Arp Static - H3C s3600 series Command Manual

By default, this function is disabled.
Note that:
Among S3600 series Ethernet switches, only S3600-EI series switches support this command.
Before enabling the master switch of a VRRP backup group to send gratuitous ARP packets
periodically, you need to create the VRRP backup group and perform corresponding configurations.
Refer to the part discussing VRRP in this manual for details.
Examples
# Enable the master switch of the VRRP backup group to send gratuitous ARP packets periodically.

arp static

Syntax
arp static ip-address mac-address [ vlan-id interface-type interface-number ]
arp static ip-address mac-address vlan-id (in Ethernet port view)
undo arp ip-address
View
System view, Ethernet port view
Parameters
ip-address: IP address contained in the ARP mapping entry to be created/removed.
mac-address: MAC address contained in the ARP mapping entry to be created, in the format of H-H-H.
vlan-id: ID of the VLAN to which the static ARP entry belongs, in the range of 1 to 4,094.
interface-type: Type of the port to which the static ARP entry belongs.
interface-number: Number of the port to which the static ARP entry belongs.
Description
Use the arp static command to create a static ARP entry.
Use the undo arp command to remove an ARP entry.
By default, the system ARP mapping table is empty and the address mapping entries are obtained by
ARP dynamically.
Note that:
Static ARP entries are valid as long as the Ethernet switch operates normally. But some operations,
such as removing a VLAN, or removing a port from a VLAN, will make the corresponding ARP
entries invalid and therefore removed automatically.
As for the arp static command, the value of the vlan-id argument must be the ID of an existing
VLAN, and the port identified by the interface-type and interface-number arguments must belong to
the VLAN.
Currently, static ARP entries cannot be configured on the ports of an aggregation group.
