me1200AclAceIpv4TcpFlagSyn
Module: ME1200-ACL-MIB
OID (symbolic): ME1200-ACL-MIB::me1200AclAceIpv4TcpFlagSyn
OID (numeric): 1.3.6.1.4.1.9.9.815.1.17.1.2.1.2.1.1.721
Node type: OBJECT-TYPE
Type: ME1200AclAceFlagOpcode
Access: read-write
Description: Indicates how a IPv4 TCP packet's 'Synchronize sequence numbers' field (SYN) is to be compared. The value 0 means any SYN value is allowed (don't-care field), value 1 means SYN is not equal one (FIN field isn't set) and value 2 means SYN is equal to one (FIN field is set). This object can only be configured if FrameType is ipv4(5) and Ipv4ProtocolType is tcp(6).
What is me1200AclAceIpv4TcpFlagSyn?
Checks the IPv4 TCP SYN flag ('synchronize sequence numbers'): 0 ignores it, 1 matches SYN not set, and 2 matches SYN set; commonly used to isolate new connection attempts, e.g. for rate-limiting inbound SYN floods.
