WAN Ethernet - Multicast

Could someone explain how multicast traffic is handled for specific customer in carrier network . The Main office and remote offices are connected via L2 Ethernet service.
The question I have is since WAN ethernet is shared medium once my multicast traffic is get into the carrier network how they handle the multicast traffic.
1.Should all the customers will receive the multicast traffic? OR
2.Somehow the traffic will be routed to my remote offices only by the carrier. How they do ?
3. Do I need to ask carrier any specific questions regarding Multicast when I subscribe WAN Ethernet service.
Thank you,
Raja Ramasamy

Raja, the MVPN concept in L3VPN needs the SP backbone to be multicast enabled in contrast to L2VPN, where the multicst traffic is switched as any other traffic.
For idea behind MVPN in MPLS is to encapsulate VPN multicast packets into a multicast GRE tunnel which connects all the PE's where this VRF termiates. (this is controlled by the Default MDT configuration).
So essentially you build a backbone within a backbone for your end customer.
When the backbone is in place via default MDT, to enhance traffic forwarding to only intrested receivers and not to all end points, data MDT is put in place which forwards traffic between a source and intrested destinations. (this can be configured to trigger when a certain data threshold is crossed using the default MDT path for multicast traffic)
Here is a neat white paper with illustrations for reference.

WAN Ethernet Port Settings?

Under the Apple Airport Admin Utility/Internet tab there is a button marked WAN Ethernet Port. This button gives you several options, including "Automatic", and then four other options referring to what I guess are port speeds, and the terms "Half Duplex" and "Full Duplex". Any one have a clue to what these are/mean? What should I choose to maximize my Base Station?
I'm running a LinkSys Cable Modem into my Base Station. Right now I'm supposed to be getting 8 MBps service thru Comcast. But I'm only maxing out at about 768 kbps.
eMac 1.25 Mac OS X (10.4.6)

Those all have to do with ethernet port speed and transmission of data. Automatic means the ethernet port will try and sense what it is connected to and set the correct port speed and duplexing level. The duplexing means transmission of data. Half duplex will transmit data in just one direction at a time and full means that it will transmit and recieve at the same time. A walkie talkie is an example of half duplex and a telephone is an example of full.
Usally setting it to automatic is the way to go but you want to make sure each side is the same. Make sure whatever your cable modem is set to (Automatic, 100/Full, 100/Half, etc.) is the same on the WAN port of the AE.
If not you will receive CRC errors etc causing slowdowns and retransmission of data.
I hope this helps.

Whats the speed of connecting wan ethernet and coax cable

I have fios internet with phone no tv added and the guy came over and installed cat 6 to the router instead of coax, is the wan ethernet faster for downloads files rather than wan coax??? my plan package is the 15/5 mbps

Actually the MoCA is 1.0, I believe ... so it's probably topping out at 175mbps, but as you said ... both ethernet @ 100mb and MoCa at 175mbs are both an order of magnitude faster than the 15mb downstream rate the OP is provisioned for. So it doesn't matter how they provisioned the connection.

WLC controller Ethernet Multicast Mode

When do you enable the ethernet multicast mode on controller? In my test lab, I have it disabled and I have not seen any issues so far. Thanks.

When you are supporting Wireless Applications that require MC, such as Spectralink's (ca use MC for registration as well as Push-to-Talk).
However, it is a common mistake to use the same MC group that your application uses.... Wrong! The WLC controller actually uses the configured MC group to distribute MC traffic to the joined AP's, so you really want to use a group that is not used by the actual applications.
(don't forget to rate all responses)

Airport Express won't connect to internet via WAN ethernet

I have new model Airport Express (AE)
I am attempting to use the AE as a wifi router in my office. I'm sure the office has some sort of secure internet, although when I hardwire my computer to the internet via ethernet my computer connects immediately to internet with no passwords or logins necessary.
I have set up my AE to create a new wireless network. It is ready to go, but it does not recognize that it is connected to internet. Ethernet cord is plugged into WAN input, and other end is plugged into wall for office supplied internet.
AE will not recognize that it is connected to internet.
I assume this is due to something with the office supplied internet being secured or "special." Is there a work around here, or suggested next steps?
Thanks.

