•
Device A connects to the marketing department through Ethernet 1/0/1 and connects to the trunk
port Ethernet 1/0/1 of Device B through the trunk port Ethernet 1/0/2; Device C connects to the
server through Ethernet 1/0/2 and connects to the trunk port Ethernet 1/0/2 of Device B through
the trunk port Ethernet 1/0/1. Device A supports egress port configuration.
