+.SH DESCRIPTION
+The \fBip ioam\fR command is used to configure IPv6 In-situ OAM (IOAM6)
+internal parameters, namely IOAM namespaces and schemas.
+.PP
+Those parameters also include the mapping between an IOAM namespace and an IOAM
+schema.
+
+.SH EXAMPLES
+.PP
+.SS Configure an IOAM namespace (ID = 1) with both data (32 bits) and wide data (64 bits)
+.nf
+# ip ioam namespace add 1 data 0xdeadbeef wide 0xcafec0caf00dc0de
+.PP
+.SS Link an existing IOAM schema (ID = 7) to an existing IOAM namespace (ID = 1)
+.nf
+# ip ioam namespace set 1 schema 7
+.SH SEE ALSO
