IGMP Cache Table

The IGMP Cache Table contains information for each IP Multicast group whose members are part of an interface on a physical port.

The Cache Table displays the following fields :

• Cache Address — Specifies the IP Multicast Group address to which the port is a member.

• IfIndex — Indicates the VLAN or port number.

• Cache Self — Indicates if the local system is a member of an IP Multicast group. If the entry is learned from a VLAN, the field value is specified by the physical port, and if not the field entry is 0.

• Last Reporter — Identifies the last member to join the IP Multicast group by the IP address. If no member has entered the IP Multicast group the value is 0.0.0.0.

• UpTime — Indicates in ticks the amount of time that has passed since the entry was created.

• Expiry Time — Indicates the amount of time in ticks before the entry is aged out.

• Status — Indicates the status of the entry. The possible values are:

• Active

• Destructed

• Version1 Host Timer — Indicates the amount of time before the router assumes that there are no longer IGMP members on a subnet. If no IGMP group members are reported the Version1 Host timer is reset.
