Diagnosing Switch Problems sFlow
OmniSwitch 6800/6850/9000 Network Configuration Guide March 2008 page 35-31
To configure a sFlow poller session, use the sflow poller command by entering sflow poller, followed by
the instance ID number, the slot number of the port to be monitored, a slash (/), and the port number of the
port and receiver, the receiver_index.
For example, to configure poller session 3 on port 1/1, enter:
-> sflow poller 3 1/1 receiver 6
In addition, you can also specify optional parameters shown in the table below. These parameters can be
entered after the receiver index.
For example, to configure sFlow poller session 3 on port 1/1 and specifies the interval, enter:
-> sflow poller 3 1/1 receiver 6 interval 5
Configuring a Fixed Primary Address
It is necessary to execute the ip interface command to make a loopback0 IP address as the fixed primary
address of the switch, in order to avoid interface changes, which might need the collector software to be
restarted for it to communicate using the new agent IP address. Normally, the primary IP address could
change depending on the IP interface going up/down. Therefore, the sFlow agent always needs to send a
fixed IP address in the datagram.
For example, to configure the loopback0 address as a primary IP address, enter:
-> ip interface loopback0 address 198.206.181.100
Note. The loopback address should be an IP interface configured on the switch.
Displaying a sFlow Receiver
The show sflow receiver command is used to display the receiver table.
For example, to view the sFlow receiver table, enter the show sflow receiver command without specify-
ing any additional parameters. A screen similar to the following example will be displayed, as shown
below:
-> show sflow receiver
Receiver 1
Name = Golden
Address = IP_V4 198.206.181.3
UDP Port = 6343
Timeout = 65535
Packet Size= 1400
DatagramVer= 5
Note. For more information about the displays that result from these commands, see the OmniSwitch CLI
Reference Guide.
