sFlow
A
NOTE
When you enable sFlow forwarding on a trunk port, only the primary port of the trunk group forwards
sFlow samples.
To enable sFlow forwarding on a trunk port, enter commands such as the following.
PowerConnect(config)#sflow enable
PowerConnect(config)#trunk e 4/1 to 4/8
PowerConnect(config-trunk-4/1-4/8)#config-trunk-ind
PowerConnect(config-trunk-4/1-4/8)#sflow forwarding e 4/2
These commands globally enable sFlow, then enable sFlow forwarding on trunk port e 4/2. You
must use both the sflow enable and sflow forwarding commands to enable the feature.
Syntax: [no] sflow enable
Syntax: [no] sflow forwarding
Configuring sFlow version 5 features
NOTE
The commands in this section are supported when sFlow version 5 is enabled on the device. These
commands are not supported with sFlow version 2. sFlow version 5 also supports all of the sFlow
configuration commands in “Configuring and enabling sFlow” on page 1430.
When sFlow version 5 is enabled on the device, you can do the following:
Specify the sFlow version (version 2 or version 5)
Specify the sFlow agent IP address
Specify the maximum flow sample size
Export CPU and memory usage Information to the sFlow collector
Specify the polling interval for exporting CPU and memory usage information to the sFlow
collector
Export CPU-directed data (management traffic) to the sFlow collector
Egress interface ID for sampled broadcast and multicast packets
For broadcast and multicast traffic, the egress interface ID for sampled traffic is always
0x80000000. When broadcast and multicast packets are sampled, they are usually forwarded to
more than one port. However, the output port field in an sFlow datagram supports the display of
one egress interface ID only. Therefore, the sFlow version 5 agent always sets the output port ID to
0x80000000 for broadcast and multicast packets that are sampled.
Specifying the sFlow version format
If your device supports sFlow version 5, you can optionally specify the version used for exporting
sFlow data. Refer “Specifying the sFlow agent IP address”.
