Mapping an MST Instance to a VLAN
The instance vlan command, in Protocol MSTP Configuration mode, maps VLANs to an
MST instance. The no form of this command unmaps all the VLANs that were mapped to an
MST instance.
BiNOS supports up to 16 instances. Each spanning tree instance is identified by an instance
ID that ranges from 0 to 15. Instance 0 is mandatory and is always present. Instances 1
through 15 are optional.
When you map VLANs to an MST instance, the specified VLANs are added to or removed
from the existing list.
To specify a VLAN range, use a hyphen. For example, instance 1 vlan 1-63 maps VLANs 1
through 63 to MST instance 1.
To specify a list of VLANs, use a comma. The list must be entered in increasing order of ID
numbers. For example, instance 1 vlan 10, 20, 30 maps VLANs 10, 20, and 30 to MST
instance 1.
Command Syntax
device-name(cfg protocol mstp)#instance <instance-id> vlan VLAN-LIST
device-name(cfg protocol mstp)#no instance <instance-id>
NOTES 1. The VLAN blocking is implemented by removing the port internally from that VLAN. This
can cause InErrors counter of such port to increase in cases of flooding or when port
changes its role due to topology changes.
2. When port is member of tagged VLAN – the secure block port feature should be used.
Argument Description
instance-id The MST instance ID. The range is 1 to 15.
VLAN-LIST The list of VLANs to add to the instance mapping. The range of values is <1-4094>.

Setting the Bridge Priority

The mstp priority command, in Protocol Configuration mode, sets the bridge priority for an
MST instance. The no form of this command resets the switch priority for the MST instance.
Command Syntax
device-name(cfg protocol)#mstp <instance-id> priority <priority>
device-name(cfg protocol)#no mstp <instance-id> priority
