How to configure DHCP Snooping functionality in Aruba MAS

The following command adds a static binding on a VLAN:

(host) ("vlan id") #dhcp-snooping-database <mac> gigabitethernet <slot/module/port> <ip_address>

The following command deletes a static binding on a VLAN:

(host) ("vlan id") #no dhcp-snooping-database <mac> gigabitethernet <slot/module/port> <ip_address>

The following command enables and configures DHCP snooping and static binding on a VLAN:

(host) (“vlan id”)# vlan-profile dhcp-snooping-profile <profile-name>

(host) (dhcp-snooping-profile “profile-name”)# enable

The following command attaches DHCP Snooping profile on the VLAN:

(host) (“vlan id”)# dhcp-snooping-profile <profile name>

Network Topology : DHCP Snooping function is enabled at a vlan level

 

The following example enables and configures DHCP Snooping on a VLAN:

 

(host) (“vlan 6”)# vlan-proifile dhcp-snooping-profile DHCP

 

(host) (dhcp-snooping-profile “DHCP”)# enable

 

 The following example attaches DHCP Snooping profile on the VLAN:

 

(host) (“vlan 6”)# dhcp-snooping-profile DHCP

 

Here's how we can verify if we have configured DHCP snooping in the manner suggested in this KB Article,


The following command displays the DHCP Snooping configuration details:

(host) (config) #show vlan-profile dhcp-snooping-profile DHCP

dhcp-snooping-profile "DHCP"
