Common HWIC modules include HWIC.2T, HWIC.2FE, HWIC-1ADSL, HWIG16A, HWIC-4ESW, HWIC-4ESG, VWIC3-1MFT-T1/E1 and HWIC-4G-LTE-G. The reader should select the appropriate module according to the actual network requirements, and it needs to be purchased separately. According to the above router interface naming principle, the name of the A interface in Figure 1-3 is SO/O/LB interface is FaO/3/O,where the 1st digit indicates the slot number, the 2nd digit indicates the module number, and the 3rd digit indicates the port number of the module.3 Service module slot number is 1, the specific interface name depends on what module is selected, for example, if the SM-ES3-16-P switch module is purchased, the name of the first interface is Gl/0o1.1.2 Switch Interface NamingThe WS-C3560V2-24PS-S switch in the experimental topology of this book is used as an example to illustrate switch interface naming. This switch is an energy-efficient Layer 3 switch in a fixed-port configuration that contains 24 100-bit Ethernet interfaces and two Small Form-factor Pluggables (SFP) Gigabit Ethernet expansion interfaces (requires corresponding SFP modules). The 24 100-bit Ethernet interfaces support Power over Ethernet (PoE) capability. The switch interfaces are named as shown in Figure 1-4, where interface A is named FaO/1, interface B is named FaO/14, and interface C is named G0/1.Figure 1-4 Switch Interface Naming1.1.3 Terminal Access Server ConnectionDuring experiments, comprehensive and complex experiments will use multiple routers or switches, and if you connect to the console (Console) port of a network device through the computer's serial communications interface (COM port), since one COM port of the computer can only.6.Cisco Networking Lab CCNA Lab Guide (2nd Edition) connects to one network device, it requires multiple computers or frequently unplugging the Console cable that connects the network device, which is very inconvenient and may also burn out the Console port of the network device, causing damage to the device. Terminal Access Server can solve thisThe Terminal Access Server solves this problem. The terminal access server and the network device are connected as shown in Figure 1.5. The terminal access server is usually a router equipped with HWIC-8A module or HWIC-16A module, from which multiple cables are connected to the Console port of each controlled device. When using, the user first accesses to the terminal access server through the computer COM port or Telnet, and then accesses to each router, switch and other controlled devices from the terminal access server, so that the access to multiple devices can be controlled on one computer at the same time without frequently plugging and unplugging the Console cable.Figure 1.6 Router IOS Download Page
