Dell EMC SmartFabric OS10 User Guide Release 10.5.0

Media Access Control

All Ethernet switching ports maintain media access control (MAC) address tables. Each physical device in your network contains a MAC address. OS10 devices automatically enter learned MAC addresses as dynamic entries in the MAC address table.

Learned MAC address entries are subject to aging. Set the aging timer to zero (0) to disable MAC aging. For any dynamic entry, if no packet arrives on the device with the MAC address as the source or destination address within the timer period, the address is removed from the table.

• Enter an aging time (in seconds) in CONFIGURATION mode, from 0 to 1000000, default 1800.
