UDP broadcast over multinetted VLAN

We're having an issue with UDP broadcast over a VLAN that has three IP's configured on it. This is on a Cat 6509.
interface Vlan11
description ZZZZ
ip address 10.10.249.1 255.255.255.0 secondary
ip address 10.10.250.1 255.255.255.0 secondary
ip address 192.168.101.1 255.255.255.0
no ip redirects
ip pim sparse-mode
The device broadcasting is 192.168.101.34.
We've added the global config:
ip forward-protocol udp 4444
And we've tried interface commands like:
ip helper-address 192.168.101.34
and
ip directed broadcast
Nothing seems to help, though. Are there any inherit limitations due to the multinet? Devices on the 192.168.101.0/24 subnet receive the broadcast fine. Devices on the other two subnets do not. Basic routing between all subnets is fine.
Thanks,
Joe

Hi John,
If you're running 2008R2 DHCP, you can fix the DHCP issue that you're having by configuring a DHCP super scope on the DHCP server. We ran into that problem too and managed to get DHCP working on all three subnets. I know it works on 2008R2 but not sure on other versions.
We're mandated to get off the 192.168.101.0 subnet; so, if we can't get it working this way we may need to do a complete cutover including re-IP-ing all devices involved in this dilemma. It's more complicated than I'm stating as this is basically a troubleshooting step to see why it broke. There's an application server involved, an audio streaming server, and some Barix devices. We're attempting to get all the workstations cutover first when we ran into this issue.
Thank you,
Joe

UDP BROADCAST

Hello,
is there any way to send one byte on udp broadcast
(255.255.255.255) port 8999 and listen the response with
actionscript.
Thanks a lot

You would need to either enable multicast-unicast on the WLC or the more preferred method would be to enable multicast-multicast on the WLC under CONTROLLER>General. Unicast is a lot of overhead on the WLC as the WLC has to replicate the packet for every AP that is joined to it. With multicast, you have to multicast routing on the network and PIM enabled on the WLC management interface VLAN, the AP VLAN(s), and the client VLAN(s).
Thanks,
Lee

Unable to receive UDP broadcast packets on PPP connection

I am struggling for two days now with no success. I have two modems (do not ask, some special stuff), that uses dial up (PPP) connection. I tried this on windows XP and it works like a charm. I am sending unicast and broadcast UPD packets. If I
repeat that on Windows 7 i can send only unicast data, broadcast packets seems to be lost somewhere. I tried to use Microsoft Network Monitor and I can see that broadcasted packets are being received on my PPP connection. But after that, they are gone. Somewhere
in the kernel. I truly do not understand why. I disabled firewall, antivirus, base filtering engine, tried to log dropped packed in Windows
Filtering Platform, tried clean WIN7 machine and all that with no success.
Here is a sample packet received on interface, but it has newer reach my app:

Hi,
From your description, you may gather the network monitor traces to ensure which part lost UDP broadcast packets.
Thank you.

Why WRT54G ver 7 blocks all UDP broadcasts?

My WRT54G seems to be blocking all UDP broadcasts in the intranet side. Is there an option somewhere, which controls this behaviour, because I have not found one.
It does not matter, if I connect my laptop with a cable or by WLAN, no UDP broadcast packets from my server to the laptop go through.
If I connect to either one of my regular switches, UDP broadcast works perfectly.
Note that I'm not using the WAN port at all, so I would expect no filtering on the traffic.

Interesting!
For sake of argument, can you try using the broadcast address of 255.255.255.255 - this is a limited (local network only) broadcast.
Can you see the MAC (layer 2/ethernet) portion with your tool?
The MAC of the destination needs to be all FFs (all ones) for broadcasts.
I am wondering if something is happening at a lower level - like in how switching is implemented in the linksys. I wonder if a linksys switch (only) also does this.
NOTE - ICMP echo (PINGS) do go through my WRV54G to specific addresses and broacdcast the x.x.x.255 addresses.

