Errata ID: 4820

Section 3.1.7 says:

   Network speeds are increasing.  The range of ifSpeed is limited to
   reporting a maximum speed of (2**31)-1 bits/second, or approximately
   2.2Gbs.  SONET defines an OC-48 interface, which is defined at
   operating at 48 times 51 Mbs, which is a speed in excess of 2.4Gbs.
   Thus, ifSpeed is insufficient for the future, and this memo defines
   an additional object: ifHighSpeed.

It should say:

   Network speeds are increasing.  The range of ifSpeed is limited to
   reporting a maximum speed of (2**32)-1 bits/second, or approximately
   4.3Gbs.  SONET defines an OC-48 interface, which is defined at
   operating at 48 times 51 Mbs, which is a speed in excess of 2.4Gbs.
   Thus, ifSpeed is insufficient for the future, and this memo defines
   an additional object: ifHighSpeed.

Notes:

RFC 3635, in section 3.2.8 quotes RFC2863 as if it were using the correct 4.3Gbps value: "For these speeds, ifSpeed should report a maximum unsigned 32-bit value of 4,294,967,295 as specified in [RFC2863]."
