Dell Brocade 6520 Command Reference Supporting Fabric OS v7.1.0 - Page 661

portCfg 2 mtu_size Specifies the maximum transmission unit size. The permitted range is 1260 Bytes to 1500 Bytes. This operand is required. -x | --crossport Configures an interface for a failover crossport. A crossport is defined as the nonlocal (secondary) XGE port to a VE_Port group that provides failover capabilities for the tunnel configured on the local XGE port. For VE_Ports 12-21, xge1 is the local XGE port and xge0 is the crossport. For VE_Ports 22-31, xge0 is the local XGE port and xge1 is the crossport. This operand is optional and supported only on the Brocade FX8-24 XGE ports. delete ipaddr Deletes IP interfaces. Specify the IPv6 or IPv4 address of the virtual port. iproute Defines static IP routes on a GbE port or on a 10GbE port. After defining the IP interface on the remote switch, you can define destination routes for an interface. A maximum of 32 user-configurable routes per GbE/10GbE port are supported. You cannot use this command to configure routes for inband management; use portCfg mgmtroute instead. In Fabric OS v7.0.0, you can use this command to configure an iproute for a XGE port configured as a failover crossport. This feature is supported only on the FX8-24. The syntax for portcfg iproute is as follows: portcfg iproute [slot/]ge_port option args [optional_args] Valid options and arguments for iproute include the following: create dest_ipaddr [netmask] [gateway_router] metric Creates an IP route. Specify the following: dest_ipaddr Specifies the destination IP address in either IPv6 or IPv4 format: dest_IPv6_addr/prefix_len Specifies the destination IPv6 address of the virtual port, if IPv6 is used. The address must be an IPv6 global, unicast address, followed by a prefix. This is used for IPv6 addresses instead of a netmask. The prefix_len operand is required. dest_IPv4_addr netmask Specifies 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 Specifies 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. This operand is optional with IPv6 addresses. If not specified, the gateway_router learned from the Neighbor Discovery protocol is used. -x | --crossport Configures an IP route for a failover crossport. A crossport is defined as the nonlocal (secondary) XGE port to a VE_Port group that provides failover capabilities for the tunnel configured on the local XGE port. For VE_Ports 12-21, xge1 is the local XGE port and xge0 is the crossport. For VE_Ports 22-31, xge0 is the local XGE port and xge1 is the crossport. This operand is optional and supported only on the Brocade FX8-24 XGE ports. Fabric OS Command Reference 633 53-1002746-01
