The Network-Id-Name Attribute is utilized by implementations of
IEEE-802.1X to specify the name of a Network-Id
Unlike the IEEE 802.11 SSID (which is a maximum of 32 octets in
length), the NID-Name may be up to 253 octets in length.
Consequently, if the MAC address is included within the Called-
Station-Id Attribute, it is possible that there will not be enough
remaining space to encode the NID-Name as well. Therefore, when
used with IEEE 802.1X , the Called-Station-Id
Attribute SHOULD contain only the MAC address, with the Network-
Id-Name Attribute used to transmit the NID-Name. The Network-Id-
Name Attribute MUST NOT be used to encode the IEEE 802.11 SSID; as
noted in , the Called-Station-Id Attribute is used for
this purpose.Zero or one Network-Id-Name Attribute is permitted within an
Access-Request, Access-Challenge, Access-Accept or Accounting-
Request packet. When included within an Access-Request packet,
the Network-Id-Name Attribute represents a hint of the NID-Name to
which the Supplicant should be granted access. When included
within an Access-Accept packet, the Network-Id-Name Attribute
represents the NID-Name to which the Supplicant is to be granted
access. When included within an Accounting-Request packet, the
Network-Id-Name Attribute represents the NID-Name to which the
Supplicant has been granted access.
A summary of the Network-Id-Name Attribute format is shown below.

The String field is one or more octets, containing a NID-Name.
For details, see . A robust implementation SHOULD
support the field as undistinguished octets.
