Tráfico entre los VSS

Buenos días,

 

Es normal que entre dos SW conectados entre sí con la tecnología VSS es normal tanto tráfico , esto debido a que uno equipo esta como principal y el otro como BK.

 

les comparto el show ver

Hola,

Borra lo counters de las interfaces y verifica si se siguen incrementando:

clear counter <interface>

 

Que esta conectado en ambas interfaces? es el enlace entre ellos, podria ser que un dispositivo como switch de acceso tenga conexion unicamente al switch de backup y el trafico que ves sea de transito.

 

Saludos

Buenas tardes,

 

Ambas interfaces conectan  el SW core para armar  el VSS

 

saludos
