I choose to buy a SRW224G4P with this documentation:
On this documentation, the switch is able to use IGMP v3 and IGMP querier:
p99: IGMP Version
Sets the protocol version for compatibility with other devices on the network. All systems on the subnet must support the same version. Also note that some attributes are only enabled for IGMPv2 and/or v3, including Act as IGMP Querier, IGMP Report Delay and IGMP Query Timeout. (Range: 1-3; Default: 2)
The switch that I receive is note able to do this.
The version of the firmware describe in this documentation is:
p32: Firmware Version 1.2.4 Aug 27 2008
And my switch has the version 1.0.2 which is the only available on the Cisco website at
Where can I find this new firmware?
I bought this switch for a VOD network, and I really need this features.
Thanks for your help
