Network Configuration Examples

This section describes network configuration concepts and includes examples of using the Cisco
EtherSwitch service module to create dedicated network segments and interconnect the segments
through Fast Ethernet and Gigabit Ethernet connections.

Network Design Concepts for Using the Cisco EtherSwitch Service Module
As your network users compete for network bandwidth, it takes longer to send and receive data. When
you configure your network, consider the bandwidth required by your network users and the relative
priority of the network applications they use.

Action
Remove (or power down) the stack master.
Through their Cisco StackWise ports,
1.
connect ten Cisco EtherSwitch service
modules or Catalyst 3750 switch
modules.
Power up all switch modules.

of the remaining stack members becomes the new
stack master. All other stack members in the stack
remain as stack members and do not reboot.
Two Cisco EtherSwitch service modules or
Catalyst 3750 switch modules become stack
masters. One stack master has nine stack members.
The other stack master remains as a standalone
Cisco EtherSwitch service module or Catalyst 3750
switch module.
Use the Mode button and port LEDs on the Cisco
EtherSwitch service modules or Catalyst 3750
switch modules to identify which service modules or
switch modules are stack masters and to witch stack
master they belong.
