, not the Native VLAN. Generally in the trunk interface is a tagged packet, then if there is no tagged data, this is used to the native VLAN, these do not label the data hit the native VLAN tag into the switch, Cisco Management VLAN and native VLAN default is VLAN 1. For a trunk port to receive a data frame without VLAN tags, 802.1Q will be native VLAN tag forward to native vlan[default to VLAN1 can be modified, if the modification to ensure that all

dynamically learns the MAC address, but this configuration will only be saved in the MAC address table and will not be saved in the running configuration file. After the switch is restarted, the MAC addresses in these MAC address tables are automatically cleared.Viscous and reliable MAC address: In this type, you can manually configure the binding between the MAC address and the port, or enable the switch to automatically learn to bind, this configuration is saved in the MAC address and in the

that the admin domain is able to overwrite all branch switches. The Cisco switch is capable of supporting any media as a trunk, and it can use its own ISL tags for relaying. ISL (Inter-Switch link) is a protocol between switches, between switches and routers, and between switches and servers to transfer multiple VLAN information and VLAN data streams, configured with ISL encapsulation via ports directly connected to the switch, The VLAN allocation a

VLANs.View VLANsEnter the command in privileged mode show VLAN brief can view the current VLAN status.You can see that all interfaces are under the default VLAN1. Creating VLANsWhen configuring a normal-range VLAN, the configuration details are stored in the switch flash memory named Vlan.dat file, the flash memory is permanent, and you do not need to use the copy running-config startup-config command. However, because other details are often configured on the

trunk protocol, which is an ISL, is also a encapsulation of VLANs, except that this is the Cisco Cisco Private Protocol. Other manufacturers are not available.
