Command Reference Guide
debug ip dhcp relay
Use the debug ip dhcp relay command to activate debug messages associated with Dynamic Host
Configuration Protocol version 4 (DHCPv4) relay 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 relay
debug ip dhcp relay 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 18.2
Release 18.3
Release R10.1.0
Functional Notes
The debug ip dhcp relay command activates debug messages to provide information on DHCPv4 relay
activity in AOS. The AOS DHCPv4 relay capability allows AOS to relay DHCPv4 messages to a configured
destination 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:
>enable
60000CRG0-35E
Optional. Displays debug information for the specified VPN routing and
forwarding (VRF) instance.
