BranchRouter(config)#ip route 192.168.1.0 255.255.255.0 172.16.5.3 Along with subnetting and VLSM, access control lists (ACLs) are one of the bugbear subjects for new Cisco students. Among the problems are learning the IOS configuration commands, understanding ACL rules (including the implicit “deny all” rule), and learning the port numbers and protocol types. switchport port-security mac-address sticky 0004.c16f.8741 switchport port-security mac-address sticky 000c.cea7.f3a0 switchport port-security mac-address sticky 0013.1986.0a20 switchport port-security mac-address sticky 001d.09d4.0238 switchport port-security mac-address sticky 0030.803f.ea81 !!!!!

However, unlike static secure MAC addresses, dynamic secure MAC address entries are removed from the switch when the switch is reloaded or powered down. These addresses must then be relearned by the switch when it boots up again. The default route source administrative distance is displayed in the output of the show ip protocols command. This is illustrated in the following output: SwitchA#conf t I’ve used Packet Tracer for this lab but you can use your own home lab if you have access to all the available equipment. Set the displayed IP address on each PC and put the default gateway to 10.10.10.254 for the top PC and 10.20.20.254 for the bottom PC.

Configuring Access Control Lists Loopback0 DNS uses UDP port 53 when a host or a router wants to resolve a domain name to an IP address (or vice versa). TCP port 53 is used between two DNS servers when they want to sync or share their databases (zone transfers) or when the response size exceeds 512 bytes. 4.1Describe DNS lookup operation Sticky MAC Addresses 0 Configuring Sticky Secure MAC Addresses Exec – shown to the user after the login prompt (used when you want to hide information from unauthorized users) summary-address Summary-address redistribution information timers OSPF timers information Take today’s exam The following output illustrates how to enable port security on an interface and to configure a static secure MAC address of 001f:3c59:d63b in VLAN 5 on a switch trunk port: In production networks with Cisco Catalyst 3750 switches, it is always a good idea to determine what the switch will be used for, and then select the appropriate Switch Database Management (SDM) template via the sdm prefer {access | default | dual-ipv4-and-ipv6 {default | routing | vlan} | routing In Figure 15.5 above, the incoming packet has a source and destination address, but your standard ACL will only look at the source address.

Two other commands are show cdp, which displays protocol information for the device, and show cdp entry , which shows information about a specific device by inputting the name. I recommend that you spend some time checking CDP outputs during the labs you will configure in this guide. 3.Put two fast Ethernet interfaces into VLAN2 for the hosts and add IP 1.DHCP Discover packet: When a device boots up and it is configured to obtain an address via DHCP, it sends a broadcast sourced from UDP port 68 (bootpc) out to UDP port 67 (bootps). The packet will reach every device on the network,300-420 ensld dump, including any possible DHCP servers located there. A common mistake when performing such a troubleshooting process is investigating the issue in a single direction (for example, source to destination). Instead, you should perform the troubleshooting in both directions because you might come across situations in which packets are blocked in a single direction and you have no return traffic from the destination to the source. The routing tables on devices along the path between two points should correctly point in both directions in order to ensure an optimal traffic flow.
