ACCULINK 316x DSU/CSU
Interface Group – Output Counters
(objects ifEntry 16 to ifEntry 21)
The objects used to collect statistics on the data
transmitted by an interface apply only to the COM port
and the MODEM port when the port is configured as the
SNMP management link. For interfaces that are not
configured as the SNMP management link, these statistics
are not provided and an error status is returned if access is
attempted. The objects used to collect output statistics are
listed below:
ifOutOctets (ifEntry 16)
ifOutUcastPkts (ifEntry 17)
ifOutNUcastPkts (ifEntry 18)
ifOutDiscards (ifEntry 19)
ifOutErrors (ifEntry 20)
ifOutQLen (ifEntry 21)
IP Group, MIB II
The IP Group Objects are supported by the T1
DSU/CSU for the MODEM port and the COM port when
the port is configured as the SNMP management link. All
of the objects in the IP Group other than the IP Address
Translation table are fully supported. The IP Group
objects are not supported for the T1 interfaces and
synchronous data ports. The following sections provide
clarification for objects contained in the IP Group when it
is not clear how the object definition in MIB II is related
to the DSU/CSU.
IP Group – "ipForwarding" Object (ip 1)
This object specifies whether the unit is acting as an IP
gateway in respect to the forwarding of a datagram
received by, but not addressed to, this unit. Only the
following value is supported by the DSU/CSU.
not-forwarding(2) – The unit is not acting as a
gateway.
IP Group – "ipRoutingTable" Object (ip 21)
The routing table used by the DSU/CSU is supported
as a read-only table. Entries in this table may not be added
or deleted.
E-6
IP Group – "ipNetToMediaTable"
Object (ip 22)
This table is not supported.
ICMP Group, MIB II
The ICMP Group objects are fully supported by the T1
DSU/CSU for the MODEM port and the COM port when
the port is configured as the SNMP management link. The
ICMP Group objects are not supported for the T1
interfaces and synchronous data ports.
UDP Group, MIB II
The UDP Group objects are fully supported by the T1
DSU/CSU for the MODEM port and the COM port when
the port is configured as the SNMP management link. The
UDP Group objects are not supported for the T1 interfaces
and synchronous data ports.
Transmission Group, MIB II
Objects in the Transmission Group are supported on
the Network and DTE Drop/Insert T1 interfaces and the
synchronous data ports. The Transmission Group objects
are not supported on the COM and MODEM ports. The
objects in the Transmission Group are not defined within
MIB II but rather through other Internet-standard MIB
definitions. The following two Transmission Group
objects are supported by the T1 DSU/CSU.
ds1 (transmission 18) – The transmission object
supported on the T1 interfaces.
rs232 (transmission 33) – The transmission object
supported on the synchronous data ports.
The "ds1" transmission object is defined by the
DS1/E1 MIB. The rs232 transmission object is defined by
the RS-232-like MIB.
