Module: A3COM-HUAWEI-ACL-MIB
OID (symbolic): A3COM-HUAWEI-ACL-MIB::h3cAclEnUserL4String
OID (numeric): 1.3.6.1.4.1.43.45.1.10.2.8.2.4.3.1.9
Node type: OBJECT-TYPE
Type: OCTET STRING
Access: read-create
Description: The rule, matching layer 4 packets, input like this: 'RuleOffset','RuleString','RuleMask'.
RuleOffset: The value is defined by product and it indicates offset of the rule mask in the packet(unit: byte).
RuleString: The length of RuleString is defined by product. The string must be hexadecimal. The length of string must be multiple of 2.
RuleMask: The length of RuleMask is defined by product. The string must be hexadecimal. The length of string must be multiple of 2.
For example: '10','10af','ffff'.
Default value is null.
What is h3cAclEnUserL4String?
This OID contains hexadecimal match patterns for Layer 4 protocol data, enabling deep packet inspection at the transport layer. Network operators match specific TCP or UDP payload signatures to detect, block, or mark traffic from applications or attack patterns. Example: matching bytes '0xABCD' at offset 8 in UDP payloads could identify a specific proprietary protocol or malware signature.
