Configure FA Management on a Port or MLT

Use this procedure to configure a management I-SID on a Fabric Attach (FA)-enabled port or MLT.

To configure an FA management I-SID for Auto-sense-enabled ports, see Configure a Management I-SID for Auto-sense Fabric Attach Proxy Switches.

Before you begin

Ensure that the port or MLT is enabled for FA.

About this task

This command applies to all traffic sent or received on a port or MLT, carrying the VLAN ID specified using the c-vid parameter. This parameter is optional.

Depending on whether the c-vid parameter is specified or not, the behavior is as follows:

  • If you specify the c-vid parameter, the FA Server transmits this VLAN ID as the management VLAN in the FA Element TLV. A client or proxy receiving this TLV uses this VLAN-ID for management traffic on the FA Server uplink.

  • If you do not specify the c-vid parameter, the FA Server transmits a management VLAN with a VLAN ID value of 4095 in the FA Element TLV. A client or proxy receiving this TLV uses untagged traffic for network management on the FA Server uplink.

An FA management I-SID can have a platform VLAN associated with it. For Layer 3 support on the management I-SID, you must create a platform VLAN by port and associate the platform VLAN with the management I-SID. The C-VID can be of the same value or of a different value than that of the platform VLAN.

If the management I-SID matches one of the FA Switched UNI (ELAN) I-SIDs (as displayed by the command show i-sid elan), then the platform VLAN is automatically associated with the FA-enabled interface (port or MLT).

Procedure

  1. Enter Interface Configuration mode:

    enable

    configure terminal

    interface GigabitEthernet {slot/port[/sub-port][-slot/port[/sub-port]][,...]} or interface mlt <1-512>

    Note

    Note

    If the platform supports channelization and the port is channelized, you must also specify the sub-port in the format slot/port/sub-port.

  2. Configure the FA management I-SID:

    fa management i-sid <i-sid><c-vid>

    Important

    Important

    If you do not specify a C-VID value, the port or MLT is untagged.

  3. Verify configuration of FA management on the port or MLT, using the following commands:
    • show i—sid <i-sid>

    • show interfaces gigabitEthernet i-sid [{slot/port[/sub-port] [-slot/port[/sub-port]] [,...]}]

    • show mlt i-sid [<1–512>]

Examples

Configure FA management on port 1/2:

Switch:1>enable
Switch:1#configure terminal
Enter configuration commands, one per line.  End with CNTL/Z.
Switch:1(config)#interface gigabitethernet 1/2
Switch:1(config-if)#fa management i-sid 101 c-vid 101

Configure FA management on MLT 10.

Switch:1>enable
Switch:1#configure terminal
Enter configuration commands, one per line.  End with CNTL/Z.
Switch:1(config)#interface mlt 10
Switch:1(config-mlt)#fa management i-sid 101

Verify configuration of FA management on the MLT. Because the C-VID is not specified, the MLT displays as untagged.

Switch:1(config-mlt)#show i-sid 101

Variable Definitions

The following table defines parameters for the fa management command.

Variable

Value

i-sid <i-sid>

Specifies the management I-SID. Different hardware platforms support different customer I-SID ranges. To see the available range for the switch, use the CLI Help.

<c-vid>

Specifies the customer VLAN ID. Different hardware platforms support different customer VLAN ID ranges. Use the CLI Help to see the available range for the switch.

Important:

If you do not specify a C-VID value, the port or MLT is untagged.
