Cisco Infrastructure :: IGMP Snooping Configuration For Multicasting On Catalyst 3020
Nov 24, 2011
IGMP Snooping configuration for Multicasting on Cisco Catalyst 3020
Our switch model is "Cisco Catalyst Blade Switch 3020 for HP" We are building HA (High Availability) Databases infrastructure. Currently, there are two nodes(hosts- servers) and two above switch for HA.
Oracle said we need to turn off the IGMP Snooping in order to use the multicasting for their interconnect communication. So my question is:
Q1> Is there any way to use Multicasting without turning off IGMP Snooping on Switch side?
Q2> If 'yes', how can we configure the switch for Multicasting ?
Oracle uses 230.0.1.0 & 224.0.0.251 IPs with 42000 range port for Multicasting communication.

I have to deploy a full IP-TV solution and the IGMP snooping must be supported on the switch.
I know the the ESW 520 support this protocol but the full IP-TV solution will manage uo to 200 set up boxes, does this switch support all this traffic?
I also have another question, what exactly mean "Combo SFP slots include one 10/100/1000BASE-T Ethernet port and 1 SFP-based Gigabit Ethernet slot for fiber, 1 port active at a time." ? Is when I use 1 port with LX sfp transcever the 3 other uplink ports will be inactive and I can't add another or trunk it with another switch?

i want to setup IGMP Snooping on the Managed Switch SG 300-10. I do it over the webinterface. Enable Bride Multicast Filtering, Forwarding Method IP Group Address and enable IGMP Snooping v3. In the local Network i stream up to 4 Multicast streams 239.1.1.1-239.1.1.4. The client vor the Multicast are IP setupboxes. If i connect PRTG Network Monitor over SNMP to see the Traffic on the ports i see that all Multicast streams are at every port. What is the false i do? I thought only the multicast stream that is shoosen at the client are forwarding and not all multicast streams. The IP STBs have only a 100Mbit network adapter and i have to muticast over 10 Streams (10Mbit per stream) over the local VLAN. So i think IGMP Snooping is the solution for me. Or need i also a Multicast router?

I have a network which is based upon a 4507 Core/Dist switch, with 1G fibre to a bunch of radially connected 2960 Access switches. It all works fine and as expected for data and telephony.I have been tasked with setting up one of the VLANs to support multicast, so a bunch of video streams will be injected at the 4507, and will be delivered to client PCs connected to the 2960 switches.The 4507 is running with SVIs to some VLANs, but the VLAN that will have the Multicast on it is isolated, with no SVI.I could change this if required,I need to run IGMP snooping, and probably deploy CGMP to take advantage of the Cisco-proprietary functionaity.

I have some problems with IGMP snooping feature on the SG300 switch. I want to filter multicast dinamycally with IGMP snooping. To configure our switch I use the web page: - In Multicast I first enable: Bridge Multicast Filtering Status Thzn I enable IGMP snooping ,Then I enable IGMP Snooping on my VLAN During my tests I stream a video (UDP multicast). This stream is present on all the ports of my VLAN with IGMP snooping normally configured. Also, I can't see any entry in the IGMP/MLD IP Multicast Group Table where I should normally see my multicast address.

how to configure igmp snooping on a 3560.
I have a pure L2 switching network and 2 hosts on the same vlan that want to communicate a protocol between each other using multicast packets.
I wanted to configure ip snooping only on this vlan and create a multicast group limited to only these 2 host ir order to make sure that the multicast traffic is only between both of them.
Since both are sender and receiver I´m not quite sure on how to configure this. In theory I also need to set an IP Multicast Address on the switch to where the hosts will send their multicast packets.
This is basically the network:
HOST_A---|SWITCH_A|==|SWITCH_B|---HOST_B

In the following topology
R1(f0/0)------------(f0/1)SW1(f0/2)------------R2
R1 is configured as host (no ip routing) with ip igmp join 239.10.10.10 on fa0/0 and R2 with ip pim sparse-mode on f0/0. SW1 is a Catalyst 3560 running IOS 12.2(25)SEE4 working at Layer 2 only in this topology (VLAN 1).
I configured SW1 for igmp snooping:
ip igmp snooping
ip igmp snooping vlan 1
Basically, I can see 'snooped' muticast group (via IGMP reports sent by R1)
SW1#sh ip igmp snooping group
Vlan Group Type Version Port List
----------------------------------------------------------------
1 224.0.1.40 igmp v2 Fa0/2
1 239.10.10.10 igmp v2 Fa0/1, Fa0/2

I've got a pair of Nexus 7010's running vPC. I am having a Multicast issue with a cluster of Linux servers that need to talk Multicast for cluster/high-availability operation. All the servers need to talk to a single multicast address and I am having trouble getting them to communicate. I believe I need to enable IP IGMP Snooping Querier on the N7K's and it needs to be enabled on the VLAN where the servers reside. How to enable IP IGMP Snooping Querier on a VLAN ?

I've been looking into IGMP snooping and have read that a L2 switch will forward multicast traffic to all ports connected to an interested receiver AND all mrouter ports. In a L2 'V' topology this results in all multicast traffic routed onto a VLAN being forwarded to the 2nd distribution switch. My question is how should a 6500 Sup720 deal with this unwanted multicast traffic? Both a Local SPAN of the RP and a Netdr capture suggest that this traffic is punted to the RP and ultimately dropped. Is this expected behavior or should the traffic be dropped in H/W?

