Yönetilebilir ya da Yönetilemez Switch: Yönetilebilirlik açısından PoE anahtarı arasındaki temel farklar, işlevsellik, yapılandırılabilme ve tabii ki fiyat temellidir. Yönetilebilir PoE switch modelleri ise ağ protokollerini VLAN, IGMP Snooping veya daha fazlası gibi özellikler olarak yapılandırmanıza izin verirler.

Jul 01, 2014 · However, IGMP snooping lacks the support for user roaming when IP mobility is on. If a user roams to a new VLAN with an old IP address, the upper layer does not to send out a new IGMP join and services are disrupted. IGMP proxy: The controller joins multicast group(s) on behalf of mobile clients. This action reduces the number of IGMP messages ...
As we have seen in the IGMP snooping lesson, switches will listen to IGMP messages and learn on which interfaces they have to forward multicast traffic. Without IGMP snooping, switches will flood multicast traffic everywhere, treating it like broadcast traffic. IGMP snooping works pretty well but it does require a multicast router in the network. When you want to implement it in a simple network, where you only have one VLAN and multiple switches, you can run into two possible issues:
All phones are on the same subnet, and IGMP Snooping is on I believe. Allworx version is 18.104.22.168. Campus wide we have about 90 phones. On the paging zones in question, it probably goes to about 30ish phones. TCE Company didn't mention that as seeming like a problem. And it worked before we put in all Unifi switches.
IGMP snooping is the process of listening to Internet Group Management Protocol (IGMP) network traffic to control delivery of IP multicasts. Network switches with IGMP snooping listen in on the IGMP conversation between hosts and routers and maintain a map of which links need which IP multicast transmission.
As far as I know, IGMP and IGMP snooping are two different features. IGMP (v1 or v2 or v3) is a L3 protocol, and IGMP snooping is a feature that works at L2 and for switches that are not L3 necessarily. Checking the "Aruba 2930F / 2930M Multicast and Routing Guide for ArubaOS-Switch...
