Windowing ROM: C2960 Boot Loader (C2960-HBOOT-M) Version 12.2(25r)FX, RELEASE SOFTWARE (fc4) Basic Switching Troubleshooting Switch1(config-if)#switchport access vlan 5 Don’t worry, though; this is a process, not a one-off event, so follow my notes and then feel assured that we will be coming back to review these concepts many times. This topology was created with the first Ethernet networks, where all devices had to be connected to a thick cable referred to as the backbone. If the backbone cable fails, then the network goes down. If a cable linking the device to the backbone cable fails, then only that device will lose connection. Following the site prefix, the next 64 bits are used for interface or host addressing. The interface or host ID portion of an IPv6 address represents the network device or host on the IPv6 subnet. The different ways in which the interface or host address is determined will be described in detail later in this module. Figure 3.3 below illustrates how IPv6 prefixes are assigned: 172.16.64.0 Router#sh ip interface brief The OSI Model Determining how many APs are required in a specific location is done via a Hex to binary is carried out using the same process. For example, 7C can be split into 7, which is 0111 in binary, and C (12 in decimal), which is 1100 in binary. The answer, then, is 01111100. Within a site, administrators can then subnet the provider-assigned 48-bit prefix into 64-bit site prefixes by using bits 49 through 64 for subnetting, allowing for 65,535 different subnets for use within their network. The host portion of an IPv6 address represents the network device or host on the IPv6 subnet. This is represented by the low-order 64 bits of the IPv6 address. Subnetting allows you to steal bits of an IP address which were traditionally used for hosts on the network. You can now carve smaller networks from your larger network space, and these smaller networks are referred to as subnetworks, or subnets for short. R1#show ipv6 interface brief R1#show ipv6 interface f0/0 R1#show ip interface brief Hardware is CPU Interface, address is 0010.1127.2388 (bia 0010.1127.2388) Internet address is 192.168.1.3/24 Ethernet Link ICMP is used to report errors and other information to the source hosts regarding the delivery of IP packets to the intended destination. ICMPv6, which is defined in RFC 2463 as protocol number 58, supports messages for ICMPv4 and includes additional messages for ICMPv6. ICMPv6 is used in the Next Header field of the basic IPv6 packet header. Unlike in IPv4, IPv6 views ICMPv6 as an upper-layer protocol, such as TCP, for example,ccna routing and switching 200 301 pdf, which means that ICMPv6 is placed after all possible extension headers in the IPv6 packet. The fields that are contained within the ICMPv6 packet are illustrated in Figure 3.
