Hi i need help configure a cisco switch WS-C3750G to allow one application to send multicast packet inter-vlan

Presently the software im using is set to "IP - Multicast" to transmit data.  I only see clients that are on the same vlan as me

What i would like to do is allow only my workstation that is on vlan 10 (192.168.10.xx) to use multicast to find clients in vlan 80 (192.168.80.xx)

Can someone help me do this please im not really sure what to do....ive read this document (http://www.cisco.com/en/US/products/hw/switches/ps5023/products_configuration_example09186a008076c6e0.shtml) but im not sure if it's ok

Thanks for your help !

It sounds more like you wanna configure multicast routing in your 3750. Have a look at the following link instead:

http://www.cisco.com/en/US/docs/switches/lan/catalyst3750/software/release/12.2_25_sed/configuration/guide/swmcast.html#wp1099221

Try this:

configure terminal
  interface vlan10
    ip pim sparse-dense-mode
  interface vlan80
    ip pim sparse-dense-mode
end

Open in new window

Also try to add this first:

      

HV_CORE_1(config)# ip multicast-routing distributed 

Open in new window


or

HV_CORE_1(config)# ip multicast-routing

Open in new window


Then add the ip pim commands above

What Is Threat Intelligence?

Threat intelligence is often discussed, but rarely understood. Starting with a precise definition, along with clear business goals, is essential.

Ah, you are running IP Base:

From Cisco:

To use the IP multicast routing features, the stack master must be running the IP services image (formerly known as the enhanced multilayer image [EMI]).

Only the switches with the "interface Vlans" that need the ip pim commands (the ones doing the routing), presumably just this one. The 'switching' switches can be left alone.
