Similarly, if you have two hosts communicating at 10MBit/s, you will only be able to capture the traffic between them if the Ethernet interface of the machine capturing traffic is configured for 10MBit/s, which is probably not the default configuration.
However, there is an enormous investment in X.25 infrastructure throughout the world, and in some regions, it continues to expand. Maximum sizes vary from 64 bytes to 4096 bytes, with 128 bytes being a default on most networks.You could have a device on your network spitting out all kinds of malformed junk but if you're sniffing via a switch type hub, you won't see it.Neither is to be confused with a switch which operates as a switch (i.e.Most new hubs are in the latter category as it is a cost effective way for manufacturers to produce hubs using the same chips as their switches.The difference from a packet sniffing point of view is that the hub based on switch technology will only forward 'clean' packets whereas a genuine hub is an electrical repeater and has no knowledge of what a packet should look like.This allows the PSN to route the each packet to its intended DTE.
X.25 relies on the underlying robustness of HDLC LAPB to get data from node to node through the Assembler/Disassembler (PAD) that organizes the asynch data streams into X.25 packets for transmission across the network.Every device after that period will certainly be a 10/100MBit (or 100MBit only) switch, probably with some exceptions.Devices that are real hubs; convenient for capturing.Side Note: This category could really be broken into hubs that are real hubs (i.e.repeaters) and hubs that are really switches with learning disabled.Both maximum packet size and packet level windowing may be negotiated between DTE’s on call set up.
