Configuring the ECN330-switch
366 1553-KDU 137 365 Uen D 2006-06-16
• For IGMP Version 1, the designated router is elected according to
the multicast routing protocol that runs on the LAN. But for IGMP
Version 2, the designated querier is the lowest IP-addressed
multicast router on the subnet.
• Robustness Variable – Specifies the robustness (that is, expected
packet loss) for this interface. The robustness value is used in
calculating the appropriate range for other IGMP variables, such as the
Last Member Query Interval
(
Group Membership Interval
)
, as well as
the Other Querier Present Interval, and the Startup Query Count (RFC
2236). (Range: 1-255; Default: 2)
• Version – Configures the IGMP version used on an interface.
(Options: Version 1-2; Default: Version 2)
• All routers on the subnet must support the same version. However,
the multicast hosts on the subnet may support IGMP version 1 or 2.
• The ECN330-switch must be set to version 2 to enable the Max
Query Response Time.
• Querier – Device currently serving as the IGMP querier for this
multicast service.
