Configuring SNMP Values
SNMP (Simple Network Management Protocol) is a protocol defined by the
Internet community. All TCP/IP-type traffic is encapsulated in Ethernet
frames. The EMM supports SNMP by responding to SNMP requests and
generating SNMP traps. An EMM acts as an agent in an SNMP- managed
environment, enabling you to configure your EMM and all modules in the
concentrator through SNMP. It has a community table that can contain up
to 10 IP addresses.
An IP Address entry in a community table may have one of the following
attributes assigned:
– read-only allows the specified IP address to read SNMP
variables via the SNMP GET command
– read-write allows the specified IP address to read and
write SNMP variables via the SNMP GET and SNMP SET
commands, respectively
– trap sends a trap to the specified IP address when an
SNMP variable is changed
– read-trap allows the specified IP address to read SNMP
variables and receive traps
– all (read-write, and trap) allows the specified IP address
to read SNMP variables, change the variables via the SNMP
SET command and receive traps whenever an SNMP
variable is changed.
– oldtrap access means that the IP Address you specify will
receive alerts from the EMM based on the 3Com MIB I.
– read_oldtrap access means that the IP Address you
specify can display information about the EMM and it will
receive alerts based on the 3Com MIB I.
– oldall access means that the IP Address you specify has
read_write and trap access to the EMM based on the
3Com MIB I.
