    Hi Guys,

     

    I would like to know, how can I enable DHCP snooping MAC address verification in Juniper EX switch.

     

    The feature is explained by Cisco in the link http://www.cisco.com/c/en/us/td/docs/switches/lan/catalyst6500/ios/12-2SX/configuration/guide/book/snoodhcp.html#wp1141445

     

    Regards,

    Hi,

    Once we opened a case to JTAC EX Support and they said its automatically done by the ARP inspection (DAI).

    http://kb.juniper.net/InfoCenter/index?page=content&id=KB10960&actp=search&smlogin=true

    We closed the case , but we remained unconvinced.
    If you're juniper employee I'll send you by private message the name of the juniper JTAC contact so you can ask him .

    Hello 

     

    We also have the same problem.

     

    The problem is also discussed in topic http://forums.juniper.net/t5/Ethernet-Switching/DHCP-snnoping-verify-hardware-on-Juniper-EX-Switches/td-p/285095 . But no usable solution was proposed. 

     

    Sometimes DHCP snooping hardware verification is confused with ARP inspection. It is completely different than ARP inspection. It is a required feature in order to have a reliable DHCP based structure.

     

    Many other vendors have this feature. Hope Juniper adds to Junos too.
