clcMacLimitEnable
Module: CISCO-L2-CONTROL-MIB
OID (symbolic): CISCO-L2-CONTROL-MIB::clcMacLimitEnable
OID (numeric): 1.3.6.1.4.1.9.9.313.1.1.1
Node type: OBJECT-TYPE
Type: TruthValue
Access: read-write
Description: 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 or interface or interface-VLAN pair in the forwarding tables for a network device. It is possible that one VLAN or one interface or interface-VLAN pair can exhaust all available MAC entries because of Denial-of-Service and cause users' traffic on the other VLANS or interfaces flooded. To prevent this situation, the MAC limit for each VLAN or interface or interface-VLAN pair is needed. The major function of this feature is to protect the layer 2 forwarding table.
What is clcMacLimitEnable?
This read-write object globally enables or disables the MAC address limit feature, which caps the number of learned MAC addresses per VLAN, interface, or interface-VLAN pair in the device's forwarding tables. Turning it on activates enforcement of MAC address count limits network-wide.
Examples
Walk all instances (SNMPv2c):
