IP Source guard is not working when enable mac-vlan on port (5120-SI)

[pigsign]

Hi all,

DHCP snooping + IP souce guard works well on port.

But if enable mac-vlan, IP source guard would stop work and no function.

Are there any idea about this ?

My config like below:

---

HP Comware Platform Software
Comware Software, Version 5.20, Release 1513P99

interface GigabitEthernet2/0/14
 port link-type hybrid
 undo port hybrid vlan 1
 port hybrid vlan 240 tagged
 port hybrid vlan 4 99 untagged
 port hybrid pvid vlan 4
 mac-vlan enable
 ip check source ip-address

Thanks for any help!!!~
