17.4.1
The MIB counters memory map
hardware-maintained counters reside. The counters are divided into two groups:
The transmit and receive RMON counters are independent, which ensures accurate network statistics when
operating in full duplex mode.
The included IEEE counters support the mandatory and recommended counter packages defined in
Section 5 of ANSI/IEEE Std. 802.3 (1998 edition). The FEC supports IEEE Basic Package objects, but
these do not require counters in the MIB block. In addition, some of the recommended package objects
supported do not require MIB counters. Counters for transmit and receive full duplex flow control frames
are also included.

RMON counters include the Ethernet statistics counters defined in RFC 1757
A counter is included to count truncated frames since only frame lengths up to 2047 bytes are
supported
