sflow collector
Configure a collector device to which sFlow datagrams are forwarded.
Syntax
sflow collector {ip-address} agent-addr {ip-address} [number [max-datagram-size
number]] | [max-datagram-size number]
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.
max-datagram-size
number
(OPTIONAL) Enter the keyword max-datagram-size then the size number in bytes. The
range is from 400 to 1500. The default is 1400.
Defaults Not configured.

Version Description
8.3.16.1 Introduced on the MXL 10/40GbE Switch IO Module.
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.
sflow enable (Global)
Enable sFlow globally.
Syntax
sflow enable
To disable sFlow, use the no sflow enable command.
