Configuring Cisco Switch VLANs for Samsung DLNA Sharing!

Hello there,
In my vlan 40, I have Samsung Smart TV and Samsung Allshare "DLNA" software on one of my PCs in the same vlan. Everything works fine and I can watch movies on my TV streaming from my PC.
Now, my brother, which is in Vlan 20, bought Samsung Smart TV.
I want my PC, which hosts Samsung Allshare software (vlan40), to send its media streaming to my brother's TV (vlan20) so he can watch my movies.
I know broadcasts are dropped between vlans.
So, How can I accomplish that?

Hi,
Have a look at this link:-
http://www.cisco.com/c/en/us/support/docs/ip/ip-multicast/9356-48.html
If your switch is doing the inter vlan routing (IE Layer3 compatable)
Then a simple DENSE mode config something like this should be OK.
ip routing
ip multicast-routing dist
int vlan 20
desc ***MY BROTHERS VLAN ***
ip add 192.168.20.1 255.255.255.0
ip pim sparse-dense-mode
no shut
int vlan 40
desc ***MY  VLAN ***
ip add 192.168.40.1 255.255.255.0
ip pim sparse-dense-mode
no shut

Alex

  • Can you Connect Cisco switch modules for to N2K?

    I have not seen anything about connecting Cisco Switch modules for Blade Chassis to fex.  Does anybody now if you can do that?
    thank you.

    thank you Lucien.
    I think you got a right name for N2Ks, a NIC card extender.  In my opion N2K should be able to support Blade switches. Not every company has just rack mount servers, most enviroment is mixed. In my case, I run out ports on N5K, but plenty available on N2K.  I want add two more blade centers with gig switch modules in them. now I have to buy a N5K!!!.  I'm sure Cisco can make N2K to support switches too.

  • Configuring Cisco ASA 5520 for Outlook Anywhere - Exchange 2007

    I have enable and configured our Exchange 2007 for Outlook Anywhere. When I try to get Outlook from home to connect it fails. We have an Cisco ASA 5520 firewall at work, is there something I need to setup on the device? We want to allow users from
    home to connect via their Outlook clients from home. OWA is working from the outside... Help please...

    Hi,
    Make sure that the required ports are allowed over he device. The users can access through port 25/443 etc. and should be opened. Better, to go for a test at www.testconnectivity.microsoft.com

  • IP changes on a Cisco Switch Module for IBM BladeCenter

    Hi everyone,
    I was just wondering if anyone out there is using the MDS modules for IBM BladCenters and if so whether you had had any problems changing the IP details through the BladeCenter management interface. I needed to change a subnet mask but since making the change I've lost all IP connectivity to the module and it shows Status: Disabled under the new IP Details.
    I've tried resetting the module to factory defaults and whilst this seems to have had some effect (e.g. the fc ports have all gone down) it has given me any IP connectivity or allowed me to set up a new IP address.
    Has anyone else seen this and if so, how did you get round it.
    Thanks,
    David

    Hi Mike,
    I saw that it doesn't allow you to change any of the IP config through the CLI, hence why I moved on to trying the MM.
    Fabric manager can't connect to the module on it's address (I was just correcting the subnet mask) and it is not pingable from anywhere on the network, so it seems to me that the IP path out through the MM isn't working.
    I tried the same process on one of our test chassis and the same thing has happened there.
    Configuration for that slot looks like this on the MM:
    Bay 3 (Fibre SM)*
    Current IP Configuration
    Configuration method: Static
    IP address: 172.20.221.9
    Subnet mask: 255.255.255.0
    Gateway address: 172.20.221.3
    New Static IP Configuration
    Status: Disabled
    To change the IP configuration for this switch module, fill in the following
    fields and click "Save". This will save and enable the new IP configuration.
    IP address 172.20.221.9
    Subnet mask 255.255.255.224
    Gateway address 172.20.221.3
    How does the MM communicate with the module (telnet/snmpv1/snmpv3/ssh?) and with what credentials. I'm thinking that there must be something in how we've configured the switches that is breaking this in some way (we've enabled aaa auth for login, removed some default SNMP details, and disabled the telnet server).
    There seems to be rather a lack of docs on these modules, is there anywhere to find out more detail on how they all hang together.
    Thanks for your interest and help,
    David

