Any Network Manager running SNMP can manage the BlackDiamond, provided the
MIB is installed correctly on the management station. In addition to private MIBs, the
BlackDiamond supports the standard MIBs listed in Table 2-6.
The IEEE Bridge MIB dot1dTpPortEntry PortInDiscards and dot1dBasePortEntry
counters are not incremented.

ETTINGS
The following SNMP parameters can be configured on the system:
• Authorized trap receivers — An authorized trap receiver can be one or more
network management stations on your network. The BlackDiamond sends SNMP
traps to all trap receivers. You can have a maximum of six trap receivers configured
for each BlackDiamond. Entries in this list can be created, modified, and deleted
using the RMON2 trapDestTable MIB variable, as described in RFC 2021.
• Authorized managers — An authorized manager can be either a single network
management station, or a range of addresses (for example, a complete subnet)
specified by a prefix and a mask. The BlackDiamond can have a maximum of 32
authorized managers.
• Community strings — The community strings allow a simple method of
authentication between the system and the remote Network Manager. There are two
types of community strings on the BlackDiamond. Read community strings provide
read-only access to the system. The default read-only community string is public.
