Fix Recommendation

Remove the assignment of the default VLAN from all access switch ports:

OS10(config)# interface range eth1/1/4-1/1/58
OS10(conf-range-eth1/1/4-1/1/58)# switchport mode access
OS10(conf-range-eth1/1/4-1/1/58)# switchport access vlan 200

Check Contents

Review the switch configurations and verify that no access switch ports have been assigned membership to the default VLAN (i.e., VLAN 1). VLAN assignments can be verified via the “show vlan” command:

OS10# show vlan
Codes: * - Default VLAN, M - Management VLAN, R - Remote Port Mirroring VLANs,
@ - Attached to Virtual Network, P - Primary, C - Community, I - Isolated,
S - VLAN-Stack VLAN
Q: A - Access (Untagged), T - Tagged
NUM Status Description Q Ports
* 1 Inactive
30 Inactive Management VLAN
100 Inactive A Eth1/1/1
200 Inactive A Eth1/1/3-1/1/58
201 Inactive A Eth1/1/2
OS10#

If there are access switch ports assigned to the default VLAN, this is a finding.
