Statistics (RMON group 1)

The following statistics are collected for each port on a RUCKUS Layer 2 Switch or Layer 3 Switch: multicast and broadcast packet counts; number of total packets sent; undersized and oversized packet counts; numbers of CRC alignment errors, jabbers, collisions, fragments, and dropped events.

The statistics group collects statistics on promiscuous traffic across an interface. The interface group collects statistics on total traffic into and out of the agent interface.

No configuration is required to activate collection of statistics for the Layer 2 Switch or Layer 3 Switch. This activity is by default automatically activated at system start-up.

Use the show rmon statistics command to view a textual summary of the statistics for all ports, as shown in the following example.

   128 to 255 octets pkts          0    256 to 511 octets pkts          0
  512 to 1023 octets pkts          0  1024 to 1518 octets pkts          0

The SNMP numbers of the ports start at 1 and increase sequentially. For example, if you are using a Chassis device and slot 1 contains an 8-port module, the SNMP number of the first port in slot 2 is 9. The physical port number of the same port is 1/2/1.
