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.

Tabl e 5 describes what can cause network performance to degrade and how you can configure your

network to increase the bandwidth available to your network users.

Stack master failure Remove (or power down) the stack master. Based on the factors described in the “Stack Master

Election and Re-Election” section on page 14, one

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.

Addition of more than

nine stack members

1. Through their Cisco StackWise ports,

connect ten Cisco EtherSwitch service

modules or Catalyst 3750 switch

modules.

2. Power up all switch modules.

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.
