Configuring RMON Ethernet group statistics collection

You can collect RMON Ethernet group statistics on an interface. RMON alarms and events must be configured for you to display collection statistics. By default, RMON Ethernet group statistics are not enabled.

Ethernet group statistics collection is not supported on ISL links.

To collect RMON Ethernet group statistics on an interface, perform the following steps from privileged EXEC mode.

Enter the configure terminal command to access global configuration mode.
```
device# configure terminal
```
Enter the interface command to specify the interface type and slot/port number.
```
device(config)# interface ethernet 0/1 
```

Configure RMON Ethernet group statistics on the interface.

device(conf-if-eth-0/1)# rmon collection stats 200 owner john_smith

Return to privileged EXEC mode.
```
device(conf-if-eth-0/1)# end
```
Enter the copy command to save the running-config file to the startup-config file.
```
device# copy running-config startup-config
```
