Description

Displays the enabled/disabled configuration of BOOTP relay on one or all This command is available on the ExtremeSwitching X440-G2, X450-G2, X460-G2, X465, X590, X620, X670-G2, X690, X695, X870, 5320, 5420, 5520 series switches.s for the specified VR.

Syntax Description


bootprelay	BOOTP Relay Configuration
ipv4	DHCPv4 BOOTP Relay service.
ipv6	DHCPv6 BOOTP Relay service.
vlan	VLAN
`vlan_name`	Specifies a single VLAN for which to display BOOTP relay configuration information.
vr	Use a specific virtual router name.
`vr_name`	Specifies a single VR for which to display BOOTP relay configuration information.

Default

IPv4.

If a VR is not specified, this command displays the specified VLANs for the current VR context.

Usage Guidelines

Note

ExtremeXOS DHCPv6 supports three options: OPTION_RELAY_MSG (9), OPTION_INTERFACE_ID (18), and OPTION_REMOTE_ID (37).

Note

It is mandatory to configure BOOTP Relay v6 Agents. The packets are not forwarded if the v6 agents are not configured.

Example

The following example displays the BOOTP relay configuration for all VLANs on the VR-Default virtual router:

# show bootprelay configuration vr "VR-Default"
BOOTP Relay : Enabled on virtual router "VR-Default"
VLAN                                    BOOTP Relay
--------------------------------        -----------
Default                                 Disabled
client1                                 Enabled
serv                                    Enabled

The following example displays the BOOTP relay configuration for all VLANs in the current VR context:

# show bootprelay configuration
BOOTP Relay : Enabled on virtual router "VR-Default"
VLAN                                    BOOTP Relay
--------------------------------        -----------
Default                                 Disabled
client1                                 Disabled
serv                                    Disabled

The following example displays the BOOTP relay configuration for VLAN client1:

# show bootprelay configuration vlan "client1"
BOOTP Relay : Enabled on virtual router "VR-Default"
VLAN                                    BOOTP Relay
--------------------------------        -----------
client1                                 Disabled

The following example displays the BOOTP relay configuration for IPv6:

# show bootprelay configuration ipv6
DHCPv6 BOOTP Relay : Enabled on virtual router "VR-Default" 
VLAN                                     DHCPv6 BOOTP Relay
--------------------------------          ------------------
Default                                        Enabled

The following example displays the BOOTP relay configuration for IPv6 when vr is disabled:

# show bootprelay configuration ipv6
DHCPv6 BOOTP Relay : Disabled on virtual router "VR-Default"

The following example shows DHCP/BOOTP relay configuration that is disabled for the VR, but enabled on some VLANs:

# show bootprelay configuration 
DHCPv4 BOOTP Relay : Disabled on virtual router "VR-Default", but enabled on some VLANs.
    Include Secondary    : Disabled
    BOOTP Relay Servers  : 
    DHCP Relay Agent Information Option: Disabled
    DHCP Relay Agent Information Check : Disabled
    DHCP Relay Agent Information Policy: Replace
    DHCP Relay Agent Source VLAN       : ltep

History

This command was first available in ExtremeXOS 12.4.2.

Information about DHCP/BOOTP relay being disabled for the VR, but enabled on some VLANs was added in ExtremeXOS 22.5.

VLAN to use as the source IP address in the BOOTRrelay packet information was added in 30.7.
