Logging DHCP Packet Information
The JUNOSe software enables you to collect and log DHCP packet information for
all JUNOSe DHCP access models on a per-interface basis. To log packets for a specific
DHCP application, you enable DHCP packet logging on the interface that serves the
application. JUNOSe software supports per-interface DHCP packet logging on a
maximum of 16 interfaces. Per-interface DHCP packet logging is disabled by default.
You can specify which packets are logged—receive, transmit, or all. You can optionally
assign low or high priority to the logged packets. Packets are assigned a low priority
by default, which does not interfere with router DHCP packet processing. The logged
packets are output to the dhcpCapture event logging category.
You can configure per-interface DHCP packet logging on statically configured and
dynamically created IP interfaces. However, configuration information for dynamic
interface configurations is lost after a cold restart. Both static and dynamic interface
configuration information is maintained after a warm restart.
You use the ip dhcp-capture command with the following keywords to enable DHCP
packet logging for all DHCP applications on the interface.
■
Use the receive , transmit , and all keywords to specify the type of DHCP packets
that is logged.
■
Use the optional priority keyword to assign a low or high priority to logged
packets. By default, logged packets have a low priority and do not interfere with
the router’s DHCP packet processing.
You can specify DHCP packet logging on a maximum of 16 interfaces.

To enable DHCP packet logging:
host1(config-if)# ip dhcp-capture all
