Shazzam probe, port probes, and protocols

Port scanning is the first step in the Discovery process. The Shazzam probe performs port scanning, regardless of whether or not you use patterns for horizontal discovery. The following table lists the known ports and protocols used by Discovery.

Several port probes are available in the base system. Each port probe uses an IP Service, which is a record that tells Discovery which port to use for a specific protocol. Review this table before you block any ports with a firewall.
Caution: Make sure that you do not block any ports that Discovery needs.
Table 1. Default port probes and default IP services
Default port probe name Deafult classification Default IP Service, protocol and port
dns Process Classification [discovery_classy_proc] dns (port 53)
http HTTP Classification [discovery_classy_http] http (port 80) and https (port 443)
ip_phone SNMP Classification [discovery_classy_snmp] sip (port 5060)
osx Scan Results Application Classifier [discovery_classy_scan_app] afp (port 548)
printer Scan Results Application Classifier [discovery_classy_scan_app] hp-pdl-datastr (port 9100) and printer (port 515)
slp Process Classification [discovery_classy_proc] slp (port 427)
snmp SNMP Classification [discovery_classy_snmp] snmp (port 161)
ssh UNIX Classification [discovery_classy_unix] ssh (port 22)
vmapp Application Classification [discovery_classy_appl] vmapp_https (port 5480) and vmapp6_https (port 9443)
wbem CIM Classification [discovery_classy_cim] wbem_https (port 5989)
winrm Windows Classification [discovery_classy_windows] winrm (port 5985) and winrm_ssl (port 5986)
wins Process Classification [discovery_classy_proc] ms-nb-ns (port 137)
wmi Windows Classification [discovery_classy_windows] epmap (port 135)

This table shows you other common ports and protocols that Discovery uses.
