    I'm putting together a layer 3 ACL to block VRRP traffic.

    It's all working correctly but I cannot block gratuitous ARP even though the layer 2 ACL looks fine. See below:

    [hpvsr1-acl-mac-FhrpIsolation]display acl mac name FhrpIsolation
    MAC ACL named FhrpIsolation, 2 rules,
    ACL's step is 5
    rule 1 deny type 0806 ffff source-mac 0000-5e00-0100 ffff-ffff-ff00 dest-mac 0000-0000-0000 ffff-ffff-ffff
    ^^^^ ARP block rule ^^^^^
    rule 1 deny source-mac 0000-5e00-0100 ffff-ffff-ff00 (8863 times matched)
    ^^^^ VMAC block rule ^^^^^^

    <hpvsr1>display packet-filter statistics interface GigabitEthernet 2/0 outbound
    Interface: GigabitEthernet2/0
    Outbound policy:
    IPv4 ACL FhrpIsolation
    From 2023-03-04 10:37:59 to 2023-03-04 12:53:19
    rule 0 deny 112 destination 224.0.0.18 0
    rule 5 permit ip
    Totally 0 packets permitted, 0 packets denied
    Totally 0% permitted, 0% denied

    MAC ACL FhrpIsolation
    From 2023-03-04 10:37:59 to 2023-03-04 12:53:19
    rule 0 deny type 0806 ffff source-mac 0000-5e00-0100 ffff-ffff-ff00 dest-mac 0000-5e00-0100 ffff-ffff-ff00
    rule 1 deny source-mac 0000-5e00-0100 ffff-ffff-ff00
    Totally 0 packets permitted, 0 packets denied
    Totally 0% permitted, 0% denied

    IPv4 default action: Permit
    From 2023-03-04 10:37:59 to 2023-03-04 12:53:19
    Totally 0 packets

    MAC default action: Permit
    From 2023-03-04 10:37:59 to 2023-03-04 12:53:19
    Totally 0 packets

    Has anyone successfully been able to block ARP Packets with a MAC ACL?

    There doesn't appear to be away to filter this like you would on Cisco.

    Cheers
