enable bootprelay

enable bootprelay {{vlan} [vlan_name] | {{vr} vr_name} | all [{vr} vr_name]}

Description

Enables the BOOTP Relay function on one or all VLANs for the specified VR or VRF.

Syntax Description


`vlan_name`	Specifies a single VLAN on which to enable the BOOTP Relay feature.
`vr_name`	Specifies a single VR or VRF on which to enable the BOOTP Relay feature. If not specified, VR or VRF of current command context is used.
all	Specifies that BOOTP Relay is to be enabled for all VLANs on the specified VR or VRF.

Default

The BOOTP Relay function is disabled on all VLANs and VRs.

If not specified, VR of current command context is used.

Usage Guidelines

Because VLAN names are unique on the switch, you can specify only a VLAN name (and omit the VR name) to enable BOOTP Relay on a particular VLAN. When you enable BOOTP Relay on a VR or VRF, BOOTP Relay is enabled on all VLANs for that VR. If you enter the command without specifying a VLAN or a VR, the functionality is enabled for all VLANs in the current VR context.

Note

If DHCP/BOOTP Relay is enabled on a per VLAN basis, make sure it is enabled on both the client-side and server-side VLANs.

Example

The following example enables the forwarding of BOOTP requests for all VLANs in the current VR context:

enable bootprelay

You can use either of the following commands to enable the forwarding of BOOTP requests for VLAN client1:

enable bootprelay "client1"
enable bootprelay vlan "client1"

You can use any one of the following commands to enable the forwarding of BOOTP requests for all VLANs on VR zone3:

enable bootprelay zone3
enable bootprelay vr zone3
enable bootprelay all zone3
enable bootprelay all vr zone3
