The switch provides a local registry of active multicast groups for each IP interface, including the age and expiration time for each entry.
Parameter | Description |
Group Address | An IP multicast group address with subscribers directly attached or downstream from |
| this switch. |
Interface | The IP interface on this switch that has received traffic directed to the IP multicast |
| group address. (See 5.8.6.1 Displaying Subnet Information.) |
Reporter | The IP address of the source of the last membership report received for this IP |
| Multicast group address on this interface. If no membership report has been received, |
| this object has the value 0.0.0.0. |
Up Time | The time elapsed since this entry was created. |
Expire Time | The time remaining before this entry will be aged out. (The default is 260 seconds.) |
V1 Timer | The time remaining until the switch assumes that there are no longer any IGMP |
| Version 1 members on the IP subnet attached to this interface. (The default is 400 |
| seconds.) |
| If the switch receives an IGMP Version 1 Membership Report, it sets a timer to note |
| that there are Version 1 hosts present which are members of the group for which it |
| heard the report. |
| If there are Version 1 hosts present for a particular group, the switch will ignore any |
| Leave Group messages that it receives for that group. |
