Cisco Wireless :: WLC 2504 / 3750 - Multicast Stub And Apple TV

Dec 17, 2012

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.

Cisco Firewall :: ASA5520 - Stub Multicast Router On ASA

May 28, 2008

I'm swapping out a PIX, IOS 6.3 with an ASA 5520 v8.  The PIX has the following 2 commands in it's config:
 
multicast interface outside
multicast interface inside
 
These commands do not exist on the ASA.  I do not wish to enable multicast routing.  What commands on the ASA are equivalent to the multicast commands on the PIX?

Cisco Firewall :: ASA5520 - Stub Multicast Routing And Forwarding?

Jun 26, 2011

I can't seem to find where in ASDM (6.4.1), can we configure IGMP forwarding? ASA5520(config-if)# igmp forward interface outside The ASDM doc reference does not seem to be correct pointing to:configuring Stub Multicast Routing  

Step 1 In the main ASDM window, choose Configuration > Device Setup > Routing > Multicast > IGMP.
#Step 2 In the Multicast pane, check the Enable Multicast routing check box.
#Step 3 Choose MForwarding.
 
which generates:
 
ASA5520(config-if)# mfib forwarding

Cisco Switching/Routing :: 3750x Stack - EIGRP Stub With Non-stub Neighbors

Sep 16, 2012

we have 5 sites connected with a combination of direct fiber and Service Provider Ethernet. The equipmet consists of 3750 stacks with IP Services. Currently each site runs full EIGRP and is a EIGRP neightbor to all the other sites. Everything is working fine right now.
 
We would like to upgrade the R5 site to a 3750x stack with IP Base (cheaper than IP Services) and configure it as EIGRP Stub. My concern is with the following statement in the IOS command reference guide. 

Note Multi-access interfaces, such as ATM, Ethernet, Frame Relay, ISDN PRI, and X.25, are supported by the EIGRP Stub Routing feature only when all routers on that interface, except the hub, are configured as stub routers.

Cisco Wireless :: 1142 Multicast Setup / One Subnet To Enable Apple Air-Play

May 3, 2012

I’m having issues with enabling Apple’s AirPlay services on a relatively simple network consisting of a Cisco 881 (Advanced IP Services) and an autonomous Cisco 1142 AP. I’ve attached a diagram explaining the connectivity. I believe I have to enable IP Multicast at the router, but I’m not really sure the best/right way to do it. Also I’m not sure what/if any commands would be needed at the AP.All of the wireless clients are confirmed to be in the same subnet, so no real routing is happening etc. Also regular Internet connectivity/routing from the wireless clients is fine.

Cisco WAN :: 3750 / EIGRP Stub At The Edge?

Apr 24, 2012

I am looking to implement 25 Cisco 3750 switches with IPBASE image at the edge, across many cabinets.  I understand I am limited to EIGRP Stub on the 3750 switches (with IPBase) and cannot acheive funding to upgrade to IPServices.  Though I am not fully aware on the limitations, in terms of what I am trying to acheive.
 
Broadly speaking I want to install 2 x 3750 switches at the edge, with point-to-point links to two 6500 core switches (at the data centre) and then have HSRP interfaces on the 3750's, tracking the up links to the core switches.  I am presuming this will be the best solution to ensure reliability.My 6500 switches run EIGRP and have many VLANs and other L3 networks advertised, which will need advertising to the 3750 switches.  I would be looking to advertise two or three HSRP networks on the 3750 switches, up to the core switches.At the moment, the entire network is Layer 2 (VLANS + STP).
 
how to configure EIGRP across the 3750 switches and 6500 switches to allow for the 3750's to see the whole network and also advertise back up it's directly connected (HSRP) networks to the core.  At the moment, after configuration, none of the switches see each other as EIGRP neighbours but can ping the L3 addresses on each end.

Cisco :: 4500s / Enabling Multicast For Apple TV?

Mar 11, 2013

We have a pair of 4500s set up as HRSP pair. We have many VLANs set up. In one of the VLANs is a working Red Hat cluster which uses multicast for its heartbeats. The VLAN interface on each switch has ip pim sparse-dense-mode enabled on it. Multicast routing is not enabled.We now need to be able to send multicasts across a few VLAN to allow apple TV to work with our WLC and lightweight access points.
 
I assume I can just turn on multicast routing and enable ip pim sparse-dense-mode on the VLANs I need.Is this the case and will it have any effect on my current multicast traffic?

Cisco Wireless :: WLC 5508 To Use Apple Bonjour Service For Apple TV And IPads

Oct 22, 2012

A customer of ours has the following access points and wireless lan controllers on site.  They want to use the Apple Bonjour service with Apple TV's and iPads.  I have enabled multicast feature of the 5508 globally and one the SSID.The Apple TV has an ethernet connection and the iPads connect over the wifi.  The Apple tv is on the same subnet as the iPad's - the Bonjour features do work for approx 5/10 minutes then it stops working for some reason. The Access Points plug into a Cisco 2960 Layer 2 switch, the 5508 controllers plug are in LAG mode and plug into a Nortel Layer 3 stack which I have enabled IGMP snooping.I've read that the Apple Bonjour service isnt designed to work on a multi subnet network - but both the Apple TV and iPad are connected on the same subnet.  Sounds like some kind of timeout but not too sure.

