for a specific protocol on an interface
tcpdump
tcpdump -i logical interface name proto protocol
The following example command shows OSPF traffic:

tcpdump -i logical interface name port TCP/UDP
application port
The following example command shows telnet traffic:
tcpdump -i eth-s1p1c0 port telnet
The following example command also shows telnet traffic:
tcpdump -i eth-s1p1c0 port 23

UDP application port
The following example shows all BOOTP/DHCP traffic:
tcpdump -i eth-s2p1c0 udp port 68
