Description: The dynamic entry count is the max number of dynamic entries allowed on the port.
What is me1200IpSourceGuardInterfaceDynamicEntryCount?
This value sets the maximum number of dynamically learned IP source guard bindings, typically learned via DHCP snooping, that are allowed on a given port. Admins tune it to cap how many distinct IP/MAC pairs a port can automatically register, preventing a single port from exhausting the binding table or being used to spoof many source addresses. For example, an admin might set this to 1 on a single-host access port but raise it to 50 on a port feeding an unmanaged hub with many DHCP clients.
