STP Port States:--
Blocking: The Port listens to the BPDU MassagePorts in the blocking state do not forward or receive any frame. The frames will be discarded on arriving at that port and this port will not learn any MAC address.
Listening: The port in the listening state can send and receive the BPDU frames. However, listening ports do not forward any incoming frames. They also do not learn any MAC address.
Learning: The port in the learning state already identifies its state in the STP domain.It will be learning the MAC address from the frames arriving at the port in order to populate the MAC address table.
Forwarding: The port in the forwarding state will forward all Ethernet traffic as per the switch operation. Also, the port will process all incoming frames and will actively learn MAC address from the arriving traffic
VTP MODES:--
The different types of VTP MODES are as shown
Server Mode:- VTP server mode is the default mode for all catalyst switches. Here, you can create, modify and delete VLANs for the entire VTP domain.
Client Mode:- Receives information from the VTP servers, It sends and receives updates, VLAN information is received from the VTP servers.
Transparent:- Switches do not participate in the VTP domain, switches can add and create VLANs, Switches do not advertise hence do not accept VLAN based on advertisements, but forwards VTP advertisements received by trunk ports.
Configuring and Verifying PVST:--
To configure S10 as the ROOT bridge for VLAN 2 & SW2 as the root bridge for VLAN 2 we can use either one of the two commands.
Questions:-
- What are the STP port states
- What are the VTP modes
- What is use the client VTP
