MAC address table
The MAC address table shows the MAC address details of devices connected to Sophos Switch, including the port and VLAN to which they're connected.
You can also filter and block MAC addresses to prevent them from sending traffic to Sophos Switch on certain ports and VLANs.
Static MAC address
Static MAC addresses are MAC addresses you enter manually into the MAC address table. Static MAC addresses are kept in the MAC address table until you manually remove them.
To add a static MAC address, click Add, enter the MAC address, Port, and VID, then click Apply.
To edit a static MAC address entry, click Edit.
To delete a static MAC address entry, click Delete.
Dynamic MAC address
Dynamic MAC addresses are MAC addresses that Sophos Switch has learned from the src mac add
field of Address Resolution Protocol (ARP) packets received by Sophos Switch.
To add a dynamic MAC address to the static MAC address table, click Move to static.
To add a dynamic MAC address to the MAC filter table, click Move to filter.
MAC aging time
The MAC aging time is the time, in seconds, a dynamic MAC address remains valid. When the MAC aging time reaches the limit, Sophos Switch checks if the MAC address is still connected and, if not, removes the disconnected MAC addresses from the MAC address table.
To set the MAC aging time, enter a value from 10 to 630 and click Apply.
MAC filters
You can allow MAC addresses to connect to specified VLANs while blocking them from others on the MAC filters tab.
To add a MAC address to the MAC filters list, click Add, enter the VID and the MAC address, and click Apply.
To remove a MAC address from the MAC filters list, select the MAC address and click Delete.
MAC blocking
The MAC blocking tab lets you block all traffic from specific MAC addresses on all VLANs. When you add a dynamic MAC address to the MAC blocking list, it's deleted from the Dynamic MAC address table and won't be added back.
You can turn MAC blocking on or off from the Global settings tab.
The Blocking list tab shows all blocked MAC addresses and the VLANs on which they're blocked.
To block a MAC address, click Add. Enter the MAC address and click Apply.
To remove a MAC address from the blocked list, select the MAC address and click Delete.
