Session & Buffer Question

For each session, how many buffers are created? I think two 64kB buffers (TX & RX) are created per session, but my friend is telling me only one 64kB buffer is created per session. If you know the correct answer, please let me know.

Hi @Iluvnetwork

 Why do you think that ? Did you get this from any doc? 

I think both of you may be wrong. What devices have actually is Buffer pool:

There are six buffer pools:

  • Small—104 bytes buffers

  • Middle—600 byte buffers

  • Big—1524 byte buffers

  • VeryBig—4520 byte buffers

  • Large—5024 byte buffers

  • Huge—18024 byte buffers

You can use the command "show buffers" and you even control buffer size with the command "buffers small initial 250"

Cisco has a full explanation here:
