Using the Telnet Console

To configure IGMP for an IP interface

1.From the Main Menu, select Layer 3 - IP Networking Setup IGMP Interface Configurations and press Enter.

2.Configure these fields.

Field

Description

 

 

Interface Name

Specifies the name of the IP interface you want to configure. The IP address

field displays the address which corresponds to the entered IP interface.

 

 

 

Version

Specifies the version number of IGMP to be used with the IP interface. Use

the spacebar to toggle between 1 and 2.

 

 

 

Query Interval

Specifies the time (in seconds) between the transmission of IGMP query

packets. Enter a value between 1— 65535 seconds. The default is 125.

 

 

 

Max Response Time

Specifies the maximum time the switch can wait for reports from members.

Enter a value between 1— 25. The default is 10 seconds.

 

 

 

Robustness Variable

Specifies the permitted packet loss on a link. Enter a value between 1— 255.

The default is 2.

 

 

 

State

Enables or disables IGMP on this IP interface.

 

 

3. Highlight APPLY and press Enter.

Note: When IGMP is enabled on an interface, the switch IGMP snooping flag is set to Enabled and becomes a read-only parameter.

DVMRP Interface Configuration

The Distance Vector Multicast Routing Protocol (DVMRP) is a hop-based method of building multicast delivery trees from multicast sources to all nodes of a network. Because the delivery trees are “pruned” and use the “shortest path,” DVMRP is relatively efficient. Because multicast group membership information is forwarded by a distance-vector algorithm, propagation is slow. DVMRP is optimized for high delay (high latency) and relatively low-bandwidth networks, and it can be considered as a “best-effort” multicasting protocol.

To configure DVMRP for an IP interface

1.From the Main Menu, select Layer 3 - IP Networking Setup DVMRP Interface Configurations and press Enter.

2.Configure these fields.

Field

Description

 

 

Interface Name

Specifies the name of the interface to configure. This must be a previously

defined IP interface.

 

 

 

 

Specifies the maximum interval the switch will wait to hear from a neighbor.

Neighbor Timeout Interval

If this interval expires, the switch assumes that this neighbor is down. Enter

 

a value from 1— 65535. The default is 35.

 

 

 

Specifies the interval between probes. A probe is a query to other routers to

Probe Interval

determine if a multicast group is present on a given router subnetwork.

 

Enter a value from 1— 65535 seconds. The default is 10.
