xStack® DGS-3600 Series Layer 3 Managed Gigabit Ethernet Switch following parameters to determine the color rate of the IP packet flow. CIR - The Committed Information Rate can be set between 0 and 156249. IP flow rates at or below this level will be considered green. IP flow rates that exceed this rate but not the PIR rate are considered yellow. PIR - The Peak information Rate. IP flow rates that exceed this setting will be considered as red. This field must be set at an equal or higher value than the CIR. CBS - The Committed Burst Size. Used to gauge packets that are larger than the normal IP packets. Click the check box to employ the CBS. This field does not have to be set for this feature to function properly but is to be used in conjunction with the CIR setting. The CBS should be configured to accept the biggest IP packet that is expected in the IP flow. PBS - The Peak Burst Size. This optional field is to be used in conjunction with the PIR. The PBS should be configured to accept the biggest IP packet that is expected in the IP flow. srTCM Choosing this field will allow users to employ the Single Rate Three Color Mode and set the following parameters to determine the color rate of the IP packet flow. CIR - The Committed Information Rate can be set between 0 and 156249. The color rates are based on the following two fields which are used in conjunction with the CIR. CBS - Committed Burst Size. Measured in bytes, the CBS is associated with the CIR and is used to identify packets that exceed the normal boundaries of packet size. The CBS should be configured to accept the biggest IP packet that is expected in the IP flow. Packet flows that are lower than this configured value are marked green. Packet flows that exceed this value but are less than the EBS value are marked yellow. EBS - Excess Burst Size. Measured in bytes, the EBS is associated with the CIR and is used to identify packets that exceed the boundaries of the CBS packet size. The EBS is to be configured for an equal or larger rate than the CBS. Packet flows that exceed this value are marked as red. Action This field is used to determine the course of action when a packet flow has been marked as a color, based on the following fields. Conform This field denotes the green packet flow. Green packet flows may have their DSCP field rewritten to a value stated in this field. Users may also choose to count green packets by ticking the Counter check box. Exceed This field denotes the yellow packet flow. Yellow packet flows may have excess packets permitted through or dropped. Users may replace the DSCP field of these packets by checking its radio button and entering a new DSCP value in the allotted field. Users may also choose to count yellow packets by ticking the Counter check box. Violate This field denotes the red packet flow. Red packet flows may have excess packets permitted through or dropped. Users may replace the DSCP field of these packets by checking its radio button and entering a new DSCP value in the allotted field. Users may also choose to count yellow packets by ticking the Counter check box. Click Apply to save changes made.
