Command Attributes
Basic Configuration of Global Settings
• Rapid Spanning Tree
RSTP supports connections to either STP or RSTP nodes by monitoring the
lly adjusting the type of protocol incoming protocol messages and dynamica
messages the RSTP node transmits, as described below:
ode – If the switch receive - STP M
port’s migration delay timer expires, the switch assumes it i
802.1D bridge and starts using only 802.1D BPDUs.
- RSTP Mode – If RSTP is using 802.1D BPDUs on a port and receives an
RSTP BPDU after the migration delay expires, RSTP restarts the migration
