Description: The reason for failure to validate the SNMP request. nmAccessTableRestriction(1) indicates that the requesting network management station (NMS) does not have appropriate permission to perform the SNMP request, because it either does not match an ip address in the docsDevNmAccessTable, or the community string in the SNMP request did not match the community string in docsDevNmAccessTable for the requesting NMS, or the docsDevNmAccessControl value specified in the docsDevNmAccessTable for this NMS was not sufficient to allow access for the SNMP request type (either 'get' or 'set'), or finally the SNMP request from this NMS is not accepted on the interface (ethernet or CATV) that the request was received. noWriteAccessToMibVar(2) indicates that an SNMP set request was received for a mib variable whose write access control is set. other(3) indicates an nonspecific error.
