И снова в почте тишина. Ладно, это становится хорошей традицией выкладывать копию письма тут.
Имеем схему:
источник --- Cisco3550 --- (2:11)DES6500(8:9) --- PC
конфиг Cisco3550:
# sh ru
!
interface Vlan100
ip address 10.206.231.202 255.255.254.0
ip pim sparse-mode
!
# sh ip igmp interface vlan 100
Vlan100 is up, line protocol is down
Internet address is 10.206.231.202/23
IGMP is enabled on interface
Current IGMP host version is 2
Current IGMP router version is 2
IGMP query interval is 60 seconds
IGMP querier timeout is 120 seconds
IGMP max query response time is 10 seconds
Last member query count is 2
Last member query response interval is 1000 ms
Inbound IGMP access group is not set
IGMP activity: 1072 joins, 1072 leaves
Multicast routing is enabled on interface
Multicast TTL threshold is 0
Multicast designated router (DR) is 0.0.0.0
IGMP querying router is 10.206.231.202 (this system)
No multicast groups joined by this system
конфиг DES6500 касающийся 100-го влана
create vlan satellite tag 100 type 1q_vlan
config vlan satellite add untagged 2:11
config vlan satellite add untagged 8:9
config igmp_snooping satellite host_timeout 260 router_timeout 260 leave_timer 2 state enabled
config igmp_snooping querier satellite query_interval 125 max_response_time 10 robustness_variable 2 last_member_query_interval 1 state disabled
Мультикаст в такой конфигурации через свич(6500) не проходит(загрузка процессора вырастает до 30%).
Мультикаст в аналогичной конфигурации с "config igmp_snooping querier satellite query_interval 125 max_response_time 10 robustness_variable 2 last_member_query_interval 1 state enable" через свич(6500) не проходит(загрузка процессора нормальная).
Если подключить клиент напрямую в cisco3550 все работает.
Если заменить 6500 на к примеру 3526 с аналогичными настройками все работает.
Если отключить igmp_snooping на 6500 трафик начинает идти(загрузка процессора вырастает до 30%).
Хотелось бы чтобы трафик ходил при включенном igmp_snooping.
