Creating IP interfaces and routes The IP network connection between two HP StorageWorks 400 Multi-Protocol Routers or two FR4-18i blades or one HP StorageWorks 400 Multi-Protocol Router and one FR4-18i blade is configured by defining IP interfaces for origin and destination virtual ports, and then defining one or more IP routes to connect them. 1. Define the IP interface of each virtual port, using the portCfg command. You can define up to eight IP interfaces per GbE port. The command syntax is as follows. portCfg ipif [slot/]ge0|ge1 create src_ipaddr mtu_size where: slot The number of a slot in an HP StorageWorks 4/256 SAN Director and HP StorageWorks DC SAN Backbone Director and HP StorageWorks DC04 SAN Director platforms that contains an FR4-18i blade. This parameter does not apply to the stand-alone HP StorageWorks 400 Multi-Protocol Router. ge0|ge1 src_ipaddr The Ethernet port used by the tunnel (ge0 or ge1). The source IP address in either IPv6 or IPv4 format: src_IPv6_addr/[prefix_len] Specifies the source IPv6 address of the virtual port if IPv6 is used. The address must be an IPv6 global, Unicast address. As an option, specify the prefix length. This is used for IPv6 addresses instead of a netmask. If prefix_len is not specified, the prefix length learned from the Neighbor Discovery protocol will be used. src_IPv4_addr netmask Specifies the source IPv4 address of the virtual port, if IPv4 is used. If an IPv4 address is used, the subnet mask must be specified as well (in a.b.c.d. format.) mtu_size The maximum transmission unit size. The range allowed is 1260 to 2348 B. HP recommends that you set the value to 1500 B, which is the normal value in an Ethernet network. Some networks support jumbo packets (packets larger than 1500 B). If the network you are using supports jumbo packets, a value of 2348 can improve performance. By default, the virtual ports will automatically become VE_Ports. 2. Define IP routes on a GbE port. After defining the IP interface of the remote switch, you can define destination routes on an interface. You can specify a maximum of 32 routes per GbE port. The command syntax is as follows. portCfg iproute [slot/]ge0|ge1 create dest_ipaddr gateway_router [metric] where: slot The number of a slot in an HP StorageWorks 4/256 SAN Director, an HP StorageWorks DC SAN Backbone Director or HP StorageWorks DC04 SAN Director Switch enterprise-class platform that contains an FR4-18i blade. This parameter does not apply to the stand-alone HP StorageWorks 400 Multi-Protocol Router. ge0|ge1 The Ethernet port used by the tunnel (ge0 or ge1). dest_ipaddr The source IP address in either IPv6 or IPv4 format: dest_IPv6_addr/[prefix_len] The destination IPv6 address of the virtual port, if IPv6 is used. The address must be an IPv6 global, unicast address. As an option, specify the prefix length. This is used for IPv6 addresses instead of a netmask. If prefix_len is not specified, the prefix length learned from the Neighbor Discovery protocol will be used. dest_IPv4_addr netmask The destination IPv4 address of the virtual port, if IPv4 is used. If an IPv4 address is used, the subnet mask must be specified as well. Use a.b.c.d. format. gateway_router The IP address of an IP router that can route packets to the destination virtual port IP address. The gateway address must be on the same IP subnet as one of the port IP addresses. metric The link metric associated with the route. Valid values are 0-255. The default value is 0. A low value encourages the use of the route, and a high value discourages the use of a route. 476 Configuring and monitoring FCIP extension services
