7 Switch Configuration
• In the case of Kendin switches, there are restrictions when configuring the VLANs. Please see manual Teldat
Dm751-I VLAN
Use the following commands to configure Spanning Tree in a switch:
• port <port-id> stp enable instance <id> to enable Spanning Tree in a port and to associate it to a certain Span-
ning Tree instance.
• port <port-id> stp <parameters> to configure the different Spanning Tree protocol parameters associated to a
given port.
• stp <instance> <parameters> to configure the different Spanning Tree protocol parameters associated to a cer-
tain instance.
Per Vlan Spanning Tree (PVST) can also be used for the selected ports.
This means that each VLAN on a network can build its own Spanning Tree. All switch ports used in this instance
must be a member of the requested VLAN.
• stp <instance> vlan <vlan-id> to enable Spanning Tree using PVST.
• Feature vlan vlan <vlan-id> ethernet0/0 port x to enable vlan on switch port x.

7.4 Quality of Service

This feature is available in some switches and allows:
(1) To configure a limit on the output rate in a given switch port.
(2) To assign the default COS values to traffic from a port and execute re-tagging for some, or all, COS values.
(3) To configure different priorities, depending on the COS or DSCP values, and assign them to different output
queues (up to a total of four) in each port.
(4) To alter the output queue discipline, either globally or per port.
(5) To configure which input packet parameter in a port (COS or DSCP) is used for priority.
