IGMP network: Wireshark shows lot of ARP request from TVs
« on: April 26, 2018, 05:17:24 AM »
Hi Everyone,
We have an IPTV network running all over the network and when we capture wireshark packets in IPTV VLAN, we could see each TVs sending ARP request saying "Who has 10.20.20.20?" in every 60 seconds. Here 10.20.20.20 is IPTV server and we also found that soon after the IPTV server got this APR message, it replies to the TVs promptly. But what my question is, even though IPTV server (10.10.20.20) replying the ARP request, why TVs are sending the same ARP request exactly at each 60 seconds?

Awaiting for the prompt suggestion and thanks in advance

Regards
Mohamed

Hi Mohamed,

It sounds like the ARP cache is cleared every 60 seconds?

Hi Flintstone,
Do you mean tha ARP cache of TVs?
All of a sudden what may be the reason for this cause without doing any chnages or upgrades?

Hi Mohamed,

It sounds like everything is working OK?  It sounds like the software of the TVs has been designed to work this way?

Hi All,
Yes. Issue resolved. Everything is fine.
We found some bugs with IPTV server and also TV is designed to broadcast that request by itself

Thank you all again
