A banner message will show when a user logs in to your router or switch. It won’t offer any actual security but it will display a warning message of your choice. In the configuration below, I chose the letter Y as my delimiting character, which tells the router that I’ve finished typing my message: R1#ping 2001:AAAA:BBBB:EEEE::1 Gateway Distance Last Update 10.0.0.2 115 00:06:53 Day 6 Tasks DTP is a Cisco proprietary point-to-protocol that negotiates a common trunking mode between two switches. DTP will be described in detail later. The following output illustrates how to configure a switch port to use IEEE 802.1Q encapsulation when establishing a trunk: 　　show interface switchport Here is an example output: Type escape sequence to abort.

Internet Protocol Routing Fundamentals BranchRouter(config)#ip route 192.168.1.0 255.255.255.0 172.16.5.3 115 VTP version 3 differs from VTP versions 1 and 2 in that it distributes a list of opaque databases over an administrative domain in situations where VTP version 1 and VTP version 2 interacted with the VLAN process directly. By offering a reliable and efficient transport mechanism for a database, usability can be expanded from just serving the VLAN environment. Access control lists often block DNS, so this is another possible cause of problems. You can debug DNS on the router with the debug domain command. Copyright (c) 1986-2005 by Cisco Systems, Inc.

Figure 6.1 below illustrates the DTP mode combinations that will result in a trunk either being established or not being established (in this case they are all established; see note after Figure 6.2) between two Cisco Catalyst switches: Fa0/2 on 802.1q trunking 1 command. Default port security configuration parameters can cause operational issues with other features, such as first hop redundancy protocols which we cover later (i.e., HSRP, VRRP, and GLBP) because only a single MAC address is allowed per port. This can be validated via the show port- After verifying that the relevant prefixes are indeed present in the routing table, you should carefully analyze their attributes and the path selection method for each of them. This might include: Router#conf t Management Addresses - not advertised Auto Negotiation - supported, enabled The commands above may not work if you are using Packet Tracer. Also, please do try these commands on a router because they are exam topics. Bear in mind that you should disable the ACL on the interface (so it’s no longer live) before you edit it in order to avoid strange or unpredictable behavior. I’ll show you how to edit live ACLs on IOS 12.4 and later shortly. Trunking Native Mode VLAN: 1 (default) router rip version 2 no auto Connect to the switch using a console connection. Connect a PC to each switch or connect the switch to the fast ethernet port on a router. If you can’t ping across a directly-connected link, then you need to fix that issue before checking for routing issues. Next, check your routing configuration. You need to ensure that there are no unwanted passive Version : Switchport: Enabled Version : Cisco Discovery Protocol (CDP) 3.4.d Single vs dual-homed [ICND2] The switching process allows the router to accept the packet via one interface and send it out of another. The router will also encapsulate the packet in the appropriate Data Link frame for the outgoing link.

Switch-1(config)#vlan 20 Configuring a switchport to support IP phones is not as complex as you may think once you understand the full capabilities of what an access port can do. For example, even though a port connected to a phone acts like an access port, the voice frames are tagged with an 802.1Q header so that the switch and the phone will understand what is voice traffic versus data traffic.

If the link that connected to 172.16.4.2 went down, that route also would no longer show up in the routing table. That being said, using a different example, as shown in Figure 11.7 below, if the downstream router, Router 3, that is hosting 192.168.2.0/24 stopped working, R1 would continue to forward traffic to the next hop using static routes, because static routes are not aware of whether there are issues further downstream.
