PMP> Interfaces MIB, RFC 1213 and 1573 Comparison

Comparison of the IF MIB (RFC 1573) to the interfaces group of RFC 1213:

This is my action item for the PMP Teleconference tomorrow. This
comparision is to be used to determine the impact of requiring
conformance to RFC 1573 in the Printer MIB. I hope this helps in
providing some order to this MIB.

Note: RFC 1573 is an extension to the interfaces group of RFC 1213 and
is not a replacement for RFC 1213.

Four objects in RFC 1213 are deprecated:

ifInNUcastPkts (Non-unicast packets received)
ifOutNUcastPkts (Non-unicast packets transmitted)
ifOutQLen (Output queue size)
ifSpecific (A reference to another MIB with more info)

RFC 1573 contains four tables and 29 objects:

ifXTable:

-- The following four objects are replacements for ifInNUcastPkts
-- and ifOutNUcastPkts.
ifInMulticastPkts
ifInBroadcastPkts
ifOutMulticastPkts
ifOutBroadcastPkts

-- 64 bit counter versions - Mandatory only if ifSpeed is greater than
-- 650 Mbps. 32 bit counter versions are Mandatory if ifSpeed is less
-- than 20 Mbps. A mixture of 32 and 64 bit counters are used between
-- 20 Mbps and 650 Mbps.
-- RFC 1573 has defined five groups that are mutually exclusive.
-- Many of these objects are members of multiple groups.
ifHCInOctets
ifHCInUcastPkts
ifHCInMulticastPkts
ifHCInBroadcastPkts
ifHCOutOctets
ifHCOutUcastPkts
ifHCOutMulticastPkts
ifHCOutBroadcastPkts

-- Mandatory objects for character oriented network interfaces or which
-- transmit using a fixed-length transmission unit.
ifName
ifLinkUpDownTrapEnable (conformance requires read-only)
ifHighSpeed (a version of ifSpeed in Mbps)
ifPromiscuousMode (conformance requires read-only)
ifConnectorPresent

ifStackTable: (Mandatory)
ifStackHigherLayer
ifStackLowerLayer
ifStackStatus

ifTestTable: (Optional)
ifTestId
ifTestStatus
ifTestType
ifTestResult
ifTestCode
ifTestOwner

ifRcvAddressTable: (The applicablity of this group is to be defined
by the media-specific MIB)
ifRcvAddressAddress
ifRcvAddressStatus
ifRcvAddressType
