 |`-sl` |Wait extra time for response (also known as slow link delay) |Use this parameter to double the time that PortQry waits for a response from a UDP port before PortQry determines that the port is NOT LISTENING or that it's FILTERED. When you query over slow or unreliable network links, the normal wait time may be too short to receive a response. |
 |`-nr` |Skip reverse name lookup |<ul><li>By default, when you use `-n` to specify an IP address for the target computer, PortQry does a reverse name lookup to resolve the IP address to a name. This process may be time-consuming, especially if PortQry can't resolve the IP address. Use `-nr` to skip this step of the query.</li><li>If you use `-n` to specify a computer or domain name, PortQry ignores `-nr`. |
 |`-sp <port_number>` |Query from a specific source port |<ul><li>The \<*port_number*> value represents the port that PortQry uses to send the query.</li><li>PortQry can't use a port that another process is already using. If the port that you specify is already in use, PortQry returns the following error message:<br/>Cannot use specified source port.<br/>Port is already in use.<br/>Specify a port that is not in use and run the command again.</li><li>In the following cases, PortQry uses the specified port for the first test of the query, but not the second test: <ul><li>RPC (TCP and UDP ports 135)</li><li>LDAP (UDP port 389)</li><li>NetBIOS Adapter status query (UDP port 137)</li></ul>In these cases, PortQry uses an ephemeral port for the second test. When this occurs, PortQry records "Using ephemeral source port" in its output.</li><li>If the computer where PortQry is installed also runs the IPSec policy agent, UDP port 500 may not be available to use as a source port. To temporarily turn off the IPSec policy agent so that you can use port 500, run `net stop PolicyAgent`. When you have finished testing, run `net start PolicyAgent`.</li></ul> |
-|`-cn !<community_name>!` |Query an SMTP community |<ul><li>The \<*community_name*> value represents the name of the SNMP community to query. You must delimit this value by using exclamation points, as shown in the left column.</li><li>If the SNMP service is not listening on the target port, PortQry ignores `-cn`.</li><li>The default community name is `public`.</li></ul>  |

 |`-q` |Run PortQry in quiet mode |<ul><li>When you use `-q`, PortQry suppresses all screen output except for error messages.</li><li>To see output other than error messages, use `-q` together with `-l`.
