Configuring for Network Management Applications
Using SNMP Tools To Manage the Switch
Note the following details:
â– Destination Address remains blank unless it has been configured.
â– Datagrams Sent shows the number of datagrams sent by the switch
agent to the management station since the switch agent was last
enabled.
â– Timeout displays the number of seconds remaining before the switch
agent will automatically disable sFlow (this is set by the management
station and decrements with time).
â– Max Datagram Size shows the currently set value (typically a
default value, but this can also be set by the management station).
The show sflow <instance> sampling-polling [port-list] command displays infor-
mation about sFlow sampling and polling on the switch. You can specify a list
or range of ports for which to view sampling information.

Figure 13-13. Example of Viewing sFlow Sampling and Polling Information
Note The sampling and polling instances (noted in parentheses) coupled to a
specific receiver instance are assigned dynamically, and so the instance
numbers may not always match. The key thing to note is whether sampling or
polling is enabled on a port, and the sampling rates or polling intervals for the
receiver instance configured on each port.
