accBrFiltIIEntDstMacAddrMask
Module: ACC-MIB
OID (symbolic): ACC-MIB::accBrFiltIIEntDstMacAddrMask
OID (numeric): 1.3.6.1.4.1.5.1.1.4.19.1.7
Node type: OBJECT-TYPE
Type: OCTET STRING
Access: read-write
Description:
Destination MAC Address Mask for the Filtering entry. The mask is ANDed with the Destination address to determine that part of the MAC address which is used in the filtering decision.
What is accBrFiltIIEntDstMacAddrMask?
This holds a 6-byte mask that specifies which bits of the destination MAC address are used in the filtering decision. Engineers use this mask to match ranges of MAC addresses or vendors, allowing them to block or permit entire groups of devices without listing each address individually. A mask of FF:FF:FF:00:00:00 applies the filter only to the first three octets of the destination MAC, effectively grouping devices by vendor prefix.
