1. Foreword The configuration register is a 16-bit virtual register that specifies the order in which to start the router, interrupt parameters, and set the console baud rate. The value of the register is usually expressed in hexadecimal. The configuration Command Config register allows you to change the value of the configuration register. 2. Start Order Configure the last 4 bits of the register, specifying the location of the boot file that the router must use when it starts: R>l 0x0000 d

the bound hostNote:The above command sets a port on the switch to bind a specific MAC address, so that only this host can use the network, if the NIC of the host is changed or another PC wants to use the network via this port, it will not be available unless the MAC address bound to the port is deleted or modified.Note:The preceding functions are applicable to Cisco 2950, 3550, 4500, and 6500 series switches.2. solution 2-Expanded access list based o

The introduction of vlan of a Huawei switch and three VMPS modes. In the explanation of vlan of a Huawei switch, there are three VMPS modes (but User Registration Tool, namely URT, only supports open mode ). How to configure dynamic vlan and VMPS of a CATALYST 4500 series switch? This article takes cisco ios 12.2 (31) SGA as an example. 1. Introduction to VMPS: VMPS is short for the Huawei vlanMembership Policy Server. as its name implies, it is a cen

It is difficult to query using common SQL statements, but using OLAP functions is very simple, as shown in the following SQL: Select Row_number () over () as serial number, Row_number () over (partition by dept order by salary) as department number, Name as name, Dept as department, Salary as salary, AVG (salary) over (partition by dept) as average salary, AVG (salary) over

scenario: P1 and P2 are located on each selfish network, each with its own NAT/FW, And the NAT/FW deployed by the ISP exists, this is a typical multi-layer NAT/FW situation. NA and NB indicate the NAT/FW of P1 and P2 respectively, and NC indicates the NAT/FW of ISP. In this case, for P1 and P2, there are three different IP addresses and ports. See table 1.Table 1 three different IP addresses/ports of P1 and P2IP address/port \ node P1, P2 P1 P2Private Network Address/port 10.0.0.1: 4321 10.1.1.

Take the Cisco 2950 vswitch as an example. log on to the vswitch and enter the management password to enter the configuration mode. Then, run the following command: Switch # config Terminal # Enter the Configuration Mode Switch (config) # interface fastethernet 0/1 # Enter the specific port configuration mode Switch (config-If) # switchport port-secruity # Configure port security mode Switch (config-If) switchport port-security Mac-address MAC (MAC address of the host) (Config-If) No switchport

security level, the security of Cisco routers is not higher than that of soft routers. Cisco uses Nat in the pix, which is basically the same as using NAT in its own IOS. Even so, Cisco routers are doing well in resisting DoS attacks, mainly because Cisco's IOS is not only an operating system, but also a routing/security software. This integration method is not only more concise than the software routing products that work on windows, but also enables fast updates whenever Cisco discovers a new

This paper mainly explains the process of estimating the current scene temperature in the white balance algorithm.The principle of color temperature calculation is not complicated, but to do well, or to do a good job of every step, this requires a lot of testing, and the algorithm is constantly improved.First, let's talk about the process briefly:1. Take a frame of image data and divide it into MXN blocks, assuming it is 25x25, and count the basic information of each block (the number of white p
