IMPORTANT:
Static IPv4SG bindings that contain MAC addresses are not supported on Layer 2 Ethernet ports on
the following modules:
• HMIM-8GSW.
• HMIM-8GSWF.
• HMIM-24GSW.
• HMIM-24GSWP.
Static IPv4SG bindings that contain IP addresses or VLANs are not supported on the following
routers:
• MSR810-W.
• MSR810-W-DB.
• MSR810-LM.
• MSR810-W-LM.
• MSR810-10-PoE.
• MSR810-LM-HK.

• MSR2600-10-X1.
Static IPv4SG bindings on an interface implement the following functions:
•
Filter incoming IPv4 packets on the interface.
•
Check user validity by cooperating with the ARP attack detection feature.
You cannot configure static IPv4SG bindings on a service loopback interface.
Examples
# Configure a static IPv4SG binding on GigabitEthernet 1/0/1.
<Sysname> system-view
[Sysname] interface gigabitethernet 1/0/1
[Sysname-GigabitEthernet1/0/1] ip source binding ip-address 192.168.0.1 mac-address
