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.
IPv6 sFlow collectors and agents are supported on E-Series (ExaScale and
TeraScale), C-Series, and S-Series routers.
To delete a configured collector, enter the
no sflow collector {ipv4-address |
ipv6-address} agent-addr {ipv4-address | ipv6-address} [number [max-datagram-size
number]] | [max-datagram-size number] command.
As part of the sFlow-MIB, if the SNMP request originates from a configured
collector, FTOS will return the corresponding configured agent IP in MIB requests.
FTOS checks to ensure that two entries are not configured for the same collector IP
with a different agent IP. Should that happen, FTOS generates the following error:
%Error: Different agent-addr attempted for an existing collector
number
(OPTIONAL) Enter the UDP port number (User Datagram
Protocol).
Range: 0 to 65535
Default: 6343
max-datagram-size number
(OPTIONAL) Enter the keyword max-datagram-size
followed by the size number in bytes.
Range: 400 to 1500
Default: 1400
