1. To IP Address - Enter the remote agent IP Address.
2. From IP Address - Select the originating IP address that the 9145E will place into the test
packets. Use Space to scroll through Auto Selection, Management IP, Test IP, and Aux IP.
The Auto Selection setting will start first with the Test IP. If the To IP Address is in the Test Network
Subnet, the Test IP will be used in the packet. If the Test IP is not available or the To IP Address is
not in the Test Network Subnet, the Aux IP is checked. If the Aux IP is not available or the To IP
Address is not the Aux Network Subnet, the Manager IP is used. Any address can be used with
the Manager IP since it has access to the Default Gateway.
If the From IP Address is specified as the Test IP or the Aux IP, and the To IP Address is not
located in the matching subnet, the destination is unreachable. An error message is displayed
when the Start Test command is given.
3. Test VLAN - The test packets will carry this VLAN Tag. The Test VLAN can only be changed if the
From IP Address is set to the Test IP, or the if Aux Allow Any VLAN is enabled.
4. Test Packets per sec - Controls the number of packets that will be sent for every second the test
runs. Settings are: 1, 2, 5, 10, 20, 50 or 100.
5. Packet Timeout sec (1 - 10) - Set the packet timeout for this test, from 1 to 10 seconds. If a
response is not received within this time limit, the packet will be considered dropped.
6. Packet Priority - Set packet Priority Code Point (PCP) from 0 to 7, with 0 being the highest
priority.
7. Packet DSCP Code (0 - 63) - The Differentiated Services Code Point (DSCP) code used to
classify packets in a Diffserv network. Other network devices that support Diffserv use the DSCP
code in the IP header to select a per hub behavior (PHB) for the packet and provide the
appropriate QoS treatment.
8. Packet DF Bit - The DF (Don’t Fragment) Bit is an identifier in the packet that determines if this
packet can be fragmented to smaller packets.
9. Test Duration min:sec - Sets the amount of time the test will run in minutes and seconds. A
setting of 0 will allow the test to run forever.
10. Min Test Payload Size (40 - 9950) - Set the minimum test size, in bytes. The 9145E sends test
packets ranging in size from the minimum packet setting to the maximum packet setting (sweep), if
they are different. The minimum payload size must be less than, or equal to, the maximum payload
size. If a sweep is being performed, the size will be incremented by 1 byte for each message sent
until the maximum test payload size is reached, the decremented by 1 byte for each message sent
until the minimum payload size is reached, then repeated as necessary.
11. Max Test Payload (40 - 9950) - Set the maximum test payload size, in bytes. The maximum
payload size must be equal to, or greater than, the minimum payload size.
NOTE: If the DF Bit is clear, the actual maximum packet size is 8192. The DF
Bit must be set for oversized packets greater than 1518 (payload size
greater than 1472) to be sent or the packet will be fragmented (sent
as multiple packets of size 1518).
12. Start/Stop Test - Start and Stop testing.
