Command Reference Guide
debug ip dhcp server
Use the debug ip dhcp server command to activate debug messages associated with Dynamic Host
Configuration Protocol version 4 (DHCPv4) server operation in AOS. Debug messages are displayed (real
time) to the terminal (or Telnet) screen. Use the no form of this command to disable the debug messages.
Variations of this command include:
debug ip dhcp server
debug ip dhcp server vrf <name>
Turning on a large amount of debug information can adversely affect the performance of
your unit.
Syntax Description
vrf <name>
Default Values
By default, all debug messages in AOS are disabled.
Command History

Release R10.1.0
Functional Notes
The debug ip dhcp server command activates debug messages to provide information on DHCPv4
server activity in AOS. The AOS DHCPv4 server capability allows AOS to dynamically assign IPv4
addresses to hosts on the network.
VRF on AOS products allows a single physical router to be partitioned into multiple virtual routers. Each
router instance has its own route table and interface assignments. Beginning with Release 16.1, all AOS
routers supporting multiple VRF instances (multi-VRF) have an unnamed default VRF instance regardless
of whether multi-VRF is configured. Therefore, executing the abovementioned commands without
specifying a VRF will only affect the default unnamed VRF.
Usage Examples
The following example activates debug messages associated with DHCPv4 server activity only on the
default VRF instance:
60000CRG0-35E
Optional. Displays debug information for the specified VPN routing and
forwarding (VRF) instance.
Command was introduced.
Command was expanded to include the vrf parameter.
Command syntax was changed to remove the hyphen (from dhcp-server)

Command syntax was changed to remove the hyphen (from dhcp-server)
