Facing a problem of double multicast on one of our cisco 3750 switch. On checking with sniffer it was found that out of double packet’s one packet is having source mac-address of vlan and another packet is having a source mac-address of switch base mac-address.
View 3 RepliesI 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 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.
View 1 Replies View RelatedI'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.
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...
IH-3750-LOADTEST-101#show ip igmp snooping vlan 724
Global IGMP Snooping configuration:

IGMP snooping : Enabled

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.

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.
I have one server which run some application for wireless user. this server forward multicast packet to wireless user. server and wlc physically connect to cisco 3750 switch.i want the server forward the multicast packet to wireless users.server access vlan 4.wlc controller have 2 vlan: 90 and 110.and wireless user some of vlan 90 and some of vlan 110.i enable igmp snooping on wireless controller. and enable globally command but it is not working.which additional configuration i need on cisco switch.
Switch(config)# ip igmp snooping
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.

View 2 Replies View RelatedI have inherited a Cisco VPN 3005 and need to configure an interesting scenario:
2 LAN-2-LAN tunnels: 1 required an outside IP and has an existing static NAT of 192.168.1.1 -> 12.2.1.1 for 0.0.0.0 as the destination.I now have a need to created a new NAT for 192.168.1.1 to translate to 10.99.1.1 for destination of 13.3.1.1, 14.3.1.1 and 15.3.1.1.
Is it possible to have the above scenario, or even NAT 12.2.1.1 from the first NAT back to 10.99.1.1??
I have two RFC1918 domains I wish to connect, can I use double NAT with PAT so that each domain is represented as one single ip address with each session a port of that address-
The link is a private point to point link with a /32 mask so could I use this as the PAT address ?
I am setting up a new ASA running 8.3 and I am having problems with configuring double NATs.
Here is the thing I am trying to solve:
Original Packet
SRC: 1.1.1.1
DST: 1.1.1.10
After it hits the firewall and it comes out on the outside interface I want this:
SRC: 2.2.2.1
DST: 2.2.2.10
Now when I set this up the way I did in 8.0(4) it just ain't working.
All the NAT examples I can find are simple NATs, I have not been able to find an example of a SRC and DST NAT.
i bought me a router so that me and a few other friends could play to star craft 2, but i would like to know that if i could play an LAN with NO internet on it?

View 2 Replies View RelatedWe just upgraded our Sg300 series switches to the new IOS so we can get CLI access. The upgrade went fine but it seems we have two login prompts, the first being completely unnecessary as you can just hit return to get by it. IE here is the progression:
1. Connect SSH
2. Receive a "login:" prompt. Anything can be entered here, including just return
3. Login banner is displayed
4. Username Prompt is then displayed. Valid username required
5. Password Prompt displayed - Valid password required
6. Now at CLI 1. Connect SSH
I am trying to get rid of that first login prompt (IE Step 2) as it is causing issues with our configuration software. I have tried every line and authentication command I can think of, the only thing that gets rid of it is using none authentication which obviously we can't stay with. how did you get around it?
is it to increaze the broadbandwith by using a double usb-modem dial-up ...i know tha we can use double connection, but not in real time...

