Running the Echo Server Test
The Echo Server Test checks connectivity of the entire
system by verifying the ability of the 3C985B-SX server NIC
to send and receive echo packets. to run the Echo Server
Test, two PCs with 3C985B-SX server NICs installed are
required: one PC to send data and one PC to respond.
CAUTION: Running the Echo Server Test while connected
to an active network can cause intermittent failures. To
avoid this, connect to an inactive network on which only
the PC being tested is operating.
To run the Echo Server Test, follow these steps:
1 Make sure that a 3C985B-SX server NIC is installed in
the sending PC and connected to the network.
2 Install a 3C985B-SX server NIC in another PC (the
responder) and connect it to the network.
