Usage
Information
The show sflow command displays the configured global extended information.
FTOS 7.8.1.0 and later enhances the sFlow implementation for real time traffic analysis on
the E-Series to provide extended gateway information in cases where the destination IP
addresses are learned by different routing protocols and for cases where the destination is
reachable over ECMP.
Example
FTOS#show sflow
sFlow services are enabled
Global default sampling rate: 64
Global default counter polling interval: 1000
Global extended information enabled: gateway, router, switch
1 collectors configured
Collector IP addr: 20.20.20.2, Agent IP addr: 10.11.201.7, UDP port: 6343
1732336 UDP packets exported
0 UDP packets dropped
12510225 sFlow samples collected
0 sFlow samples dropped due to sub-sampling

Note: After a physical port is a member of a LAG, it inherits the sFlow configuration
from the LAG port.
