+-- media where ARP is in use, the translation table is\r
+-- equivalent to the ARP cache; or, on an X.25 network where\r

+-- part of the Internet standardization process, the\r
+-- definitions are accordingly elevated and a new object\r
+-- identifier, under the transmission group is defined. By\r
+-- convention, the name assigned is:\r
+--\r
+-- type OBJECT IDENTIFIER ::= { transmission number }\r
+--\r
+-- where "type" is the symbolic value used for the media in\r
+-- the ifType column of the ifTable object, and "number" is\r
+-- the actual integer value corresponding to the symbol.\r
+\r
+\r
+-- the SNMP group\r
+\r
+-- Implementation of the SNMP group is mandatory for all\r
+-- systems which support an SNMP protocol entity. Some of\r
+-- the objects defined below will be zero-valued in those\r
+-- SNMP implementations that are optimized to support only\r
+-- those functions specific to either a management agent or\r
+-- a management station. In particular, it should be\r
+-- observed that the objects below refer to an SNMP entity,\r
+-- and there may be several SNMP entities residing on a\r
+-- managed node (e.g., if the node is hosting acting as\r
+-- a management station).\r
