Creating and Managing Fabric Profiles
A Fabric profile contains configuration settings for a gateway Fibre Channel (FC) fabric. A gateway FC fabric creates associations that connect Fibre Channel over Ethernet (FCoE) devices with converged network adapters (CNAs) on the Ethernet network to an FC switch on the Fibre Channel network. You can assign Fabric profiles to QFX Series devices that act as a FCoE-FC gateway, to configure gateway FC fabrics.
To manage or create FC Gateway Service profiles: In Build mode, select Wired > System > Fabric in the Tasks pane. The FC Gateway Service Profile page appears.

Managing Fabric Profiles
From the Manage Fabric Profiles page, you can:
Create a new profile by clicking Add.
Modify an existing profile by selecting it and clicking Edit.
Associate a profile to specific interfaces by selecting it and clicking Assign.
During the assignment process, you will have the option to configure interface-specific settings.
Change a profile’s current interface assignments by selecting it and clicking Edit Assignments.
View information about a profile by selecting the group and clicking Details or by clicking the profile name.
Clone a profile by selecting a profile and clicking Clone.
Delete profiles by selecting the profile and clicking Delete.
You cannot delete profiles that are in use—that is, assigned to objects or used by other profiles. To see the current assignments for a profile, select the profile and click Details.
Table 1 describes the information provided about Fabric profiles on the Manage Fabric Profiles page. This page lists all Fabric profiles defined for your network, regardless of your current selected scope in the network view.
Table 1: Fabric Profile Information
Name given to the profile when it was created.
Number from 1 through 4094 assigned to the Fabric profile when it was created.
Device family to which the profile applies.
Any description added when the profile was created.
One of the following:
Date and time when this profile was created.
Last Updated Time
Date and time when this profile was last modified.
The username of the user who created or modified the profile.
All columns might not be displayed. To show or hide fields in the table, click the down arrow on the field header, select Columns, and select or clear the check box adjacent to the field that you want to show or hide.
Creating Fabric Profiles
To create a Fabric profile:
- From the Network Director Banner, select Build mode.
- In the Tasks pane, select Wired > System > Fabric.
The Manage Fabric profiles page appears.
- Click Add.
The Create Fabric Profile page appears.
- Enter settings for the Fabric profile as described in Specifying Settings for a Fabric profile.
- Click Done.
Specifying Settings for a Fabric profile
Use the Create Fabric profile page to define a common set of attributes in a Fabric profile, which you can then apply to Fibre Channel (FC) interfaces on Data Center Switching devices.
You can reference VLAN profiles in a Fabric profile. Create these profiles before you create Fabric profiles.
After you create a Fabric profile, you can assign it to devices, individual interfaces, or port groups. During this process, you can also configure interface-specific attributes. You can assign only one Fabric profile to an interface or port group.
Table 2 describes the Fabric profile settings. Mandatory settings are indicated by a red asterisk (*) that appears next to the field label in the user interface.
Table 2: Fabric Profile Settings
Type a name for the profile.
The value must be a string between 2 and 64 characters long, begin with a letter, and consist of letters, numbers, periods, dashes, and underscores only.
Fabric ID (1-4094)
Type an ID number from 1 through 4094.
Type a description of the Fabric profile, which will appear on the Manage Fabric Profiles page.
Max Login Sessions
Set the maximum number of FCoE initialization protocol (FIP) session logins permitted for the FCoE-FC gateway fabric.
The range is 128 through 2500. The default is 2500.
Click Add to select FCoE VLAN profiles to assign to the Fabric profile. Select the VLAN profiles from the list, then click OK.
To remove VLAN profiles, select one or more profiles, then click Remove.
Load Balance Algorithm
Set the load-balancing algorithm that the QFX Series uses to distribute FCoE sessions (FLOGI and FDISC sessions from the FCoE devices in the Ethernet network) among the NP_Port links to the FC switch.
Note: Changing the load-balancing algorithm when FCoE sessions are running forces the FCoE sessions to log out, and then log in again.
Select one of the following:
Disable Worldwide Name Verification
Select to Disable the fabric worldwide name (WWN) verification check in the fabric login accept message (FLOGI-ACC) for implicit FLOGIs.
If you enable this option, when a QFX Series NP_Port performs a FLOGI to the FC fabric, the QFX Series does not verify the fabric WWN in the FLOGI-ACC against the current fabric WWN.
Note: Disabling or enabling the fabric WWN verification check logs out all FCoE sessions.
Select to enable the specified 10-Gigabit Ethernet interface to trust Fibre Channel over Ethernet (FCoE) traffic. If an interface is connected to another switch such as an FCoE forwarder (FCF) or a transit switch, you can configure the interface as trusted so that the interface forwards FCoE traffic from the switch to the FCoE devices without installing FIP snooping filters.
Configure the specified local Fibre Channel fabric to trust FCoE traffic on all ports in the fabric. Changing the fabric ports from untrusted to trusted removes any existing FIP snooping filters from the ports. Changing the fabric ports from trusted to untrusted by removing the fcoe-trusted configuration from the fabric forces all of the FCoE sessions on those ports to log out so that when the ENodes and VN_Ports log in again, the switch can build the appropriate FIP snooping filters.
FCoE Mapped Address
Set the FCoE mapped address prefix (FC-MAP) value for the FCoE VLAN to match the FC switch (or FCoE forwarder) FC-MAP value for the FC fabric. The FC-MAP value is a unique MAC address prefix an FC switch uses to identify FCoE traffic for a given FC fabric (traffic on a particular FCoE VLAN).
Enter an FC-MAP value, which is a hexadecimal value preceded by “0x”. The range is 0x0EFC00 through 0x0EFCFF. The default value is 0xEFC00.
You can configure the FC-MAP value or use the default value. The FC switch provides the FC-MAP value to FCoE nodes (ENodes) in the FIP discovery advertisement message. If the EX Series switch or the QFX Series FCoE VLAN FC-MAP value does not match the FC switch FC-MAP value, neither device discovers the FC switch on that VLAN, and the ENodes on that VLAN cannot access the FC switch. The FC switch accepts only FCoE traffic that uses the correct FC-MAP value as part of the VN_Port MAC address.
When the QFX Series acts as an FCoE-FC gateway, the FC-MAP value for the gateway and the FCoE devices must match the FC switch FC-MAP value in order to communicate with the FC switch.
Note: Changing the FC-MAP value causes all logins to drop and forces the ENodes to log in again.
Keep Alive Interval
Set the global interval between periodic FIP keepalive advertisements, in milliseconds. The range is 250 through 90000 milliseconds. The default is 8000 milliseconds.
Set the global priority value associated with the switch FCF-MAC. CNAs use the priority value to determine the switch with which they will perform FIP FLOGI. The lower the value, the higher the priority. The switch advertises this value to the server ENodes on the FCoE network.
The range is 0 through 255. The default value is 128.
Max Sessions Per Node
Set the maximum number of FCoE login sessions (FLOGI plus FDISC) from a single ENode allowed on the gateway FC fabric (the fabric configured on the QFabric system). The maximum number of logins per ENode is 2000 sessions.
Note: A session is a FLOGI or FDISC login to the FC SAN fabric. Session does not refer to end-to-end storage sessions. There is no limit to the number of end-to-end storage sessions.
What to Do Next
Once the Fabric profile is created, you must assign the profile using the Assign Device Profile page to the required devices and then deploy the device configuration changes using the Deploy mode. To assign a Fabric profile, see Assigning a Fabric Profile to Devices and Ports. For information about deploying your configurations, see Deploying Configuration to Devices.
