Nganjeher nje port speciifik brenda ciscos mund te ndalet per arsye te ndonje loop/ndonje sinjali te mundshem qe i vie brenda nje switchi dhe nepermjet atij sinjalit si detyre specifike e cisco MultiLayer switchit/routerit eshte ta ndal ate port specifik derisa shfrytezuesi te ndermerr ndonje hap per rregullimin e atij problemit dhe pastaj te aktivizoj portin specifik.
Nganjeher kete aktivizim duhet ta aktivizojme duke e kontrolluar se pari portin specifik a ka kaluar ne error-disabled-mode.
cat6knative#show interfaces gigabitethernet 4/1 status Port Name Status Vlan Duplex Speed Type Gi4/1 err-disabled 100 full 1000 1000BaseSX
Nese portin specifik brenda nje switchi e kemi ne kete status ateher menyra manuale e aktivizimit te portit do te ishte duke shkuar ne te dy switchat qe nderlidhen ndermjet veti dhe ne portat specifik te tyre dhe duke realizuar nje shutdown dhe no shutdown.
Me kete fillohet ri-negocimi i portave brenda te dy switchave dhe lidhja point-to-point funksionon prap si duhet.
psh. Switch1

Nganjeher ky hap na shpien deri te dergimi i nje ekipe te caktuar deri ne bazen tone te paisjeve prandaj preferohet ne qfardo rasti te aktivizohet error-disable-recovery
Hyjme ne modin e konfigurimit ne switchi1:

*Shtypim komanden per tu ri-gjeneruar nga te gjitha problemet e ndryshme qe hasemi brenda switchit
errdisable recovery cause all
default error recovery eshte 300s mirepo kete mund ta nderrojme duke shtypur komanden e meposhtme (30-86400s)
errdisable recovery interval 180
