MAC ADDRESS GENERATOR UNICAST MAC
This ARP Request packet is a unicast packet with a destination MAC address of another device on the network. Wa_audience: "emtaudience:business/btssbusinesstechnologysolutionspecialist/developer/fpgaengineer", Symptom: A Nexus 9000 switch may occasionally generate or receive an ARP Request that refreshes an existing ARP entry. Wa_curated: "curated:donotuseinexternalfilters/recommended", Wa_primarycontenttagging: "primarycontenttagging:intelfpgas/intelprogrammabledevices/intelagilexfpgasandsocfpgas", A Unicast MAC address frame is only sent out to the interface which is assigned to a specific NIC and hence transmitted to the single destination device. A MAC (Media Access Control) address is a unique identifier assigned to most network adapters or Network Interface Cards (NICs) by the manufacturer for. Wa_emtcontenttype: "emtcontenttype:designanddevelopmentreference/developerguide/developeruserguide,emtcontenttype:designanddevelopmentreference/developerguide/developerreferenceguide", The Unicast MAC address represents the specific NIC on the network. If the corresponding bit is set to one, the unicast frame is said to have passed the hash filter otherwise, the frame has failed the hash filter. A value of 0 selects Bit 0 of the selected register, and a value of 111111 binary selects Bit 63 of the Hash Table register.
It uses the upper ten bits of the CRC of the received destination address to index the content of the hash table. In hash filtering mode, the filter performs imperfect filtering for unicast addresses using a 256‑bit hash table. The MacAddr32‑MacAddr127 addresses do not have mask control and all six bytes of the MAC address are compared with the received six bytes of DA. This enables group address filtering for the DA. For MacAddr1–MacAddr31 addresses, you can mask each byte during comparison with the corresponding received DA byte. Default MacAddr0 is always enabled, other addresses MacAddr1–MacAddr127 are selected with an individual enable bit. The filter compares all 48 bits of the received unicast address with the programmed MAC address for any match.
Up to 128 MAC addresses for unicast perfect filtering are supported.
