Monitoring Switch Traffic

This section contains the following examples:

• Configuring sFlow
• Configuring RMON
• Configuring Remote Capture
• Configuring RSPAN

This example shows how to configure the switch so that ports 10-15 and port 

23 send sFlow datagrams to an sFlow receiver at the IP address 192.168.20.34. 

The receiver owner is receiver1, and the timeout is 100000 seconds. A counter 

sample is generated on the ports every 60 seconds (polling interval), and 1 out 

of every 8192 packets is sampled. Note that sFlow monitoring is not enabled 

until a receiver owner string is configured.
To configure the switch:

1 Configure information about the sFlow receiver.

console#configure

console(config)#sflow 1 destination 192.168.30.34

console(config)#sflow 1 destination owner 

2 Configure the polling and sampling information for Tengigabit Ethernet 

ports 10-20.

console(config)#sflow 1 polling te1/0/10-15 60

console(config)#sflow 1 sampling te1/0/10-15 8192

3 Configure the polling and sampling information for Tengigabit Ethernet 

port 23.

console(config)#interface te1/0/23

console(config-if-Te1/0/23)#sflow 1 polling 60 

console(config-if-Te1/0/23)#sflow 1 sampling 8192 

4 Verify the configured information.

console#show sflow 1 destination
