Zorluk: OrtaVLAN Configuration and Access Port Setup

A network administrator is inspecting interface configuration settings on a Cisco Catalyst switch after a user host on FastEthernet0/12 fails to communicate with devices in the target network. The output from the command `show interfaces FastEthernet0/12 switchport` indicates the following:

text
Name: Fa0/12
Switchport: Enabled
Administrative Mode: dynamic auto
Operational Mode: static access
Access Mode VLAN: 1 (default)

Which combination of interface configuration commands must the administrator execute on FastEthernet0/12 to explicitly set the port as a static access port and assign it to VLAN 45?

  1. switchport mode access
    switchport access vlan 45
    Cevap
  2. B
    switchport mode access
    switchport trunk native vlan 45
  3. C
    vlan 45
    switchport access vlan 45
  4. D
    switchport mode dynamic desirable
    switchport access vlan 45

Cevap

To configure FastEthernet0/12 as a static access port in VLAN 45, the administrator must enter interface configuration mode for FastEthernet0/12 and apply 'switchport mode access' followed by 'switchport access vlan 45'.
To configure a switch port as a static access member of a specific VLAN, Cisco IOS requires two commands under interface configuration mode: 'switchport mode access' to define the operational mode as access, and 'switchport access vlan <vlan-id>' to associate the interface with the specific VLAN ID.

Adım Adım Çözüm

1
Change interface operational mode to static access
Disables dynamic trunking negotiation attempts on the interface and hardcodes it as an access port
The 'switchport mode access' command forces the interface into static access mode.
2
Assign the interface to the designated broadcast domain
Traffic received on FastEthernet0/12 is tagged/placed into VLAN 45
The 'switchport access vlan 45' command specifies VLAN 45 as the access VLAN for untagged frames.