If you get all three together, "Ethernet unplugged" would pretty much explain the other two errors. Troubleshoot that first.
Is the same ethernet cable you are using with the AE the same one that worked with your computer? Is it oriented in the same direction (same end to the wall) as when it was used with the computer? Your office might use a non-standard cabling system or be taking some other measures to deter the use of foreign equipment.
Have you asked your office's technical support folks for any special instructions?

Ethernet multicasting without IP

Does somebody have experience with switching pure multicast traffic? (layer 2, with on top a proprietary connectionless layer 3-7 messaging protocol). I have one multicast source, sending m-packets to 27 other stations all listening to the same group address and all are connected to a 2950-switch. Traffic load is minimal (<3%) but 99% is multicast. For an unknown reason, the switch is dropping an awful lot of packets. Many, many thanks for any suggestions.

Try it with a hub (not a switch) for diagnostic purposes.
If you are still seeing lost packets, then it is likely to something the receiver's inability to to queue and process the volume of traffic.
Passing broadcast and multicast traffic is not a big deal for a switch; with no configuration (out-of-the-box) any switch is will pass any (unerrored) broadcast or multicast traffic. The architecture of the switching fabric makes it a trivial task.
That being said, you may want to check out the broadcast supression settings (I don't think it applies, because are using multicast (right?)), but there are thresholds that can be adjusted for the amount of broadcast traffic you consider "normal."
Check out this link, especially the part under "Understanding Storm Control:"
http://www.cisco.com/en/US/products/hw/switches/ps628/products_configuration_guide_chapter09186a0080212a9f.html
The reason I suggested a hub is because hubs are repeaters; they don't "store & forward" ... they don't act on the signal at all .... they just repeat the traffic pulse-for-pulse to all the other ports.
If you use a hub, and the problem remains, it's not an infrastructure problem, it's a transmitter / receiver problem (probably the host side processing ability, hardware or software).

Ethernet multicast per AP?

Using the wcs 4402 controllers. we can enable multicast under the general properties which affects all APs connected to it. Is there a way to have multicast support for just a few APs? We have some mac users that want to run "bonjour" (formerly rendevous) and the app relies on multicast being enabled, however, it puts an extra load on the wireless network

It's my understanding from a class that multicasts in the LWAPP system are handled externally to the LWAPP tunnel (i.e., through the routers as "plain old" multicasts.
It's that recollection is correct, then you can control the multicasts only to those zones that you want to propagate them using PIM.
True or not, here's a list of links from the main Cisco site with some details about setting up multicast groups on the LWAPP system.
A "group" is a specific multicast address that would limit the multicasts to specific LWAPS / zones.

The two machine are on different networks.
My goal is to have Machine A send multicast data thru eth2 to be sent in the wan and to be received by Machine B on eth2 too.
Obviously the two machine are on separated networks.
I have tried everything I could but I cannot get machine B to pickup the messages sent by A. It worked fine when on the same LAN but not over WAN.
The multicast address that I use it 239.55.55.80 and the port 4445.
I think I have a problem to link the interface to my app ( I used setInterface and setNetworkinterface but nithing.) Also I cannot firgure out if the things that I am doing wrong are on the server or the client.
Here is the code for the sever and client.

never Mind I found the issue
The default value for TTL is 1.
I was going thru multiple routers so I incremented the value and it worked

Share USB Disks over Ethernet WAN port

What exactly does this option enable? The manual is a little less than clear. If I enable it, how would I access the drive remotely? I have dyndns set up, and the AEBS get's the Internet routable IP.
But what method would I use? HTTP? FTP? What?
I saw one post where it made it sound like this would actually keep dyndns updated with any IP changes, but that seems unlikely with how it is worded and documented.
thanks,
Sean

According to a couple of reviews, sharing over wan is CIFS for Windows and AFP for Mac. I can access the drive remotely using AFP, but not CIFS. I go into "map network drive" and enter the server as follows:
\\domain.dyndns.org\hdname
That works when the machine is on the local network, but if I turn on the VPN, which makes it look like the machine is remote, it fails.
I have the drive shared via wan ethernet enabled, and bonjour turned on.
any ideas?
Thanks,
Sean