It act's about the CISCO WC210 WLAN Camera.
We are using the WVC210 WLAN-Cameras (URL), this camera has a web server, so is accessible over a normal web-browser, to see the video transmission.
We just set it up with a normal WLAN-Router, so the camera is connected wireless to the router, and this router is connected to the internet (WAN). With the cisco video-software or the web-interface, it's now possible to stream the video.
Now we like to stream the Video on our Website, so people what visit our site can take a look at our company and so on.We are able to stream the Video with the MJEPG-Format, like the camera web-interfaces offers...
The problem is, with normal ip-transfer method, each user would connect directly to the camera and increases the data-transfer, the internet-connection will than overload easily.But the camera supports multi-casting, so the camera only transmit one data stream and all clients connected to this stream will receive the packages.
Our problem is, we do not have any knowledge about multi-casting and how it works, the camera has a normal ip-address and a pre-configured multicast address with group name, so how can we connect a client to this multicast group, without increasing the data-transfer with each new user? Would you recommend us to use the multicast function of this camera or put a server between the camera and the website?
How we can set up this multicast service and easily get a player for the stream on our website, without using many plug ins or special apps ?

We have 12 Catalyst Blade Switches 3020 for HP running IOS Version 12.2(55)SE. In the configuration of these switches I see the statement shown below.
no spanning-tree vlan 34,45-55,70,600,643,840,843-850
The 12 blade switches are configured as VTP clients and running VTP V2. I did not configure the statement shown above. It appered by itself. And even if I delete it, it will reapper. (The blade switches are interconnected to two 6509s. The two 6509s are the STP root and VTP bridges. I configure Vlans and STP on the 6509s).
why the statement above appers on the blade switches 3020s?
I mean I use other Cisco switches such as 3750s and 3560s and I have never seen the statement above appear by itself.

I have a new catalyst 2960,and i want to enable DHCP SNOOPING,but,it doesn't work,the server is stilling offert addresses IP and it's not connected in a trusted port,the schema is very simple:1 switch catalyst 2960 PST-S,1 server dhcp and 1 pc client,the PC and the server are in VLAN 10,DHCP SNOOPING is enabled in all ports and no port is trusted,but the client get addresse IP after retyping ipconfig /release and ipconfig /renew in dos commande.the configuration and the version of the switch are in the file attached.I tested the same configuration in a catalyst C3560-24PS and DHCP SNOOPING work normally,i tested in other catalyst 2960-PST-S,but the same probléme:DHCP SNOOPING without effect,the commands typed is:
-ip dhcp snnoping
-ip dhcp snooping vlan 10

We have a switch Cisco Catalyst 2900 Series XL Model WS-C2924-XL-EN. 8 MB DRAM 4 MB FLASH
I already tried the discussions regarding flash_init dir_flash: boot and the likes.
By the way, I already downloaded the IOS for our switch through Cisco Website. Settings are default through Hyper Terminal
Here's the thing:
Whenever I transfer the .bin file using XMODEM, it prompted an error "Transfer cancelled by remote computer"

I have a Catalyst 4006 with Supervisor II engine. I have 48 port 10/100/1000 blades installed in it for connection to my servers. I am having a lot of problems with performance when connecting servers that are using 100 MB NICs. The speed of the connection is really bad. I have attempted setting the ports and NICs to 100MB Full duplex instead of auto-detect, but still get the same results.
I also have a 10/100 quad-port card installed in a NetApp filer. All four ports are trunked together and connect to 4 ports in the Catalyst. The ports in the Catalyst are trunked using the Port Channel feature of the CatOS. When I look at the port statistics on 3 of the 4 ports from the quad-card, there are a ton of runts and errors (both transmit and receive). The 4th port is fine, no errors.

I need to configure on a cisco catalyst 6509 two VACL. On cisco 6509 there are already two SPAN ports configured, there are problems configuring other two VACL?
These VACLs send traffic to a Traffic Analyzer (SIEM), there are particular configurations to facilitate the operation?

We have the next Settings in our SW. We crate an ACL and aplied to a SVI for Incomming Traffic, I understand that is not necesasry to allow the returning traffic in ACL, but we can't access to rdp for example when we add the ACL, if we remove it, the acces is ok, buet when we add again the access is deny, even we have a log entry, and the ACL i just for Incomming traffic. There is no another ACL.

I have set up an ACL on my 3750 switch to deny icmp from PC A on our inside network to PC B on a different VLAN on our inside network using the following ACLs:
deny icmp host 10.1.17.15 host 10.3.10.4
deny icmp host 10.3.10.4 host 10.1.17.15
-- or --
deny icmp host 10.1.17.15 host 10.3.10.4 echo-replydeny icmp host 10.3.10.4 host 10.1.17.15 echo-reply
These ACLs belong to an access-list that also limits ip traffic to a few specific machines.When I try pinging from PC A I receive a reply message back from PC B. Shouldn't this configuration block any ICMP from PC A to PC B and from PC B to PC A? I would have expected the first ACL statement to block any packets associated with ICMP and when that didn't work I tried the second configuration.

I have several 2960s and 3750s and two 6506 (ws-cac-3000w) recently move to new location The power outlet is the same ,but Volt is different current 2960/3750 use this(one phase 3 wire) 220v and new location change to (from 3 phase 4 wire -> one phase 220v)6506 current using(one phase 3 wire) and will be change to (from 3 phase 4 wire -> one phase 220v)
I had search doc about power supply /cable , only show support single phase 220 v ,but not description vlot between each wire !!Does new location power outlet suit for 2960/3750s power and 6500 ws-cac-3000w ?!? Do I need chane power outlet back to current using?

I'm working for KOREA TELECOM, and currently providing MPLS VPN.We're planning to provide our customer with traffic report using NetFlow..
I read some documents which reads Netflow ver.9 can be enabled on Cisco GSR 12000 Series, but no mention about catalyst switches. Netflow ver 9 can be activated on catalyst 6500 series.. because the point where switch is located already have mpls encapsulated packet ( mpls vpn packet).
