Bandwidth: the amount of data that can be carried on a link in a given time period Vlan1 unassigned YES unset administratively down down Routers In the first step of creating the EUI-64 address, the value FFFE is inserted into the middle of the MAC address, thereby expanding the MAC address from 48 bits, which is 12 hexadecimal characters, to 64 bits, which is 16 hexadecimal characters. The conversion of the 48-bit MAC address into the 64-bit EUI address is illustrated in Figure 3.18 below: ---- ------- ------ ------------------------------ Variable Length Subnet Masking Using VLSM IPv6 prefix advertisement uses ICMPv6 Router Advertisement messages, which are sent to the all-hosts-on-the-local-link IPv6 Multicast address FF02::1. By design, only routers are allowed to advertise prefixes on the local link. When stateless autoconfiguration is employed, it is imperative to remember that the prefix length used must be 64 bits (e.g., 2001:1a2b::/64). You can steal bits from the host portion to use for subnets, but there should never be a reason to and it would break the ability to use many of the features IPv6 was invented to utilize, including stateless autoconfiguration. Domain: a specific part of a network Access Links Exercise 1: Write out the binary equivalents for the addresses below, and then determine which bits match. I have written the first two octets for you to save time. VLANs are a fairly straightforward feature which rarely requires troubleshooting. A few of the problems that you will see are mostly configuration errors. We will cover Layer 2 troubleshooting in detail on Day Why is UDP used at all? TCP uses a lot of bandwidth on the network and there is a lot of traffic sent back and forth to set up the connection, even before the data is sent. This all takes up valuable time and network resources. UDP packets are a lot smaller than TCP packets and they are very useful if a really reliable connection is not that necessary. Protocols that use UDP include TFTP. 8.Convert 15 from hex to binary and decimal Therefore, your mask will be 255.255.255.128, and your subnets will go up in increments of 128. You can’t actually steal less than 1 bit for a Class C address; this will give you only two subnets: Switch1(config-if)#switchport trunk encapsulation isl Switch1(config-if)#switchport mode trunk FF02::2 FF02::1:FF00:1 FF02::1:FF00:1111 Administrative Mode: dynamic auto 2001:123:abc:8b::/56 172.16.100.0 Serial Line Switch#conf t In order to reflect the role of modern CCNA engineers, you are now expected to know a little more about how they do their job. However, configuration IP addressing (using binary and hexadecimal) Situations in which you can communicate with some IP addresses but not all of those that are available. This is usually the most difficult problem to troubleshoot because it has many possible causes. The show interface trunk output now looks like this: IPv6 Addressing Write out subnets 192.168.16.0/24 through to 192.168.31.0/24. Now write out the supernet address you would advertise out if you owned all these networks. Stateful DHCPv6 – M flag set to 1 tells the host to use DHCPv6 for all address and network information. Routers Switch1(config)#interface fa0/15 This would take a very long time because there are over 8000 subnets (2 to the power of 13 gives you 8192, and you can check this using the design section of the Subnetting Secrets cheat sheet). History of IPv6 Fit for Purpose? Switch1(config)#int fast 0/2 Switch1(config-if)#duplex ? Cisco all but removed wireless from the previous version of the CCNA exam after they created CCNA Wireless certification. However, there has been a shift in thinking for the current CCNA syllabus, with Cisco customers (who influence the syllabus) saying that they expect their CCNA-level engineers to understand wireless basics as part of their day-to-day role. The same goes for many of the new CCNA syllabus items, such as Layer 2 security,ccna 200-301: lab assessments test, firewalls, BGP, etc.
