IP Group – “ipRouteProto” Object
(ipRouteEntry 9)
This object is a read-only object and may have the
following values in the E1 DSU/CSU.
•
other(1) – Temporary route added by IP.
•
local(2) – Route added or modified as a result of
user configuration via the front panel.
•
netmgmt(3) – Route added or modified by means of
an SNMP set.
•
icmp(4) – Route added or modified by Internet
Control Management Protocol (ICMP).
•
rip(8) – Route added or modified by the Routing
Information Protocol (RIP) or similar proprietary
protocol.
IP Group – “ipRouteAge” Object
(ipRouteEntry 10)
This object is implemented as a read-only object in the
E1 DSU/CSU. In the E1 DSU/CSU, it reflects the value of
the route’s time-to-live (in seconds). When displayed, 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 E1
DSU/CSU.
UDP Group, MIB II
The User Datagram Protocol (UDP) Group objects are
fully supported by the E1 DSU/CSU.
Transmission Group, MIB II
Objects in the transmission group are supported on the
network and DTE Drop/Insert interfaces, the COM 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 E1 DSU/CSU.
•
ds1 (transmission 18) – The transmission object
supported on the E1 interfaces.
•
rs232 (transmission 33) – The transmission object
supported on the synchronous data ports, COM
port, and AUX 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 E1 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)
•

•
snmpInGetResponses (snmp 18)
•
snmpInTraps (snmp19)
•
snmpOutGetRequests (snmp 25)
•
