Spanning Tree
1.1 Overview
STP
STP (Spanning Tree Protocol) is a layer 2 Protocol that prevents loops in the network. As is
shown in Figure 1-1, STP helps to:
Block specified ports of the switches to build a loop-free topology.
Detect topology changes and automatically generate a loop-free topology.
Figure 1-1 STP Function
STP
RSTP
RSTP (Rapid Spanning Tree Protocol) provides the same features as STP. But RSTP also
provides much faster spanning tree convergence.
MSTP
MSTP (Multiple Spanning Tree Protocol) also provides the fast spanning tree convergence
as RSTP. In addition, MSTP enables VLANs to be mapped to different spanning trees ( MST
instances), and traffic in different VLANs will be transmitted along their respective paths,
implementing load balancing among VLANs.
1.2 Basic Concepts
1.2.1 STP/RSTP Concepts
Based on the networking topology, this section will introduce some basic concepts in STP/
RSTP.

- Overview
- Unit id
- Stack master election and re election
- The stack master contains the saved and running configuration files for the stack the configuration files include the global settings for the stack and the interface settings for each switches in the stack
- The provisioned configuration retains in the stack when the stack member leaves the stack one application of this feature is shown below if a stack member fails and you replace it with an identical model and pre configure the new switch s unit id the same as the fail one s the stack applies the provisioned configuration to the new member that is the new one and the old one have exactly the same global settings and interface settings
- The provisioned configuration can be manually created or is automatically created when a switch is added to the stack and no provisioned configuration exists
- The following table lists the events that occur when the stack compares the provisioned configuration with the provisioned switch what configuration will be applied to the new member and what will happen to the provisioned configuration file
- Provisioned configuration
- For back up purposes all the stack members receive synchronized copies of the configuration files from the stack master if the stack master becomes unavailable all the other switches in the stack have the latest stack configuration files and the switch with the highest priority value becomes the new stack master
- Configuration synchronization
- You can use the provision feature to pre configure a new switch before it joins the stack you can configure in advance the stack unit id the switch type and the interfaces associated with the switch which is not currently part of the stack this configuration that you create on the stack is called the provisioned configuration the switch that is added to the stack and that receives this configuration is called the provisioned switch

- Configuring dhcp relay
- Chapters
- Overview
- Dhcp relay solves this problem as the following figure shows the dhcp relay device acts as a relay agent and forwards dhcp packets between dhcp clients and dhcp servers on different subnets so that dhcp clients on different subnets can share one dhcp server
- Dhcp relay is used to process and forward dhcp packets between different subnets
- Since the client requests a dynamic ip address via broadcast the basic network model of dhcp requires that the client and the server should be on the same lan therefore each lan should be equipped with a dhcp server thus increasing the costs of network construction

- Configuring voice vlan
- Chapters
- Overview
- Configuration guidelines
- Before configuring voice vlan you need to create a vlan for voice traffic for details about vlan configuration please refer to configuring 802 q vlan
- Because the voice vlan in automatic mode supports only tagged voice traffic you need to make sure traffic from the voice device is tagged to do so there are mainly two ways
- You can configure the voice device to forward traffic with a voice vlan tag
- Voice vlan configuration
- Vlan 1 is a default vlan and cannot be configured as the voice vlan
- To complete the voice vlan configuration follow these steps
- To apply the voice vlan configuration you may need to further configure pvid port vlan id and the link type of the port which is connected to voice devices we recommend that you choose the mode according to your needs and configure the port as the following table shows
- Optional configure oui addresses
- Only one vlan can be set as the voice vlan on the switch
- If your switch provides the lldp med feature you can also configure it to instruct the voice device to send tagged voice traffic for details about lldp med please refer to

- Tips the logged in guests can get administrative privileges by using the command enable admin and providing the enable password
- The accounts created by the radius tacacs server can only view the configurations and some network information without the enable password
- Some configuration principles on the server are as follows
- On the server
- On tacacs server the enable password is set with the login account and each account has its own enable password
- On radius server the user name should be set as enable and the enable password is customizable all the users trying to get administrative privileges share this enable password
- For login authentication configuration more than one login account can be created on the server besides both the user name and password can be customized
- For enable password configuration
