DGS-3130 Layer 3 Stackable Managed Switch CLI Reference Guide Command Default Level Level: 12. Usage Guideline This command is used to filter DHCPv6 server message based on sender's IP address. If the match ipv6 accesslist command is not configured, all server messages are bypassed. An access list is configured by the ipv6 access-list command. Example This example shows how to create a DHCPv6 guard policy and matches the IPv6 addresses in the access list named list1. Switch# configure terminal Switch(config)# ipv6 dhcp guard policy dhcp_filter1 Switch(config-dhcp-guard)# match ipv6 access-list list1 Switch(config-dhcp-guard)# 23-4 ipv6 dhcp guard attach-policy This command is used to apply a DHCPv6 guard policy on the specified interface. Use the no form of this command to remove the binding. ipv6 dhcp guard attach-policy [POLICY-NAME [vlan {add | remove} VLAN-ID-LIST]] no ipv6 dhcp guard attach-policy Parameters POLICY-NAME (Optional) Specifies the DHCPv6 guard policy name. vlan add VLAN-ID-LIST (Optional) Adds VLANs to be inspected. If no VLAN specified, all VLANs will be inspected. vlan remove VLAN-ID-LIST (Optional) Removes VLANs to be inspected. Default By default, this option is disabled. Command Mode Interface Configuration Mode. Command Default Level Level: 12. Usage Guideline This command is used to apply a DHCPv6 policy to an interface. DHCPv6 guard policies can be used to block DHCPv6 server messages or filter server messages based on sender IP address. If the policy name is not specified, the default policy will set the device's role to client. Example This example shows how to apply the DHCPv6 guard policy "pol1" to ethernet 1/0/3. 252
