OK, in this is it necessary to configure "IP Multicast-routing" on the switches? Do I configure PIM on all interfaces that will handle multicasting (router and switches?) If PIM is enabled on the 3750 do I need PIM configured between the 3845 and the 2821 ? Do I configure the Auto-RP on the 3750 or the 3845 ?
We have configured multicasting for our Nexus 5K switches. and for the most part everything seems to be working until recently.
Setup is we have 2 Nexus 5k switches connected via Dark FIber from Site A to Site B. Site A is sending the multicast traffc and Site B is receiving it.
I am not a network person, but I am not sure our Network Team is qualified either. For a long time we have been using a dying Cisco 2950 100/MB switch for imaging our computers using GhostCast. Multicasting on the 2950 was never an issue other than it was flooding the switch and making all the other ports unusable. But at least the multicast portion was imaging with decent times. We had two Intel Pro NICs teamed to get 200 MB/s and a typical multicast session was about 6.5 minutes. When using only 1 NIC, it takes about 8.5. Running two concurrent unicast or multicast sessions, well that is a different story. It then triples or quadruples the time.
Now we have a 3560G setup. A single session takes a little over 3 minutes. If we multicast off of this switch, the time is about 12.5 minutes. That is 4 minutes longer than the 2950! If I run 3 concurrent unicast sessions, it takes all of them between 3.5 to 4 minutes. So obviously there is an issue with multicasting.
The switch is in a lab separate from the production network. The server with our ghost images is plugged directly into the switch and so are the computers we are imaging. From what I was told from the Network Team is that IGMP snooping is on, but multicasting is off. He said that multicasting does not need to be turned on since all traffic is going through the local switch. Probably true since our old switch didn't have multicast turned on either, but it still imaged using multicast faster.
Below are some screen shots of the imaging. The first one is the 2950 using multicast to 3 laptops. The second one is the 3560 using multicast to 3 laptops. Finally is the 3560 using 3 unicast sessions to the same 3 laptops.
Currently we do not have multicat routing enabled on either of our 2x Sup720-10G 6509 Switches. We have no intention of doing so either. I am looking for clarification on how mutlicasting operates within a Vlan.
IOS: s72033-ipservicesk9_wan-mz.122-33.SXH2a.bin
Our Vlan has IGMP snooping enabled. Here is the output.
6509Switch#sh ip igmp inter vlan 25 Vlan25 is up, line protocol is up Internet address is 10.1.1.254/24 IGMP is disabled on interface
we do not want to disable IGMP due to this one concern that I can't find documented. If we disable IGMP snooping on the vlan, what happens to multicast packets with a TTL > 1. Do they get flooded to the entire switch and all Vlans? Or does it stay within the Vlan?
If we have 2 Cisco 2504 series wlcs and use multicast features in both and both are primary and secondary for LAPs. what about of we use multicast ip address let's say 255.239.1.60 can we use the same ip address for the secondary controller too or we should use any other ip ?
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 plan to implement multicasting on our network where the sourec and destination are going to be in different vlans.I have a test 3750 switch, Layer two multicast works fine, when I place the source and destiantion in different VLan it fails. [code]
Within our small lan we have a core 3750, that handles our intervlan routing and is the core of the network. I recently looked into multicasting and set up a lab test with a 3550 with an EMI image and got the config to multicast to all vlans from one vlan, ready to go, at which point I found that our 3750 is IPBASE and doesn’t support multicasting. Currently upgrading the switch or image is not an option due to funding. My question is would it be possible and advisable to install our lab 3550 as a leg off the core, and in some way route multicasting traffic through that?I just cant get my head around the concept of having a core switch essentially routing all vlans, and then having another switch route the same vlan traffic again for multicasting to all the vlans again.
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: Is there any way to use Multicasting without turning off IGMP Snooping on Switch side?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.
How do i enable InterVLAN MultiCasting. I have a WS-C3560G-24TS as my core switch and it does InterVLAN Routing. I have a Server VLAN (70) and Workstation VLAN (71). I have a server that i have set up to deploy images to computers. Up to this point i have only done one computer at a time, so unicasting was ok. I would like to be able to Multicast to multiple computers, but am unsure what i need to do on the switch (if anything) to enable this.
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've got a DIR-655 that I use as a wireless access point/switch (dhcp off) behind my Actiontec Verizon Fios router. The DIR-655 is in the basement and has my PS3 and Xbox hard wired to it.I've got playon server setup on my pc upstairs which is connected wireless to the Actiontec router. If I connect my ps3 wirelessly to the Actiontec, it immediately sees the playon server and streams movies without issue. However, when I hardwire the PS3 to the DIR-655, it will not pickup the playon server connected to the Actiontec router.I've got dhcp turned off and multicasting turned on under advanced settings of the Dlink.

We have recently implemented Windows Deployment Services on our local network, but everytime we do a multicast image deployment the network get flooded to point of total saturation.
We have Netgear switches and a Cisco 2800 series router. IGMP Snooping has been enabled on all Switches, however, we are unsure on how to implement multicasting on the router.
