Chapter 26: MAC Address-based VLANs
296 Section VI: Virtual LANs
Egress ports cannot be part of a static or LACP trunk.
Since this type of VLAN does not support tagged packets, it is not
suitable in environments where a network device, such as a network
server, needs to be shared between multiple VLANs.
Ports 49 and 50 on the AT-9448Ts/XP switch cannot be designated as
egress ports of a MAC address-based VLAN.
SFP ports 45 to 48 on the AT-9448T/SP switch cannot be designated
as egress ports of a MAC address-based VLAN.
