swCpuAclIpTCPFlagBitMask

Module: ACLMGMT-MIB

OID (symbolic): ACLMGMT-MIB::swCpuAclIpTCPFlagBitMask

OID (numeric): 1.3.6.1.4.1.171.12.9.4.2.1.15

Node type: OBJECT-TYPE

Type: INTEGER

Access: read-create

Description: A value which indicates the set of TCP flags that this entity may potentially offer. The value is a sum of flag bits. This sum initially takes the value zero. Then, for each flag, L is added in the range 1 through 6, for which this node performs transactions where 2^(L - 1) is added to the sum. Note that values should be calculated accordingly:

Flag functionality 6 urg bit 5 ack bit 4 psh bit 3 rst bit 2 syn bit 1 fin bit For example, if you want to enable urg bit and ack bit, you should set value 48{2^(5-1) + 2^(6-1)}.

What is swCpuAclIpTCPFlagBitMask?

This OID stores a numeric value (0-63 integer range) representing a bitmask of which TCP flags are relevant to the ACL rule—calculated as the sum of powers of 2 for each flag. Network engineers use this to precisely specify which TCP control bits must be examined, such as value 2 (SYN only), value 16 (ACK only), or value 18 (SYN and ACK combined). For example, setting this to 2 means only the SYN flag matters in the match, so the ACL triggers on new connection attempts but ignores the state of other flags.
