sFlow Agent
Configuring sFlow Using the Web Browser Interface
■ sFlow MIB Version—the agent’s MIB version. The MIB specifies how the
agent extracts and bundles sampled data, and the sFlow receiver must
support the agent’s MIB. The Wireless Edge Services zl Module’s MIB
version is 1.3, so your sFlow collector’s version must also be at least 1.3.
■ Organization—HP. The sFlow receiver must also know the organization to
identify the implementation of sFlow on this agent.
■ Revision—the Wireless Edge Services zl Module’s current software image.
■ Address Type—the protocol version for IP addresses.
■ Address—the Wireless Edge Services zl Module’s management IP address.
You should always configure a static address on the management interface
when implementing sFlow.
If your sFlow receiver cannot configure the Wireless Edge Services zl Module’s
sFlow agent, you must configure sFlow manually. Complete the following
tasks to configure the Wireless Edge Services zl Module to act as an sFlow
agent:
1. Configure up to three sFlow receiver instances through the Web browser
interface.
From the CLI, you can configure three more sFlow receiver instances.
2. Configure flow sampling instances for RP radios:
a. To control where the agent sends this radio’s samples, match the flow
sampling instances to receiver instances.
b. Specify how frequently radios sample packets.
3. Configure counter polling instances for RP radios:
a. To control where the agent sends this radio’s counters, match the
counter polling instances to receiver instances.
b. Specify how frequently radios are polled for the counters.
Manually Configuring sFlow Receiver Instances Using
the Web Browser Interface
The Wireless Edge Services zl Module can forward sFlow datagrams to up to
six sFlow receivers. For example, it could report to a PCM Plus server, to an
Intrusion Detection System/Intrusion Prevention System (IDS/IPS), and to a
server running a billing application.
Each receiver has its own receiver instance. Many receivers can configure the
instance automatically. If you decide to configure instances manually, you can
configure three receiver instances (1, 2, and 3) only through the CLI. (See
