This chapter takes you through the steps needed to configure the Firewall Services Module (FWSM). This chapter also covers the different FWSM mode configurations: routed, transparent, single context, and multiple contexts.
The FWSM is an inline module in the switch chassis. To configure the FWSM, switch configuration is a necessity because it relates the switch to the FWSM. The configuration of FWSM covers the details of firewall rules, policy, redundancy, and so on.
The configuration of the FWSM is a two-fold process:
Configure the FWSM in the switch.
Configure the FWSM for security rules.
The sections that follow describe this two-fold process in greater detail.
