Description: A table of station addresses known at an individual port. This table is designed to reduce the number of SNMP GETNEXT requests. This is done by packing many values into an octet string. (The maximum size frame should be used to return the result.) The instance returned for a GETNEXT is the value that identifies the last 'row' in the octet string. When the table is completely retrieved with one or more GETNEXTs, duplicate entries may be present, and entries may be skipped if the table is changing while being retrieved.
