Using the firewall and the memory pool MIB (using the Firewall and Memory pool MIBs)
The Cisco firewall and memory Pool MIB allow you to poll for failover and system state. This section includes the following:
o ipaddrtable notes (ipaddrtable notes)
o Browse for failover status (viewing Failover status)
o Verify memory usage (verifying Memory Usage)
o Browse Connection number (viewing the Connection count)
o Browse System cache usage (viewing systems

I. Overview:
Cisco routers have a lot of IKEV2 for the IKEV2, so you can configure them with little configuration.
Two. Basic ideas:
A. Configure flex VPN on both sides in a svti manner
B. No dynamic routing, configuration of static routes, if one side with Dvti, you need to configure static routes on both sides
Three. Test topology:
Four. Flex VPN configuration:

Problem with Cisco router password recovery
The Cisco 2500 router has several passwords, including the Enable secret,enable password,telnet password, and so on. The Enable secret is the most important, the password must be forgotten after the use of extraordinary means to recover. The following is a brief description of the
The previous one to everyone talked about the basic operation of Cisco switches, before the Dragon Boat Festival holiday, the Cisco switch to share a simple configuration and wish you a happy Dragon Boat festival! Ok, to configure the switch, you must first enter the switch's global configuration mode, successfully connecting to the switch and landing successfully into privileged mode

Global debugging
When configuring a Cisco router, the bounds of global and interface commands are obvious. In this case, we use "global" to identify those commands that cannot be used for interface debugging or for specific transport media types and protocol debugging. For example, in the 2500 series router, you can use the Debug command to analyze the Cisco Discovery Protocol (

He is a proprietary technology of the Cisco platform and is the private protocol of Cisco.In layman's terms, a local area network has two routing devices connected to the extranet, one as a host and a backup. Normally the primary (active) router works. When the primary router fails, the backup (standby) router

This article mainly introduces how to quickly configure the Cisco Router Network Assistant and provides specific operation steps. I believe this article will benefit you a lot after reading it.
Cisco provides Cisco Network Assistant CNA, a free tool for small and medium-sized enterprise SMBs, to help you configure Cisco
Some time ago, my colleague asked me a question about the DHCP configuration of the Cisco router. At that time, I did not give a positive answer, because this was my first time. In the following days, I have consulted relevant materials and are satisfied with the following answers. Share it with you now! In addition, most people do not know about the computer and do not operate these operations. Therefore, the customer asked us to allow any computer t
In the network industry, Cisco System Inc. is unknown. With its IOS (Internet Operating System), Cisco is an absolute leader in the multi-protocol router market. Currently, nearly 80% of routers on the Internet come from Cisco. In fact, Cisco also has a full range of network devices, including hubs, switches, access se
There are many users of Cisco routers. Here we mainly introduce how to keep Cisco routers away from DoS attacks. DoS Dictionary Attacks against routers allow attackers to gain access to Cisco routers or prevent users from using the routers. In this article, you can find out how to use the enhanced login function of the Cisco
With the development of China's routing industry, its market demand is also increasing. As a leader in the routing industry, Cisco routers have a very high market share. Telnet to the Cisco router for remote management is the choice of many network management, but the data transmitted through Telnet is in plain text, so this login method has a great security risk.
