swL2IpMacBindingPortStopLearningThreshold
Module: DES3550-L2MGMT-MIB
OID (symbolic): DES3550-L2MGMT-MIB::swL2IpMacBindingPortStopLearningThreshold
OID (numeric): 1.3.6.1.4.1.171.11.64.2.2.7.1.1.7
Node type: OBJECT-TYPE
Type: INTEGER
Access: read-write
Description: This object indicates the threshold to stop learning new MAC addresses on the specified port. When the number of blocked entries exceeds the threshold, the port will stop learning new addresses. The packet with a new address will be dropped. Note: When 0 is set on the specified port, it means no limit.
What is swL2IpMacBindingPortStopLearningThreshold?
Sets how many blocked (violating) entries this port tolerates before it stops learning any new MAC addresses and begins dropping packets from new sources; 0 disables the limit. It's a brute-force defense against a port being hammered with spoofed addresses.