Srp521w ethernet sub interfaces on WAN

Hi there,
Have followed the admin guide, and can setup this up fine, however what we're wanting is to turn off any IP connection for the main wan ethernet interface and only have the sub-interface have an IP connection method.
I can't see how you can turn this off, which is causing a double-up of dhcp requests being sent when using both the main/sub ethernet interfaces to use dhcp.
This has been tested on the 521w and 521w-u versions, and I've just used the latest firmware 1.2.4 on the u version.
How can this be configured so that there is only 1 WAN interface that is using IP (the sub interface)
Setting default routes to point to the sub interface doesn't make a difference.
Thanks in advance.
Chaz

Hi Chaz,
Configuring a static IP address on the main interface would be the only way to make it passive. The address to use here could be the same for all routers, as technically it will never be used.
Ensure that you set the interface default route for the WAN interface to the new sub interface.
See the following as an example (I use private 192.168.. addressing in my lab.)
Cheers
Andy

SRP547W, How to use multiple WAN IPs for port forwarding?

Hi folks,
We've run into some difficulty trying to take advantage of multiple WAN IPs in conjunction with the SRP547, and I'm hoping someone here can help out or at least tell us that we're going to need to buy a different router...
What we're trying to acheive is the ability to port forward from our distinct public IPs to different internal servers. Looking at the options under Port Forwarding it looks like we can only configure forwards at the "WAN interface" level, but our problem is that we can't work out how to set up separate interfaces for each of our Public IPs...
Our ISP provides us with a fully managed NTU/router with a single "Internet" ethernet port, which we can use by statically configuring IPs on our end. For this configuration this port has been directly patched to the WAN ethernet port on the SRP547W.
We have been allocated a 255.255.255.248 (/29) subnet, giving us 5 usable IPs after the ISP's gateway address is taken into account, like so:
a.b.c.208     Network Address (/29 subnet)
a.b.c.209     ISP Gateway
a.b.c.210     IP1
a.b.c.211     IP2
a.b.c.212     IP3
a.b.c.213     IP4
a.b.c.214     IP5
a.b.c.215     Broadcast Address
On the SRP we've set up the default "Ethernet WAN2" sub-interface with the following details for IP1
VLAN ID:               4088 (Uneditable)
Connection Type:       Static IP
Internet IP Address:   a.b.c.210
Subnet Mask:           255.255.255.248
Default Gateway:       a.b.c.209
The next step (I would have thought) would be to add a second sub-interface, using similar info for IP2
VLAN ID:               4000 (Chosen arbitrarily)
Connection Type:       Static IP
Internet IP Address:   a.b.c.211
Subnet Mask:           255.255.255.248
Default Gateway:       a.b.c.209
When we try to do so however we get:
Fail!
Conflict with Ether_WAN2 interface address type
I should mention at this point that we're running on firmware version 1.02.01 (023).
Any suggestions on how we can proceed?
Is there a CLI or other method of configuration that might work if the web interface won't?
Thanks,
Tim.

OK, I've seen reference to this solution before but not much in the way of details. Perhaps you can spell out how this ought to work, as the Software DMZ doesn't behave as I'd expected it to.
As before, on the SRP we've set up the default "Ethernet WAN2" sub-interface with the details for IP1 with a /29 subnet.
VLAN ID:               4088 (Uneditable)
Connection Type:       Static IP
Internet IP Address:   a.b.c.210
Subnet Mask:           255.255.255.248
Default Gateway:       a.b.c.209
We'd now like to expose a server function on IP2, let's say LAN details for this server are:
VLAN:                  3000
VLAN IP Range:         192.168.1.1/24
Server IP:             192.168.1.10
Server Port:           80
So first we turn on Software DMZ:
Status:                Enabled
Public IP:             a.b.c.211
Private IP:            192.168.1.10
WAN Interface:         Ether_WAN2
My understanding, based on what you've said, is that this should expose the whole server to external access via IP2. Unfortunately, it doesn't seem to work this way - we don't seem to have any access at all. Perhaps there's a default deny rule on the firewall?
Just to be sure, I tried creating a rule to allow HTTP traffic to the server in the Advanced Firewall page.
In Interface (WAN):    All
Out Interface (LAN):   VLAN.3000
Source IP:             0.0.0.0
Source Subnet:         0.0.0.0
Destination IP:        192.168.1.10
Destination Subnet:    255.255.255.255
Protocol:              TCP
Source Port:           Any
Destination Port:      Single:80
Action:                Permit
Schedule:              Everyday
Times:                 24 Hours
Still no dice. What am I missing?
Cheers,
Tim.

