Enabling the IP Network Simulator

Because the network simulator commands and functionality are part of the SAN Extension Tuner, you
must first enable the tuner; after doing so, you can view and use the network simulator commands in
EXEC mode.
To enable the network simulator (in this case, on a Cisco MDS 9506 director), follow these steps:
Command
Step 1
switch# config t
switch(config)#
Step 2
switch(config)# feature san-ext-tuner
Step 3
switch(config)# exit
switch#
Step 4
switch# ips netsim enable interface
gigabitethernet 2/3 gigabitethernet 2/4
switch# ips no netsim enable interface
gigabitethernet 2/3 gigabit ethernet 2/4

Simulating Network Delays

You can configure the network simulator to delay all packets entering the Gigabit Ethernet ports. After
configuring the delay in one direction, you need to also enter the same command to introduce the delay
in the opposite direction, if desired. You can specify the delay in either milliseconds (allowable range is
0 to150 ms) or microseconds (allowable range is 0 to 150000 µs).

Purpose
Enters configuration mode.
Enables the SAN Extension Tuner.
Exits to EXEC mode.
Configures the pair of Gigabit Ethernet ports in
network simulation mode.
The two ports must be adjacent to each; the
Note
first port must be an odd-numbered port.
