+.SH DESCRIPTION
+.RB "The " rpcctl " command displays information collected in the SunRPC sysfs files about the system's SunRPC objects.
+.P
+.SS rpcctl client \fR- \fBCommands operating on RPC clients
+.IP "\fBshow \fR[ \fICLIENT \fR] \fB(default)"
+Show detailed information about the RPC clients on this system.
+If \fICLIENT \fRwas provided, then only show information about a single RPC client.
+.P
+.SS rpcctl switch \fR- \fBCommands operating on groups of transports
+.IP "\fBset \fISWITCH \fBdstaddr \fINEWADDR"
+Change the destination address of all transports in the \fISWITCH \fRto \fINEWADDR\fR.
+\fINEWADDR \fRcan be an IP address, DNS name, or anything else resolvable by \fBgethostbyname\fR(3).
+.IP "\fBshow \fR[ \fISWITCH \fR] \fB(default)"
+Show detailed information about groups of transports on this system.
+If \fISWITCH \fRwas provided, then only show information about a single transport group.
+.P
+.SS rpcctl xprt \fR- \fBCommands operating on individual transports
+.IP "\fBremove \fIXPRT"
+Removes the specified \fIXPRT \fRfrom the system.
+Note that "main" transports cannot be removed.
+.P
+.IP "\fBset \fIXPRT \fBdstaddr \fINEWADDR"
+Change the destination address of the specified \fIXPRT \fR to \fINEWADDR\fR.
+\fINEWADDR \fRcan be an IP address, DNS name, or anything else resolvable by \fBgethostbyname\fR(3).
+.P
+.IP "\fBset \fIXPRT \fBoffline"
+Sets the specified \fIXPRT\fR's state to offline.
+.P
+.IP "\fBset \fIXPRT \fBonline"
+Sets the specified \fIXPRT\fR's state to online.
+.IP "\fBshow \fR[ \fIXPRT \fR] \fB(default)"
+Show detailed information about this system's transports.
+If \fIXPRT \fRwas provided, then only show information about a single transport.
+.SH EXAMPLES
+.IP "\fBrpcctl switch show switch-2"
+Show details about the RPC switch named "switch-2".
+.IP "\fBrpcctl xprt remove xprt-4"
+Remove the xprt named "xprt-4" from the system.
+.IP "\fBrpcctl xprt set xprt-3 dstaddr https://linux-nfs.org