Cisco Wireless :: Connecting WLC 2504 With 3750-x Switch?

Aug 15, 2012

I connected my 2504 wlc with my 3750-x switch using port-channel. Later i came to know that LAG mode is not supported in 2500 series , so i removed port-channel from my core switch and connected all the 4 port in WLC to core without any port-channel. Is that recommended?
 
 one more thing is , from WLC i can ping tha management interface on my core. but i cannot ping the default-gateway of my dynamically created interface on my WLC to core(core is the defauly gateway for all).

Cisco Switching/Routing :: NTP Multicast On 3750?

Dec 10, 2012

I have a subnet with a GPS clock on it that connects into a Cisco 3750. The 3750 has another subnet hanging off of it that connects into a firewall then to a server. I need the server to get time from the GPS clock. Any way to pass the NTP through the 3750?  The 3750 has the 3750-IPBase code running on it so the multicast support is limited. I am under regulatory restrictions that only allow traffic to flow from the higher security level (were the time server is) to lower security level (were the server is). This prevents me from having the server go to the clock for updates.

Cisco Switching/Routing :: Multicast Setup On WS-3750-X

May 12, 2013

I've been handed a requirement to try and get a multicast server working on my setup. Trouble is, I don't know if I can with the feature set I have on my switches. What is desired is that a multicast server (stand alone, but network connected, obviously) be accessible by everyone on the local network (multiple V LAN's, multiple SVI's) in the building.
 
All users will be connected to the one switch stack, although some will want to be wireless (which is one of the separate V LAN's) - I don't care if the wireless requirement goes by the wayside - they can sod off. :-) The main purpose will be multicast, high quality video.
 
I have a single switch stack consisting of two (soon to be 3) WS-C3750X-48P switches running the IP BASE feature set.
 
Question - can I do this on IP BASE, or do I need to upgrade to IP SERVICES?
 
If I can do it on IP BASE, does anyone have any links/pointers to setup this properly? Currently installed IOS is 12.2(58)SE2.

Cisco Switching/Routing :: Multicast On LAN Doesn't Work - 3750

I have PC_A and PC_B connected to the same switch, and are put in the same vlan. PC_A is the master (source) and PC_B is the destination (client). IGMP Snooping is enabled by default.
 
Is there any reason why this should fail? There is no RP or any interface with PIM enabled. Its a flat network with a source and client in the same vlan...

Cisco Firewall :: Multicast LAN With ASA 3750 And IP BASE LAN Internal Router

Jun 7, 2011

I have a LAN with multiple VLANs connected through Catalyst 3750 with IP Base image. In IP Base the router only supports PIM stub multicast (no PIM multicast routing),But I have an ASA connected to the internal router and to the internet router.Asa supports PIM multicast routing and can act as PIM RP. With this configuration, is there a way to configure an internal multicast network? That is a multicast server in one internal vlan (VLAN 1)  and multicast clients in VLAN 2. Both VLANs connected to the C3750 router.

Cisco Switching/Routing :: 3750 - Transition From Multicast Dense To Sparse Mode

Jun 19, 2012

A multisite network is currently supporting muticast using PIM dense mode, which is enabled on router/switch LAN and WAN interfaces across all locations. I am about to introduce Nexus switches to the main LAN. How can I make dense and sparse mode coexist to ensure flow of muticast traffic between devices supporting and dense and sparse mode? Eventually, I want to transition  to the sparse mode; however, it has to be done gradually, even within a single site. The leacy equipment includes Cat 3750 and  4500s.

Cisco Switching/Routing :: 3560 - Advertise Default Routes From EIGRP Stub?

Feb 13, 2013

I have a 3560 with IP base that is acting as a true EIGRP stub router today.  It advertises local routes to the upstream service provider router and receives a default route.
 
Now I want to connect a 3900 ISR as a voice gateway.  The 3560 does not seem to be advertising any routes to the 3900.  Ok the EIGRP stub doc says this:
 
Only specified routes are  propagated from the remote (stub) router. The router responds to queries  for summaries, connected routes, redistributed static routes, external  routes, and internal routes with the message "inaccessible." A router  that is configured as a stub will send a special peer information packet  to all neighboring routers to report its status as a stub router.
 
# Any neighbor that receives a packet informing it of the stub status will  not query the stub router for any routes, and a router that has a stub  peer will not query that peer. The stub router will depend on the  distribution router to send the proper updates to all peers.
 
