Fix Recommendation

Configure the switch to have DHCP snooping for all user VLANs to validate DHCP messages from untrusted sources.

1. Configure user VLANs for DHCP snooping.
ICX#configure terminal
ICX(config)#ip dhcp snooping vlan 100 to 101 150

2. Configure port(s) to be trusted.
ICX(config)# interface ethernet x/x/x
ICX(config-if-e1000-x/x/x) dhcp snooping trust

Check Contents

Review switch configuration for DHCP snooping on all user VLANs.

!
ip dhcp snooping vlan 100
!
interface ethernet x/x/x
port-name toward_dhcp_srvr
dhcp snooping trust

If DHCP Snooping is not configured on user VLANs to validate DHCP messages from untrusted sources, this is a finding.
