Configuring IP IP Forwarding
OmniSwitch AOS Release 8 Network Configuration Guide December 2017 page 15-14
When configuring a static multicast ARP entry, do not use any of the following multicast addresses:
01:00:5E:00:00:00 to 01:00:5E:7F:FF:FF
01:80:C2:XX.XX.XX
33:33:XX:XX:XX:XX
The IP address and hardware address (MAC address) are required when you add an entry to the ARP
table. Optionally, you can also specify:
• Alias. Use the alias keyword to specify that the switch acts as an alias (proxy) for this IP address.
When the alias option is used, the switch responds to all ARP requests for the specified IP address with
its own MAC address. This option is not related to Proxy ARP as defined in RFC 925.
For example:
-> arp 171.11.1.1 00:05:02:c0:7f:11 alias
• ARP Name. Use the arp-name parameter to specify a name for the permanent ARP entry.
For example:
-> arp 171.11.1.1 00:2a:90:d1:8e:10 arp-name server1
• Interface. Use the interface parameter to set the interface for the permanent ARP entry.
For example:
-> arp 171.11.1.1 00:2a:90:d1:8e:10 arp-name server1 interface Int1
Use the show arp command to display the ARP table.
Deleting a Permanent Entry from the ARP Table
Permanent entries do not age out of the ARP table. Use the no arp command to delete a permanent entry
from the ARP table. When deleting an ARP entry, you only need to enter the IP address. For example, to
delete an entry for IP address 171.11.1.1, you would enter:
-> no arp 171.11.1.1
Use the show arp command to display the ARP table and verify that the entry was deleted.
Note. As most hosts support the use of address resolution protocols to determine and cache address
information (called dynamic address resolution), it is not required to specify permanent ARP entries.
Note. You can also use the no arp command to delete a dynamic entry from the table.
