Hola a todos!
Soy nuevo en el foro y quiero compartir con ustedes un evento que me está sucediendo en mi CMTS ARRIS C4, tengo dos marcas de cable modem (Netgear y Motorola) y con ambos tengo el principal problema en el momento de "registrarse". Ojo que me pasa solamente en un Slot, actualmente tengo 2 en producción.
Para aquellos que saben el tema, el proceso de registro empieza con el Offline; Ranging; Ranged; IPcomplete y Registered.
Bueno, el problema pasa al llegar en el proceso de IPcomplete donde ya se le asigna una IP al cable modem pero no tiene navegacion a internet; no llega a Registered. La solución temporal y muy molestosa es reiniciando varias veces el cable modem hasta que éste tome por completo la IP CPE y tenga navegacion a internet normalmente (se reinicia manualmente o con el comando desde el CMTS "configure reset cable-modem MAC ADDRESS").
Primeramente he mudado a otro slot que tenia libre y me pasaba lo mismo, con el comando desde el CTMS "configure reset slot x" forzaba reiniciar el slot pero echaba a todos los cablemodems registrados. Volvi a colocar donde estaba y me fije algunos errores de configuracion del usptream, configuré nuevamente el Load-Balance, cambié de modulacion (QPSK a QAM-16) porque me dijeron que saturaba la banda ancha de retorno pero no se usa ni el 30%.
Ya no veo nada raro en mi configuración, sigo creyendo que es algun error de saturacion de mi downstream o que mi balanceo no está bien hecho.
Pongo a disposicion de ustedes estimados que me ayuden a ver cual puede ser el inconveniente. paso un detalle de mi configuración actual.
