Section 12, pg.25 says:

[[ DESCRIPTION clause for pwFcsRetentionCfg OBJECT-TYPE ]]

         "The local configuration of Frame Check Sequence (FCS)
          retention for this PW.  FCS retention can be configured for
          PW types High-Level Data Link Control (HDLC), Point-to-Point
          Protocol (PPP), and Ethernet only.  If the implementation
|         does not support FCS retention, an error MUST be reported in
          pwFcsRetentionStatus.  This object MAY be changed only if
          the PW is not active."

It should say:

         "The local configuration of Frame Check Sequence (FCS)
          retention for this PW.  FCS retention can be configured for
          PW types High-Level Data Link Control (HDLC), Point-to-Point
          Protocol (PPP), and Ethernet only.  If this object is set to
          fcsRetentionEnable(2) and the implementation does not support
          the FCS retention for this PW, an error MUST be indicated by
          setting pwFcsRetentionStatus to localFcsRetentionCfgErr(4).
          This object can be changed only if the PW is not active." 

Notes:

Rationale:

The original DESCRIPTION indicated unconditional signaling of an error, whether
the activation of unsupported FCS retention is requested or not.
This is contrary to the DESCRIPTION for pwFcsRetentionStatus.
