2 ifModeShow ifModeShow Synopsis Displays the link operating mode and MAC address for a network interface. ifmodeshow interface Description Use this command to display the link operating mode and MAC address for a network interface. On the CP of a Brocade DCX or DCX-S4, this command supports eth0 and eth3 as interface parameters. On all other platforms, only eth0 is supported. The CP on a Brocade DCX or DCX-S4 has two external physical Ethernet management ports, eth1 and eth3. Both interfaces are bonded together to form a single logical interface, bond0. The management port IP addresses are assigned to the logical interface, bond0. Link layer Ethernet operations are applied to the physical interfaces, eth0 and eth3. Ethernet bonding provides link layer redundancy using the active-standby failover model. The two Ethernet ports must be part of the same subnet. By default, all traffic is transmitted over the active Ethernet port, eth0. The second Ethernet port, eth3, acts as a standby interface and no traffic is transmitted over it. When the active Ethernet port is disconnected, the alternate Ethernet port becomes active. When the system reboots, the Ethernet port eth0 is always made active if it is connected. When executed with the bond0 operand, ifModeShow displays the active Ethernet port Note The execution of this command is subject to Virtual Fabric or Admin Domain restrictions that may be in place. Refer to chapter 1, "Using Fabric OS commands" and Appendix A, "Command Availability" for details. Operands This command has the following operand: interface Specifies the name of the interface, optionally enclosed in double quotation marks. Valid interfaces are: eth0 |eth3 Displays the link operating mode of the specified interface. The value eth3 is valid only on the CP of a Brocade DCX or DCX-4S. bond0 Displays the active Ethernet port. This operand is valid only on the CP of a DCX or a DCX-S4. Examples To display the link operating mode for the eth0 Ethernet interface: switch:admin> ifmodeshow eth0 Link mode: negotiated 100baseTx-HD, link ok MAC Address: 00:60:69:D0:24:40 To display the link operating mode for the eth3 Ethernet interface (in this example, the management port is disconnected): switch:admin> ifmodeshow eth3 Link mode: no link MAC Address: 00:05:1E:40:62:30 376 Fabric OS Command Reference 53-1001337-01
