switching

[muraripadhan]

I have flat network

There is no VLAN in this everyone is connected to Default  VLAN  

In this network most of time packet should be drop i can not ping the switches but there is  no problem with end user.

Switch#show int trunk

f0/1  802.2q native VLAN 1 

Due to all packet are going through default native valn it may causes problem or other problem

how many users u have and what configuration you are running on your switch ?

Hello,

although it is not good practice to have everything going over the default VLAN 1, it is quite a common setup, especially in smaller networks.

If you cannot ping the switch (what platform/model ?), make sure that you either have 'ip routing' enabled gobally, or the 'ip default-gateway' command configured. Basically, the IP address of your VLAN 1 interface is just like any other IP address. What do you have connected to the switch ?

Hi

Using the default vlan (vlan 1) is not a good practice and never recommended by security purposes, now if you are not able to ping the switch, you should see if the interface vlan has a correct IP address and subnet related to same prefix like the computers. 

Now what you mean about: it should be dropping packets?
