Model 5399 Remote Access Concentrator Network Administrator's Guide for UNIX
The SNMP agent authenticates an SNMP request through the use of
access permissions. The config file format for SNMP defines the IP
address and access modes. Security is set by defining community strings
that have None, Read-only, or Read-Write access to the MIB variables.
The format is shown below:
snmp community <string> <IP address> <access>
You can use a wild card (*) to define the IP address. Using a wild card
allows anybody with that community string to have access.
You can specify up to ten SNMP community names in the gateway
section of the configuration file, but each community requires a separate
line. The 5399 RAC adds these communities to the SNMP agent's
community table. The syntax is:
snmp community name
Defining Trap Hosts and Traps
The 5399 RAC employs two methods for defining the host addresses it uses
when generating SNMP trap messages.
• The first method defines up to ten static trap hosts in the
configuration file using the SNMP trap host syntax.
• The second method loads the trap hosts (if any) from the
configuration file into the Trap Host Table (i.e., the
anxTrapHostTable objects in the proprietary MIB). You can
modify this table by adding or deleting trap hosts. However, the
changes you make directly through the MIB will be lost when
the 5399 RAC reboots. If you want your changes to be
permanent, you must use the configuration file.
