54.....Avocent® Universal Management Gateway Appliance Installer/User Guide
The lease bindings tell you which IP addresses have been dynamically assigned to targets. It
displays the range, start and end times, MACaddress, hostname, port number and target device
type. The lease bindings can only be cleared by deleting the dynamic range they were issued from
and restarting the DHCPserver. Lease times are measured in days.
NOTE: Only one range may operate on a private interface.
Advanced settings
Within the appliance shell, the /etc/dhcpd.conf file can be edited to add DHCPscope options, such
as option 6 (DNSserver) or option 15 (DOMAIN name).
Discovery
You can discover service processors from a variety of IPranges within routed access of the
appliance. You can specify up to 20 IP address ranges either for automatic or manual discovery.
Discovered service processors are displayed in the SP Management list.
In order to discover a service processor, the SP must have an IP address belonging to the
discovery range and a username and password pre-populated in the Default Users tab. The SP
must be a type supported by the appliance as listed in the firmware release notes.
Whether performing a discovery, import or manually adding an SP, the appliance will always
perform a capabilities discovery to determine the licensed feature set of each SPin order to display
session buttons or control capabilities appropriate for what the SPwill support. For example, an
HPiLO without an advanced license does not support vKVM. When added to the appliance, the
capability discovery will recognize the license in the iLOand will disable the vKVMsession button.
CAUTION: The appliance requires most SP types to have IPMIenabled in order to be discovered or
managed. Some SPs will have IPMIdisabled by default, for example, iDRAC7. If the SPis physically
connected behind the appliance and cannot be discovered or added due to an IPMIproblem, you may
manually add the SPusing the generic profile. Then launch an SPAccess browser session to the SPand
correct the IPMIproblem. Then delete the generic SPand add it using the appropriate SPprofile.
Physical discovery
The appliance has a DHCP service active by default running on the priv virtual interface.
SPs physically connected to the appliance and configured as DHCPclients will be issued an IPand
then queried for discovery. ADHCPscope is, by default, assigned only to the priv virtual interface
and associated physical ports. The spm and kvm virtual interfaces do not have addresses assigned
to them by default. To assign DHCP ranges to the spm and kvm virtual interfaces to discover and
