Cisco me 3400 Guia Do Programa

This example shows how to configure an interface as the primary edge port for segment 1, to send STCNs 
to segments 2 through 5, and to configure the alternate port as the port with port ID 0009001818D68700 
to block all VLANs after a preemption delay of 60 seconds after a segment port failure and recovery. 
The interface is configured to remain up for 6000 milliseconds without receiving a hello from a neighbor. 

Switch# configure terminal

Switch (conf)# interface gigabitethernet0/1

Switch (conf-if)# rep segment 1 edge primary 

Switch (conf-if)# rep stcn segment 2-5 

Switch (conf-if)# rep block port 0009001818D68700 vlan all

Switch (conf-if)# rep preempt delay 60 

Switch (conf-if)# rep lsl-age-timer 6000 

Switch (conf-if)# end

This example shows how to configure the same configuration when the interface has no external REP 
neighbor:

Switch# configure terminal

Switch (conf)# interface gigabitethernet0/1

Switch (conf-if)# rep segment 1 edge no-neighbor primary 

Switch (conf-if)# rep stcn segment 2-5 

Switch (conf-if)# rep block port 0009001818D68700 vlan all

Switch (conf-if)# rep preempt delay 60 

Switch (conf-if)# rep lsl-age-timer 6000 

This example shows how to configure the VLAN blocking configuration shown in 

alternate port is the neighbor with neighbor offset number 4. After manual preemption, VLANs 100 to 
200 are blocked at this port, and all other VLANs are blocked at the primary edge port E1 (Gigabit 
Ethernet port 0/1). 

Switch# configure terminal

Switch (conf)# interface gigabitethernet0/1

Switch (conf-if)# rep segment 1 edge primary 

Switch (conf-if)# rep block port 4 vlan 100-200

Switch (conf-if)# end
