arp-cache disable
Use this command to disable the ARP cache for MAC/IP.
When the ARP cache is disabled on a VxLAN access port, OcNOS does not reply to any ARP arriving on this port from the cache. OcNOS withdraws all MAC/IPs configured/learned on this access port and removes the MAC/IP entry for this access port from the local ARP cache.
OcNOS also makes sure that on withdrawing the MAC/IP route, the MAC does not become unknown. If all routes for this MAC are being withdrawn because of this command, then OcNOS advertises a MAC-only route. This is done so that the MAC does not become unknown and only the cache functionality becomes disabled.
Use the no form of this command to enable ARP cache for MAC/IP.
Note: On enabling the cache, an IP will be in conflict, then the cache enable will fail. The conflict has to be manually removed and then the cache enabled.
