sFlow event workflow

Configuring steps
4. Enable sFlow.
5. Enable null0 sampling.
6. Configure null0 routes.
NOTE
Above commands can be performed in any order.
Feature characteristics
IPv4, IPv4-VPN, IPv6 null0 routes can be sFlow sampled.
Only explicitly configured null0 routes can be sFlow sampled. Implicit null0 drops cannot be
sFlow sampled.
By default, null0 sFlow sampling feature is disabled.
Limitations
When this feature is enabled, due to sampling of more packets (discarded packets) than the
usual number till now, the actual sampling rate for regular streams will be reduced.
This feature does not support PBR related null0 drops.
This feature does not support default null0 route drops.
Backward compatibility
The current sFlow functionalities and ACL based sFlow functionalities will co-exist with this feature.
As the dropped packets hit TM, if mirroring is enabled on that port, these dropped packets will also
get mirrored.
Enabling/disabling the null0 sFlow sampling
These commands include the enabling and disabling of the null0 sampling.
Enter the following command to enable sFlow sampling for null0 routes.
Brocade(config)#sflow null0-sampling
To disable null0 sampling, enter the following command.
Brocade(config)#no sflow null0-sampling
Syntax: [no] sflow null0-sampling
Configuring a null0 route
For configuring a route for null0 sampling, use the following command.
Brocade(config)#ip route 10.10.10.100/32 null0
Syntax: [no] [ip|ipv6] route ip-addr null0
