Zorluk: ZorVLAN Configuration and Access Port Setup

A network engineer needs to manually configure VLAN 30 named Engineering on a Cisco Catalyst switch and assign interface GigabitEthernet0/1 as an explicit static access port belonging to VLAN 30. Place the Cisco IOS CLI configuration steps in the correct chronological order required to accomplish this configuration starting from Privileged EXEC mode.

  1. 1Switch# configure terminal
  2. 2Switch(config)# vlan 30
    Switch(config-vlan)# name Engineering
    Switch(config-vlan)# exit
  3. 3Switch(config)# interface gigabitethernet0/1
  4. 4Switch(config-if)# switchport mode access
  5. 5Switch(config-if)# switchport access vlan 30

Cevap

The correct sequence begins with entering global configuration mode ('configure terminal'), creating and naming VLAN 30 ('vlan 30' and 'name Engineering'), navigating to interface configuration mode ('interface gigabitethernet0/1'), enforcing access mode ('switchport mode access'), and assigning the port to VLAN 30 ('switchport access vlan 30').
The CLI hierarchy in Cisco IOS demands starting in Privileged EXEC mode, moving to global configuration mode, defining the VLAN object and its name, entering the target interface configuration context, defining the port mode as access, and lastly binding the port to the intended VLAN ID.

Adım Adım Çözüm

1
Execute 'configure terminal' at the Privileged EXEC prompt (Switch#).
Transitions the CLI prompt to global configuration mode (Switch(config)#).
CLI commands for creating VLANs and accessing interfaces require global configuration privileges.
2
Execute 'vlan 30', followed by 'name Engineering' and 'exit'.
Creates VLAN 30 in the VLAN database and assigns the alphanumeric label 'Engineering'.
Defining the VLAN explicitly in global configuration mode ensures proper Layer 2 broadcast domain setup and labeling.
3
Execute 'interface gigabitethernet0/1'.
Transitions the CLI prompt to interface configuration mode (Switch(config-if)#).
Interface parameters can only be altered when inside the specific interface configuration context.
4
Execute 'switchport mode access'.
Statically sets the port mode to access, disabling DTP trunk negotiation.
Best security and operational practices dictate explicit configuration of access ports rather than relying on dynamic negotiation defaults.
5
Execute 'switchport access vlan 30'.
Associates interface GigabitEthernet0/1 with VLAN 30 for untagged frame traffic.
Assigns the access interface to forward untagged traffic on VLAN 30.