View 3 Replies View RelatedThis is my Cisco LAB environment used for study but also in production for daily use. I am trying to setup a double-NAT network with just one IP from my ISP through the ASA & 3825 going to (2) end nodes and multiple ports for port forwarding. It is currently working but only as simple PAT and I cannot initiate FTP from the outside. removing the router, but this is my study LAB and it's a bit unconventional for learning purposes. I attached the diagram and need parts of the config.
View 14 Replies View RelatedI'm currently switching from a certain internet provider to another and I'm forced to get another router. What I wanted to do is since the initial router has to be on the first floor, I'd like to have the second one on the top floor closer to my computer whereas they would share a dedicated connection between each other wirelessly so it would make my connection faster rather than just having my pc connect directly wirelessly to the initial router on the first floor. Is that possible?
View 4 Replies View RelatedI only have access to rather slow connections (256 Kbps). But since I have two lines and two modems, I was wondering if I could bond them together and make a faster one. My main modem is a Lynksys WAG120N Wireless-N ADSL2+ Modem Router, which as you can see is also in charge of both wired and wireless networks at my place. The second one is an older D-Link ADSL modem (JUST modem).Since I have an extra LAN port on my Lynksys modem, I want to know if and how I can connect the second modem, and combine the two rates.
View 2 Replies View RelatedI'm new to networking (at least at this level) and need some guidance. First, I have an Actiontec MI424WR (Rev. F) Coax Verizon Fios modem that I use as my home networking wireless router. From a LAN port on that I've connected a cable to the WAN port on my DIR-655 which acts as my gigabit office hard wire/wireless router. I need to keep the home network and the office network separate.All of my computers are Windows, either 7, Vista or XP.Connected to my Dir-655 on the office network are 2 wireless computers, a printer, an IOMEGA 1TB Home Personal Cloud NAS HDD, plus 2 desktop computers.The DIR-655 is set with a static IP address matching the range of the Actiontec. The DIR-655 is set for DHCP for the devices on the network (although 2 of the computers have static IP address).
When the DIR-655 had a Dynamic IP address set by the Actiontec, the IOMEGA NAS HDD kept losing connection with all the devices on the network. Only after I set the DIR-655 to static IP did that stop and everybody started to play nice. I'm not sure why that would make a difference, but it did.But regardless of whether it is set to dynamic or static, no computer on the network or program, even third party programs, can connect to ANY of the time servers out there... and I mean any of them. I've tried at least 20 or more of the standard and not so standard ones. The DIR-655's time is off, and it is set to get time automatically. None of my computers, or my IOMEGA NAS, can access time. The Actiontec, though, seems to be set correctly.Everything connects to the internet just fine. Web, email, auto product upgrades. Fine. So far it's just the time server thing which troubles.I done everything I know how to do to enable Port Forwarding through both routers for NTP > UDP 123 since that is the standard port for the Network Time Protocol, but I could have easily screwed that up.
On our 6504 - 12.2(33)SXH, we currently have a single connection to our ISP (GI1/1) and want to add another connection (GI1/2) Is there a way to bond the two connections to form a single connection (a single pipe) to double the throughput?

I have an HP C5280 printer running wirelessly via a TP Link wireless print server and D Link Di 624 wireless router. I can print successfully from either my desktop (which is connected direct to the D Link router) or either of my laptops (wireless). However, when I select the double-sided print option I get a print error message after re-inserting the odd number pages to print the other side of the paper and then click 'continue'.Could I resolve this by connecting the printer both direct to the desktop using USB AND leaving it connected via the wireless TP Link print server? This would enable me to print double-sided from my desktop (as I did before when the printer was only connected via the USB desktop port).
View 1 Replies View RelatedI'm suffering from an annoying problem with my E4200 router. I have a DSL connection. I have my DSL modem in bridge mode and I have my router set up to sign into my ISP's PPPoE to avoid double-routing. This set up worked marvelously with my previous WRT54G and WRT610N routers.Now the E4200 signs me out of PPPoE every ten minutes or so. I have the connection setting on "Keep Alive" but it seems to be dropping the connection regularly. I took the router back and was given a replacement. The new router is doing the same exact thing and now I am beyond the 30 day return limit so I'm stuck with the E4200. I'm running the latest firmware 1.0.03
I reinstalled the WRT610N and the connection is steady but the WRT610N has its own problems (devices connected via wireless cannot see wired devices and vice-versa). I'd like my new router to actually work properly. I've ruled out errors on my end and given that two brand new units of the E4200 generated the same problem I tend to believe it is a design error.
I have a problem with my home network/internet - I have a working wireless network that I have used for some time now and it works just fine. the problem is that internet restrictions where I live require me to register each unit to the building network before I can gain access to the internet. My caretaker told me today that normally, I only should register my primary computer and the wireless router to be able to use the internet freely. However when a new laptop appears( I have a guest), I can easily connect it to my own wireless, but it can't use the internet, as if it needed to be registered again. I ran out of registration codes and I really would like to have freedom i connection opportunities. The caretaker said that the system gives every registered unit a "fake" IP, so after giving it to mu router, all other units connected through that router should have unlimited access. Is my network configured in a wrong way? I don't know how to ask this in a more simple way... I just want to be able to connect a friends laptop to the net with just my local password, which isn't happening.

View 3 Replies View RelatedThe desktop team has asked me to set up multicast in our network with building PC's as they will be deploying a few hundred of them starting in two weeks. We currently do not have multicast set up, and the only experience I have with it was during my certification studies, so I have a lot to catch up on quick. They will be sending the build traffic from a single server. The network environment is simple: a 3750 stack as the router/distribution layer and mainly 3550's as access. The PC's that they will be imaging will be on one VLAN that is already designated for PXE builds. This VLAN is across multiple switches. Is it possible to just enable the multicast features on a single VLAN? I have been reading around but not finding much other that very in-depth Cisco papers.
