Cisco Wireless :: To Verify Multicast With WLC 5508
Dec 25, 2012
I used the wlc 5508 GUI to enable multicast in the CONTROLLER section, AP Multicast mode "Multicast" with a group address 239.1.1.1. Also in the "Multicast" section enabled Global Multicast Mode and IGMP Snooping.
My wired network is using a bsr and pim sparse-mode all around. My wlc is connected to a core 6513 L3 switch and on a neighbor L3 switch I can see a shared tree mroute entry and a source based entry for the wlc multicast group I created,
sh ip mroute
( *, 239.1.1.1 )
( 192.168.0.1, 239.1.1.1 )
I can't ping 239.1.1.1 though from anywhere, even the wlc's gui using the ping tool.I can do an ip igmp join on a loopback and ping from a neighbor device and get a reply.
In the monitor multicast section of the gui I can see some Layer2 MGID entries and one in the Layer3 MGID section but not for the 239.1.1.1 address.How do I verify my multicast over wireless setup is working correctly?

I am using WLC 5508 version 7.0 facing issue while enabling global multicast mode .
client machine stops DNS resolution after some time once we enable global multicast mode on WLC .websites are opening with IPs but not with DNS names .
DNS resolution starts working immediately after disabling multicast mode on wlc .

I'm starting to see an error creep up that I havn't seen since 2003/2004 on my brand new 5508 controllers. I'm recieving the following from my WCS: Receive Multicast Queue is full on Controller and then on the controller itself RX Multicast Queue Full. I understand this used to be due to a large influx of ARP requests or CDP packets on older controllers but, this was supposed to be fixed in an update many years ago.
Has seen this on their 5508's. These were advertised as having the horsepower to handle our user loads which arn't really that high at 300 users at any given time max.

I try to pass multicast traffic between two vrf on the same 3750 switch. I have IP services IOS and sdm template routing.
here is my config:
ip routing
!
ip vrf vpn2
rd 1:1
mdt default 232.1.1.1
route-target export 1:1
route-target import 1:1
[code]....
Now I'm stuck - I don't know what to do to pass multicast traffic. Do I have any chance to run this config on 3750 chassis?Perhaps "Configuring Multicast VPN Extranet Support" document will be useful, but it concerns Catalyst 6500? [URL]

I'm working on setting up a site-to-site VPN connection that requires us to NAT an internal address. Typically, this would be no big deal, but for some reason, it's not working for us. The remote site is reporting that they are seeing the original IP address and not the mapped address coming across. I've monitored the connection and base on our ASA logs, I too see the un-mapped address.
Is there a quick and easy way of verifying that NAT is working? Logs, etc.?
Unfortunately I don't currently have the remote side's configuration, as they are an external business, but I can provide ours: [code]
Based on the above, it sounds as if our configs aren't jibing, which I would think could be caused by the NAT configuration not working, right? I mean if the VPN applicance on the remote end is expecting a NAT-ed address of 12.131.67.247 and they are receiving 12.10.127.108, that could cause this issue, couldn't it?

Getting this error on the data center 2581 (12.4(24)T) from a GRE/IPSEC tunnel, remote branch is 2811 running 12.4(25d)
%CRYPTO-4-RECVD_PKT_MAC_ERR: decrypt: mac verify failed for connection id=
The tunnel has been up and working okay for months, nothing has changed on the config and the key is correct. Traffic is following but remote users are complaining of performance issues. A wireshark shows checksum errors and lots of packet resends. Remote ISP has checked the circuit and says its clean.The data centre router has quite a few tunnels but only 1 causing this issue. From the head end router -
sh crypto ips sa | b x.x.x.x
current_peer x.x.x.xport 500 PERMIT, flags={origin_is_acl,} #pkts encaps: 15129, #pkts encrypt: 15129, #pkts digest: 15129 #pkts decaps: 13346, #pkts decrypt: 13346, #pkts verify: 13346 #pkts compressed: 0, #pkts decompressed: 0 #pkts not compressed: 0, #pkts compr. failed: 0 #pkts not decompressed: 0, #pkts decompress failed: 0 #send errors 1, #recv errors 1992
Can a VPN module go bad like this? I've tried disabling the branch onboard engine and using software but it doesn't work.

