Configuring Ethernet Interfaces


This section describes the configuration of the Ethernet interfaces on the Cisco Nexus 5000 Series switches. It includes the following sections:

Information About Ethernet Interfaces

The Ethernet ports can operate as standard Ethernet interfaces connected to servers or to a LAN.

The Ethernet interfaces also support Fibre Channel over Ethernet (FCoE). FCoE allows the physical Ethernet link to carry both Ethernet and Fibre Channel traffic.

On the Cisco Nexus 5000 Series switch, the Ethernet interfaces are enabled by default.

Configuring Ethernet Interfaces

Fabric Manager and Device Manager display configuration settings and status information about the physical Ethernet interfaces on Cisco Nexus 5000 Series switches. However, you cannot change the configuration for physical Ethernet interfaces using Fabric Manager or Device Manager.

Displaying Interface Information

Fabric Manager and Device Manager display configuration settings and status information about the physical Ethernet interfaces on Cisco Nexus 5000 Series switches.

To display Ethernet interfaces using Fabric Manager, follow these steps:


Step 1 In the Physical Attributes pane, expand Switches > Interfaces and then select Ethernet.

You see the Ethernet interface information pane as shown in Figure 8-1.

The General tab displays the description, speed, MAC address and status for each interface.

Step 2 Select the VLAN tab to display the VLAN assigned to each interface.

Step 3 Select the CDP Neighbors tab to display the CDP neighbor assigned to each interface.


Default Physical Ethernet Settings

The following table lists the default settings for all physical Ethernet interfaces:

Parameter
Default Setting

Debounce

Enable, 100 milliseconds

Duplex

Auto (full-duplex)

Encapsulation

ARPA

MTU1

1500 bytes

Port Mode

Access

Speed

Auto (10000)

1 MTU cannot be changed per-physical Ethernet interface. You modify MTU by selecting maps of QoS classes.
