Description: Display the mask for this rule. This mask corresponds to swACLPktContRuleVarOffsetOffsetIndex1 and swACLPktContRuleVarOffsetData1.
What is swACLPktContRuleVarOffsetMask1?
This OID displays a 4-byte mask value that defines which bits of the packet data at offset 1 should be checked (1=check, 0=ignore). Engineers use this mask to ignore irrelevant bits and focus on the specific data pattern they need to match. For example, a mask of 0xFF000000 means only check the first byte, and ignore the next 3 bytes.