UDP Broadcast Traffic from Cisco ASA

Hi,
I want to know that, like Cisco IOS Router, Does Cisco ASA pass the UDP Broadcast traffic e.g., TFTP etc...?
Any thoughts ???
BR,
Mubasher Sultan

Hi Mubasher,
Unlike the router the ASA does not forward any kind of broadcast packet (with the exemption of the DHCP broadcasts when DHCP Relay is enabled).
I understand that your DHCP server is providing here the IP address for your TFTP servers. I guess you are using DHCP option 150.
So if the DHCP server is on one interface and the client is on another you can configure DHCP Relay on your ASA.
http://www.cisco.com/en/US/products/ps6120/products_configuration_example09186a008075fcfb.shtml
In regards of the TFTP requests these will be normal unicast packets as Cadet said so just make sure that you have the proper ACLs and NAT rules for that.

EEM send UDP broadcast

I need an "action" statement that will send a UDP broadcast to port 1001 with a message of "restart". I have the rest of the EEM script created fine. I cannot seem to figure out how to do this. I have a BGP route that changes every once in a while and when it does the application seems to stop functioning correctly. A restart of the application fixes the issue. The vendor says that if I can send the UDP broadcast then he can program it to see the broadcast and restart iteself. I have created an EEM script that sees the syslog "%BGP-5-ADJCHANGE:" and currently sends an email. BUt we have to manually restart the app. If this is not possible within EEM could it be done with a TCL script and the EEM call the TCL script?
I appreciate any words of wisdom. Thank you in advance.

EEM currently does not support UDP. Yes, a tclsh called from EEM could do this assuming you have a new enough IOS. The UDP extension is documented at
http://www.cisco.com/en/US/docs/ios-xml/ios/ios_tcl/configuration/12-4t/nm-script-tcl.html .

Broadcasting over 79xx VoIP speakerphones

Does anyone know if Call Manager has a function where you can broadcast over the speakerphones in an emergency situation? If not, are there products that can do this? Ideally, I'd like something where I can create groups and broadcast to specific groups or to the entire campus.

Hi Brian,
This feature (Group Paging) is not built-in to any CUCM version (including 7.x, unlike CME) but is most possible (via IP Phone speaker and Overhead) using these highly rated Third party products;

Broadcast over lan

Hi,
I was wondering how to write an application that does a broadcasts over a local network.
The idea is one program that does a broadcast over a lan, and the clients respond to that broadcast. Only things I find are MulticastSocket's and similar, but no real broadcast examples.
Any suggestions?

The only difference between multicast and broadcast packets are the network you use. A multicast is in the 224+.*.*.* range and a broadcast is typically limited to the network the server is on e.g. 10.10.10.*

Using UDP broadcast instead of UDP multicast on a LAN (multicast not working on a major UK ISP router)

I've built an Android app using Cirrus that allows users on a LAN to chat in Morse code! - You can find it on the Android Market by searching for 'Morse Intercom'.
It works fine on my network, lots of other networks, but not on probably the most popular fast broadband fibre network in the UK
A friend of mine has let me piggyback on her network from this provider, and the problem appears to be that the UDP multicast packets RTMFP transmits just aren't being put on the wireless network. FYI the multicast address I use is IP 225.226.227.1 port 32112 .
This is probably fixable in the router, but 99.5% of users will never mess around with the router (and why should they), and if possible I would like to fix this in RTMFP.
Is it possible for me to ask RTMFP to not use UDP multicast, but instead to use UDB broadcast for discovering peers on the LAN ? The problematical router (and all others?) supports UDP broadcasting.
I tried setting 'groupspec.ipMulticastMemberUpdatesEnabled = false;' but this just stopped the app working on anything! What is the purpose of this option?
FYI:
To connect without using Cirrus server assistance I use: nc.connect("rtmfp:");
The complete function I use for setting up multicasting is:
private function setupGroup():void
// Create a new Group Specifier object
//trace("setUpGroup: groupSpec = new GroupSpecifier('myGroup/groupA')");
trace("setUpGroup: groupSpec = new GroupSpecifier('" + MY_UNIQUE_GROUP_NAME + "')");
var groupspec:GroupSpecifier = new GroupSpecifier(MY_UNIQUE_GROUP_NAME);
// Enable posting
trace("setUpGroup: groupspec.postingEnabled = true");
groupspec.postingEnabled = true;
// Specifies whether information about group membership can be exchanged on IP multicast sockets
trace("setUpGroup: groupspec.ipMulticastMemberUpdatesEnabled = true");
groupspec.ipMulticastMemberUpdatesEnabled = true;
// Causes the associated NetStream or NetGroup to join the specified IP multicast group and listen to the specified UDP port.
//trace("setUpGroup: groupspec.addIPMulticastAddress('225.225.0.1:30000')");
trace("setUpGroup: groupspec.addIPMulticastAddress('" + MY_MULTICAST_ADDRESS + "')");
groupspec.addIPMulticastAddress(MY_MULTICAST_ADDRESS);
// Constructs a NetGroup on the specified NetConnection object and joins it to the group specified by groupspec.
trace("setUpGroup: group = new NetGroup(nc,groupspec.groupspecWithAuthorizations())");
group = new NetGroup(nc,groupspec.groupspecWithAuthorizations());
// Set the NET_STATUS event listener
trace("setUpGroup: group.addEventListener(NetStatusEvent.NET_STATUS,netStatus)");
group.addEventListener(NetStatusEvent.NET_STATUS,netStatus);
In conclusion - On a LAN with up to 250 or so hosts, I can't see why RTMFP shouldn't be able to use UDP broadcasting as an alternative to UDP Multicasting. Can it, and if so how?
Graham

