An instance of VLAN configuration for Cisco L3 switches and L2 SwitchesCisco VLAN implementation is usually port-centric. The port connected to the node determines the VLAN in which it resides. There are two ways to allocate a port to a VLAN: Static and Dynamic. The process of creating a static VLAN is to forcibly allocate the port to a VLAN. That is, we first create a VLAN on The VTP (VLAN Trunking Protocol) server, and then assign each port to the corresponding VLAN. This is the most common me

In the middle of a Cisco switching network, how do I find out which port of the switch is connected to the IP address of a machine? The most convenient and quick way is to use the User tracking function of the CiscoWorks 2000 LMS network management software. The graphical interface is clear at a glance.

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 an
