IP Group – “ipRouteProto” Object
(ipRouteEntry 9)
This object is a read-only object and may have the
following values in the E1 NTU.
•
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 NTU. In the E1 NTU, 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
NTU.
UDP Group, MIB II
The User Datagram Protocol (UDP) Group objects are
fully supported by the E1 NTU.
Transmission Group, MIB II
Objects in the transmission group are supported on the
network and G.703 DTE 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 NTU.
•
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 NTU. The following
objects apply only to an NMS and return a zero value if
accessed.
