Cisco Catalyst Center Template Labs – Rest-APIs – Part 9
Hace 21 horas
Primero que nada agradecer a Narbik Kocharians y Dan Shechter por el excelente concurso de Troubleshooting que realizaron hace unas semanas (Troubleshooting Challenge lab)... Gracias a éste gané una copia de sus workbooks Advanced Routing and Switching 2.0 WB y Troubleshooting WB :) ...Ahora a trabajar en ellos para alcanzar la meta!
Bueno, uno de los Tickets que me tuvo de cabeza por un buen rato fue el número 9. Enunciaba lo siguiente:
Ticket 9
