Cisco Trunk Port Configuration for Switches – Video 24 GNS3 Labs for CCNA
VIDEO 24 in the GNS3 Labs for CCNA 200-301
Here is a link to the first video in the playlist for the Complete GNS3 Labs for CCNA 200-301 Exam:
In this video we will go through how to perform cisco trunk port configuration. This will involve what vlans are allowed on the cisco trunk vlan configuration and briefly distinguish the difference between cisco trunk vs access mode. Cisco trunk configuration commands are included. Cisco trunk stetup involves specifying the allowed vlans.
I’ll include cisco trunk port configuration samples and examples. There are cisco trunk port configuration best practices for cisco switch port trunk configuration. This involves vlan pruning on cisco trunks and we will discuss the cisco trunk encapsulation methods including dot1q.
We will also look at the trunk port definition and do a trunk port configuration in a cisco switch.
PRE-CONFIG:====================
SW1:======================
conf t
hostname SW1
vlan 10
name ACCESS
exi
int vl 10
ip add 10.0.0.253 255.255.255.0
sh
SW2:======================
conf t
hostname SW2
vlan 10
name ACCESS
exi
int vl 10
ip add 10.0.0.254 255.255.255.0
sh
MIN-CONFIG-ACCESS:========
int ra gi 0/0 – 1
switchport mode access
switchport access vlan 10
PC1:======================
ip 10.0.0.1 255.255.255.0 10.0.0.253
PC2:======================
ip 10.0.0.2 255.255.255.0 10.0.0.253
PC3:======================
ip 10.0.0.3 255.255.255.0 10.0.0.254
PC4:======================
ip 10.0.0.4 255.255.255.0 10.0.0.254
DEFAULT-INTERFACE:========
default int ra gi 0/2 – 3
NEW-CONFIG:=====================
TRUNK-CONFIG:=============
int ra gi 0/2 – 3
switchport trunk encap dot1q
switchport mode trunk
switchport trunk allowed vlan 10
spanning-tree portfast trunk
do sh int tru
int ra gi 0/2 – 3
shut
switchport trunk allowed vlan all
no shut
do sh int tru
#ISL
int ra gi 0/2 – 3
switchport trunk encap isl
switchport mode trunk
switchport trunk allowed vlan 10
no sh
int ra gi 0/2 – 3
no sh
VERIFY:===================
show vlan brief
do show interface trunk
ping 10.0.0.1
ping 10.0.0.2
