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.
