Hello,
i’m trying multicast with fog 1.5.5 and alcatel switchs (OS6250 and OS6450).
When i launch a multicast session it’s extremely slow.
For the configuration of the switchs i made like this :
On all switchs enable igmp globaly and on vlan 2 (fog server)
ip multicast status enable
ip multicast vlan 2 status enable
ip multicast zapping enable
ip multicast vlan 2 zapping enable
ip multicast version 3
ip multicast vlan 2 version 3
ip multicast querier-forwarding enable
ip multicast vlan 2 querier-forwarding enable
On the querier switch (the closest to the fog server)
ip multicast querying enable
ip multicast vlan 2 querying enable
ip interface Querier address 192.168.39.244 mask 255.255.255.0 vlan 2
Disable igmp on all other vlans on all the switchs
All computers are on 100M port and the fog server on 1G port
You can see on this diagram http://plegrand1.free.fr/IGMP.png (old diagram )
not a ghost server but a fog server
I add global statement
The server is on a 1G port
the flow is very fast at the beginning then goes down to be very slow (25M / min)
Here is the server characteristics
PowerEdge T310
Intel(R) Xeon(R) CPU X3480 @ 3.07GHz
cores = 4
enabledcores = 4
threads = 8
Ram = 32GiB
Ethernet interface
NetXtreme II BCM5716 Gigabit Ethernet
eth0
1Gbit/s
Could you help me to solve this problem ?