The whole network is flat - no VLANs over than the default VLAN1. We only want multicasting to work within our local network and does not need to go out the other side of the router as that is the connection to the internet.
How to get the Cisco router configured properly to enable multicasting to not flood the network. It seems that even if we were to image 4 PCs using multicast this is enough to completely get the network flooded.
Also, am I right in thinking that IGMP needs to be enabled on all of the Switches?

Platform: LMS 3.2.1 with RME 4.3.2 on Windows 2003.I'm having a problem with several devices that were backing up fine until this week - suddenly they aren't backing up their running configurations, but RME is fetching their startup configurations fine and VTP backups are fine. At first I thought it might be timeouts, so I used inline edit to incease the telnet timeout for a device to 180s. However, the job fails well within this time period (debug shows on i/o error?). My order of protocols is SSH, Telnet, TFTP. I took a stab in the dark that this suggested a database problem so I picked one at random and deleted it from DCR, and readded it and it worked. However, for the other 48 devices affected it did not.
I'm wondering if I need to do anything to the RME database to get things back to where they were? Do I need to reinitialize the RME database, and if I do that what do I lose? [code]
I was recently given a Cisco 7200 VXR and told to erase the stored configurations in it. how to do erasing of Cisco 7200 stored config else I might have to delete them line by line.
i have few devices in Cisco works, when i try to view their configuration. i get this error.DCMA0011: No configurations archived for the device(s). The selected device(s) should have at least one archived version.
I have this firewall working as active/standby. Everything seemed to be ok, but we noticed that confirgurations are not being replicated by saving configuration either copy run start or write. The workaround here is write standby command. Below the configs and stats, plus the show version, which is the same in both equipments:
We upgraded to Cisco LMS 4.2.1 recently and we have noticed that every time we reboot our Windows VM Server the archived configurations from the network devices are no longer displayed. They do not appear in the archive, version tree or directory. We are meeting the minimum system requirements for running LMS 4.2.1 and we do not seem to have found any possible bugs related to this.
We have a number of 2651XM with WIC-1ADSL. These are supplied by another company and we do not have access to the configs.We are told that the maximum througput from the ADSL WIC to the FastEthernet 0/1 is 2.5Mbps ( "it's a backplane issue" ), even though the ADSL speed reported by the router on the external interface is 8MbpsT
We are deploying over 20 RV180W Routers for a client and need to find a faster way to configure them for shipping.We have created a base image (all settings that will be shared between the 20 locations), we need an easy and quick way to make IP changes for the 3 VLANs and Local Security Groups for the IPSEC VPN.I tried to edit the CFG file by hand, but the checksum fails when it is loaded into the RV180W.How can I accomplish this? Can I manually create the checksum?Can I remove the checksum?
I have an ASA 5505 without any IPS module.While copy/pasting some configurations from another 5510 with IPS I copied my mistake the some of the IPS configurations part. Now I can't remove it.When ASA starts I get this Warning:
...WARNING> IPS policy is configured without an SSM card. *** Output from config line 828, " ips inline fail open"
Those lines are:
policy-map Outside_Policy class IPS_class ips inline fail-open
When I try to do "no ips inline fail-open" I get an "invalid input detected".If I try a no class IPS_class I get that is being in use.What can I do to clean up those lines?
I am using Cisco Works LMS 4.0 for collecting configurations of the devices. After changing the configuration of the device what is the minimum time that LMS detects the configuration was changed and save (make archive) the new configuration in the LMS database ? (Periodic Collection and Polling are disabled). Which mechanism drive this process, SNMP Trap?
I'm trying to move some configurations over to an ASA5510 and some of the commands are a bit different than I'm used to (worked on old pix before)
I've configured the following on the device: Outside interface: 65.66.64.34/28 DMZ : 65.66.64.49/28 Inside : 10.2.3.3/26 ===========================
The current firewall has the below configured on it (old Juniper)
10.2.3.0/24 gateway 10.2.3.15 **10.2.3.15 is the IP for 3750 switch on the inside LAN** 10.0.0.0/24 gateway 10.2.3.4 **10.12.175.4 internal vpn- will remove later but thats a different discussion** 0 0 gateway 65.66.64.33 **to internet 10.0.1.0 gateway 10.2.3.2 **10.2.3.2 represents mpls traffic
[code]...
The current set up for this network has an mpls router and a vpn concentrator as part of the network my aim currently is to replace the juniper with an asa5510 the changing of the vpn tunnels will be for a different time:
work station ===> switch (3750) DG to =====> MPLS (vendor owned and managed) ====> non mpls traffic ====> vpn concentrator ===>firewall ===> router
The above will need acls to go with the routes, which I should manage ok just want to make sure the routing is configured properly
I have an issue with the LMS 4.0, i added manually the ASA Fws 5520 and 5510, and i see them there, but i cannot see the configuration, inventory and technology details.Telnet is deactivaved in ASA´s, ssh and snmp v3 are enabled.Routers and switches were added without issues.
