Use the show vlan subinterface command to display statistics for a VLAN interface configured over port 8. For more information, see Monitoring Ethernet Interfaces in the JUNOSe Physical Layer Configuration Guide.
Use the show ip interface command to display statistics for an IP interface configured over port 8. For more information, see Monitoring IP in the JUNOSe IP, IPv6, and IGP Configuration Guide.
Multicast traffic redirected by the hardware multicast packet replication feature is displayed in the statistics for the IP or VLAN interface over port 8, not the original IP or VLAN interface over the physical port.
The statistics for the IP 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.
