nettest run duplex
Runs the duplex matching test.
Syntax
nettest run duplex <interface> {ipv6-target <ipv6-address> | target <ipv4-address>}
Parameters
<interface> | Duplex interface. |
ipv6-target <ipv6-address> | Specifies the target IPv6 address to reach. |
target <ipv4-address> | Specifies the target IPv4 address to reach. |
Usage
Determines if the speed and duplex settings match on each side of the default gateway connection. If one side is different from the other, then traffic is sent at different rates on each side, causing a great deal of collision. This test runs the ping utility for 5 seconds with a packet size of 2500 bytes against the default gateway.
Optionally, select an interface to test. The more interfaces you test, the longer it takes the diagnostics to run. If you do not specify an interface, the SteelHead runs the duplex test on all interfaces.
The test passes if the system acknowledges 100% of the packets and a receives responses from all packets. If any packets are lost, the test fails.
If the test fails, ensure that the speed and duplex settings of the appliance's Ethernet interfaces match those of the switch ports to which they are connected.
The test output records the percentage of any lost packets and number of collisions.
Note: For accurate test results, traffic must be running through the SteelHead.
