Interactions with DHCP

Disabling Layer 3 functionality and DHCP are mutually exclusive, with DHCP taking precedence

over disable layer3 on a VLAN. The following interactions occur:

• If the disable layer3 command is executed when DHCP is already configured, no disabling

of the VLAN occurs. This error message displays: “Layer 3 cannot be disabled on a VLAN

that has DHCP enabled.”

• From the CLI: If disable layer3 is configured already, and an attempt is made to configure

DHCP, DHCP takes precedence and will be set. The warning message displays: “Layer 3 has

also been enabled on this VLAN since it is required for DHCP.”

• From the CLI: When disabling a range of VLAN IDs, this warning message displays: “Layer

3 will not be disabled for any LANs that have DHCP enabled.”

• From SNMP: If the disable layer3 command is executed when DHCP is already

configured, no disabling of the VLAN occurs. An INCONSISTENT_VALUE error is returned.

• From SNMP: If disable layer3 is configured already, and an attempt is made to configure

DHCP, DHCP takes precedence and will be set.

Ports not specifically assigned to a VLAN are automatically in the default VLAN.
