cisco-l2-control-mib.mib object
Introduction
Most network devices and programs ship with so-called MIB files to describe the parameters and meanings (i.e.: friendly names) which are available for monitoring via SNMP.
ActiveXperts Network Monitor 2025 can import vendor-specific MIB files, so it can be used to monitor specific OID's (Object Identifiers).
This way, you can monitor your devices, computers, etc. by selecting your relevant OID's by name.
ActiveXperts Network Monitor 2025 can import MIB file cisco-l2-control-mib and use it to monitor vendor specific OID's.

Object view of cisco-l2-control-mib:
| Scalar Object |
| clcMacLimitEnable |
.1.3.6.1.4.1.9.9.313.1.1.1 |
|
This object is to enable or disable the limit of number
of MAC addresses function globally.
MAC limit function is to try to control the number of MAC
addresses for each VLAN in the forwarding tables for a
network device. It is possible that one VLAN can exhaust
all available MAC entries because of Denial-of-Service
and cause users' traffic on the other VLANS flooded. To
prevent this situation, the MAC limit for each VLAN is
needed. The major function of this feature is to protect
the layer 2 forwarding table.
|
| clcMaxMacLimitDefault |
.1.3.6.1.4.1.9.9.313.1.1.2 |
|
The global default value for limit number of MAC addresses
in the system.
If clcMacLimitEnable is false(2), this object may not be
writable.
|
| clcMacLimitExceededActionDefault |
.1.3.6.1.4.1.9.9.313.1.1.3 |
|
The global default action to be taken by the system
when the number of VLAN MAC addresses in the forwarding
table has exceeded the number of MAC address limit
for the VLAN.
If clcMacLimitEnable is false(2), this object may not be
writable.
|
| clcMacLimitExceedNotifOption |
.1.3.6.1.4.1.9.9.313.1.1.4 |
|
This MIB object provides the choices of generating MAC limit
exceeded notification to the users.
When the system detects the current learned number of MAC
addresses in the forwarding table which has exceeded the limit
number of MAC addresses, the system will generate the
following notifications.
syslog(1) : An syslog message will be generated to users.
snmpNotif(2) : An SNMP notification message will be generated
to users.
both(3) : Both a syslog message and an SNMP notification
message will be generated to users.
If clcMacLimitEnable is false(2), this object may not be
writable.
|
| clcMacLimitNotifEnable |
.1.3.6.1.4.1.9.9.313.1.1.5 |
|
The MIB object controls generation of SNMP notification
for MAC Limit feature.
When this object is true(1), generation of
clcVlanMacLimitNotif is enabled. When this object is
false(2), generation of clcVlanMacLimitNotif is disabled.

vlanMaxMacLimit(0) : indicates that the value of
clcVlanMaxMacLimit is based on the value of
clcMaxMacLimitDefault if this bit is set.

clcVlanMacLimitExceededAction is based on the
value of clcMacLimitExceededActionDefault if this
bit is set.
