VLAN and switchport trunk question

257 Views
Last Modified: 2016-09-07
There is Cisco 8-port catalyst 3560C and someone configured to connect a Ruckus R500. When I did a sh run in the switch, I found there was a line below and did not see list of vlans. why it was configured?

VLAN internal allocation policy ascending

Also, when I did sh vlan, there were list of default vlans plus vlans that was configured and interfaces g0/2 to g/08 was on default vlan 1. and did not find interface g0/1 assigned to any vlan

But when I did sh run int g0/1, the following was shown.
switchport trunk encapsulation dot1q
switchport mode trunk

Could someone please help to share your comment on why the switch configured?

Below is the configuration:
spanning-tree mode pvst
spanning-tree extend system-id
