Example of disabling FC Fastwrite on a switch : switch:admin> fastwritecfg --disable 7 !!!! WARNING !!!! Disabling FC Fastwrite will require powering off and back on the and it may take upto 5 minutes. For non bladed system, the switch will be rebooted. Data traffic will be disrupted. Continue (Y,y,N,n): [ n] y Slot 7 is being powered off Disabling FC Fastwrite on a port 1. Connect to the switch and log in using an account assigned to the admin role. 2. Issue the following command: switch:admin> portcfg fastwrite [slot/]port --disable where slot is the slot in which the FR4-18i is installed, and port is the port number. A slot number is not required for the 400 Multi-Protocol Router. FCIP services configuration guidelines There are multiple configuration requirements and options associated with FCIP services. The following general guidelines may be helpful. The steps are presented in an order that minimizes the number of times ports need to be disabled and enabled. In practice, the steps do not have to be taken in this order. 1. Determine whether you are implementing IPSec. IPSec configuration may be done at any time, but defining IPSec policies first ensures that they will be available when FCIP tunnels are configured. See "" on page 421 for specific instructions. 2. Determine which FCIP tunnel you want to configure. Each FCIP tunnel is associated with a specific virtual port, and a specific Ethernet port, as shown in Table 84 on page 385. For example, if you want to configure FCIP tunnel 0, you need to configure virtual port 16, and define an IP interface and one or more IP routes over Ge0. 3. Persistently disable the virtual ports before you configure them. Ports on a new 400 Multi-protocol Router or FR4-18i blade are persistently disabled by default. On a 400 Multi-protocol Router or FR4-18i blade that has already been installed and configured, check the EX port status using the portcfgshow command, and persistently disable the ports using the portcfgpersistentdisable command before you configure them. See "" on page 421 for a description. 4. The Ethernet port associated with the tunnel should also be disabled. Before disabling an Ethernet port, be sure there are no other tunnels active on the port. If there are, disabling the port will disable the tunnel or tunnels. 5. Determine whether any of the Virtual ports should be VEX ports, and configure them using the portcfgvexport command. See "Managing FCIP tunnels" on page 409 for specific instructions. 6. Create an IP interface using the portcfg ipif command. See "Managing FCIP tunnels" on page 409 for specific instructions. 7. Create one or more IP routes using the portcfg iproute command. See "Managing FCIP tunnels" on page 409 for specific instructions. 8. If you are implementing VLAN tagging, create a static ARP entry for the IP interface using the portcfg arp command. See "Configuring and enabling FC Fastwrite" on page 398 for specific instructions. 9. Create an FCIP tunnel using the portcfg fciptunnel command. See "FICON fabrics" on page 423 for specific instructions. 10. If you are implementing FICON emulation, configure FICON emulation using the portcfg ficon command. See "FICON fabrics" on page 423 for specific instructions. Fabric OS 6.1.x administrator guide 401
