Whether it's on a Cisco router or a network device such as a Cisco switch, the standard ACL access control list is always unable to match both the traffic source address and the destination address, nor does it meet the requirements of the "granular" control of the current network world, such as: A service function that allows access to a server, However, pinging
After the FLASH space is insufficient, I specially query the hardware configuration of the 6509 core device. The default Flash of the 6509 standard configuration is 64 MB, and the standard IOS size is 32.1 MB, the IOS 12.2 (17a) SX version to be upgraded has a size of 40.6 MB. In this case, it seems that the space is insufficient. However, this problem is well solved. The original IOS in Flash is deleted and then uploaded. So enter the command: Router # delete sup-bootflash: s72033-pk9sv-mz.122-

Disable forwarding of a specific MAC address on a cisco SwitchIt is really annoying to see other illegal DHCP in the LAN. In addition to the dhcp snooping method, you can also directly disable the mac address! The MAC address of machine A is 00-01-02-03-04-05, which is connected to port F0/3 of Switch B, port F0/3 is in VLAN3. Currently, forwarding of A is blocked on port B. You can set the following accord
A Dell machine with a network card of M is connected to a Cisco switch. The error err-disabled occurs because of link-flap, that is, the network card is up and down too frequently in a short time. This error is not returned when a vswitch interface is changed. The cause is unknown.

Last year to do some of the MATLAB GUI program, and now to do related things, in retrospect, a lot of experience was not recorded, and now look back always feel uncomfortable, so from now on, we must write records.Let's start with a simple example.There are usually two ways to create a Matlab GUI interface:1. Directly add controls dynamically using. m files2. Use

Now we're starting to learn some interesting parts of GUI programming: applications that use dialogs as the primary interface. We'll cover this process in two separate classes. Theory: If you pay close attention to the previous program, you will find that you cannot press the TAB key to jump from one child window control to another, and if you want to move it, click it with a mouse. This is not friendly t