I guess I don't understand why the stub advertises local routes to the upstream ISP router but does not seem to advertise routes to the 3900.  Does the stub identify the ISP router as the distribution router somehow, thus differentiating it from the 3900?  If so, how is this done?
 
show ip eigrp neighbor detail on the 3900:
 
EIGRP-IPv4 Neighbors for AS(100)
H   Address                 Interface       Hold Uptime   SRTT   RTO  Q  Seq
(sec)         (ms)       Cnt Num

Cisco Switching/Routing :: GNS3 - Stub Router Not Updating Routing Table - EIGRP

Nov 14, 2012

We have small which I'm looking to implement and have built this on GNS3.
 
We have:
 
Router A in site 1
Router B in site 2
Router C in site 3
 
Router A and B are connection via a point to point 100M link and from Router C we have a 2 point to point one of which is 5Mpbs and going to Router A and Router B.
 
For Router C to reach Router A network it will go via Router B and these are 100M connection. When the link between Router A and B goes down. Router C should update and start using the 5m route.
 
For some reson, the routes are not updating. I have to do 'clea ip eigrp ne' for the routes to update and if I reload the routers all works well, it seems the problem is intermittent.

Cisco Wireless :: 5508 - Apple IOS Devices

Jun 14, 2012

I'm seeing a problem with Apple IOS devices connecting from one SSID and then connecting immediately to another. I've tried to replicate this fault with non Apple IOS devices, but I'm unable. 

Environment:
Single 5508 WLC running 7.2.110.0 AIR-LAP1142N-A-K9 AP's
 
WLC is in clients head office, MPLS to their branch sites. AP's are in Flex Connect mode, with AP and Flex Connect groups for the AP's at the branch. 3 x SSIDs; Corporate (802.1X), Guest (Web-Auth) & Non-Corp (PSK).
 
Scenario:
Client is connected to the Corporate SSID with his iPad (new model, running iOS 5.1.1). No problem with access, he is able to roam throughout the building with good SNR/RSSI. He wants to test the other SSID's, he attempts to connect directly to the Guest or Non-Corp and gets an error message on the client saying 'Unable to Connect' or 'Unable to Join'. Debugs on the WLC for the client shows no connection attempt, no errors. I can see the client disconnect from the Corporate SSID, but nothing for the Guest or Non-Corp SSID.
 
If the client then disconnects and forgets the Corporate SSID from the wireless profiles on their i Pad, waits 20-30 seconds (I can see the client disconnect cleanly from the WLC) and then attempts to connect to the Guest or Non-Corp SSID's - he doesn't have a problem. He immediately associates, and is able to connect. If he then tries to connect directly to another SSID, while still associated to another from the same WLC/AP – he gets the error again. Forget/wait 20-30 seconds, attempt to connect – no problem. We've tested with several i Phones (4 & 4S), i Pads (2 & new model) - all running the same Apple IOS (5.1.1).
 
I unfortunately can't do much troubleshooting with TAC on this as the client is no longer onsite, and I don't have a 5508 in our lab that I can currently test with. I've tried playing with beacon intervals, etc to no avail.

After a few hiccups the router works with all of our computers, blackberry's, wireless printer and Ipod touch's however my Apple TV 1G will not connect to the network. The Apple TV will just give the error code -6 after the password for the network has been entered. I double checked that the password for the router is only WEP 10 hex digits and that it is correct have tried reseting the Apple TV to the factory settings and using the DHCP Reservation in the network settings of the router and manually configuring the TC/IP settings on the Apple TV (Not quite sure what I am doing with this though so put everything back). I have also tried switching the 802.11

Cisco Wireless :: 7.0.220 / Apple Clients Authenticated But Show No Username In WLC

Clients in this state are usually Apple products. From initial investigation it looks like the do authenticate with the ACS. r debugs to run, or fixes on the WLC? Perhaps there's a bug on this behavior?

We are trying to connect an apple tv, so we can stream picture, videos etc from ipads and Macbooks to a large display for media teaching.The setup works at home, but not at work.The apple TV is on the same network as the wireless apple devices, (we use a 10.6.4.x-10.6.5.254 range), both are dhcping the addresses (have tried fixing but that made no difference). I've enabled multicasting and igmp snooping and set the multicast address as 239.0.0.0 and it still doesn't work.

Cisco Wireless :: 2800 - Connecting To Wired Apple TV Across WAN Link

Feb 7, 2013

I am having issues figuring out how i can make AppleTV,Airprint, Airplay, etc show up on Ipads that are connected to the wireless network.  The controller is at a main site which is seperated by 2800 series routers at the remote sites over 100Mbs links.  Ipads connect and tunnell back to the main site.  I've tried enabling FlexConnect but the devices still get the main site's addressing so i'm guessing they are still tunneling unless the AP loses connectivity to the controller.  I have two SSIDs (staff and students).  I have tested with just setting the staff to FlexConnect.  Do I need to set both SSIDs to FlexConnect to make them dump data locally?  AppleTVs are connected wired to the local networks and get addressing associated with that building.