I have disabled Unicast RPF on a Cisco ASA 5510 for one specific interface. However, how do I verify that RPF indeed has been disabled on that particular interface? It doesn't show up in the config, neither does it up when I issue the command "sh int interface'.
To disable the RPF feature, I issued the following command: no ip verify reverse-path interface interface_name

someone at work sent me an e-mail they claim was forwarded. I don't think it was, and I need to know before I ask, because accusing someone of making it look forwarded, I viewed the source code, but I can't tell, it was sent through a microsoft exchange server.I think they copied and pasted and changed dates, is there anyway to tell from the source code?

The network gods recently updated our 6500 and upon reboot, the FWSM booted to CF:1 maintence partition,which caused an immediate outage. On the router, I ran the following command to set the default FWSM boot partition to the configuration with:Router#boot device module 4 cf:5 However, it appears the "show boot device" command has been replaced with "show bootvar" which doesn't show me which partition the router will boot the FWSM to. Is there a command I can run from the Router that will actually confirm the boot partition for the FWSM if the router reloads.

The story is that we recently upgraded our 4404 controller to the new 7.2.0.230 code. This upgrade was from 4.2.209 code. I would like to make the change to the Multicast setup so that It is multcasted and not unicasted.So I went into the controller and selected MULTICAST for AP multicast mode and entered in a multicast ip of 239.255.1.60 ( default choosen in the cisco howto's)I then test the reason for enabling the multicast and it doesnt work. The problem is that the Wireless HP printers setup to use Apples IPRINT are not able to be found. However, when I select the Multicast setting for the APs to be UNICAST the Ipads can find the Printers and print to them.What am I doing wrong with this Multicast setting? Do i need to add a Multicast address to the router?

Do I need to but something in there?

We are experiencing some issues with the Apple TV and WLC. We currently have a Apple TV and iPhone same sub net connecting via Lightweight AP (different sub net) which connects to a Cisco3750 running IP Base. This connects to WAN routers managed by third party over a WAN and connects to far end Managed routers, these connect to other Cisco3750 IP Base and onto a 2504 Wireless LAN controller. We have used the the following document for WLC configuration; [URL]
We turn on Multicast globally, with IGMP snooping enabled also enable Multicast Multicast under controller (only option available on 2504) and give the device M Cast address 239.21.1.150 . The P2P blocking action is disabled. Going to Monitor Multicast we can see the Report for 224.0.0.251 and MGID. However the issue is at the Sender Receiver side the iPhone cannot see the Airplay on the iPhone that should be seen if the end to end stream is working. My focus is now on the Cisco3750's, although I do not totally understand why the device needs Multicast enabled as the Multicast Join and Group Traffic is encapsulated in the CAP WAP Tunnel is it not? Anyway I have enabled the only option "ip multicast routing distributed" and under the V LANs that connect to WLC and AP the only option available is the "ip pim passive" there is no "ip pim sparese-dense mode"
I am sure the WLC is configured correctly, but I suspect that this will not work due to the IP Base image on the 3750's not being able to run full multicast or we need to use uni cast for this solution that the 2504 does not support.

We have an ASA with 8.4(5) version. we had detected that few ip's were getting shunned ,to overcome the problem no shun was used and the traffic normalised.But, the same problem re-occured a few days after that with logs showing traffic being shunned.
is there any fixed way to get rid of this. what commands can i use to verify related configuration on the firewall.

I've bought a E3000 as replacement for my Linksys WRT350N router.Just upgraded the firmware to version Ver.1.0. 04 (build 6).I use aonTV - an austria IPTV service (Multicast via UDP) - an this worked with my old WRT350N (hw version 1) consistantly well. I hardly had to reboot the router to get the multicast stream.With E3000 I checked the option that it should not filter any multicast traffic - when I reboot the router it works for some time - but after some hours it does not work anymore? I want to watch TV via my HTPC connected via GigaBit Power to the E3000.

AP radio resets when the AP Multicast Mode IP is set 0.0.0.0 under the General Tab?
I rebuilt my lab controller and moved the management interface to a new subnet. Somehow, the AP Multicase Mode IP under the General Settings was removed. Afterwards, my AP's radios would reset every 2-3 minutes. After comparing my lab config to production, I noticed the IP was missing from that field. Setting the Multicast IP to 239.232.78.1 fixed the issue.
