What is tnIPSourceGuardDynamicMacAddress?
tnIPSourceGuardDynamicMacAddress is the MAC address associated with a dynamically-learned IP Source Guard binding, typically populated automatically via DHCP snooping and paired with the entry's port, VLAN, and source IP address. An admin reads this table to audit which client MAC-to-IP bindings the switch has currently learned and is enforcing on a given port. For example, an admin might see this object return 00:1A:2B:3C:4D:5F for a dynamically-learned binding on port 5, confirming which device's DHCP-assigned address is currently trusted there.
