Analisis de red lan general

[Jcorniel]

Buenos dias, espero se encuentren muy bien.

En mi trabajo me mandaron a realizar un analisis completo general de red. Ya que perciben de un tiempo para aca lentitud con algunos sistemas puntualmente.

Que programa me recomiendan utilizar el cual sea facil de interpretar y de resultados exactos.

Por otro lado, quisiera comentarles que usarmos Solardwinds para el monitoreo de los nodos, switch y demas dispositivos de red.

Me indican que revise el Switch Core, ya que todo llega alli,

Por favor guienme, la estructura es muy grande y bueno estoy comenzando en esto de las redes.

Por donde comenzar?

Agradeciendo su acostumbrado apoyo y su pronta respuesta!

[Julio E. Moisa]

Hola Jose,

Para realizar un estudio de la red, debes considerar varios factores, no es un trabajo tan facil dependiendo del tamaño de la red, si hablamos de una herramienta te recomiendo: LiveAction o tambien puedes verificar con Solarwinds.

Factores a revisar:

- Diseño fisico de la red 

- Diseño de capa 2 y capa 3

- CPU de equipos de red 

- Modelos antiguos de equipos podrían generar congestión, lentitud o cuellos de botella

- Cableado, ya que puede originar colisión de paquetes, intermitencia en los servicios o cambios en las topologias logicas. 

- Configuraciones

- Traceroutes o ping para ver los tiempos de respuesta en los saltos.

Espero te sea útil

:-)

Gracias Julio por tu acostumbrado apoyo,

Quisiera saber si hay alguna herramienta que me permita ver de donde vienen las fallas, ya que use wireshark para tratar de monitorear el trafico en la red. Pero no es tan practico ver los resultados.
La lentitud se presenta de un tiempo para aca , con respecto a los sistemas donde el usuario ingresa. Los cuales se alojan en los servers que estan aqui en nuestro data center, es decir en la propia LAN.

Hola

Siempre un gusto Jose, si deseas conocer la experiencia del usuario hacia una determinada aplicacion, puedes utilizar appneta.

Espero te sirva

Hola Julio, espero estes bien. Disculpa por no contestar a tiempo.

Por otro lado, uno de los sintomas que presenta el sw core, es los tiempos de respuestas hacia las interfaces Vlans creadas.

Tal como comente, hay una lentitud desde el usuario a algunos sistemas  alojados en los servers en esa vlan,

El detalle es que al realizar Ping desde un pc hacia la direccion ip del server donde se aloja el sistema, los tiempos se mantienen en 1ms estable.

Cuando haces ping a las interfaces de las vlans empiezan a variar los tiempos.

Que pudiera ser lo que me da esos tiempos de respuestas a estas interfaces Vlan, cabe destacar que tenemos en el swcore configurado VTP modo server, es decir desde alli se gestionan todas las vlans. El comportamiento de ping variable es en todas las interfaces vlans que se usan como gateway de usuario y servers.

Ejemplo:

172.20.5.1 ---> Interface vlan para server

172.20.12.1 ---> Interface vlan para usuarios.

Por favor me podrias orientar..?

Atento!

[Julio E. Moisa]

Hola,

Revisa si el spanning tree esta funcionando correctamente, revisa si la VLAN de servidores ha tenido cambios recientemente. 

show spanning-tree vlan <tu vlan> detail

Busca algo que diga topology changes y ahi te aparecera la ultima vez que hubo un cambio, si es un tiempo reciente, te puede indicar que hay algo que esta afectando. 

Esta la computadora donde haces ping en el mismo switch donde esta conectado el servidor? basicamente el default gateway (en este caso la interface vlan) es utilizada para comunicacion con otras redes, puedes revisar el cableado hace el switch core.

Saludos 

[Jcorniel]

Hola Julio,

Mañana cuando este en la empresa tipeare los comandos para revisar el Spánning Tree tal como comentas, y te informare los resultados.

El problema es que no hemos hecho cambios recientes. Fue de pronto.

El Pc donde hago ping hacia la vlan, esta conectado al SwCore, el servidor esta conectado en un switch a parte que va tambien conectado al Core por un puerto troncal y configurado Portchannel.