  • How to Configure Cisco ASA 5512 for multiple public IP interfaces

    Hi
    I have a new ASA 5512 that I would like to configure for multiple public IP support.  My problem may be basic but I am an occasional router admin and don't touch this stuff enough to retain everything I have learned.
    Here is my concept.    We have a very basic network setup using three different ISPs that are currently running with cheap routers for internet access.  We use these networks to open up access for Sales to demo different products that use a lot of bandwidth (why we have three)
    I wanted to use the 5512 to consolidate the ISPs so we are using one router to manage the connections.  I have installed an add on license that allows multiple outside interfaces along with a number of other features.
    Outside Networks (I've changed the IPs for security purposes)
    Outside1 E 0/0 : 74.55.55.210  255.255.255.240 gateway 74.55.55.222
    Outside2 E 0/2: 50.241.134.220 255.255.248 gateway 50.241.134.222
    Inside1 : E 0/1 192.168.255.1 255.255.248.0
    Inside2 : E 0/3 172.16.255.1 255.255.248.0
    My goal is to have Inside 1 route all internet traffic using Outside1 and Inside 2 to use Outside2.    The problem is I can't seem to do this. I can get inside 1 to use outside 1 but Inside2 uses Outside 1 as well.
    I tried adding static routes on Outside2 to have all 172.16.248.0/21 traffic use gateway 50.241.134.222 but that doesn't seem to work.   
    I can post my config up as needed.  I am not well versed in Cisco CLI, I've been using the ASDM 7.1 app.  My ASA 5512 is at 9.1.   
    Thanks in advance for the suggestions/help

    I have been away for a while and am just getting caught up on some posts. so my apology for a delayed response.
    I find the response very puzzling. It begins by proclaiming that to achieve the objective we must use Policy Based Routing. But then in the suggested configuration there is no PBR. What it gives us is two OSPF processes using one process for each of the public address ranges and with some strange distribute list which uses a route map. I am not clear what exactly it is that this should accomplish and do not see how it contributes to having one group of users use one specific ISP and the other group of users use the other ISP>
    To the original poster
    It seems to me that you have chosen the wrong device to implement the edge function of your network. The ASA is a good firewall and it does some routing things. But fundamentally it is not a router. And to achieve what you want were a group of users will use a specified ISP and the other group of users will use the other ISP you really need a router. You want to control outbound traffic based on the source of the traffic, and that is a classic situation where PBR is the ideal solution. But the ASA does not do PBR.

  • Configuring Cisco/IronPort plugin for Outlook with CRES

    With the discontinuation of the IronPort IEA appliances we are getting ready to move from our on-premise IEA appliances to CRES.  I have a demo key for Encryption that I am running on my C660s and I have an Outlook client configured with the Email Security Plug-In version 7.2.0.39.  Currently the Outlook Plug in is configured to point to our on premise IEA appliances for the Server URL attribute in Desktop Encryption Options and is working great.
    My question is, what do I use to connect it to CRES for desktop encryption?
    The Admin guide "Cisco IronPort Email Security Plug-in 7.2 Administrator Guide" page 4-46 just says "Server URL Enter the URL for your  Encryption server."
    Thanks

    Hi Jason,
    Thanks for your question.  The short answer is https://res.cisco.com:443 HOWEVER please note the following two points.  First, you will need a CRES account, so that you can download a token to use with the plugin, to authenticate to CRES; you cannot use the default token which you have probably been using with your IEA.  Second, using the current Outlook plug-in version 7.2 with CRES is not supported; it works, but it is not supported.  There are plans to release a supported version.

  • Configuring Cisco 8800 phones for VPN

    Does anyone know how to configure 8800 phones for VPN?  I am particularly interested on 8861/8851 models.
    Thanks,
    Carlos

    So I opened a TAC case and they provided me with the solution:
    "Usually you upload the Cisco_Manufacturing_CA certificate on the ASA but with the new models we should upload the Cisco_Manufacturing_CA_SHA2 creating a new trustpoint on the ASA"
    The security guide does not specify about this cert, it only mentions Cisco_Manufacturing_CA .

  • Configuring Cisco TFTP Server for CUCM

    Hi,
    I currently have a Publisher and two Subscriber (v 6.1.3), I have now gone over the magical 1250 devices where Cisco recommend a standalone TFTP server.
    I understand to deploy it I need to add it to the Publisher as a Server and then once up and running enable the Cisco TFTP service, then update the Option 150 address in my DHCP scope to point towards the new TFTP server.
    A couple of questions, does the TFTP server need the following installed at the same level as the Publisher/Subscribers:
    Dial Plans
    Device Packs
    Locales
    Thanks and any other comments appreciated.

