Unless indicated otherwise, the values described here during IP address reuse are internally
provisioned or set by the process itself and not by manual administration.
• Routers in Use - if no responses are received from the routers indicated in the configuration
parameter ROUTER (set using DHCP Option 3 or by a local administrative procedure), and if
REUSE = 1, then ROUTER_IN_USE will be set to REUSE_ROUTER_IN_USE. With the
exception of the ROUTER configuration parameter, the other router-related parameters are
internally set system values.
• VLAN Check - During the VLAN check, if a reset is to be done and VLAN_IN_USE is not
zero, VLAN_IN_USE will be added to VLANLIST if it is not already on VLANLIST.
The VLAN detection process described in Automatically detecting a VLAN on page 52 is
followed if tagging is off or if tagging is on and L2QVLAN is > 0, and if REUSETIME > 0, and
if REUSE_IPADD is not “0.0.0.0”. If VLANTEST expires, the value of VLAN_IN_USE is
added to VLANLIST if it is not already on VLANLIST.
If a DHCPOFFER is not received within REUSETIME seconds, or if a DHCPOFFER is received
that contains a value of L2QVLAN that is on VLANLIST, REUSE will be set to 1, IPADD will be set
to the value of REUSE_IPADD, NETMASK will be set to the value of REUSE_NETMASK,
ROUTER will be set to the value of REUSE_ROUTERS, and if the value of REUSE_TAGGING is
1, 802.1Q tagging will be turned on with a VLAN ID equal to the value of L2QVLAN_INIT, DHCP
will then enter the “extended” REBINDING state, and operation will proceed as normal.
After a successful registration, the following system values are set:
• REUSE_IPADD will be set to the value of IPADD
• REUSE_NETMASK will be set to the value of NETMASK
• REUSE_ROUTERS will be set to the value of ROUTER
• REUSE_ROUTER_IN_USE will be set to the value of ROUTER_IN_USE
• REUSE_TAGGING will be set to the value of TAGGING
• L2QVLAN_INIT will be set to the value of VLAN_IN_USE
• The MIB object endptVLANLIST will be set to the value of VLANLIST and then the value of
VLANLIST will be set to null.
