spanning-tree rstp
Sets the priority value for RSTP.
Syntax
spanning-tree rspt priority priority value
Parameters priority priority value — Enter a bridge-priority value in increments of 4096, from 0 to 61440.
Valid priority values are: 0, 4096, 8192, 12288, 16384, 20480, 24576, 28672, 32768, 36864, 40960,
45056, 49152, 53248, 57344, and 61440. All other values are rejected.
Default Not configured
Command Mode CONFIGURATION
Usage
Information
RSTP determines the root bridge but you can assign one bridge a lower priority to increase the probability
of it being the root bridge. A lower priority value increases the probability of the bridge becoming a
root bridge.
Example
OS10(config)# spanning-tree rstp priority 200

Virtual LANs
VLANs segment a single flat L2 broadcast domain into multiple logical L2 networks. Each VLAN is uniquely identified by a
VLAN ID or tag consisting of 12 bits in the Ethernet frame. VLAN IDs range from 1 to 4093 and provide a total of 4093 logical
networks.
You can assign ports on a single physical device to one or more VLANs creating multiple logical instances on a single physical
device. The virtual logical switches spanning across different physical devices emulate multiple logically segmented L2 networks
on a single physical network.
Each VLAN has its own broadcast domain. The unicast, multicast, and broadcast network traffic from ports that belong to a
VLAN forwards or floods to ports in the same VLAN only. Traffic between VLANs routes from one VLAN to another. You can
also assign each VLAN an IP address to group all the ports within a single IP subnet.
Segment a L2 network using VLANs to:
● Minimize broadcast and multicast traffic in the L2 network
