- A vlan virtual local area network allows a physical network to be partitioned into multiple logical networks devices on a logical network belong to one group a device can belong to more than one group with vlan a device cannot directly talk to or hear from devices that are not in the same group s the traffic must first go through a router 84
- Chapter 8 basic setting 84
- General setup continued 84
- In mtu multi tenant unit applications vlan is vital in providing isolation and security among the subscribers when properly configured vlan prevents one subscriber from accessing the network resources of another on the same lan thus a user will not see the printers and hard disks of another user in the same building 84

- Protocol based vlans allow you to group traffic into logical vlans based on the protocol you specify when an upstream frame is received on a port configured for a protocol based vlan the switch checks if a tag is added already and its protocol the untagged packets of the same protocol are then placed in the same protocol based vlan one advantage of using protocol based vlans is that priority can be assigned to traffic of the same protocol 107

- Spanning tree protocol 125
- Stp rstp overview 125
- Stp terminology 125
- After a bridge determines the lowest cost spanning tree with stp it enables the root port and the ports that are the designated ports for connected lans and disables all other ports that participate in stp network packets are therefore only forwarded between enabled ports eliminating any possible network loops 126
- Allowed range 126
- Chapter 13 spanning tree protocol 126
- For each lan segment a designated bridge is selected this bridge has the lowest cost to the root among the bridges connected to the lan 126
- How stp works 126
- Link speed 126
- Mes 3728 user s guide 126
- On each bridge the root port is the port through which this bridge communicates with the root it is the port on this switch with the lowest path cost to the root the root path cost if there is no root port then this switch has been accepted as the root bridge of the spanning tree network 126
- Once a stable network topology has been established all bridges listen for hello bpdus bridge protocol data units transmitted from the root bridge if a bridge does not get a hello bpdu after a predefined interval max age the bridge assumes that the link to the root bridge is down this bridge then initiates negotiations with other bridges to reconfigure the network to re establish a valid network topology 126
- Path cost is the cost of transmitting a frame onto a lan through that port the recommended cost is assigned according to the speed of the link to which a port is attached the slower the media the higher the cost 126
- Recommended range 126
- Recommended value 126
- Stp aware switches exchange bridge protocol data units bpdus periodically when the bridged lan topology changes a new spanning tree is constructed 126