    Hi Ian,
    - By architecture, the TFTP server would be the one pushing out the firmware load and  to the phones - so you would need your device packs, containing the bundle of firmware loads, to be on your standalone TFTP server.
    - locales install files which the phones get from the TFTP server, such as their dictionary - so you would need locales on the standalone TFTP server
    - Dial plans are files used by the CCM binary file. If you are not planning on running CCM service on the server ever, you don't need to install dial plans on that server.  However, as best practice, it is good to have dial plans, locales and device packs uploaded on this standalone TFTP server, in case the server roles were adjusted at a later point in time.

  • Configuring VLANs on Cisco switches - help on basics please!

    Hi people.
    I'm buying Cisco switches to my home lab to practice VLAN and have some doubts, would someone kindly help me?
    I'm thinking of buying two 300 series switches for the servers (VMware boxes), configure two separate VLANs for VMs and two other VLANs for desktop computers, in order to simulate a small office with a datacenter and two floors (one VLAN for each floor).
    I presume that the connection between each floor switch and the 300 series core switch will be via trunk mode on both, not access port mode, is that correct?
    Another question: for the desktop switches, the ports that are going to connect to the desktops (which runs windows with non-vlan tagging aware nic), will be configured with the correct VLAN, and the operating system will just communicate normally as if there was no VLAN tag on the frames?
    Since I need inter-vlan routing only on the core switch (the 300 series), for the desktops switches I can purchase some 200 series, right?
    And the last question: presuming that I configure a third VLAN and add a third floor switch, but this time a 100 series switch that is not VLAN capable, so connecting this switch to the 300 switch, will it work, or not?
    Thank you!

    Hi! Thanks for the rapid answers!
    I have a couple more based on the same questions:
    I presume that the connection between each floor switch and the 300 series core switch will be via trunk mode on both, not access port mode, is that correct? - Yes, trunk links are required to carry multiple vlans.
    So, I could also use multiple links with LAG/LACP carrying all vlans between switches?
    And the last question: presuming that I configure a third VLAN and add a third floor switch, but this time a 100 series switch that is not VLAN capable, so connecting this switch to the 300 switch, will it work, or not? - Yes, bit make sure that link between these two switches should be an access link, i.e must carry only third vlan.
    So, If I understand correctly, if having one vlan per floor in an office building, for economical reasons you could deploy simple non-managed and non-vlan capable switches, and in the data center, a core switch with the vlans configured for each floor?
    And viewing from a technical perspective, what would be the advantages of deploying in each floor a vlan capable switch configured with the correct vlan?
    And which method mentioned above is more common deployed for endpoint floor switches?
    Thanks!

  • Cisco SG300 Network Expansion (Configure 2 Switches)

    I’m currently in the process of expanding my network having bought a second Cisco SG300-20 which is now sitting in my lab, my current setup is described below
    Internet
    ^
    |
    Draytek Router 192.168.1.1
    ^
    |
    Cisco SG300-20 192.168.1.2

    VLAN 13 Management interface 10.0.13.1
    VLAN 14 Pubic interface 10.0.14.1
    VLAN 15 Private interface 10.0.15.1
    VLAN 20 Storage interface 10.0.20.1
    I then have a number of servers with multiple nics that run on the various VLANS attached to certain ports in the Cisco Switch
    VLAN 12 and 14 have been given access to the internet with routes added to Draytek to 10.0.12.1 / 10.0.14.1
    Now what I want to do is to expand the network running a link from my first switch to the new switch.  Ive read a number of notes on this forum but confused as to what I need to do.
    I want the new switch to have access to all the VLANS configured on the first switch and will set the ports access to the various VLANs for each server that is being connected.
    Have read that its best to have any additional switches on the network configured as Layer 2 and leave just one switch to do the routing (is that correct?).  So have left the new switch as Layer 2 and given it an IP of 192.168.1.3
    So the first question is how do I configure the uplink port from switch 1 (Port Gi2) to Switch 2 (Port Gi1).  
    Should I run multiple cables and create a LAG between the two switches?  Allowing for additional bandwidth (I stream a lot of HD movies across the network to the workstations)
    I have attached my running config from switch 1 below.
    Any help would be appreciated, unfortunately networks are not my strong point.