Here's more information...
When trying to connect with a 3rd party product, the connection request is sent out to my ISP's DNS server with details of the service ID. Of course it won't find anything there.
So then is tries to use NBNS (Netbios Naming Service) on 192.168.1.255, and still can't connect. Then comes back with a TNS error. i tried TNSPING on this address, and it doesn't find it. I have no clue where it gets this address from.
WHY WON'T IT JUST CONNECT TO THE HOST MACHINE AS DEFINED IN THE TNSNAMES FILE???
PLEASE HELP!!!!

Will ESPN continue to be broadcast over the aerial...

My biggest gripe with ESPN at the moment is that it cuts off at 4am, which is a big deal if you're into American sports. Broadcasts over the aerial will always be preferable to Internet streaming for me.
Thanks.

I have my card for the Vision+ box, 58 is showing BT Sport 1 in the corner and 59 shows BT Sport 2, 57 now shows no on screen DOG, however all 3 channels are showing the same promo, but flicking between the 3, they are all at different stages, so 57 isn't a "copy" broadcast of 58 or 59.
On another forum, someone got a bit technical, but the basic was the bitrate that each channel was using and that all 3 were separate channels/labels.
So what is 57 for, come the 1st August?
Has BT leased it, like the BBC for 302 and 303 and it is only short term to "sell" the BT Sport service with 57 to disappear sooner rather than later?
Perhaps, 57 will become ESPN, since everyone was surprised that BT Sport didn't appear on the same channel numbers that BT used for Sky Sports, due to the when the sale of the channel becomes official plus the fact that ESPN is currently broadcasting on another DTT number, maybe there is a legal reason that 57 can't be labelled or announced till the end of the month?
BT up to now, haven't been the most forthcoming with information, i had one call to them, that the answer was, "we don't know when the cards get sent out", needless to say my card arrived, i notice the TV promo states the £10 activation for the card, yet i got an email and a letter with the card stating it was free.
Maybe i'm reading too much into this, yet 3 channels have appeared on DTT, all broadcasting what would seem to be 3 separate streams, so unless one of them is a short term lease, what else can 57 be for?
BT have been coy about the various ways that BT Sport/ESPN is getting delivered, with things changing all the time, so who knows, only way to find out is wait till the 1st August and see what 57 is showing.

Aironet 1252 doesn't broadcast SSID and VLANs

Best regards.
I have an autonomus AP Aironet 1252 (software version: 12.4(18a)JA1)
I configured 3 SSID and VLANs, but the AP doesn't broadcast SSID, the vlans are working fine because I tested configuring manually the hide SSID on laptops.
Also the AP broadcasts the SSID whe only one SSID is configured!!!
How I can do the AP to broadcast all SSIDs?
Thanks in advance.

