If needed, you can also configure some excluded addresses from the 192.168.1.0/24 range. Let’s say you want to exclude the router interface IP address (192.168.1.1) and the 192.168.1.250 to 192.168.1.255 address range, 2.DHCP Offer packet: The DHCP servers on the local network see the broadcasted Discover message sent by the client and send back a response (DHCP Offer packet) using UDP source port bootps 67 and destination port bootpc 68, also in the form of a broadcast address, because the client still doesn’t have an IP address so it cannot receive Unicast packets. You can see the server mode in the configuration and output above. Read today’s lesson notes (below) Complete today’s lab Be careful when applying network statements with OSPF,cisco 300-535, which also requires a wildcard mask. Changing VTP domain name from NULL to passhot One final point is that switch security can be configured on Packet Tracer, but many of the commands and show commands don’t work. Switchport: Enabled Administrative Mode: trunk Operational Mode: trunk The following output illustrates the configuration of inter-VLAN routing using a single physical interface (also referred to as “router-on-a-stick”). The two VLANs depicted in Figure 10.13 are shown in the following output, as is an additional VLAN used for Management; this VLAN will be configured as the native VLAN: Switch-1(config)#interface range FastEthernet0/1 – 2, 23 Switch-1(config-if-range)#switchport Switchport: Enabled Administrative Mode: trunk Operational Mode: trunk 4.2Troubleshoot client connectivity issues involving DNS Router1(dhcp-config)#lease 3 3 5 ‹ command won’t work on Packet Tracer Router1(dhcp-config)#exit 2.6.bLLDP Default gateway (router): 192.168.1.1 DNS server: 8.8.8.8 network 10.10.10.0 Figure 6.2 below illustrates the valid combinations that will result in the successful establishment of a trunk link between two neighboring switches – one using DTP and the other statically configured as a trunk port: Figure 10.7 shows the same packet leaving Router A for Router B. There is a route lookup and then the packet is switched out of interface E1. Type 800 indicates that the packet is IPv4. Here is an example of these commands in use: Once port security has been enabled, administrators can define the actions the switch will take in the event of a port security violation. Cisco IOS software allows administrators to specify four different actions to take when a violation occurs, as follows: The switch must be running CDP in order to identify the connected device as an IP phone. 4.Check the Layer 2 settings on the switch. Now, assume that Host 1 has been compromised by an attacker who wants to receive all traffic destined for Host 2. By using MAC address spoofing, the attacker crafts an Ethernet frame using the source address of Host 2. When the switch receives this frame, it notes the source MAC address and overwrites the CAM table entry for the MAC address of Host 2, and points it to port FastEthernet0/1 instead of FastEthernet0/2, where the real Host 2 is connected. This concept is illustrated below in Figure 9.
