December 1996
3170-A2-GB20-20
IP Group
Supported.
ICMP Group
Supported.
TCP Group
Not supported since the TCP
protocol is not supported by the
E1 DSU/CSU.
UDP Group
Supported.
EGP Group
Not supported since the EGP
protocol is not supported by the
E1 DSU/CSU.
Transmission
Group
Supported on the E1 interfaces
using the DS1/E1 MIB. Supported
on the synchronous data ports
using the RS-232-like MIB.
Supported on the COM and AUX
ports using the RS-232-like MIB.
SNMP Group
Supported.
System Group, MIB II
The System Group objects are fully supported by the
E1 DSU/CSU. The following sections provide
clarification for objects contained in the System Group
where it is not otherwise clear how the object definition in
MIB II is related to the E1 DSU/CSU. Objects not
mentioned are supported as stated in the MIB.
System Group – “sysDescr” Object (system 1)
This object provides the full name and version
identification for the system hardware and software. This
object displays the following string:
E1 DSU/CSU; model xxxx-xx-xxx; S/W Release:
yy.yy.yy; H/W CCA1: z z z z-z z z; H/W CCA2: z z z z-z z z;
Serial number: sssssss.
Where:
xxxx-xx-xxx represents the full model
number of the unit.
yy.yy.yy represents the software revision
number of the unit.
z z z z-z z z represents the hardware
revision numbers of the unit.
sssssss represents the serial number of
the unit.
System Group – “sysObjectID” Object
(system 2)
This object provides the authoritative identification of
the network management subsystem contained in the unit.
This object displays the following object identifier:
3172
1.3.6.1.4.1.74.1.14.2.2.5
3174
1.3.6.1.4.1.74.1.14.2.2.6
System Group – “sysServices” Object
(system 7)
This object provides a value which indicates the set of
services that are potentially offered by the E1 DSU/CSU.
Only the following values are supported by the E1
DSU/CSU.
•
physical(1) – Layer 1 functionality for all
interfaces.
•
datalink/subnetwork(2) – Layer 2 functionality
(SLIP, PPP) for the COM and AUX ports.
•
internet(4) – Layer 3 functionality (IP) for all
management links.
•
end-to-end(8) – Layer 4 functionality (UDP) for all
management links.
Therefore, set this object to 15 (the sum
of 1 + 2 + 4 + 8).
Interface Group, MIB II
The Interface Group consists of an object indicating the
number of interfaces supported by the unit and an
interface table containing an entry for each interface. The
E1 DSU/CSU provides an entry in the interface table for
the network interface, the DTE Drop/Insert interface, each
of the synchronous data ports, the COM port, and the
AUX port, if they apply. The following sections provide
clarification for objects contained in the Interface Group
where it is not clear how the object definition in MIB II is
related to the E1 DSU/CSU.
Interface Group – “ifNumber” Object
(interfaces 1)
This variable contains the maximum number of MIB II
supported interfaces possible across the 31xx Series
product line (9). This is different from the MIB
description, which is defined as the number of interfaces
on the particular device. This change allows the use of the
same ifIndexes across all 31xx Series models.
