  • Path of packets...

    Hello ,

    I have this situation :
    A big network with many switches (with their own IPs).

    For example i would like to know if there are any aplication or commands (like tracert or pathping) for finding out what is the exact WAY of the packets that are going from a computer to another.

    For exemple : i have this computer 192.168.2.100 and if i ping 192.168.2.200 it has only one hop , but there are 2 swithces between them with the 192.168.2.5 and 192.168.2.6.
    Is there such a command or aplication?

    Thank you

    P.S. I am always bad in explaining what my problem is i hope i am getting understand here

    I don't any application which can do this.
    Why? a switch won't respond on packets.
    It just switch the packets unless you're the switch will route the packets to for an example an other vlan.

      Would a layer2 switch update hop count anyway as it works on frames? Wouldn't you need a router/bridge etc to do that as hop count is packets?

        AFAIK you need a L3 device to update the hopcount.
        The hopcount was exually what I ment but couldn't remember the word so quickly

          A L2 switch will not look at, change, or otherwise know anything about hop counts. A hop is a function of a router (or L3 switch). A router will decrement the TTL by one as a packet passes through it. A L2 switch has no such mechanism as it isn't routing the packet but simply forwarding it from one port to another. I know of no such program that can "count" the packets as they go through a switch and tell you how many switches the packet traveled through.
