    Default setting for a Cisco switch port




      I am just tryin to find out what is the default setting for a cisco switch port when it is new out of the box, I though it was dynamic desirable.


      I loaded up packet tracer and I had the following output from a 2960 switch




      Switch#show interfaces fastEthernet 0/1 switchport

      Name: Fa0/1

      Switchport: Enabled

      Administrative Mode: dynamic auto

      Operational Mode: down

      Administrative Trunking Encapsulation: dot1q

      Operational Trunking Encapsulation: native

      Negotiation of Trunking: On

      Access Mode VLAN: 1 (default)

      Trunking Native Mode VLAN: 1 (default)

      Voice VLAN: none

      Administrative private-vlan host-association: none

      Administrative private-vlan mapping: none

      Administrative private-vlan trunk native VLAN: none

      Administrative private-vlan trunk encapsulation: dot1q

      Administrative private-vlan trunk normal VLANs: none

      Administrative private-vlan trunk private VLANs: none

      Operational private-vlan: none

      Trunking VLANs Enabled: ALL

      Pruning VLANs Enabled: 2-1001

      Capture Mode Disabled

      Capture VLANs Allowed: ALL

      Protected: false

      Appliance trust: none




      As you can see from the out port Administrative mode is set to DYNAMIC AUTO.


      Is auto the default setting or is there no definate default setting for a switch port and does this mean it will vary on diffrent models of cisco switches.



      Hope this made sense look forward to your replies.
