Autonegotiation - Priority

Priority

Upon receipt of the technology abilities of the other device, both devices decide the best possible mode of operation supported by both devices. The priority among modes specified in the 2002 edition of 802.3 is as follows:

  1. 1000BASE-T full duplex
  2. 1000BASE-T half duplex
  3. 100BASE-T2 full duplex
  4. 100BASE-TX full duplex
  5. 100BASE-T2 half duplex
  6. 100BASE-T4
  7. 100BASE-TX half duplex
  8. 10BASE-T full duplex
  9. 10BASE-T half duplex

In other words, among the modes that are supported by both devices, each device chooses the one that is the topmost in this list.

Famous quotes containing the word priority:

    “It can be fairly argued that the highest priority for mankind is to save itself from extinction. However, it can also be argued that a society that neglects its children and robs them of their human potential can extinguish itself without an external enemy.”
    —Selma Fraiberg (20th century)

    “Weekend planning is a prime time to apply the Deathbed Priority Test: On your deathbed, will you wish you’d spent more prime weekend hours grocery shopping or walking in the woods with your kids?”
    —Louise Lague (20th century)
