Cisco Switching/Routing :: IGMP Snooping Configuration For Multicasting On Catalyst 3020
Nov 24, 2011
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 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.
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 SW1# SW1# SW1#
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 ?
We have a 3750 acting as the core. By default IGMP snooping is enabled on cisco 3750 from the documents.but, when we see the ip mroute table on the switch, it doesnt show any output.
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?
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.
when enabling multicasting on layer 3 interfaces the CPU becomes fully utilized , is there any specific configuration should be enabled to reduce this .
Config :
Inetface vlan 100 ip pim sparse-dense ip igmp version 3
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:
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.
I have got a catalyst cisco 2960G series switch and via this switch I want to creat serveral vlans. I am getting a dhcp IP from a router and I want to setup my own vlan networks.
I plugged in the Ethernet cable that came from the dhcp router to port 16 of the cisco switch and configured the ports 1,2 and 3 for vlan 1, 2 and 3
the dhcp router has given me this IP 192.168.10.158 defautl gateway is : 192.168.10.1
when I plug in a PC to port 1 or 2 of the cisco switch I still receiving the IP from range 192.168.10.* but not from the range that I configured for the vlan 1 or 2.
Below is my startup configuration:
no file verify auto spanning-tree mode pvst spanning-tree extend system-id
I have CISCO catalyst with VLANs (VLAN ID 33, 36, 40-53) configured. I need to configure port mirroring in Switch 3750 for NAC (Network Access Control). I need to Monitor all the VLANs. Here is the SPAN configuration of switch: [code] Monitor session 1 source vlan 33 , 36 , 40 – 53.Monitor Session 1 destination interface fa 1/0/8 (here I am not able to set encapsulation dot1q ) because the error occurred saying %one or more dest port do not support the encapsulation%.
I got problem with wake on LAN software.. The software unable to ON all pc's remotely if sitting under different vlan. Everything is ok if using the same vlan. Below are the network diagram & switch configuration.
Layer 3 switch Intervlan routing configuration
ip forward-protocol udp 7 ! interface Vlan4 description vlan Client-WOL ip address 172.22.51.253 255.255.254.0 ip access-group Deny_HTTP_Vlan1 in ip helper-address 172.20.1.246
[code].....
After configured all the switches with the above setting, the software still cannot wake all the pc's using LAN. Base on sniffing, i can't find UDP port usage by the software. Attached here with print screen from wireshark.
I am struggling with a CE520 and its smartports stuff.I have configured the following vlans :
1- data 100 - phones
I need to bring those vlans (both of them) to a Cisco 800 router. The port of the 800 router is already configured as trunk and accepts vlan 1 and 100.The cisco 800 has both vlan 1 and 100 configured with 2 ips on different subnets, and ip routing is enable (to route between two vlans). Also, no access lists are configured.I have configured one port in the switch as role "router" and connected to the router. The other ports are all configured as phone-desktop (phone vlan 100 desktop vlan 1).If I connect a phone and manually configure an ip (the phone gets automatically vlan 100), and try to ping the phone from the router, it doesnt respond. Alse vlan 100 is protocol down.I am guessing what s the right configuration as the link between the switch and the router should be a trunk link for 1 and 100 vlans, but it looks like is transporting only vlan 1.Also changing the port role to "other" when you can specify the native vlan and another vlan, the switch doesnt accept vlan 100 as additional vlan on that link.
I am migrating services from SUP720-3B to VS-SUP2T-10G= and moving to a VSS configuration between a pair of Cat6506 distribution layer switches. I need to enable QoS on these switches, primarily to trust dscp and also to prioritise voice traffic. The autoqos feature works for some ports but does not work on port-channel interfaces and port-channel member interfaces. How can I apply the qos settings for these interfaces in line with what auto qos would normally provide. My line cards are as follows:
Civic_6506VSS#sho mod Mod Ports Card Type Model Serial No. --- ----- -------------------------------------- ------------------ ----------- 1 4 CEF720 4 port 10-Gigabit Ethernet WS-X6704-10GE
I am connecting two catalyst 3500 XL switches via fiber fx ports for layer 2 connectivity. Do I need to configure anything in the IOS or do I just plug in the fiber?
Our servers are hosted at the Main site, site office A access to the Main site for Internet and servers. We are thinking NextG to take over when the link between sites goes down.
To start with, what is the configuration for 3750 at Site A and the Main site:
1) Trunking for both switches
2) Routing
3) the automatic failover configuration for the switch at Site A.
I have a WCCP Configuration on a Catalyst 3750G and a IronPort Webappliance. I have configured this situation many times before with cisco asa and ironport wsa, but with a switch, this is my first time.
VLAN 147 is a transportation vlan between the cisco switch and a hp coreswitch with the clients and servers behind the hp coreswitch.
VLAN 147 IP Address of the Catalyst is 172.30.47.1
IP of the IronPort Appliance is 172.30.47.10
IP of the HP Coreswitch is 172.30.47.2
Plan is to redirect the webtraffic coming from clients and servers from the 10.0.0.0/8 net behind the hp switch to the ironport wsa. In have configured these settings.

I was trying to configure my Catalyst Express 500 switch (PID VID: WS-CE500-24LC V01) and i followed the step i found in a document on Cisco website but still it showed an error "Page not found" and address displayed on bar was"169.254.0.1/catalyst-express.htm).
I was unable to configure vlan-based qos on Cisco IOS Software, s72033_rp Software (s72033_rp-IPSERVICESK9-M), Version 12.2(33)SXH6, RELEASE SOFTWARE (fc1) Seems to me my configuration is not working. Here is the output of the interface:
sh int G1/6 | i rate Queueing strategy: fifo 30 second input rate 25231000 bits/sec, 4282 packets/sec 30 second output rate 46940000 bits/sec, 9257 packets/sec
Why I can't see matches in ACLs? I've double checked the direction and seems to me it is correct. I can't see matches even I configure something like this:
10 permit ip host 192.168.1.168 any 20 permit ip any host 192.168.1.168
Why my output rate is higher than 30M? Is it bacause there is no matching traffic here in ACLs? I'm absolutely shure that this host with such ip connected to this interface:
#sh arp | i 192.168.1.168 Internet 192.168.1.168 0 feed.beef.f00d ARPA Vlan3 #sh mac address-table | i feed.beef.f00d * 3 feed.beef.f00d dynamic Yes 0 Gi1/6
I came across a Catalyst 6509 switch configuration and have noticed some strange thing on the ether channel configuration side, it appears that it have interface port-channel 2 and port-channel 2A, what was that mean? its the ether channel not forming and joined together?
What wrong with the below configuration that cause it to automatic created another port-channel (2A) interface in this case?
My company has acquired a Catalyst 6513 with a FWSM module installed on it. I have been reading lot of documentation on [URL], but still have some problems configuring the FWSM:
The 6513 has 10 SVIs configured, each of them with an IP address. These 10 SVIs are binded to 10 VLANs which I need to secure. These SVIs are used for routing all the Inter-VLAN traffic inside the switch. The documentation says it is recommended to use just one SVIs for connecting the switch to the FWSM, although you can use more than one using the command "firewall multiple-vlan-interfaces". I don't want to use this command because it seems a pretty more difficult configuration, since you have to use policy routing after using this command (or that is, at least, what documentation says).
When I try to "send" to the FWSM more than one VLAN that are configured as SVIs on the switch I get this error message:
"No more than one svi is allowed, command rejected."
If I delete the IP address of those SVIs, then I can to "send" those SVIs to the switch with no problem at all. But I need the SVIs to have IP address configured, since they are needed for routing Inter-V LAN traffic.
So, the question is: how can I route all the inter-VLAN traffic using just one SVI on the switch? Should I use the FWSM for inter-VLAN traffic routing?
I was wondering if I can force catalyst 2960 to skip startup config stored in NVRAM and boot with no config everytime it is powered. I tried to find it on google and in cisco white papers but still no luck. I found only commands that begin with "set boot config-register ... ", but switch acts like it does not know these commands.
