Solucion a falla de software en rru de sitios u850 caso de se queda en boot y no arranca sw. dichos rrus, al revisarlo x el lado de u850 marcan el sector sin coneccion pero al dar el comando ps port_* nos da los puertos 0,1 y 2, se toma el puerto dañado en el caso este es el puerto 0 o sector 1, y del lado del lte se revisa y es iot 211 compartido con 21 de l850, la característica principal es que detecta sin coneccion al sector pero si hay conectividad con el rru y al momento de tirar comando sfp –a salen sin valores(la imagen de abajo es del lado de lte aplica igual para u850 por ser el mismo rru). -el problema ppal es que se cicla el rru despues de alguna falla de fza o alguna actualización. -Con el comando lmclist, se ve el sw instalado, siento el del slot 1 el boot o arranque(se ve en la columna type), y los demás del tipo app del mismo radio modulos etc. - el proceso del rru es primero bootea y despues carga los modulos para ejecutar las funciones asignadas. - el problema en si es que se cicla en el modo boot( el led de status queda con .5hz) y no arranca no pasa al modulo de sw, esto se corrige borrando el modulo que tiene el estado working y del tipo applic.
