h3cAclEnUserIPv4String
Module: A3COM-HUAWEI-ACL-MIB
OID (symbolic): A3COM-HUAWEI-ACL-MIB::h3cAclEnUserIPv4String
OID (numeric): 1.3.6.1.4.1.43.45.1.10.2.8.2.4.3.1.7
Node type: OBJECT-TYPE
Type: OCTET STRING
Access: read-create
Description: The rule, matching IPv4 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 h3cAclEnUserIPv4String?
This OID defines a custom matching rule for IPv4 packets using hexadecimal pattern strings with byte offsets and masks. Network engineers deploy advanced packet filtering rules beyond standard ACLs to match specific header fields or payload patterns in IPv4 traffic. Example: matching a particular TCP option at byte 20 allows blocking or prioritizing traffic with unusual TCP configurations.
