4 Basic Layer 2 Setup and Buffer Tuning of the S25P for Storage Environments
Setting Up Layer 2 Switching 
The following screenshot illustrates the use of these commands (use a space before and after the hyphen): 
Step Task Command Syntax Command Mode
1 Select all ports. 
This example assumes that the stack ID is 0. 
The prompt changes to: 
Force10(conf-if-range-gi-0/1-24)#
interface range gi 0/1 - 24
(A space is required before and 
after the dash in the command.)
CONFIGURATION
2 Enable the selected ports for Layer 2 switching.
switchport
INTERFACE RANGE
3 Set the maximum Link MTU (frame size) to handle 
Jumbo frames.
mtu 9252
INTERFACE RANGE
4 Administratively enable all ports.
no shutdown
INTERFACE RANGE
5 Return to CONFIGURATION mode.
exit
INTERFACE RANGE
6 Repeat the above sequence for the 10GbE ports.
interface range te 0/25 - 28
CONFIGURATION
7 After physically connecting the ports, use the 
show 
ip interfaces brief
 command to inspect 
administrative status (the Status field in the output) 
and link status (the Protocol field).