From the command line of your AP.
Change each SSID as follows. You want to turn off "guest-mode" and enable "mbssid" at each SSID. Guest-mode will only broadcast one SSID, you must use mbssid to allow all SSIDs to broadcast.
#config t
#dot11 ssid
#no guest-mode
#mbssid
Now from each radio
#int d0
#mbssid
#int d1
#mbssid

DatagramSocket not picking up UDP broadcasts

Hi All.
Opened a DatagramSocket on specific port. Verfied (w/ tcpdump) that other process is sending UDP packets to that port with broadcast address (128.0.3.255). {pseudocode}DatagramSocket.recieve(dgram) never picks up the packets.
If I change the sender to use specific IP (unicast), the recieve gets the packet and unblocks.
JRE1_5
Any ideas?
-K

Are you binding the socket to the wildcard address?
Is that really your broadcast address? The 128.0.0.0/16 address block is slightly unusual (RFC 3330). broadcast = ip_address | ~netmask; (or use 255.255.255.255).
Try these programs; do they work for you? If they do, what is different between these and your program:
import java.io.*;
import java.net.*;
public class BroadcastSend
    public static void main(String args[])
     throws Exception
     DatagramSocket socket = new DatagramSocket();
     socket.setBroadcast(true);
     socket.setReceiveBufferSize(64 * 1024);
     socket.setSendBufferSize(64 * 1024);
     int str_size = args.length == 0 ? 256 : Integer.parseInt(args[0]);
     StringBuffer str = new StringBuffer();
     while (str.length() < str_size)
         str.append("hello world");
     str.setLength(str_size);
     byte buf[] = str.toString().getBytes("ISO-8859-1");
     InetAddress address = InetAddress.getByName("255.255.255.255");
     DatagramPacket packet = new DatagramPacket(buf, buf.length, address, 6666);
     socket.send(packet);
import java.io.*;
import java.net.*;
public class BroadcastReceive
    public static void main(String args[])
     throws Exception
     DatagramSocket socket = new DatagramSocket(6666);
     socket.setBroadcast(true);
     socket.setReceiveBufferSize(64 * 1024);
     socket.setSendBufferSize(64 * 1024);
     while (true) {
         byte buf[] = new byte[64 * 1024];
         DatagramPacket packet = new DatagramPacket(buf, buf.length);
         socket.receive(packet);
         System.out.println("got " + packet.getLength() +
                      " bytes from " + packet.getAddress());

Live Video Broadcasting over LAN

Hi Guys,
I have studied the JMF Framework.
And sucessfully transmitted and received video and audio over a network i.e. LAN.
Also I have successful in displaying Webcam onto applet.
Only issue with me is how do I broadcast the Live Video to clients.
Do help me at the earliest.
Thanks and Regards,

Ummm, the same way you broadcast a video file.
You feed the DataSource associated with your web cam through a Processor, program the Processor's tracks to output the encoding you want, and then you send that out via RTP.
And on the receiving end, nothing changes from the video file.

Broadcasting over LAN

I am working on a program that broadcasts a packet over the LAN.I implemented a datagram packet which has some data inside .Is there any way to broadcast this message to the computers without specifying the port number..I want all the computers on LAN to take this packet
here is the part of the code.
DatagramSocket socket = new DatagramSocket();
InetAddress address=InetAddress.getByName("255.255.255.255");
DatagramPacket sendPacket =new DatagramPacket(m,m.length,address,?????);
socket.send(sendPacket);

Hi!
as far as i know you have to set a port number ;) so:
int port = 2000;
DatagramSocket socket = new DatagramSocket(port);
hmm... getByName is not a good idea, try getByAddress, defining a byteArray first (255,255,255,255).
InetAddress address=InetAddress.getByAddress(yourByteArray);
Define your sendPacket like thist, where "buf" is the byteArray of your sendData, like:
buf = sendData.getBytes();
DatagramPacket sendPacket =new DatagramPacket(buf, buf.length, address, port);
finally:
socket.send(sendPacket);
could work...
greetings

SUN NIS Broadcast across multiple vlans

We're big sun servers and clients shop. The problem is that NIS is not able to go across multiple vlans on a layer 3 switch. I have enable the forward-udp protcol sunrpc but it still doesn't work. Is anybody else ever run into this issue?

This might help you. Use the Ip-helper adress along with the forward udp command. Look at this link under the IP- helper command. Should answer your question.
