12 2-1-3-3. Switch Cascading T opology • T akes the Dela y T i me into Account Theoretically , the switch partitions the collision domain for each port in swit ch cascading that you may up-link the swit ches unlimitedly . In practice, the network extension (cascading levels & overall diam eter) must follow the constraint of the IEEE 802.
13 Case1: All switch ports are in the same local area network. Every port can acce ss each other (See Fig. 2-3). If VLAN is enabled and configured, each node in the network that can communicate each other di rectly is bounded in the same VLAN area. Here VLAN area is defin ed by what VLAN you are using.
14 Case 2b: Port-based VLAN (See Fig.2-5). 1. VLAN1 members could not access VLAN2, VLAN3 and VLAN4 members. 2. VLAN2 members could not access V L AN1 and VLAN3 members, but they could access VLA N 4 members. 3. VLAN3 members could not acce ss VLAN1, VLAN2 and VLAN4.
15 2-1-4. Configuring the Management Agent We of fer you three way s to startup the switch management funct ion. They are RS-232 console, CLI, and W eb. Users can use any one of them to monitor and configure the switch. Y ou can touch th em through the following procedures.
16 2-1-4-1. Serial RS-232 Port T o perform the configuration through RS-232 consol e port, the switch’s se rial port must be directly connected to a DCE device, for example, a PC, through RS-232 cable with DB-9 con nector . Next, r un a terminal emulator with the default setting of the switch’s serial port.
17 • Set IP Address, Subnet Mask and Default Gate way IP Address Please refer to Fig. 2-7 CLI Management for details ab out LevelOne’s setting. They are default setting of IP addre ss. Y ou can first either configure your PC IP addre ss or change IP address of the swit ch, next to change the IP address of default gateway and subnet mask.
18 2-1-4-2. Ethernet Port There are three ways to configure and monitor the switch th rough the switch’ s Ethernet port. They are CLI, W eb browser and SNMP manager . The user interface for the last one is NMS depende nt and does not cover here. W e just introduce the first two types of management interface.
19 Fig. 2-10 the Login Screen for Web 2-1-5. IP Address Assignment For IP ad dress configuration, there are three parameters ne eded to be filled in. They are IP address, Subnet Mask, Default Gateway and DNS. IP addre ss: The address of the network device in the network is used for internetworking communicati on.
20 With the classful addressi ng, it divides IP address int o three classes, class A, class B and class C. The rest of IP addres se s are for multicast and broadcast. The bit length of the network prefix is the sa me as that of the subnet mask an d is denoted as IP address/X, for example, 192.
21 Class D and E: Class D is a cla ss with first 4 MSB (Most significance bit) set to 1-1-1-0 and is used for IP Multicast. See also RF C 1 1 12. Class E is a class with first 4 MSB set to 1-1-1-1 and is used for IP broadcast.
22 In this diagram, you can see the subnet mask with 2 5-bit long, 255.255.255.128, cont ains 126 members in the su b-netted network. Another is that the length of network prefi x equals the number of the bit with 1 s in that subnet mask. With this, you can easily count the number of IP addresses matched.
23 For different network applications, the subnet mask may look like 255.255.255.240. This means it is a small network accommodating a maximum of 15 nodes in the network.
24 2-2.
