Table 133: Supported MIBs Fields
Field Description
Name The RFC number if applicable and the name of the MIB.
Description The RFC title or MIB description.
Access Control Group
Use the Access Control Group page to configure SNMP access control groups. These SNMP groups
allow network managers to assign different levels of authorization and access rights to specific device
features and their attributes. The SNMP group can be referenced by the SNMP community to provide
security and context for agents receiving requests and initiating traps as well as for management
systems and their tasks. An SNMP agent will not respond to a request from a management system
outside of its configured group, but an agent can be a member of multiple groups at the same time to
allow communication with SNMP managers from different groups. Several default SNMP groups are
preconfigured on the system.
To access this page, click System > Advanced Configuration > SNMP > Access Control Group in the
navigation menu.
Use the buttons to perform the following tasks:
•
To add an SNMP group, click Add and specify the desired setting.
•
To remove one or more SNMP groups, select each entry to delete and click Remove . You must
confirm the action before the entry is deleted.
Table 134: Access Control Group Fields
Field Description
Group Name The name that identifies the SNMP group.
Context Name The SNMP context associated with the SNMP group and its views. A user or a
management application specifies the context name to get the performance
information from the MIB objects associated with that context name. The
Context EngineID identifies the SNMP entity that should process the request (the
physical router), and the Context Name tells the agent in which context it should
search for the objects requested by the user or the management application.
SNMP Version The SNMP version associated with the group.
Security Level The security level associated with the group, which is one of the following:
•
No Auth No Priv – No authentication and no data encryption (no security).
This is the only Security Level available for SNMPv1 and SNMPv2 groups.
•
Auth No Priv – Authentication, but no data encryption. With this security
level, users send SNMP messages that use an
MD5 key/password for
authentication, but not a DES key/password for encryption.
•
Auth Priv – Authentication and data encryption. With this security level,
users send an MD5 key/password for authentication and a DES key/password
for encryption.
