MAC LAN specific codes

Table 1. MAC LAN specific codes
Code Meaning Explanation
2201 Ether_type (802.3) not valid Type field specified for ethernet was not valid. This is a completion code common to all primitives when Ethernet or IEEE 802.3 service is requested.
2202 Force_IMPL_enable (802.5) not valid This completion code is returned in response to a MAC_ENABLE request. A request to force a program load was not valid, possibly because the station has not allowed a remote program load.
2204 Initialize options (802.5) not valid The parameters requested to initialize the token-ring MAC layer are not valid.
2205 Open options (802.5) not valid Some of the parameters on the MAC_ENABLE request are not valid. The request is rejected.
2206 Rx_burst_size (802.5) not valid When data was being received or repeated, a sequence of four or more half-bit times were received without transition. This occurrence is not valid in the token-ring protocol.
2207 Group address not valid The group address specified in the MAC_ACTIVATE_SAP request is not valid. See the IBM® Token-Ring Network Architecture Reference for the format of a group address.
2208 Functional address (802.5) not valid This completion code applies only to token ring. The functional address specified in the MAC_ACTIVATE_SAP request is not valid or has the wrong format. See the IBM Token-Ring Network Architecture Reference for the format of the defined functional addresses.
2209 Group/logical address conflict The group address specified in the MAC_ACTIVATE_SAP request is in conflict with previously assigned MAC group addresses.
220A Function class conflict (802.5) The functional address specified in the MAC_ACTIVATE_SAP request is in conflict with previously assigned MAC functional addresses. See the IBM Token-Ring Network Architecture Reference for more information.
220B Duplicate MAC address The MAC address specified in the MAC_ENABLE request is already present in the ring. The request is rejected in order to prevent duplicate addresses.
220C Attribute type not valid This completion code is returned in response to a RTV_ATTRIB request. It indicates that the attribute type specified in the primitive is not valid.
220D Frame priority not valid This completion code is returned in response to a MAC_DATA request. It indicates that the requested priority of the frame is not valid.
220E Function class vector length (802.5) not valid This completion code is returned in response to a MAC_ACTIVATE_SAP request. It indicates that the length specified in the request for the function class vector is not valid.
220F Function class (802.5) not valid This completion code is returned in response to a MAC_ACTIVATE_SAP request. It indicates that a function class specified in the request was not valid. See the IBM Token-Ring Network Architecture Reference for the valid function classes.
2210 Destination address not valid This completion code is returned in response to a MAC_DATA request. It indicates that the destination address specified in the request is not valid.
2211 Frame type not valid This completion code is returned in response to a MAC_DATA request. It indicates that the frame type specified in the request is not valid. See the IBM Token-Ring Network Architecture Reference for a definition of the valid frame types.
2212 Frame control not valid This completion code is returned in response to a MAC_DATA request. It indicates that the frame control field specified in the request is not valid. See the IBM Token-Ring Network Architecture Reference for a definition of the valid frame control fields.
2213 Unauthorized access priority This completion code is returned in response to a MAC_DATA request. It indicates that the ring access priority requested for the frame is not valid. See the IBM Token-Ring Network Architecture Reference for a description of the priorities.
2214 Unauthorized MAC frame This completion code is returned in response to a MAC_DATA request. It indicates that the MAC frame requested to be transmitted is not authorized. See the IBM Token-Ring Network Architecture Reference for a list of the various MAC frames and the authorization needed to transmit them.
2215 Address not recognized This completion code is returned in response to a MAC_DATA request. It indicates that the MAC address specified in the frame was not recognized by any station on the local ring. Specifically, the address-recognized (A) bits were not set in the frame status field in the returned frame. See the IBM Token-Ring Network Architecture Reference for the format of the frame status field and the use of the A bits.
2216 Frame not copied This completion code is returned in response to a MAC_DATA request. It indicates that the MAC address specified in the frame was recognized by a station on the ring, but the station was unable to copy the frame. Specifically, the address-recognized (A) bit was set, but the frame-copied (C) bits were not set in the returned frame. See the IBM Token-Ring Network Architecture Reference for format of the frame status field and the use of the A and C bits.
2217 Ring status error (802.5) An error occurred on the ring during the processing of the request.
2218 Adapter check error An adapter check occurred when processing the corresponding request.
2219 Force IMPL enable (802.5) not valid A program load was requested but was invalid.
221A Open error (802.5) This completion code is returned in response to a MAC_ENABLE request. It indicates that an error occurred when attempting to enable the MAC layer.
221B Mode (802.3/4) not valid This completion code is returned in response to a MAC_ENABLE request. It indicates that a copy was requested but was not valid.
221C Net type (802.3) not valid This completion code indicates that the net type specified in the request is not valid.
221D In_ring_desired (802.4) not valid This completion code is returned in response to a MAC_ENABLE request. It indicates that the value specified for the In_ring_desired parameter is not one of the defined values.
221E Min_Post_Silence_ Preamble_Length (802.4) not valid This completion code is returned in response to a MAC_ENABLE request. It indicates that the value specified for the minimum time the station must idle after silence is not valid.
221F Maximum Number of SAPs exceeded This completion code is returned in response to a MAC_ACTIVATE_SAP request. It indicates that the maximum number of SAPs have been activated. The request is rejected.
2220 Field length not valid This completion code is returned in response to a MAC_DATA request. It indicates that the length of the routing information field is larger than this MAC can handle.
2221 MSDU length not valid This completion code is returned in response to a MAC_DATA request. It indicates that the value specified as the length of the MAC service data unit is not valid.
2222 Retries exhausted This completion code is returned in response to a request-with-response on a MAC_DATA request. It indicates that the protocol data unit (PDU) was transmitted such that the retries were exhausted, but no response was received. It is used in conjunction with LLC Type 3 service.
