Chapter 11: Simple Network Management Protocol (SNMP) Commands
204
Overview
The commands in this chapter are used to set the three Get, Set and Trap
community strings for Simple Network Management Protocol (SNMP).
These strings can be used to manage the media converter with an
SNMPv1 or SNMPv2c application and for trap verification.
The commands here are also used to set the IP addresses of up to four
trap receivers. Traps are signals sent to management workstations by the
unit to indicate the occurrences of specific operating events on the device,
and are commonly used to monitor the activities of the unit.
SNMP Guidelines
Here are the guidelines for remote SNMPv1 and SNMPv2c management:
ˆ The management module must have an IP configuration. For
instructions, refer to Chapter 3, “IP Configuration Commands” on page
47.
ˆ The 10/100/1000Base-T Management port on the management
module must be connected to a network device, such as a Fast
Ethernet or Gigabit switch. Remote SNMP management sessions are
conducted through that port.
ˆ The remote workstation with the SNMP program must be a member of
the same network as the management module or have access to it
through Layer 3 routing devices.
ˆ If the management module and remote workstation are on different
networks, the IP configuration on the management module must
include a default gateway that specifies the IP address of the first hop
to reaching the workstation. For instructions, refer to Chapter 3, “IP
Configuration Commands” on page 47.
ˆ You must load the Allied Telesis private MIBs into your SNMP program
on your workstation. The MIBs are available from the Allied Telesis
web site at www.alliedtelesis.com.
Trap Events
Activities that generate SNMP traps are listed below:
ˆ Module has been installed or removed
ˆ Port link status is offline or online
ˆ Port link status is RX (receive) SML or TX (transmit) SML
ˆ Port operational mode is changed to Missing Link or SML
ˆ Port operational mode is changed to OAM Bypass, OAM visible, or link
test
ˆ TFTP session is opened or closed
ˆ XMODEM session is opened or closed
ˆ Telnet session is opened or closed