Tal como te comente , el comportamiento es en todas las interfaces vlan gateway cuando se les hace ping. Entre equipos no hay ese inconveniente.

[Jcorniel]

Estimado, este fue el resultado del comando aplicado, pero no logro ver si hay alguna afectacion, lo aplique solo en dos vlan ,la de server y una de las de usuarios;

Gracias Jose,

esta vlan 5 ha tenido varios cambios y el ultimo hace practicamente 2 días, aunque solo apagar un puerto puede generar un cambio de topologia, considero que hay muchos cambios y en poco tiempo. 

EdAdmin-P01#show spanning-tree vlan 5 detail

VLAN0005 is executing the ieee compatible Spanning Tree protocol
Bridge Identifier has priority 24576, sysid 5, address 0016.4744.5280
Configured hello time 2, max age 20, forward delay 15
We are the root of the spanning tree
Topology change flag not set, detected flag not set
Number of topology changes 1861 last change occurred 1d22h ago
from GigabitEthernet5/0/27
Times: hold 1, topology change 35, notification 2
hello 2, max age 20, forward delay 15

Ejecutar un debug despues de horas de oficina puede ser sugerido para ver si hay algun cambio en la topologia:

debug spanning-tree events

Si es asi, es de revisar si algo puede estar generando problemas a nivel de capa 2. Podria haber un loop.

Saludos 

[Jcorniel]

Pregunta: 

1-  A parte de apagar un puerto que pueda generar un cambio en la topologia, que otros factores pueden generar cambios?

2- Es decir lo que se ve alli de los cambios son todos los cambios que se han realizado en esa vlan?

3- Me indica que la interface GE5/0/27 es la interfaz donde se han realizado todos estos cambios?

4- Al ejecutar el comando debug spanning-tree events, donde veria los resultados, o que resultados me deberia traer? Es como activar terminal monitor? 

5- Un loop podria ser un mismo cable conectado en el mismo switch?

Atento a tus comentarios estimado!

[Julio E. Moisa]

1-  A parte de apagar un puerto que pueda generar un cambio en la topologia, que otros factores pueden generar cambios? Si, otros pueden ser un loop, mala configuración, intermitencia en un cable, etc. 

2- Es decir lo que se ve alli de los cambios son todos los cambios que se han realizado en esa vlan? Es correcto. 

3- Me indica que la interface GE5/0/27 es la interfaz donde se han realizado todos estos cambios? Si, que hay conectado en ese puerto?

4- Al ejecutar el comando debug spanning-tree events, donde veria los resultados, o que resultados me deberia traer? Es como activar terminal monitor? Eso lo veras en pantalla, es similar a terminal monitor, no es recomendable que habilites esto durante horas de operacion porque puede requerir muchos recursos de CPU, para deshabilitarlo solo escribe en el modo privilegiado: u all.

5- Un loop podria ser un mismo cable conectado en el mismo switch? Es correcto. 

[Jcorniel]

Julio, esto es lo que esta conectado al puerto;

Current configuration : 266 bytes
!
interface GigabitEthernet5/0/27
description Trunk AP_Congelados_Embutidos
switchport trunk encapsulation dot1q
switchport trunk pruning vlan 2-230
switchport mode trunk
storm-control broadcast level 30.00 15.00
storm-control multicast level 30.00 15.00
end

Por lo que veo es un puerto troncal que conecta a otra localidad, realmente no se si esto es real, ya que esas localidades ciertamente van conectadas por troncales y APs ubiquitti pero en otro switch, no van directamente conectadas a este swcore. Por lo que tendre que investigar.

Con respecto al debug, me da temor activarlo ya que de por si el swcore ya presenta altos consumos de memoria y cpu, lo voy a intentar a ver que observo.

Con respecto a un posible loop, tendre que buscar la manera de detectar esta falla que es fisica..

Ahora en el resto del comando para ver el spanning-tree de esta vlan, notaste algo mas fuera de lo comun?

Tengo ganas de probar apagando esa interfaz a ver si mejoran  los tiempos de respuestas, que me dices?
