IPTV freezing

[AbdulFathah]

Hi,

I have a client for IPTV requirement using HP 2020 switch to connect STB's.

Same switch is connected to IPTV Server(Streams). We have configured ports with igmp .

Switch is acting as layer 2. We have configured PC for testing using 192.168.1.100 which is IPTV subnet/24.

Issue is video and audio is freezing. But when we connect through small 4 port access switch video is working fine.

Can you please help ? We only have one HP 2020 switch which is connected to IPTV server and client ?

Please change HP 2020 to HP 2620

We tried below but no luck. Software ver is 15.5

Type "vlan 1 ip igmp" to enable IGMP Snooping on the default VLAN 1 of the switch. Repeat the command, replacing "1" with another VLAN number, for each VLAN configured on the switch that must support multicast traffic.

Type "vlan 1 ip igmp querier" to enable IGMP Querier on the default VLAN 1 of the switch. Only enable IGMP Querier if the switch is not connected to a router or switch that has multicast routing enabled. Repeat the command, replacing "1" with another VLAN number, for each VLAN configured on the switch that must support multicast traffic and is not connected to a router or switch with multicast routing enabled

Kindly any one update please

I think querier is actually on by default, so what you need to do is go to every network switch where that VLAN is present and disable querier, except for the core or distribution switch where you want it to happen.

Also, do you monitor your network switchports utilisation? Can you see congested links? Can you see high latency links? These are the links where you do not want your multicast streams traversing.

Thanks. After i enable ip igmp IPTV works fine.

Now i have another problem. In the data center HP 2620 switch, i have Avaya Server,IPTV Server, Internet Modem connected.

In HP 2620, i have created two VLAN- default for voice and internet and vlan 2 for IPTV.

IPTV is working  only when STB is connected directly. But i have another switch connected through fiber link and connected to another hp 2620 48 port switch where IPTV not working.

WHen i tried to change port 52 to trunk, IPTV started working but Internet and phone stopped

hostname "HP-E2620-24-PoEP"

"Trunk" has nothing to do with VLANs (that's Cisco).

Instead, what you need is to do is:

delete trk1

vlan 2 tag 28

Thanks Brother.

Let me clear before i got to site.

My configurations are fine ?  I just want to extent Voice, Internet and IPTV to all other locations

Should i want to use same command in all other sites ? I have 3 sites using hp2620 24 port where IPTV,Phones,internet are connected ?

In both vlan i will tagg port 26 and i will check

[AbdulFathah]

tagged 52 and it works fine when port 52 is connected to another Hp 2620.

But all other HP 2620 is connected via HP E5400 zl Switch Series modular switches. Where port 52 is connected.

ANy configuration required in HP E5400 zl Switch Series ? show i tagg there as well ?

It has onlt RS232 console port. Anyother way to access this HP E5400 zl Switch Series ?

[Vince-Whirlwind]

You should be able to telnet or ssh to the 5400.

You need to configure the port on the 5400 the same as the port it is connected to on the 2600: same VLAN untagged (if any) and same VLANs tagged.
