Viewing sFlow Configuration and Status (CLI)
The following sFlow commands allow you to display sFlow configuration and status through the CLI
Viewing sFlow destination information is an example of
sflow agent information.
Syntax:
show sflow agent
Displays sFlow agent information. The agent address is normally the IP address of the first VLAN configured.
The
show sflow agent command displays read-only switch agent information. The version information shows the sFlow version, MIB support, and software versions; the agent address is typically the IP address of the first VLAN configured on the switch.
Viewing sflow agent information
switch# show sflow agent Version 1.3;XX.11.40 Agent Address 10.0.10.228
Syntax:
show sflow <receiver instance> destination
Displays information about the management station to which the sFlow sampling-polling data is sent.
The
show sflow
instance destination
command includes information about the management-station's destination address, receiver port, and owner, as shown in the following example.
Viewing sFlow destination information
switch# show sflow 2 destination Destination Instance 2 sflow Enabled Datagrams Sent 221 Destination Address 10.0.10.41 Receiver Port 6343 Owner Administrator, CLI-owned, Instance 2 Timeout (seconds) 99995530 Max Datagram Size 1400 Datagram Version Support 5
- Destination Address remains blank unless it has been configured.
- Datagrams Sent shows the number of datagrams sent by the switch agent to the management station since the switch agent was last enabled.
- 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).
- Max Datagram Size shows the currently set value (typically a default value, but this can also be set by the management station).
Syntax:
show sflow <receiver instance> sampling-polling <port-list/range>
Displays status information about sFlow sampling and polling.
The
show sflow
instance sampling-polling [port-list]
command displays information about sFlow sampling and polling on the switch, as shown in the following example. You can specify a list or range of ports for which to view sampling information.
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.
