IP Group – “ipRouteAge” Object

(ipRouteEntry 10)

This object is implemented as a read-only object in the
DSU/CSU. In the DSU/CSU, it reflects the value of the
route’s time-to-live (in seconds). When displays, a value
of 999 represents a route that is retained permanently. For
temporary routes, the ipRouteAge object decrements over
time. All routes added via an SNMP set of the
ipRouteTable are considered permanent routes. These
routes do not age, but will remain unless deleted via
SNMP.

ICMP Group, MIB II

The ICMP Group objects are fully supported by the
DSU/CSU.

TCP Group, MIB II

The TCP Group objects are fully supported by the
DSU/CSU, with the exception of the tcpConnState object,
which will be read-only.

UDP Group, MIB II

The User Datagram Protocol (UDP) Group objects are
fully supported by the DSU/CSU.

Transmission Group, MIB II

Objects in the transmission group are supported on the
network and DTE Drop/Insert (DSX-1) interfaces, the
COM port, the MODEM port, the AUX port, and the
synchronous data 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
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, COM
port, AUX port, and MODEM port.
The “ds1” transmission object is defined by the
DS1/E1 MIB. The rs232 transmission object is defined by
the RS-232-like MIB.

SNMP Group, MIB II

The SNMP Group objects that apply to a management
agent are fully supported by the DSU/CSU. The following
objects apply only to an NMS and return a zero value if
accessed.
•snmpInTooBigs (snmp 8)
•snmpInNoSuchNames (snmp 9)
•snmpInBadValues (snmp 10)
•snmpInReadOnlys (snmp 11)
•snmpInGenErrs (snmp 12)
•snmpInGetResponses (snmp 18)
•snmpInTraps (snmp19)
•snmpOutGetRequests (snmp 25)
•snmpOutGetNexts (snmp 26)
•snmpOutSetRequests (snmp 27)
DS1/E1 MIB (RFC 1406)
The “ds1” object defined by RFC 1406 is supported for
both the network and DTE Drop/Insert (DSX-1)
interfaces. The DS1 Near End Group and DS1 Fractional
Group are supported for both interfaces. The DS1 Far End
Group is not supported.

Near End Group, DS1/E1 MIB

The DS1 Near End Group consists of the following
four tables:
•DS1 Configuration
•DS1 Current
•DS1 Interval
•DS1 Total
