Networking Concepts and Technology: A Designers Resource

A high-level overview of the switch configuration is shown in FIGURE 7-18.

Configuring the Extreme Networks Switches

For the multi-tier data center, two Extreme Networks BlackDiamond switches were used for the core switches and one Summit7i switch was used for the edge switch.

Note

Network equipment from Foundry Networks can be used instead. See "Configuring the Foundry Networks Switches" on page 324.

To Configure the Extreme Networks Switches

1. Configure the core switches. The following example shows an excerpt of the switch configuration file.

2. Configure the edge switch. The following example shows an excerpt of the switch configuration file.

Configuring the Foundry Networks Switches

This section describes the network architecture implementation using Foundry Networks equipment instead of Extreme Networks equipment. The overall setup is shown in FIGURE 7-19.

Master Core Switch Configuration

CODE EXAMPLE 7-1 shows an example of the configuration file for the master core switch (called MLS0 in the lab). We used the Foundry Networks BigIron switch.

Code example 7-1. MLS0 Configuration File

Standby Core Switch Configuration

CODE EXAMPLE 7-2 shows a partial listing of the configuration file for the standby core switch (called MLS1 in the lab). Again we used the Foundry Networks BigIron switch.

Code example 7-2. MLS1 Configuration File
