difference between TOS,TNS and TOT,TNT

Hi Pankaj,

TOS: Trunk Operating Status (what mode the port operates in; can be access or trunk)

TAS: Trunk Administrative Status (what mode the port is configured in; can be on, off, desirable or auto)

TNS: Trunk Negotiation Status (what mode DTP negotiated; can be access or trunk)

TOT: Trunk Operating Type (what encapsulation the port currently operates in; can be native, ISL or DOT1Q)

TAT: Trunk Administrative Type (what encapsulation the port is configured for; can be negotiated, native, ISL or DOT1Q)

TNT: Trunk Negotiation Type (what encapsulation DTP negotiated; can be native, ISL or DOT1Q)

Thanks go to Aninda Chatterjee from Cisco for initially providing most of this information to me.

Best regards,

Peter

DTP information for Ethernet0/0:

  TOS/TAS/TNS:                              TRUNK/DESIRABLE/TRUNK

  TOT/TAT/TNT:                              ISL/NEGOTIATE/ISL

suppose this is the output
