Store-and-Forward switching: Here the LAN switch copies the entire frame into its buffers and computes the CRC. Use the “no” form of the switchport command to enable layer3 functionality. The first command enters interface configuration mode for the switch interface /, and the second command enables layer 2 functionality on the port. The enable a switch port for layer 2 functionality use the following commands: The command allows you to create a new domain (in case the first switch is being configured) or to join an existing domain (one or more switches have already been assigned a domain).ġ2.

The password is required if the domain need to be secured by a password. For subsequent switches, you only need to join the existing domain. You need to create a domain while configuring the first switch in a switch network. The command syntax for assigning a management domain for a switch is:įor example, if the domain name is newyork, the command is: Switch# vtp domain newyork The following are the typical steps in preparing a switch for telnet access:ġ1. To telnet to a switch, the following are required:Īssignment of ip address and subnetmask to the management vlan,Īssignment of default gateway IP address. Switchport port-security mac-address : You can use this option to manually define the MAC address allowed for this port rather than letting the port dynamically determine the MAC address.ġ0. You can also manually associate a specific MAC address to a given port by issuing the command: Switch(config-if)#switchport port-securityīy default, the port is locked to the first MAC address that it learns via the port.
Typical configuration commands for enabling port security are given below: Port security enables securing switch ports as required. The current version of IOS running in a switchĥ. The “show version” command on a Catalyst switch displays

Network management software like CiscoWorks,Ĥ. Cisco switches can be managed out-of-band or In-band. However, it builds the MAC table learning from the frames that arrive at its ports by adding the MAC address and the corresponding port that it had arrived to the MAC table.ģ. The MAC address table of a switch would be empty to begin with. A frame’s IP address doesn’t change when being forwarded through a switch.Ģ. Switches forward packets based on the physical address (such as MAC address) whereas, routers forward packets based on logical address (such as IP address).
