HP Procurve 2920 ARP-PROTECT Issue
Hi All,
I am new to HP ProCurve switches, we have just bought 4 HP ProCurve J9727A Sws. I've deployed dynamic VLANs with Active Directory and NPS server. Also enable DHCP Snooping. But now I've an issue in ARP-PROTECT. When I enable this feature the network gets down.
In my scenario I've the following VLANs.
VLAN 1 (Default) for Wireless Users.
VLAN 10 for Guest Network
VLAN 11 for DMZ
VLAN 12 for Servers
VLAN 13 for MPLS for WAN
VLAN 14 for Switches
VLAN 15 for Voice / IP Phone
VLAN 16 for Untrust Finger Print devices
VLAN 17 through 22 for departments.
My UP Link ports are 23-24
Can anyone help me by giving commands to apply for maximum security.
Thanks
Regards
Faisal

Re: HP Procurve 2920 ARP-PROTECT Issue
Did you configure ports 23-24 as trusted ports?
Did you add in any non-DHCP IP addresses to the static bindings on each switch?
Did you verify each switch's static bindings to see what is in them?

Re: HP Procurve 2920 ARP-PROTECT Issue
Thanks for your kind reply. I can share with you the configurations if you can give me your meail or shall I send you in private ?
I did configure the trunk ports are trusted.
There's no static binding for non DHCP.
I didn't verify the static bindings. I simply applied the following configuration in switches. Also the DHCP Snooping is already enabled with the trusted ports.
SW1
arp-protect
arp-protect trust 19,20-24
arp-protect vlan 1-30
SW2
arp-protect
arp-protect trust 22-24
arp-protect vlan 1-30
SW3
arp-protect
arp-protect trust 23-24
arp-protect vlan 1-30
SW4
arp-protect
arp-protect trust 23-24
arp-protect vlan 1-30
Please advise what further command to be run.
Regards.
