To edit an entry that has already been configured, click the Modify button of an entry in the sFlow Sampler Settings window
which will produce the following window for the user to configure. This window holds the same information as the previous Add
window and therefore, the previous descriptions of the parameters remain valid here. Click Apply to save changes made to this
window.
Please note that the Analyzer Server ID cannot be changed in this window. To change this setting, users must delete this entry and
configure a new entry with a new Analyzer server ID.
xStack DGS-3600 Series Layer 3 Gigabit Ethernet Managed Switch
Description
Choose the beginning port of the range of ports to be configured for packet sampling.
Choose the ending port of the range of ports to be configured for packet sampling.
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.
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 or this function will not function.
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.
