Hi Guys,
Does anyone faces this kind of issues before? Let's says assign an IP address on vlan 88 10.154.4.189 which is a free ip address on the vlan 88 address pool. But after a while, the server on this vlan 88 cannot be access and ping. Checking back the IP address 10.154.4.189 supposedly free. Some server get IP address conflict with this firewall device if assign IP address 10.154.4.189. Below is the switch port configuration. I do think firewall as layer 3, switch as layer 2 will be block from the port.
switchport access vlan 311
switchport mode access
switchport voice vlan 106
ip arp inspection trust
trust device cisco-phone
storm-control broadcast level 50.00
storm-control multicast level 50.00
auto qos voip cisco-phone
spanning-tree portfast
spanning-tree bpduguard enable
service-policy input AutoQos-4.0-CiscoPhone-Input-Policy
service-policy output AutoQos-4.0-Output-Policy
