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.
