Parameter Valid Ranges/Remarks
FECN to EFCI
Specifies the method used to convert the forward explicit congestion notification (FECN)
information to the congestion indication (CI) bit, or the explicit forward congestion
indication (EFCI) bit, to be inserted in the ATM cells
• Always 0: Ignores the FECN bit received from the Frame Relay equipment connected
to the data port, and always set the EFCI bit to 0
• Conv: In the receive path, the EFCI/CI bit is derived from the received FECN bit

3.9 Viewing and Modifying SNMP Community
SNMP delimits management domains by defining communities. Each community
is identified by a name, which is an alphanumeric string of up to 255 characters
defined by the user.
The 5620 Model Descriptor for LA-110 SNMP agent defines strings of up to
10 characters (case sensitive, numeric and alphabetical).
Any SNMP entity (both managed entities and management stations) is assigned a
community name by its user. In parallel, the user defines a list of the communities
for each SNMP entity that are authorized to communicate with the entity, and the
access rights associated with each community (this is the SNMP community name
table of the entity).
In general, SNMP agents support two types of access rights:
• Read: The SNMP agent accepts and processes only SNMP getRequest and
getNextRequest PDUs with matching community names.
• Write: The SNMP agent accepts and processes all the SNMP commands
received from a management station with matching community names.
To view and modify SNMP community:
1. In the LA-110 Node Draw, select the system (as described in Selecting the
System), and from the menu bar, select
Object > Configure > SNMP Community.
