QB.11-R Installation and Management
QoS (Quality of Service) Parameters (BSU only)
115
The configuration instructions that follow explain how to configure the system so that configuration parameters can
always be changed, and ping requests and responses get higher priority in order to show the actual connectivity of the
pinged node.
The configuration suggested here assumes that the whole network is managed from a single work station, called the
management station. This station can be connected anywhere in the network, and can be recognized by either its IP
address, or by its MAC Ethernet address if the network uses DHCP.
In this configuration, any traffic coming from or going to the management station is treated as management traffic.
Therefore, the management station should be used only for configuration of the TMP.11 nodes in the network and to
check connectivity of the nodes, but it should not be used for any throughput measurements.
CAUTION:
While this QoS configuration is used, the TCP or UDP throughput should not be measured from the
management station.
Step 1: Add Packet Identification Rules
To recognize management traffic, the system needs to recognize ARP requests/responses and any traffic coming from or
going to the management station.
A. Confirm the Attributes of the Existing ARP PIR
The default QoS configuration contains the PIR called “ARP,” which recognizes ARP requests/responses by the
protocol number 0x806 in the Ethernet Type field of the Ethernet packet. Confirm that the ARP PIR parameters are
correct, as follows:
1. Click
Configure > QoS > QoS PIR
.
2. Click the
Details
button next to the ARP PIR.
3. Confirm the following attributes:
•
Rule Name
: ARP
•
Status
: Enable
•
Enable Ether Type Rule
: Yes (box is checked)
–
Ether Type
: 1
–
Ether Value
: 08:06
B. Create New PIRs to Recognize Management Traffic
To recognize the traffic coming from or going to the management station, the system must contain two additional PIRs:
one with either the destination IP address or the destination MAC address equal to the management station’s IP or
MAC address, and another with either the source IP address or the source MAC address equal to the management
station’s IP or MAC address.
1. Click
Configure > QoS > QoS PIR
.
2. Click
Add Table Entries
.
3. First you will configure the Destination Address PIR.
Enter the
Rule Name:
Management Station DST MAC Addr
if you are using a MAC addresses, or
Management
Station DST IP Addr
if you are using a IP addresses.
4. Set the
Entry Status
to Enable.
5. Click
Add
. The DST Management PIR will be added to the PIR list.
6. Click the
Details
button next to the DST Management PIR you just created.
7. Scroll down to the
Destination IP Table
or the
Destination MAC Table
, depending on your configuration
requirements, and click
Add Table Entries
.
8. Enter the following information:
•
IP Address
or
MAC Address
: IP address or MAC Address of management station
