edge-loop-detection vlan

Enables edge-loop detection (ELD) on a port and VLAN.

Synopsis

edge-loop-detection vlan vlan-ID

no edge-loop-detection vlan vlan-ID

Operands

vlan vlan-ID

Specifies a VLAN. (Refer to the Usage Guidelines.)t.

Defaults

Edge-loop detection is disabled.

Command Modes

Interface subtype configuration mode

Description

Use this command to enable edge-loop detection for a specific VLAN ID.

Usage Guidelines

Use the VLAN parameter to specify a VLAN and port on which to enable edge-loop detection.
The port must be a member of the specified VLAN or the command returns an error.

On the Brocade VDX family of switches, VLANs are treated as interfaces from a configuration point
of view. By default, all the DCB ports are assigned to VLAN 1 (VLAN ID equals 1). Valid VLAN IDs
are as follows:

•

On Brocade VDX 8770 switches: 1 through 4086 for 802.1Q VLANs (VLAN IDs 4087
through 4095 are reserved on these switches), and 4096 through 8191 for service or
transport VFs in a Virtual Fabrics context.

•

On all other Brocade VDX switches: 1 through 3962 for 802.1Q VLANs (VLAN IDs 3963
through 4095 are reserved on these switches), and 4096 through 8191 for service or
transport VFs in a Virtual Fabrics context.

This command applies to Brocade VCS Fabric mode only.

This functionality detects Layer 2 loops only.

Enter no edge-loop-detection vlan vlan_id to disable edge-loop detection on the specified VLAN.

Examples

To enable edge-loop detection on VLAN 10 for a specific 10-gigabit Ethernet interface port:

switch(config)# interface tengigabitethernet 1/0/7

switch(conf-if-te-1/0/7)# edge-loop-detection vlan 10

To disable edge-loop detection on a specific 1-gigabit Ethernet interface port and a VLAN whose ID
is 20:

switch(config)# interface gigabitethernet 170/1/9

switch(conf-if-gi-170/1/9)# no edge-loop-detection vlan 20
