Configure Aging Function of Static MAC Address
Configuration Condition
Before configuring the aging function of the static MAC address, first complete the following task:
- Enable the port security function
Enable Aging Function of Static MAC Address
To detect whether the terminal of the effective entry of the MAC rule or IP rule is online, the user can enable the aging function of the static MAC address. After the aging function of the static MAC address and if it is detected that the terminal is offline, the effective entry of the terminal is deleted so that the chip resources can be released.
