A
MIB
is
a
database
of
network
management
information
that
is
used
and
maintained
by
a
network
management
protocol,
such
as
SNMP.
The
value
of
a
MIB
object
can
be
changed
or
retrieved
using
SNMP
commands,
usually
through
a
network
management
system.
The PPPoE Session Count MIB uses two SNMP traps that generate notification messages when a PPPoE session-count threshold
is reached on any PVC or on the router. The PPPoE session-count thresholds can be configured using the
sessions
max
limit and
pppoe
max-sessions commands. You can also set per-MAC session and IWF limits for a PPPoE session, per-MAC throttle rate limit for a PPPoE session,
per-VLAN session configuration limit, per-VLAN throttle rate limit, per-VC session configuration limit, and per-VC throttle
rate limit configuration limit.
The table below describes the objects and tables supported by the PPPoE Session-Count MIB. For a complete description of
the MIB, see the PPPoE Sessions Management MIB file CISCO-PPPOE-MIB.my, available through Cisco.com at the following URL:
