ip sla control protocol (udp 1967)

ROMAN TOMASEK

The IP SLA uses the control protocol for information about a destination port on the rtr responder for a synthetic traffic. The synthetic traffic starts from the source device after OK is received from the rtr responder. But what's happend when the target device is a server (IP device with an open port for the synthetic traffic)?? Is the control protocol send to the server too?How the source device recognizes that the target device is the rtr responder or a server?? Thank you.

When defining your collector, one of the subcommands is "control disable". For example:

udp-jitter 1.1.1.1 14600 control disable

The control data should be disabled unless the target is a responder enabled device. If you do not disable the control packets, then your collector will fail. Operations like icmpEcho, tcpConnect, etc. should not use control packets when communicating with a server. You want the control packets when you're doing a udpJitter operation to a responder device.

Hello,

how can I disable the control data?? There is some CLI command for this disabling?? Thank you.

udp-jitter 1.1.1.1 14600 control disable

Hi,

According to http://www.iana.org/assignments/port-numbers, Cisco IP SLA Control Protocol port are:

cisco-ipsla - 1167/tcp

cisco-ipsla - 1167/udp

cisco-ipsla - 1167/sctp

Did the owner of this topic mistype the port number or Cisco IP SLA also uses UDP 1967 beside those ports above?

Thanks,

Antonio

No, udp/1967 is the control port. Port 1167 is the SCTP registration port number.
