Managing Interfaces

---

Fabric Manager allows you to configure and monitor interfaces on multiple Cisco 9000 switches. The Device Manager allows you to configure and monitor interfaces on a single Cisco 9000 switch.

This chapter describes how to configure interfaces using the Fabric Manager and Device Manager. For information about interfaces and configuring them using the command-line interface (CLI), refer to the Cisco 9000 Family Configuration Guide. This chapter includes the following sections:

•Managing Ports

•Managing PortChannel Interfaces

•Monitoring Port Statistics

Managing Ports

This section describes how to enable, disable, configure, and view port attributes and statistics. It includes the following topics:

•Enabling or Disabling Ports

•Managing General Port Attributes

•Managing Interface Attributes for Ports

•Viewing FLOGI Attributes

•Viewing Port ELP Attributes

•Viewing Trunking Information

•Managing Physical Attributes for a Port

•Viewing Port Capability Attributes

Enabling or Disabling Ports

To enable a port, right-click on a disabled port in Device Manager and choose Enable from the pop-up menu.

To disable a port, right-click on a enabled port in Device Manager and choose Disable from the pop-up menu.

To enable or disable multiple ports, ctrl-click each port or drag the mouse around a group of ports. Then right-click any of the selected ports and click either Enable or Disable from the pop-up menu.

Managing General Port Attributes

To manage general port attributes, such as Alias, PortVsan, and Admin Mode from the Fabric Manager, select the Switch tab at the bottom of the screen and choose Interface from the menu tree and then choose the type of port. To manage these attributes from the Device Manager, choose the type of port from the Interface menu. You can select FxPorts, xEPorts, Enabled Ports, All Ports, or the Mgmt Port.

The following are the different port types supported by the Cisco MDS 9000 Family.

•xE ports:

–An E_Port (expansion port) connects two switches and can carry frames between switches for configuration and management of the fabric for a single VSAN.

–A TE_Port (trunking expansion port) allows a link between two Cisco 9000 switches to carry traffic for multiple VSANs.

•Fx ports:

–An F_Port (fabric port) connects to an N_Port (end node port) on a host node through a point-to-point link.

–An Fl_Port (fabric loop port) connects to an NL_Port (end node loop port) on a public loop through a point-to-point link or an arbitrated loop.

•A TL (translative loop) port may be connected to one or more private loop devices (NL ports). TL ports are unique to Cisco MDS 9000 Family switches and have similar properties to FL ports. The default is Auto, so the switch will autonegotiate the port speed.

For further information about port types, refer to the Cisco 9000 Family Configuration Guide.

The dialog boxes from the Fabric Manager display attributes for multiple switches. Figure 7-1 shows the dialog box with the General tab selected from the Device Manager, which displays general attributes for a single switch.

RuntFramesIn	Displays the number of frames received by the port that are shorter than the minimum allowable frame length, whether the CRC is good or not.
JabberFramesIn	Displays the number of frames received by the port that are longer than a maximum frame length, and also have a CRC error.
FramesTooLong	Displays the number of frames received by the port where the frame length was greater than what was agreed to in FLOGI/PLOGI. This could be caused by losing the end-of-frame delimiter.
FramesTooShort	Displays the number of frames received by the port where the frame length was less than the minimum indicated by the frame header. Normally the frame-length minimum is 24 bytes, but it could be more if the DFCTL field indicates an optional header should be present.
FramingErrorFrames	Displays the number of framing errors.
ELPFailures	Displays the number of ELP switch fabric internal link service request failures detected by the port. This attribute is applicable only to interconnect ports, which are E_Ports or B_Ports.

Managing PortChannels

To create a PortChannel from Fabric Manager, right-click two or more Inter-Switch Links (ISLs) and select PortChannel from the pop-up menu. You see the dialog box shown in Figure 7-6.

Figure 7-6 Create PortChannel Dialog Box

To add a link to an existing PortChannel, right-click an ISL on the Fabric Manager map and select PortChannel from the pop-up menu. You see the confirmation prompt shown in Figure 7-7.

Figure 7-7 Add to Port Channel Confirmation Prompt

Click Add to add a link to a PortChannel when the ports on each link and at both ends of the link have the same port speed, trunking type, and administrative state.

To force the addition of the link to a PortChannel, regardless of the port attributes, click the ForceAdd button.

Note To create a PortChannel, all the ports on both ends of the link must have the same port speed, trunking type, and administrative state.
