Arp Static - H3C s3100 series Command Manual

Parameters
None
Description
Use the arp restricted-forwarding enable command to enable ARP restricted forwarding so that the
legal ARP requests received from the specified VLAN are forwarded through configured trusted ports
only, and the legal ARP responses are forwarded according to the MAC addresses in the packets, or
through trusted ports if the MAC address table contains no such destination MAC addresses.
Use the undo arp restricted-forwarding enable command to disable ARP restricted forwarding.
By default, ARP restricted forwarding is disabled.
Note that among S3100 series switches, only S3100-EI series switches support the two commands.