    prcswitch01#   

    Hi Aleksandra,
    Im still having issues with my setup.  The servers I have connected have VLAN tagging enabled
    Previously I had my esxi server connected via two nics with ports configured on my Layer 3 switch prcswitch01 as follows
    Port 1 Trunk VLAN 13-15
    Port 2  Trunk VLAN 13,20
    My NAS was configured on a single port on VLAN20
    The ESXI server can only have a single gateway which is used by both interfaces
    ~ # esxcli network ip route ipv4 list
    Network    Netmask        Gateway    Interface  Source
    default    0.0.0.0        10.0.13.1  vmk0       MANUAL
    10.0.13.0  255.255.255.0  0.0.0.0    vmk0       MANUAL
    10.0.20.0  255.255.255.0  0.0.0.0    vmk1       MANUAL
    Traffic was being passed from VLAN13 to VLAN20 to allow connectivity to the NAS on the ESXi server
    This no longer seems to be happening on my Layer 2 switch.
    I have configured the ports the same as previously setup on the Layer 3 switch.
    When I have the esxi server connected I can reach the server on 10.0.13.11 but the server cannot ping the NAS on 10.0.20.196
    Hope that makes sense, I’m confused about setting this new switch up.  Should I configure it as Layer 3 and setup interfaces for the various VLANS.  I was under the impression this would be done by my first switch.
    Thanks
    Paul

  • Question about setting vlan for Video Teleconference Equipment

    We recently purchased some Video Teleconference equipment (Product called LifeSize). Initially we had configured a seperate vlan for VTC traffic and when a user needed to move the vtc equipment to a different room for a meeting, we would have to manually go in change the vlan assignment on the switch for that port to the VTC vlan. From my understanding, there is a way to set this up so that anytime the vtc is plugged into any switch port, the port would automatically update to the proper VTC vlan. Is there a way to configure the switch to change the vlan option anytime the VTC equipment is plugged into any switchport? We are using Cisco 3750G series switches. There is an option on the VTC equipment for vlan configuration where we can specify the vlan. However, we we set the vlan, we loose connectivity to the device. If the vlan is preconfigured on the VTC equipment, what is the proper configuration on the switch port?
    Thx in advance for any help given.

    You would need a radius server to do 802.1x authentication. The radius server can associate the vlan you want to use with the authentication. So basically the device connects to the switch port, the device is challenged for credentials by the switch, it responds and then the switch passes the authentication details to the radius server. If the authentication was succesful the radius server can then pass a number of attributes back to the switch one of which is the vlan the port is to be assigned to.
    There is an additional issue with your setup in that generally 802.1x is used to authenticate clients which have an 802.1x supplicant on it but i suspect your equipment won't. So you can configure the mac authentication bypass feature. What happens here is the switch challenges your equipment but there is no response. Once the challenge has timed out you can configure the switch to then use the mac address of the connected device to authenticate it to the radius server.
    Here is the link for configuring 802.1x on the 3750 switch -
    http://www.cisco.com/en/US/docs/switches/lan/catalyst3750/software/release/12.2_55_se/configuration/guide/sw8021x.html#wp1205506
    Note the restrictions just in case they affect your setup.
    As for the radius server the Cisco version is ACS. There are others but you would need to make sure they supported everything needed.
    Final point. I have never used 802.1x to do dynamic vlan assignment so i can't guarantee anything.

  • Cisco switches and virtual ip address(load balancing address) on xenapp portals

    Hi I am quite new in configuring cisco switches and stumble across an issue after installing xenapp7.6 with load balanced portal to the ddc`s
    It seems i only can ping or get access to portal if using real ip address behind cisco switch from other subnets in my network.
    I can ping ddc01 and ddc02 and connect to the portal with http without problem. However when i triy to access the load balancing address of the ddc`s
    it wont answer to ping or http
    In same subnett it is no problem connecting to the load balancing address of the ddc`s, but in loactions on other subnets i only can access real server ip
    eks
    dd01   192.168.1.4    ok ping and access behind cisco switch from subnets
    ddc02 192.168.1.5   ok to ping  access behind cisco switch from subnets
    load balancing for both ddc 192.168.1.6 not able to get answer og access from subnets, only in same subnett
    Is there any way to configure switch to access the load balancing address of the ddc`s ?
