Table 20: show dhcp server statistics Output Fields
Field DescriptionField Name
Number of packets discarded by the extended DHCP local server because of errors. Only nonzero
statistics appear in the Packets dropped output. When all of the Packets dropped statistics are 0
(zero), only the Total field appears.
• Total—Total number of packets discarded by the extended DHCP local server
• Authentication—Number of packets discarded because they could not be authenticated
• Bad hardware address—Number of packets discarded because an invalid hardware address was
specified
• Bad opcode—Number of packets discarded because an invalid operation code was specified
• Bad options—Number of packets discarded because invalid options were specified
• Dynamic profile—Number of packets discarded due to dynamic profile information
• Invalid server address—Number of packets discarded because an invalid server address was specified
• Lease Time Violation—Number of packets discarded because of a lease time violation
• No available addresses—Number of packets discarded because there were no addresses available
for assignment
• No interface match—Number of packets discarded because they did not belong to a configured
interface
• No routing instance match—Number of packets discarded because they did not belong to a configured
routing instance
• No valid local address—Number of packets discarded because there was no valid local address
• Packet too short—Number of packets discarded because they were too short
• Read error—Number of packets discarded because of a system read error
• Send error—Number of packets that the extended DHCP local server could not send
Packets dropped
Number of DHCP messages received.
• BOOTREQUEST—Number of BOOTP protocol data units (PDUs) received
• DHCPDECLINE—Number of DHCP PDUs of type DECLINE received
• DHCPDISCOVER—Number of DHCP PDUs of type DISCOVER received
• DHCPINFORM—Number of DHCP PDUs of type INFORM received
• DHCPRELEASE—Number of DHCP PDUs of type RELEASE received
• DHCPREQUEST—Number of DHCP PDUs of type REQUEST received
• DHCPLEASEQUERY—Number of DHCP leasequery messages received.
• DHCPBULKLEASEQUERY—Number of DHCP bulk leasequery messages received.
• DHCPRENEW—Number of DHCP renew messages received; subset of DHCPREQUEST counter.
