3 Configuring cluster links Configuring cluster links Each encryption switch or FS8-18 blade has two GbE ports labeled Ge0 and Ge1. The Ge0 and Ge1 ports connect encryption switches and FS8-18 blades to other encryption switches and FS8-18 blades. These two ports are bonded together as a single virtual network interface. Only one IP address is used. The ports provide link layer redundancy, and are collectively referred to as the cluster link. All encryption switches or blades in an encryption group must be interconnected by their cluster links through a dedicated LAN. Both ports of each encryption switch or blade must be connected to the same IP network, and the same subnet. Static IP addresses should be assigned. VLANs should not be used, and DHCP should not be used. 1. Log into the switch as Admin or FabricAdmin. 2. Configure the IP address using the ipaddrset command. Only Ge0 needs to be configured. Always use ipaddrset -eth0 to configure the address. If an address is assigned to ge1 (-eth1), it is accepted and stored, but it is ignored. Only IPv4 addresses are supported for cluster links. The following example configures a static IP address and gateway address for the bonded interface. switch:admin> ipaddrset -eth0 --add 10.32.33.34/23 switch:admin> ipaddrset -gate --add 10.32.1.1 Special consideration for blades For FS8-18 blades, the slot number must also be included in the ipaddrset command, for example: switch:admin> ipaddrset -slot 7 -eth0 --add 10.32.33.34/23 switch:admin> ipaddrset -slot 7 -gate --add 10.32.1.1 There are additional considerations if blades are removed and replaced, or moved to a different slot. On chassis-based systems, IP addresses are assigned to the slot rather than the blade, and are saved in non-volatile storage on the control processor blades. IP addresses may be assigned even if no blade is present. If an FS8-18 blade is installed in a slot that was previously configured for a different type of blade with two IP ports (an FC4-16E blade, for example), the FS8-18 blade is assigned the address specified for -eth0 in that slot. To be sure the correct IP addresses are assigned, use the ipaddrshow command to display the IP address assignments as shown in the following example. switch:admin> ipaddrshow -slot 7 SWITCH Ethernet IP Address: 10.33.54.207 Ethernet Subnetmask: 255.255.240.0 Fibre Channel IP Address: none Fibre Channel Subnetmask: none Gateway IP Address: 10.33.48.1 DHCP: Off eth0: 10.33.54.208/20 eth1: none/none Gateway: 10.33.48.1 98 Fabric OS Encryption Administrator's Guide 53-1001864-01
