3.18 Embedded SNMP Agent
The embedded SNMP agent, if installed, for Loop-V 4200 offers standard RFC 1213 MIB II and RFC 1406
DS1 MIB as well as Loop Telecom's enterprise MIB. Network manager can use any SNMP compatible
network management system such as Sun Connect's Sun Net Manager and Hewlett-Packard's HP Open
View to monitor and control Loop-V 4200 series. This enables user to integrate WAN equipment
management with LAN SNMP network management systems. The embedded SNMP agent also includes
Telnet implementation to allow user to access Loop-V 4200 terminal interface from any workstation in the
network.
Figure 3- 2 SNMP Connection
Before SNMP is enabled, make sure the IP address for Loop-V 4200 is configured correctly and the
communication parameters match the Terminal server port. The IP address is set in the System
Configuration screen.
Once the SNMP agent is activated, user can verify whether the Loop-V 4200 is running successfully by using
ping command to check if Loop-V 4200 series is responding or not. e.g.
$ ping 192.1.100.45
192.1.100.45 is alive
Please refer to each respective SNMP manager operation instruction to incorporate the Loop-V 4200 series
enterprise MIB to the system.
Telnet capability comes with embedded SNMP agent. Once SNMP agent is running, user can use telnet
program that is simulated a VT100 to access Loop-V 4200 command screen. The most popular Telnet utility
in the public domain is provided by NCSA. Only one user at a time can use telnet connection. It is
recommended to set the CONSOLE port running at the highest speed to reduce the jittery output on terminal.
The Loop-V 4200 can run reliably at 38.4K bps.
3.19 Inband Management
Management of the Loop-V 4200 can be done through the LCD panel, the console port, the optional SNMP
port or through the optional Router card with Subnet management (SNMC). Using the Router card,
management of a local as well as remote Loop products (up to 32 inband management capable devices per
card) is available.
A Network Management System (NMS) is connected to the Router card’s Ethernet port. Using the TSI map,
one channel is mapped to the unit’s internal inband management port (HDLC port), and additional channels
are mapped to T1/E1 time slots. These time slots must be sent to the remote unit, which does not require the
Router card, which will map the incoming time slot to it’s internal inband management port (HDLC port in the
case of another 4200-9).