WLC - AP Groups - Multicast - Bonjour - Apple TVv3

Good Morning
first off - Should start off by saying I have followed the Apple Bonjour deployment guide [except for interface group] portion
I have searched high and low, here and there to no avail.
http://www.cisco.com/en/US/products/hw/wireless/ps4570/products_tech_note09186a0080bb1d7c.shtml
I am aware that the bonjour gateway IOS may or may not come out in Oct/Nov 2012, which maybe my only option at this point.
Is this not working because of my AP groups setup or have I misssed something
I can only get bonjour to work if multicast - unicast mode is selected, but our network slowly grinds to a halt, so it is not an option
when I first connect to the wireless I see 1 bonjour device for about 3 minutes and then disappears.
I can not see the appletv at all with an ipad, airplay does not appear at all.
We have the following setup.
2 campuses - Campus 2 is simular setup, but WLCs higher model and ios 7.2 and clients and subnets are double
Campus 1
2 WLC 4404 ios 7.0.230.0
30 AP groups mapped to 30 Interfaces using subnets with /23 bit subnetmasks
multicast - multicast is set with multicast addresses of
controller 1 239.239.5.1 and
controller 2 239.239.5.2
multicast is enabled
IGMPsnooping as well
On Switch multicast routing is enabled
all AP group subnets and Mgmt vlans are PIM enabled dense mode
set up a trunk to ubuntu server to act as a bonjour gateway, installed avahi and vlan

Should Bonjour work same subnet with these settings?
I am going to have read more about the Interface groups and the Multicast vlan.

10.5.6 setup on mini with USB nic, not receiving DHCP from WAN (cable modem

Hello,
I'm probably in a little over my head thinking I could configure MacOS X Server without much IT knowledge. But I started, so I'm not giving up yet.
Here's my setup:
— cable modem ethernet connects to USB nic (the apple macbook air one) plugged into mac mini running 10.5.6 Server
— ethernet on mac mini connects to switch
— switch connects to airport base station set-up as bridge
— in the future other computers will connect over ethernet to the switch (that's why mac mini isn't plugged into base station directly)
Here's the issue:
— cable modem uses DHCP (no fixed IP).
— when first installing 10.5.6 Server, modem was connected directly to ethernet on mac mini, and picked up everything from DHCP, worked fine. Ran all the system updates (started with a 10.5 initial install)
— after everything was installed, I switched the modem to the USB ethernet adapter and ran NAT setup assistant. configured the USB Ethernet as the WAN, Ethernet as the LAN, turned on VPN.
— now the USB Ethernet won't pick up the DHCP of the WAN anymore. It did it once, and then never again.
— I've run the NAT setup assistant to switch the WAN and LAN nics to see if the USB Ethernet was the issue, but with the same results.
— This setup used to work although not quite stable on 10.5.4 server.
My initial questions:
— is the firewall blocking the DHCP?
— is the LAN DHCP messing with the WAN?
— in the previous version I had to set the replythresholdseconds from 10 to 0 in the bootpd.plist for it to hand out DHCP on the LAN, but there is no such entry in the pootpd.plist anylonger, and the keynet_address entry that was missing from the previous version of bootpd.plist is now present, so it seems the bootpd.plist has been fixed by apple.
— what am I doing wrong? Why doesn't this just work as advertised...
I know there are several of you out there that have the same setup working (I found posts from hirstey and DigiAngel with the same setup) so it must be possible. All your help is much appreciated!!
Thanks,
Hagenaer

