Switching

I am new to Juniper switching. Purchased a EX2200-24P-4G. I know it is EOL, but I have to start somewhere.

I powered it up and it sees my network. I can look at the directory with my media files. When I start a client, the dlna servers do not appear. 

Anyone have a hint of where to start looking to fix this?

Thank you in advance.

Hi Robert,

Multicast flows are not enabled freely by default on Enterprise Switches. 

Here is a configuration to allow dlna (UPnP AV Spec,). This works for Chromecast to!

Also, I believe  ff0x::c (where x is the scope ID) is the IPv6 address.

protocols {
igmp-snooping {
    vlan Home {
        interface ge-0/0/2.0 {
            static {
                group 239.255.255.250;
            }
        }
        interface ge-0/0/3.0 {
            static {
                group 239.255.255.250;
            }
        }
    }
}

Yes, well, actually «The default factory configuration on legacy EX Series switches enables IGMP snooping by default on all VLANs.»

That means that on EX2200, IGMP snooping is by default on all vlans, BUT since no IGMP querier is configured, multicast flows are blocked.

Therefore one could either define statically plenty of multicast flows to flood on plenty of interfaces (as shown by Gavin), or define an IGMP querier (probably the best option), or disable IGMP snooping (which would let multicast flows be flooded everywhere like on an end-user simple switch).

protocols {igmp-snooping {    vlan Home {        interface ge-0/0/2.0 {            static {                group 239.255.255.250;            }        }        interface ge-0/0/3.0 {            static {                group 239.255.255.250;            }        }    }}
