A. B. C. D.A
Switches have an efficient method of managing stale MAC addresses, which is an aging timer. For MX Series devices, the aging timer defaults to a value of 300 seconds. This value can be changed using the global-mac-table-aging-time parameter under the [edit protocols l2-learning] hierarchy.
On an MX Series device, the MAC table stores the MAC addresses learned from the Ethernet frames received on its interfaces. The entries in the MAC table can age out after a period of time, depending on the timeout interval configured. The MAC table aging time is used to configure the timeout interval for entries in the MAC table.
The correct answer is A. global-mac-table-aging-time.
A. global-mac-table-aging-time: This parameter is used to configure the timeout interval for entries in the MAC table. The default value is 300 seconds, and the maximum value is 1,800 seconds.
B. global-mac-limit: This parameter is used to configure the maximum number of MAC addresses that can be learned on the device. The default value is 64,000.
C. switch-mac-table-aging-time: This parameter is used to configure the timeout interval for entries in the MAC table on a specific switch. This is only applicable for devices that have multiple switches, such as the EX Series switches.
D. switch-mac-limit: This parameter is used to configure the maximum number of MAC addresses that can be learned on a specific switch. This is only applicable for devices that have multiple switches, such as the EX Series switches.
In conclusion, the parameter used to configure the timeout interval for entries in the MAC table on an MX Series device is A. global-mac-table-aging-time.
