Configuring SNMPv3 Groups
Use the Administration > SNMP (Configure Group) page to add an SNMPv3 group which can be used to set the access policy for its
assigned users, restricting them to specific read, write, and notify views. You can use the pre-defined default groups or create new
groups to map a set of SNMP users to SNMP views.
The following table lists the options on this page:
FIG. 242

Administration - SNMP Options
Group Name
The name of the SNMP group to which the user is assigned. (Range: 1-32 characters)
Security Model
The user security model; SNMP v1, v2c or v3.
Security Level
The following security levels are only used for the groups assigned to the SNMP security model:
• noAuthNoPriv - There is no authentication or encryption used in SNMP communications. (This is
the default security level.)
• AuthNoPriv - SNMP communications use authentication, but the data is not encrypted.
• AuthPriv - SNMP communications use both authentication and encryption.

RFC1493 Traps
newRoot
1.3.6.1.2.1.17.0.1
The newRoot trap indicates that the sending agent has
become the new root of the Spanning Tree; the trap is sent
by a bridge soon after its election as the new root, e.g.,
upon expiration of the Topology Change Timer immediately
subsequent to its election.
topologyChange
1.3.6.1.2.1.17.0.2
A topologyChange trap is sent by a bridge when any of its
configured ports transitions from the Learning state to the
Forwarding state, or from the Forwarding state to the
Discarding state. The trap is not sent if a newRoot trap is
sent for the same transition.
SNMPv2 Traps
coldStart
1.3.6.1.6.3.1.1.5.1
A coldStart trap signifies that the SNMPv2 entity, acting in
an agent role, is reinitializing itself and that its
configuration may have been altered.
warmStart
1.3.6.1.6.3.1.1.5.2
A warmStart trap signifies that the SNMPv2 entity, acting
in an agent role, is reinitializing itself such that its
configuration is unaltered.
linkDown*
1.3.6.1.6.3.1.1.5.3
A linkDown trap signifies that the SNMP entity, acting in an
agent role, has detected that the ifOperStatus object for
one of its communication links is about to enter the down
state from some other state (but not from the notPresent
state). This other state is indicated by the included value of
ifOperStatus.
