На коммутаторах D-Link DES3028G заметил что при выводе команды show igmp_snooping group очень большой список групп. Оказалось после отключения абонента от группы, эта группа не изчезает из списка, а остаётся в нём. На коммутаторах DES3526 всё нормально.


Эти группы не исчезают через какое-то время, а висят до ввода команды clear igmp_snooping data_driven_group all или ребута свитча. Когда их больше 100 вывод команды show igmp_snooping group становиться мягко говоря не читаемым. Нормальное ли это поведение?
Проверял на прошивках 2.00-B27 и 2.41-B03.

Не нормально. Так как на 3028 начинаются коллизии с клиентскими маками даже при влане на коммутатор, так как иногда клиенты тоже умудряются накакать в эту таблицу.
Вот это накакал какой то клиент. И спрашивается как от этого защититься

To Ivantey:

Вы не могли бы завтра перезвонить мне на 8(962)944-46-12.

А мне в данной ситуации что делать?

2 WinsDark> Введите команду:
config igmp_snooping data_driven_learning vlan_name tv aged_out enable
