Learning Forwarding
Hello Time (2 Seconds) Forward Delay(15 Seconds)
Timers
MaxAge (20 Seconds)
1 instace of STP Over the Native VLAN
Common Spanning Tree
CST Disables BPDUs on a port(Dangerous) BPDU Filtering
dot1Q based
Requires PortFast 1 instance of STP per VLAN Per-VLAN Spanning Tree
PVST
Simply detects loss of BPDUs
ISL Based W/O Loop Guard: Port Starts Forwarding
Protecting STP
Interoperabilitybetwen CST/PVST Per-VLAN Spanning Tree Plus
Loop Guard With Loop Guard: Port Becomes Loop-inconsistent
PVST+ Loss of BPDUs
Operates over both dot1Q and ISL
Types of STP:
Doesn't actually detect unidirecitonal links
Spanning Tree Protocol
Root Port
Unidirecitonal Link Detection UDLD
Designated Port
Works by sending keepalives Port Roles
Alternate Port Backup Port
Discarding Learning
Port States Portfast
Forwarding
BPDUs sent from all switches
