    T1600/T2600 multicast problems

    Model :

    Hardware Version :

    Firmware Version :

    ISP : [/COLOR]

    We are Polish ISP we are using hundreds of TP-Link TL-SG3424, TL-SG2424, TL3210 switches. There was minor multicast issues but fimware upgrade solved it all.
    When we started to replace older switches to T1600/T2600 (due lack of free ports) we got multicast problems, IPTV frezes sometime for 30s - 60s. We send configs, logs, diagrams other stuff to TP-LINK and got no answer. No help at all (only "we cant find problem").
    We offered even web access......
    Now we replace T1600/T2600 to older switches or GPON.......

    Is there any chance of new firmware release/ new switches version ?
    Any other users observed multicast problems ?

    I dont uderstend why this company releases new product and cant find/solve error ?

    Sorry, but there are the same problems in our configuration with T1600-52ts. Could you please tell us your configuration for the Multicast-Source-Port and the configuration between two switches. Many thanks from Germany. You could see our scenario in the PDF nearby.

    show system-info
     Hardware Version     - T2600G-52TS 1.0
     Software Version     - 1.0.1 Build 20160412 Rel.52062(s)
    In global config port 49 is UPLINK:
    ip igmp snooping vlan-config 211      
    ip igmp snooping vlan-config 211 rport interface gigabitEthernet 1/0/49
    and for access ports something like:
    interface gigabitEthernet 1/0/34      
      switchport access vlan 211          
      storm-control pps                   
      storm-control broadcast pps 1024    
      storm-control multicast pps 1024    
      port isolation gi-forward-list 1/0/49
      ip igmp snooping                    
      access-list bind acl 1500           
      loopback-detection config process-mode port-based recovery-mode auto
    Above configuration works when uplink switch for TPLINK is DLINK DGS-3120. We have issue when we try replace DLINK with DCN.
