Field

Description

 

 

 

 

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.”
