agentPortSecurityDynamicLimit
Module: EdgeSwitch-PORTSECURITY-PRIVATE-MIB
OID (symbolic): EdgeSwitch-PORTSECURITY-PRIVATE-MIB::agentPortSecurityDynamicLimit
OID (numeric): 1.3.6.1.4.1.4413.1.1.20.1.2.1.2
Node type: OBJECT-TYPE
Type: Unsigned32
Access: read-write
Description: This variable signifies the limit of dynamically locked MAC addresses allowed on a specific port.
What is agentPortSecurityDynamicLimit?
This read-write value sets the maximum number of dynamically learned MAC addresses allowed to be locked on this port, defaulting to 4096. An admin lowers this on an access port to cap how many different devices can be auto-learned, preventing a MAC-flooding attack from exhausting the port's address table. For example, setting this to 3 on a port feeding a small IP phone and PC combo restricts it to just three learned addresses.
Examples
