2. ## Installing and Configuring Ethernet Switches To provide a redundant network, a cluster has two Ethernet switches. The Foundation Services have been validated on Cisco Catalyst 29x0 Desktop Switches. Note - If you use other switches, check that the switches support the following: Simple Network Management Protocol (SNMP) Management information base (MIB) RFC 1213 and RFC 1493 Ability to disable Spanning Tree Protocol The documentation for Cisco Catalyst 29x0 Desktop Switches is located at: `http://www.cisco.com/univercd/cc/td/doc/product/lan` ### To Assign IP Addresses to Cisco 29x0 Ethernet Switches Assign IP addresses manually to the Cisco 29x0 switches. If IP addresses are not assigned manually, the Dynamic Host Configuration Protocol (DHCP) attempts to assign IP addresses, which might result in errors. Connect to the console of the switch. Type the following series of commands on the console window:
       switch1>enable
       switch1#config term
       Enter configuration commands, one per line.  End with CNTL/Z.
       switch1(config)#ip address IP-address 255.255.255.0
       switch1(config)#interface VLAN1
       switch1(config-if)#hostname switch-hostname
       switch1(config)#end
       switch1#copy run start
       Destination filename [startup-config]?
   switch-hostname | Is The host name that you assign to the switch.
   IP-address | Is The IP address that you associate with the host name. This address should be an IP address on your company's network.
2. Press Return to confirm these commands and that the configuration file is `startup-config`. Repeat Step 1 through Step 3 for the other switch to assign the second IP address. ### To Disable the Spanning Tree Protocol for Cisco 29x0 Ethernet Switches The Spanning Tree Protocol (STP) ensures that a loop occurs when you have redundant paths in your network. There should be no loops between the redundant networks in the Foundation Services cluster network because such networks are completely separate. There should be no crossover link between the two redundant switches. Therefore, you must disable the STP. To disable the STP, see the documentation that is supplied with your Ethernet switch. The STP should also be disabled for any additional virtual local area networks (VLANs) used in your cluster. An example of the commands that you can use are as follows: Connect to the console of the switch. Type the following series of commands on the console window of the switch:
       switch1>enable
       switch1#config term
       Enter configuration commands, one per line.  End with CNTL/Z.
       switch1(config)#no spanning-tree vlan 1
       switch1(config)#end
       switch1#copy run start
       Destination filename [startup-config]?
Press Return to confirm that the STP has been disabled and that the configuration file is `startup-config`. Repeat Step 1 through Step 3 for the other switch to disable the STP. ## Installing and Configuring Supplemental Ethernet Cards for External Access Supplemental Ethernet interface cards enable you to configure external access to your cluster. These cards are optional. For Netra CT 410, Netra CT 810, and Netra CT 820 servers, you can install the supplemental PMC Ethernet cards with the documentation that is provided. For Netra 20 servers, you can install an additional HME Ethernet card or QFE Ethernet card. Alternatively, you can configure the unused ports of QFE cards already present on the server. For Netra 240 servers, you can install additional Gigabit Ethernet cards.
