Network Environment: A 3550EMI switch is divided into three VLANs. vlan2 is the network where the server is located and is named server. The IP address segment t-[/[Xm1S3 is 192.168.2.0, subnet mask: 255.255.255.0, Gateway: 192.168.2.1 the Domain Server is windows 2000 advanceserver and serves as a DNS server. The IP address is 192.168.2.10, vlan3 is the network where client 1 is located, the IP address segment is 192.168.3.0, The subnet mask is 255.2
