lb.dns-sd.udp IN PTR @
r.dns-sd.udp IN PTR @
I then set each client to have the correct search domain.
With these in place, I still can not get the Bonjour devices to scan each other across the VLANS.
This is not an IP issue, since I can still manually add the hosts, but I need assistance with the autodiscover features. Any suggestions?

You are asking the wrong question. Bonjour is how iTunes advertises it availability (daap.tcp) on the local LAN. However, even if you managed to see those advertisement on a remote LAN, iTunes also is programmed NOT to service any requests originating from outside of it local LAN (otherwise people could share their music across the Internet.)

RV320 Bonjour Discovery across VLANs?

Hi
I have a network consisting of 2 VLANs - one for the "main" network and one for a "guest" network setup using an RV320 router. I have a couple of Apple TVs and a Sony smart TV setup on the main network VLAN. I would like these devices to be discoverable and usable on the guest VLAN as well. After reading various articles about Bonjour, it seems that this is not easily done.
Can anyone confirm whether or not it is possible to provide this functionality on the RV320 router? Any advice would be most appreciated.
Regards.

Hi Richard,
My name is Andrew and I am a content developer for the Cisco knowledge base.
There is bonjour discovery on the RV320. According to the admin guide, page 61, under the System Management tab. " When this feature is enabled, the device
periodically multicasts Bonjour service records to the LAN to advertise its
existence." According to the photo I provided, it does allow you to enable bonjour on different VLANs.
From there, you can enable or disable bonjour for specific VLANs.
It seems like your configuration would be similar to this topology below,
Where the RV320 can route traffic across different VLANs (with bonjour enabled). You might want to check your Port Management tab if inter-vlan routing is enabled.
I hope this answers your question.

Dhcp offers leaking across vlans

I have a 2960 poe switch connecting a number of voip phones and an Egdemark voip router on access ports on a dedicated voice vlan. It also connects several trunked access points. The 2960 is trunked to an upstream 3560 that provides ip routing for data vlans.
The Edgemark acts as dhcp server for the voip phones. I'm seeing bootps broadcasts from the Edgemark leak onto the data vlans.
Why is this happening? I fixed this by applying on the 3560 an inbound acl denying bootps originating from 2960.
Appreciate any insight

Hi there,
I´m not sure what the Edgemark voip router does, please attach a link or something so I can have a look :-)
In short
Your 3560 will probably have the vlan and ip configuration. Have you specified "ip helper address" that directs dhcp requests to the edgemark?
The requests are not bound to any vlan and can traverse many networks to get to the destination and back. Depending on you size and design of the nework, the requests can take odd paths to reach the dhcp. Anyway, if you specify the helper address the router will send the request the best way to reach the dhcp. At least, they should not "leak" to any other network that is not specified in the helper address command
If the edgemark is placed locally on the same vlan it will catch the requests anyway so you do not have to do this if the phones are just local as well.
Not sure if that answered your question, but that´s how it works.

Mapping across VLANs

We had part of one building burn early Tuesday morning. We are relocating the departments that were affected. 3 people need to be able to map to a particular server on vlan 10. Currently they can map to another server on vlan 10, but not this one. Does anyone have any suggestions as to what could be wrong? Any help would be appreciated. Laruie Coles

Hello CHJamey,
I just saw your post and I'd like to try to help.
As long as all the VLAN's are known objects in the vSphere, the VIN shouldn't have any issues with mapping out which VMs are communicating with other VMs.
You mentioned applications, could you perhaps be a little more specific? Did you mean Automatic Applications, Manual Applications, or the applications running inside the VMs?

Can viruses cut across VLANs?

I have one VLAN with email-enabled workstations and one VLAN with non-email workstation running on the same physical network. The VLANs can't see each other. So can a virus still cross over VLANs? Thanks in advance

hi
a virus can spread itself to other computers using a network communication, such as a tcp session between two computers, in your case the VLANs can t see each other it s okay but it still can communicate with each other using a layer 3 device if configured to do so.
so if two computers from two differents vlan in your network communicate with each other using a L3 device so there is a communication and the virus can cross from one computer in vlan x to another computer in vlan y, if the virus is designed to do so.
HTH
do rate if it does help

RV220W Printer Sharing Across VLANs

We have 2 VLANs configured to keep 2 groups of PCs apart. Is it possible to allow both VLANs to access the same printer without allowing other traffic between these VLANs ?
Any advice would be much appreciated.
Sent from Cisco Technical Support iPhone App

Thanks for the reply Simon.
Should I place the printer in a third VLAN (as opposed to one of the exclusive VLANs containing the PCs)? If so, will it be enough to enable"Inter VLAN Routing" on this third 3rd VLAN only?

Dhcp across vlans

How would I get my dhcp server to assign ip's accross multiple vlans ?

Hi Carl,
We have a feature called 'ip helper', where a layer 3 interface will take a UDP broadcast such as a DHCP discover and forward it to a specified unicast address, such as a DHCP server.
the command is documented here:
