xStack® DGS-3600 Series Layer 3 Managed Gigabit Ethernet Switch Figure 2- 86. sFlow Sampler Add window The following fields may be set: Parameter Description Unit Select the unit to configure. From/To Choose the beginning and ending range of ports to be configured for packet sampling. Analyzer Server ID (1-4) Enter the previously configured Analyzer Server ID to state the device that will be receiving datagrams from the Switch. These datagrams will include the sample packet information taken using the sampling mechanism configured here. RX Rate (0-65535) Users can set the rate of packet sampling here. The value entered here is to be multiplied by 256 to get the percentage of packets sampled. For example, if the user enters a figure of 20 into this field, the switch will sample one out of every 5120 packets (20 x 256 = 5120) that pass through the individual port. Users may enter a value between 1 and 65535. An entry of 0 disables the packet sampling. Since this is the default setting, users are reminded to configure a rate here. Otherwise, this function will not work. TX Rate (0-65535) Users can set the rate of packet sampling here. The value entered here is to be multiplied by 256 to get the percentage of packets sampled. For example, if the user enters a figure of 20 into this field, the switch will sample one out of every 5120 packets (20 x 256 = 5120) that pass through the individual port. Users may enter a value between 1 and 65535. An entry of 0 disables the packet sampling. Since this is the default setting, users are reminded to configure a rate here. Otherwise, this function will not work. Max Header Size (18-256) This field will set the number of leading bytes of the sampled packet header. This sampled header will be encapsulated with the datagram to be forwarded to the Analyzer Server. The user may set a value between 18 and 256 bytes. The default setting is 128 bytes.
