Packet counter samples
A polling interval defines how often the sFlow octet and packet counter for a specific interface are sent
to the sFlow collector, but the sFlow agent is free to schedule the polling in order to maximize internal
efficiency.
Hardware support matrix for sFlow
The following table identifies Brocade VDX 8770 and VDX 67xx device support for specific sFlow
features.
