Figure 5- 5. IGMP Snooping

The table below describes the IGMP Snooping variables that can be adjusted for any single VLAN or
switch-wide to fine tune multicasting implementation on the network. This table also appears in the
next chapter.

Query Interval

The Query Interval field is used to set the time (in seconds) between transmitting
IGMP queries. Entries between 1 and 65,535 seconds are allowed. Default =
125.

Max Response Time

This determines the maximum amount of time in seconds allowed before
sending an IGMP response report. The Max Response Time field allows an entry
between 1 and 25 (seconds). Default = 10.

Robustness Variable

Adjust this variable according to expected packet loss. If packet loss on the
VLAN is expected to be high, the Robustness Variable should be increased to
accommodate increased packet loss. This entry field allows an entry of 2 to 255.
Default = 2.

Last Member Query
Interval

Specifies the maximum amount of time between group-specific query messages,
including those sent in response to leave group messages. Default = 1.

Host Timeout

This  is  the  maximum  amount of  time  in  seconds  allowed  for  a  host  to  continue
membership  in  a  multicast  group  without  the  Switch  receiving  a  host
membership report. Default = 260.

Route Timeout

This is the maximum amount of time in seconds a route is kept in the forwarding
table without receiving a membership report. Default = 260.

Leave Timer

This  specifies  the  maximum  amount  of  time  in  seconds  between  the  Switch
receiving  a  leave  group  message  from  a  host,  and  the  Switch  issuing  a  group
membership  query.  If  no  response  to  the  membership  query  is  received  before
the Leave Timer expires, the (multicast) forwarding entry for that host is deleted.

Querier State

Choose

Querier

to enable transmitting IGMP Query packets or

Non-Querier

to

disable. The default value is

Non-Querier

.

State

Select

Enabled

to implement IGMP Snooping. IGMP Snooping is

Disabled

by

default.

The diagram to the right illustrates IGMP
Snooping.  When  it  is  enabled  on  the
Switch,  only  the  branches  of  the  tree
containing  interested  hosts  (shaded)
receive the multicast stream.
