You can see packets about BOOTPS, DHCP, ARP and ICMP using the following com-
mand.
Command
debug packet {interface INTERFACE | port
PORTS} protocol {bootps | dhcp | arp | icmp}
{src-ip A.B.C.D | dest-ip A.B.C.D}
debug packet {interface INTERFACE | port
PORTS} host {src-ip A.B.C.D | dest-ip A.B.C.D}
{src-port <1-65535> | dest-port <1-65535>}
debug packet {interface INTERFACE | port
PORTS} host {src-port <1-65535> | dest-port
<1-65535>}
debug packet {interface INTERFACE | port
PORTS} multicast [src-ip A.B.C.D | dest-ip
A.B.C.D]

-l
from tcpdump.
-n
Do not translate all address (e.g. port, host address)
-N
When output host name, do not print domain.
Do not run packet-matching code optimizer. This option is used to find bug in opti-
-O
mizer
-p
Interface is not remained in promiscuous mode
-q
Reduce output quantity of protocol information. Therefore, output line is shorter.
-S
