Configuring IGMP on a brouter port
To configure IGMP parameters on a brouter port:
|
|
From the Device Manager menu bar, choose Edit > Port > IGMP. |
| The Port dialog box opens with the IGMP tab displayed. |
The table below describes the items on the IGMP tab.
|
QueryInterval
|
The frequency (in seconds) at which IGMP host query packets are transmitted on the interface. The range is 1 to 65535 with a default of 125.
|
Version
|
The version (version1 or version2) of IGMP that is running on the interface. For IGMP to function correctly, all routers on a LAN must be configured to run the same version of IGMP on that LAN. The default is version 2.
|
QueryMaxResponseTime
|
The maximum response time (in seconds) advertised in IGMPv2 queries on the interface. Smaller values allow a router to prune groups faster. The range is 1 to 255 with a default of 10 seconds.
|
Robustness
|
This parameter allows tuning for the expected packet loss of a network. This value is equal to the number of expected query packet losses per serial query interval, plus 1. If a network is expected to lose query packets, the robustness value should be increased. The range is from 2 to 255 with a default value of 2. The default value of 2 means that one query per query interval may be dropped without the querier aging out.
|
LastMembQueryIntvl
|
Increasing this parameter increases the time before aging hosts on the network. It also increases the number of retransmits of group-specific queries. The range is from 1 to 255. The default value is 1.
|
SnoopEnable
|
Enables snoop.
|
ProxySnoopEnable
|
Enables proxy snoop.
|
FastLeaveEnable
|
Enables fast leave on the interface.
