100 Cisco Systems Intelligent Gigabit Ethernet Switch Module
7.1 Introduction to configuration and integration
The Cisco Systems IGESM module discussed in this document is a standards-based layer 2
switch, with QoS features based on layer 2 through 4 information, using Cisco Systems
Internet Operating System (IOS). It contains most of the features and functionality traditionally
associated with a Cisco switch, in a hot-pluggable module dedicated for use in a BladeCenter.
7.1.1 For those familiar with Cisco Systems switches
This section is for users familiar with Cisco switches using IOS. Although the Cisco Systems
IGESM is based on the feature set available in a Cisco 2950 switch running Enhanced Image
(EI) software,
there are some differences between the Cisco Systems IGESM and a
stand-alone 2950. This is because of the nature of its inclusion in the BladeCenter and
interactions with the Management Module, among other things.
The following sections discuss some of these differences.
Cisco Systems IGESM ports are designated for specific roles and
cannot be re-tasked
Figure 7-1 and Figure 7-2 show two different examples of the port connections to the Cisco
Systems IGESM(s) within the IBM BladeCenter. We then discuss the specific roles and
restrictions for the various ports.
