Monitoring IPv6 Hardware Multicast Packet Replication

You can use the commands explained in this topic to monitor hardware multicast packet replication-related statistics for port 8. For port 8, queue statistics have no direct relationship to any of the 8 ports because each packet that is transmitted through the queue can be sent through 1 or more of the 8 physical ports.

Multicast traffic redirected by the hardware multicast packet replication feature is displayed in the statistics for the IPv6 or VLAN interface over port 8, not the original IP or VLAN interface over the physical port.

The statistics for the IPv6 or VLAN interface over port 8 reflect the number of packets that passed through this interface destined for the hardware multicast packet replication hardware. These statistics have no direct correlation to the number of packets being transmitted from any of the physical ports.

The various statistics that are monitored over port 8 are:

Monitoring Port Statistics

Purpose

Display the status of Gigabit Ethernet interfaces. You can use the delta keyword to view baselined statistics. You can use the brief keyword to view the operational status of all configured interfaces.

Note: The E120 and E320 routers output for monitor and show commands is identical to output from other E Series routers, except that the E120 and E320 router output also includes information about the adapter identifier in the interface specifier (slot/adapter/port).
