CCNP TSHOOT 6.0 - The Cisco Learning Network

CCNPv6 TSHOOT
a. On DLS2, the device that will perform the receiving (server) side of the connection, issue the ttcp
command. You are prompted for information about this connection. You can accept the default values
or enter new values. You can also use the command line to enter all the parameters as one
command. The command generated is shown after the last entry prompt.
As TTCP waits for the transmitting (client) side to make a connection, the console screen freezes.
DLS2#ttcp
transmit or receive [receive]:
receive packets asynchronously [n]:

rcvwndsize=32768, delayedack=yes tcp
b. On ALS1, the device that will perform the client side of the connection, you must specify that this side
is the transmitting side because the default is to run in receive mode. You must also specify the IP
address of the receiving side (DLS2) to initiate the connection.

The DLS2 (receive) side of the connection shows the following information when the transfer
completes:
