Configuring the sFlow Collector
You must configure sFlow Collector before configuring the sFlow Agents. The sFlow Collector receives sFlow Datagrams or packets from the sFlow Agents.
To configure an sFlow Collector’s IP address and port, use the command:
CLI (network-admin@switch) > sflow-collector-create collector-ip ip-address collector-port collector-port-number name name-string scope local|fabric
|
collector-ip ip-address |
Specify the IP address of the sFlow Collector. |
|
collector-port collector-port-number |
Specify the port number assigned to the sFlow Collector. |
|
name name-string |
Specify a name for the sFlow. |
|
scope local|fabric |
Specify if the scope is local or fabric. Note: If the scope is fabric, then the new switches that join the fabric receive the sFlow Collector configuration. If the scope is local, then the sFlow Collector is configured only on the local switch. |
Below is an example configuration of an sFlow Collector with IP address 10.10.10.12, on port 2055. The Collector name is sf_test, and the scope is fabric.
CLI (network-admin@switch) > sflow-collector-create collector-ip 10.10.10.12 collector-port 2055 name sf_test scope fabric
Note: You can add as many Collectors as needed while configuring the sFlow monitoring system in a datacenter.
To delete an already configured sFlow Collector, use the command:
CLI (network-admin@switch) > sflow-collector-delete name name-string
Note: While deleting the sFlow Collectors, note that the last available Collector cannot be deleted if an sFlow is still configured and available. That is, if you want to delete all sFlow Collectors, you must first delete all the sFlows before deleting the last available Collector.
To modify an already created sFlow Collector, use the command:
CLI (network-admin@switch) > sflow-collector-modify name name-string
|
name name-string |
Specify the name of the sFlow you want to modify. |
|
Specify one or more of the following options: |
|
|
collector-ip ip-address |
Specify the change in IP address for the sFlow Collector. |
|
collector-port collector-port-number |
Specify the change in port number for the sFlow Collector. |
Note: You cannot modify the scope parameter once the sFlow Collector is configured.
To view the details of the configured sFlow Collectors, use the sflow-collector-show command specifying one or more of the following options:
CLI (network-admin@switch) > sflow-collector-show
|
Specify one of more of the following options: |
|
|
collector-ip ip-address |
Specify to display the details of the sFlow Collector. |
|
collector-port collector-port-number |
Specify to display the details. |
|
name name-string |
Specify to display the details of the specified sFlow. |
|
scope local|fabric |
Specify to display the details of either the local scoped or fabric scoped sFlow Collectors. |
For example, to view the details of the previously configured sFlow collector, use the command:
CLI (network-admin@switch) > sflow-collector-show
collector-ip collector-port name scope
