To enable sFlow sampling:
1. Set the IP address of a receiver (also known as a collector or server) for sFlow statistics. Use
the sFlow Receiver Settings page for this.
2. Enable flow and/or counter sampling, direct the samples to a receiving index, and configure
the average sampling rate. Use the sFlow Interface Settings pages for this.
3. View and clear the sFlow statistics counters. Use the sFlow Statistics page for this.
sFlow Receiver Settings
To set the sFlow receiver parameters:
STEP 1 Click Status and Statistics > sFlow > sFlow Receivers.
STEP 2 Enter the following fields:
• IPv4 Source Interface— Select the IPv4 source interface.
NOTE If the Auto option is selected, the system takes the source IP address from the IP
address defined on the outgoing interface.
• IPv6 Source Interface— Select the IPv6 source interface
STEP 3 To add a receiver (sFlow analyzer), click Add and select one of the pre-defined sampling
definition indices in Receiver Index.
STEP 4 Enter the receiver’s address fields:
• Receiver Definition—Select whether to specify the sFlow server By IP address or By
name.
If Receiver Definition is By IP Address:
• IP Version—Select whether an IPv4 or an IPv6 address for the server is used.
• IPv6 Address Type—Select the IPv6 address type (if IPv6 is used). The options are:
- Link Local—The IPv6 address uniquely identifies hosts on a single network link.
A link local address has a prefix of FE80, is not routable, and can be used for
communication only on the local network. Only one link local address is supported.
If a link local address exists on the interface, this entry replaces the address in the
configuration.
- Global—The IPv6 address is a global Unicast IPV6 type that is visible and
reachable from other networks.
