Overriding Ethernet Port Configurations

About this task

Use an Ethernet port override to modify a device's Ethernet port configuration.

The following ports are available to NX series service platform models:

NX 5500: ge1, ge2
NX 7500: ge1-ge10, xge1-xge2
NX 9000 series - ge1, ge2 (10GigE ports (xge1-xge4) are available on NX9610 models)

The GE ports are RJ-45 ports supporting 10/100/1000 Mbps or 10/100/1000/2500/5000 Mbps.

The following ports are available on access points:

AP505i: GE1/POE (LAN), GE2 (LAN)
AP510i/e: GE1/POE (LAN), GE2/POE (LAN)
AP560i/h: GE1/POE (LAN), GE2/POE (LAN)

To set an Ethernet port configuration and potentially apply overrides to the profile's configuration:

Procedure

Go to Configuration → Devices.
The Device Configuration screen displays. This screen lists access points, controllers and service platforms within the managed network.
Select a target device by double-clicking on the device name.

Note
You can also select the target device from the device browser in the lower, left-hand, side of the UI.

The selected device's configuration menu displays.
Got to Profile Overrides → Interface → Ethernet Ports .

Note
A blue override icon (to the left of a parameter) defines the parameter as having an override applied. To remove an override go to the Basic Configuration section of the device and click Clear Overrides. This removes all overrides from the device.

Device Overrides - Ethernet Ports Screen

Refer to the following to review port status and assess whether an override is warranted:


Name	The name of the physical port reporting runtime data and statistics. Supported ports vary by model.
Type	The physical port type. Cooper is used on RJ45 Ethernet ports, and Optical materials are used on fiber optic gigabit Ethernet ports.
Description	Displays an administrator defined description for each listed port.
Admin Status	A green check mark means the port is active and currently enabled with the profile. A red "X" means the port is currently disabled and not available for use. The interface status can be modified with the port configuration as needed.
Mode	The profile's switching mode: either Access or Trunk (as defined on the Ethernet Port Basic Configuration screen). If Access is selected, the port accepts packets only from the native VLAN. Frames are forwarded untagged with no 802.1Q header. All frames received on the port are expected as untagged and mapped to the native VLAN. If Trunk is selected, the port allows packets from a list of VLANs added to the trunk. The port supports multiple 802.1Q tagged VLANs and one native VLAN which can be tagged or untagged.
Native VLAN	The VLAN ID (1 - 4094) for the native VLAN. The native VLAN allows an Ethernet device to associate untagged frames to a VLAN when no 802.1Q frame is included in the frame. Additionally, the native VLAN is the VLAN over which untagged traffic is directed when using a port in Trunk mode.
Tag Native VLAN	A green check mark means the native VLAN is tagged. A red "X" means the native VLAN is untagged. When a frame is tagged, the 12-bit frame VLAN ID is added to the 802.1Q header so upstream Ethernet devices know which VLAN ID the frame belongs to. The device reads the 12-bit VLAN ID and forwards the frame to the appropriate VLAN. When a frame is received with no 802.1Q header, the upstream device classifies the frame using the default or native VLAN assigned to the Trunk port. A native VLAN allows an Ethernet device to associate untagged frames to a VLAN when no 802.1Q frame is included in the frame.
Allowed VLANs	The VLANs allowed to send packets over the listed port. Allowed VLANs are listed only when the port is in Trunk mode.
Overrides	If overrides have been applied to the port configuration, click Clear to clear the overrides and revert to the configuration originally defined by the administrator for this interface.
