33 IP sFlow configuration

If you choose Custom, you may set your own sampling interval and traffic sampling rate.

-Global Settings

•Counter sampling interval - defines the interval in seconds between samples. For Ironware devices, the range is 0 to 86400. For Network OS devices, the range is 1 to 65535.

•Traffic sampling rate - the ratio between the total number of incoming packets and the number of flow samples taken at the product level. The ratio is expressed as n to 1; for example, if you specify a sampling rate of 100, the ratio is 100:1. The lower the ratio, the higher the demand on CPU resources to process the samples. For Ironware devices, the range is 1 through 1048576. For Network OS devices, the range is 2 to 16777215.

-Port Level Settings

•Apply sFlow forwarding settings - This check box is used to enable traffic sampling at the port level using the rate value specified in the sFlow forwarding sampling rate field.

•sFlow forwarding sampling rate - the ratio between the total number of incoming packets and the number of flow samples taken at the port level. The ratio is expressed as n to 1; for example, if you specify a sampling rate of 100, the ratio is 100:1. The lower the ratio, the higher the demand on CPU resources to process the samples.

•Disable sFlow forwarding - disables port level sampling.

7.Click Add to add collector details and complete the following steps.

a.Use the IP Address selector to select an IP address from the existing list of IP addresses of management server NICs, or enter a new IP address in the field. IPv4 and IPv6 addresses are allowed. IPv6 addresses are not supported for Network OS previous to v4.0 and Fabric OS previous to v7.2.

b.Enter the port number in the UDP Port field for the UDP port used to forward sFlow samples to the collector.

NOTE

VCS devices use the default port 6343. If you change the VCS device default port number, all sflow configuration are deployed to the device except the port number. The 6343 port number cannot be changed.

c.Click OK.
