Zorluk: KolayInterswitch Connectivity and Trunking (802.1Q)

A network administrator needs to statically configure an interface on a Cisco Catalyst switch to act as an IEEE 802.1Q trunk link to a neighboring switch. Which interface configuration command achieves this objective?

  1. switchport mode trunkCevap
  2. B
    spanning-tree portfast trunk
  3. C
    switchport trunk native vlan 99
  4. D
    show cdp neighbors detail

Cevap

The command `switchport mode trunk` statically sets the switch interface to operate in trunking mode.
The `switchport mode trunk` command puts the interface into permanent trunking mode and initiates DTP negotiation to convert the link into a trunk link.

Adım Adım Çözüm

1
Identify the administrative requirement.
The link must be manually configured as a static 802.1Q trunk line connecting two switches.
The scenario requires an interface command that changes the port mode to permanent trunking.
2
Evaluate Cisco IOS interface mode configuration syntax.
Executing `switchport mode trunk` forces the interface to transition out of access mode into permanent 802.1Q trunking mode.
This is the standard command used to establish permanent L2 interswitch connectivity.
