A cloning port is a specialized endpoint on a switch that allows network administrators to replicate or copy network traffic from one port to another. This is often used for troubleshooting, network monitoring, or security analysis purposes. By using a cloning port, administrators can monitor and analyze data without disrupting the flow of traffic on the network.
A switch. Each port has a separate path to each of the other ports on the switch. On a hub, all the ports are tied together into 1 single port. Think of a switch as an 4 lane freeway with 8 entrances and exits; a hub is a one lane highway with the same 8 entrances and exits. It can pass data from only one port to another port- switch can connect 4 ports to the other 4 ports (or 8 to 8 or 16 to 16, you get the idea) A switch is quite a bit more complicated AND is generally more expensive: between 20% and 300% more than a hub with the same number of ports BUT it's very useful on a busy network (business especially.)
Port Mirroring
The Switch by paying attention to the traffic that comes across it, it can "learn" where particular addresses are. For example, if it sees traffic from machine A coming in on port 2, it now knows that machine A is connected to that port and that traffic tomachine A needs to only be sent to that port and not any of the others. The net result of using a switch over a hub is that most of the network traffic only goes where it needs to rather than to every port. On busy networks this can make the network significantly faster.
An Uplink Port is a port on a connectivity device, such as a hub or switch, used to connect it to another connectivity device.
Port security is used on a switch and the number of secure MAC addresses for a port is reached, the violation mode that will typically cause an SNMP trap to be sent and traffic to be dropped is the "Shutdown" or "Protect" violation mode.
the switchport access vlan 99 command is used to designate a specific VLAN for a switch port, allowing you to control how traffic on that port is treated and segregated from traffic on other ports and VLANs in the network. This is a fundamental configuration step in building and managing VLANs within a network infrastructure.
Switch because it is at least a little intelligent and can send data packets to the correct port.-----------A switch also regenerates the network signal, where a hub does not.
If you connecting a hub to another device then the cable must be placed in the uplink port, or a port that can switch between a client port and an uplink port.
This feature is named "port mirror" or SPAN. You need to get a manageable switch to have this feature. You also need to setup a passive monitoring program(ie: WFilter) to monitor the traffic.
The source MAC address within a frame is used by the switch to associate a port with that MAC address. Frames are directed by the switch from one port to another based on the destination MAC address within the frame.
LDAP uses port 389 for encrypted traffic.
