F. SNMP MIB Objects
3160-A2-GB24-10 March 2001
F-13
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.