Thanks for your reply, DigiAngel.
DSL modems differ from cable modems as far as I understand. Where DSL modems are actually routers capable of NAT/DHCP, cable modems are just a network interface/brigde and can't do any of that. So it should pass the external IP to the computer. I'm writing on a laptop with the cable modem directly plugged into it, and it picked up the external IP etc. near instantly. The mac mini did the same before I ran the NAT setup assistant. I believe it picked it up once after that, but never since.
I had done a clean install, had the ethernet plugged into its internal ethernet port (en0) and was able to download all the system updates. Then plugged in the USB ethernet, I'm pretty sure it still picked up the IP there. Ran the NAT setup assistant and can't get anything to work anymore. Even with all services switched off.
So the modem is doing its job, but when I connect it to the USB nic the connection gets a self-assigned IP in about 3 seconds after seeing the cable is connected. The one time I've seen it get the right IP, it got a self-assigned IP first and then about 5 seconds later picked up on the correct IP. (And it picked up everything, including DNS server and search domains, which this laptop I'm writing on does not, although it works just the same).
Unfortunately, this laptop runs 10.4.11 which doesn't recognize the USB nic, so I can't test the adapter outside of the server environment. But I've had the genius bar test the adapter previously and it worked fine then, plus I've run the NAT setup assistant with the connections inverted (WAN over built-in ethernet, LAN over USB ethernet) with the same results: WAN gets self-assigned IP.
I've also tried configuring manual IP for the WAN from what I saw was given to this laptop (it kept the same IP even after being disconnected/reconnected, so I guess the IP for my modem won't change IP unless I reset it. Although I'm not sure if it's correct logic to assume the mac mini would pick up the same IP as well since I think that's actually tied to the MAC address and the IP doesn't belong to the modem but to the computer behind it).
Anyway, I'm not sure what to try next...
Hm. Wait, this might have something to do with it: the firewall logs the following:
Mar 22 14:12:07 server ipfw[4997]: 65534 Deny UDP 73.227.220.1:67 255.255.255.255:68 in via en 2
Looking up 73.227.220.1 gives me dns1.inflow.pa.bo.comcast.net, clearly my provider's DNS server. Trying to get me an IP that my wirewall is denying? Turning off the firewall doesn't make it pick up the correct IP though... I have turned off all services and still just got a self-assigned IP.

Ethernet port on QIP7100 2

There's an Ethernet port on the QIP7100 2 STB (the manual states that it's 10/100). Does it have any use? Specifically, can it be used instead of the coax connection?
Thanks,
Willie
Solved!
Go to Solution.

Its there because Motorola markets to other than Verizon. But Verizon does not use it or activate it. Must be COAX and MOCA internet connection.
The same does not apply to the routers, most/all of which have a wan Ethernet and 4 regular Ethernet connections. The 4 regular Ethernet connection can be used. The wan connection can be connected by Ethernet to the ONT and used, but that does require you to call and ask for it to be activated. Note that those with FIOS speeds above 100 are connected that way. If using the wan Ethernet and you have FIOS TV both coax and wan connection remain connected to the ONT.

Wan port question

Could someone explain to me the Ethernet wan port menu. I'm having a lot of connection problems with Airplay. It keeps dropping and coming back on.
I checked with my ISP and the signal (cable) is 100% stable so the problem has to be my AE.
If I change the settings to 10Mbps/half Duplex, it seems to work ok for a while. But Automatic is a definite no-no.
Why all those choices, especially half and full duplex and what do they mean in terms of overall performance ?
Thx

My question to you is did this always happen or just started happening with this modem & AirPort base station. What is the exact model of your AirPort? How about the modem?
This has always happened since installation 3 months ago
AE 1143 - Modem is : Motorola SB5101
Is 8 Mbps the maximum rated download speed that your ISP is providing you for Internet service?
Yes
Is 8 Mbps the maximum rated download speed that your ISP is providing you for Internet service?
Speed test (http://www.speedtest.net/)
up: 8.17 - down: 1.02
Changing the WAN Ethernet port speed will do nothing to improve AirPlay's performance.
But it does ! With lower speed = less drop in feed. Or maybe it's just the fact that I change from one to another.
