Table 77: sFlow Sampler Configuration Fields (continued)
Field
Description
Egress
Sampling Rate
sFlow instance egress packet Sampling Rate.
Flow-based
Sampling Rate
sFlow instance flow based packet Sampling Rate.
Maximum
Header Size
The maximum number of bytes that should be copied from a sampled packet. The allowed
range is 20 to 256.
sFlow Source Interface Configuration
Use the sFlow Source Interface Configuration page to specify the physical or logical interface to use as
the sFlow client source interface. When an IP address is configured on the source interface, this address
is used for all sFlow communications between the local sFlow client and the remote sFlow server. The IP
address of the designated source interface is used in the IP header of sFlow management protocol
packets. This allows security devices, such as firewalls, to identify all source packets coming from a
specific device.

Table 78: sFlow Source Interface Configuration Fields
Field
Description
Type
The type of interface to use as the source interface:
•
None – The primary IP address of the originating (outbound) interface is used as the source
address.
•
Interface – The primary IP address of a physical port is used as the source address.
•
Loopback – The primary IP address of the loopback interface is used as the source address.
A loopback is always reachable, as long as any routing interface is up.
•
VLAN – The primary IP address of a VLAN routing interface is used as the source address.
Interface
When the selected Type is Interface, select the physical port to use as the source interface.
Loopback
Interface
When the selected Type is Loopback, select the loopback interface to use as the source
interface.
VLAN ID
When the selected Type is VLAN, select the VLAN to use as the source interface. The menu
contains only the VLAN IDs for VLAN routing interfaces.
Tunnel ID
The primary IP address of a tunnel interface is used as the source address.
If you change any of the parameters, click

to apply the changes to the system. If you want the
switch to retain the new values across a power cycle, you must save the configuration.
