no sh When these two commands are hit, the network segment above the core switch can access the external network in the theory. Why is it theoretical? For example, now there is nothing configured on the core switch. Only a network segment is divided. In this case, the public network above the main river. The above is my feeling of when I exam CISCO CCIE LAB and CISCO CCIE written exam. Hope you guys for your own dream to fight! Fighting! 4507B#license install usb0:/FXS1941Q21T_201605030017404860.lic no sh Question 3: Only one host can access each other and cannot access the public network. Don't say it again! Copy it to FLASH and then upgrade it is like this. From the above, you can see that there is a license for the basic version as well as a license for security and data versions. failover lan unit primary Sup7_E#sh license summary Sup7_E#sh license all Activate IP BASE version. When you activate,training ccna, under normal circumstances. There will be no problems but you may also encounter the following problems. That's the case of licensing errors. For Cisco, voice and security licenses often go wrong. However,the routing and switching are very few possibilities for error. But this time, there are 6 licenses and four of them have been activated. slot 0: ASA5510 hw/sw rev (.0/9.1() status (Up Sys) Switch Number: 1 Role: Virtual Switch Standby username CISCO privilege 15 password 0 cisco Conclusion: If the engine has a USB interface, it is best to use the USB interface to upgrade because of it is mainly fast.

After /no ip routing, write default-gateway to point to ISG1000. I believe that everyone is familiar with the configuration of these interfaces. The main configuration is the address of the WAN port that telecom gives to you, as well as the address of the intranet. Of course, NAT is generally required so NAT will be configured. INSIDE and OUTSIDE interface. Qtherwise, there is no way to do NAT. The internal network cannot be on the public network. Note that this is 0.0.0.0, which is mainly safer. 4507B#license install usb0:/FXS1941Q21T_201605030017404860.lic 4507B#sh run | in boot ip access-group 100 in Question 1: The customer now needs to be able to access each other between the network segments but can be connected to the public network. 1、Telephone method: boot system bootflash:/cat4500e-universalk9.SPA.03.08.01.E.152-4.El.bin int Ethernet0/1 no sh description lan As you can see, the activation is wrong here.

Now upgrade the standby engine. There are two ways to upgrade the standby engine. The first one is to take out the first upgraded engine and upgrade it directly. The second, the another possibility is to passively upgrade the second engine. Let's look at a command first: As shown Don't say it again! Copy it to FLASH and then upgrade it is like this. From the above, you can see that there is a license for the basic version as well as a license for security and data versions. The above is my feeling of when I exam CISCO CCIE LAB and CISCO CCIE written exam. Hope you guys for your own dream to fight! Fighting! Cisco Engineering will call you, then I will email the Cisco TAC to explain the reason. Later, Cisco TAC helped me register a .LIC file so I can be sure that it is Cisco's own problem. When doing a project, I often encounter such a small project. That is the customer only buys a Cisco router and a core switch. Now you need to configure the router and switch for the client to access the Internet. In fact, this small project looks very simple but it is very important and often encounters unsuccessful configuration or fails to meet customer requirements. Here is a detailed analysis of such a small project because through this such small projects can be derived from many different configurations and requirements, such as dual exports, etc. First look at the configuration of the router.
