Network to Media Resolution (ARP & NDP)

NVIDIA UFM-SDN Appliance Command Reference Guide v4.16.1

IPv4 network use Address Resolution Protocol (ARP) to resolve IP address to MAC address.

arp <ip-address> <mac-address>

no arp <ip-address> <mac-address>

Sets a static ARP entry.

The no form of the command deletes the static ARP.

Syntax Description

Notes

ipv6 neighbor <ipv6-address> <ifname> <mac-address>

no ipv6 neighbor <ipv6-address> <ifname> <mac-address>

Adds a static neighbor entry.

The no form of the command deletes the static entry.

Syntax Description

ipv6-address

IPv6 address

ifname

Management interface (i.e. eth0, eth1)

mac-address

MAC address

Default

N/A

Related Commands

arp

clear ipv6 neighbors

Notes

  • ARP is used only with IPv4. In IPv6 networks, Neighbor Discovery Protocol (NDP) is used similarly.

  • Use The no form of the command to remove static entries. Dynamic entries can be cleared via the “clear ipv6 neighbors” command.

clear ipv6 neighbors

Clears the dynamic neighbors cache.

Notes

  • Clearing Neighbor Discovery Protocol (NDP) cache removes only the dynamic entries learned and not the static entries configured

  • Use the no form of the command to remove static entries

show ipv6 neighbors [static]

Displays the Neighbor Discovery Protocol (NDP) table.

static

Filters only the table of the static entries
