Displaying RMON Statistics for Specific Ports
Display individual RMON statistics for specific ports to manage network performance.

Note
Slot and port information can differ depending on hardware platform.
Procedure
Example
View RMON statistics:

Variable Definitions
Use the data in the following table to use the show interfaces GigabitEthernet statistics rmon command.
Variable |
Value |
---|---|
{slot/port[/sub-port][-slot/port[/sub-port]][,...]} |
Identifies the slot and port in one of the following formats: a single slot and port (slot/port), a range of slots and ports (slot/port-slot/port), or a series of slots and ports (slot/port,slot/port,slot/port). If the platform supports channelization and the port is channelized, you must also specify the sub-port in the format slot/port/sub-port. |
Job Aid
The following table describes parameters for the show interfaces GigabitEthernet statistics rmon command output.
Parameter |
Description |
---|---|
PORT NUM |
Indicates the port number. |
OCTETS |
The total number of octets of data (including those in bad packets) received on the network (excluding framing bits but including FCS octets). |
PKTS |
The total number of packets (including bad packets, broadcast packets, and multicast packets) received. |
MULTICAST |
The total number of packets received that were directed to a multicast address. This number does not include packets directed to the broadcast address. |
BROADCAST |
The total number of packets received that were directed to the broadcast address. This number does not include multicast packets. |
CRC ALLIGN |
The total number of packets received that had a length (excluding framing bits, but including FCS octets) between 64 and 1518 octets, inclusive, but had either a bad Frame Check Sequence (FCS) with an integral number of octets (FCS Error), or a bad FCS with a nonintegral number of octets (Alignment Error). |
UNDERSIZE |
The total number of packets received that were less than 64 octets long (excluding framing bits, but including FCS octets) and were otherwise well formed. |
OVERSIZE |
The total number of packets received that were longer than 1518 octets (excluding framing bits, but including FCS octets) and were otherwise well formed. |
FRAGMENT |
The total number of packets received that were less than 64 octets in length (excluding framing bits but including FCS octets) and had either a bad Frame Check Sequence (FCS) with an integral number of octets (FCS Error) or a bad FCS with a nonintegral number of octets (Alignment Error). |
COLLISION |
An estimated value for the total number of collisions on this Ethernet segment. |
