Sender tab
The Sender tab (Figure 61) displays information about the IGMP Snoop sender
device.
Expiration Time left until this member is aged out. This value is
derived from the Robust Value, MaxResponse Time value,
and Query Interval. The Query Max Response Interval
(obtained from the Queries received) is used as the timer
resolution. Increasing the Robust Value also increases the
expiration value.
Type Static or dynamic:
• Static membership is configured by the user using the
Multicast Static window.
• Dynamic membership is what the switch learned from
receiving group reports.
An entry can change from static to dynamic if the switch
learns of a membership dynamically through a static port.
In this case, the entry is not deleted when the expiration
value goes to zero; instead, its type goes back to “static.”
