To delete a configured collector, use the no sflow collector { ip-address} agent-addr { ipv4-address} [ number [max-datagram-size number]] | [max-datagram-size number] command.

Parameters
sflow collector ip-address Enter the IPv4 (A.B.C.D) of the sFlow collector device.
agent-addr ip-address Enter the IPv4 (A.B.C.D) of the sFlow agent in the router.
number (OPTIONAL) Enter the user datagram protocol (UDP) port number. The range is from 0 to 65535. The default is 6343.

Usage Information

You can configure up to two sFlow collectors (IPv4 or IPv6). If two collectors are configured, traffic samples are sent to both.

The sFlow agent address is carried in a field in SFlow packets and is used by the collector to identify the sFlow agent.

In sFlow, the agent address is a single invariant IPv4 or IPv6 address used to identify the agent to the collector. It is usually assigned the address of a loopback interface on the agent, which provides invariance. The agent address is carried as a field in the payload of the sFlow packets.

As part of the sFlow-MIB, if the SNMP request originates from a configured collector, the system returns the corresponding configured agent IP in the MIB requests. The system checks to ensure that two entries are not configured for the same collector IP with a different agent IP. Should that happen, the system generates the following error: %Error: Different agent-addr attempted for an existing collector .
