tnAceIPv4TcpSyn
Module: TN-ACL-MIB
OID (symbolic): TN-ACL-MIB::tnAceIPv4TcpSyn
OID (numeric): 1.3.6.1.4.1.868.2.5.3.1.1.5.7.1.25
Node type: OBJECT-TYPE
Type: TruthValueOrAny
Access: read-write
Description: Specify the TCP 'Synchronize sequence numbers' (SYN) value for this ACE. 0: TCP frames where the SYN field is set must not be able to match this entry. 1: TCP frames where the SYN field is set must be able to match this entry. Any: Any value is allowed ('dont-care').
What is tnAceIPv4TcpSyn?
Filters a TCP ACE by the SYN (synchronize sequence numbers) flag: matches only new-connection packets with SYN set, only packets without it, or any to ignore the flag; commonly used to rate-limit or block new TCP connection attempts.
Examples
Walk all instances (SNMPv2c):
snmpwalk -v2c -c public <target> 1.3.6.1.4.1.868.2.5.3.1.1.5.7.1.25 snmpwalk -v2c -c public <target> TN-ACL-MIB::tnAceIPv4TcpSyn
Get a specific instance (index 1):
snmpget -v2c -c public <target> 1.3.6.1.4.1.868.2.5.3.1.1.5.7.1.25.1 snmpget -v2c -c public <target> TN-ACL-MIB::tnAceIPv4TcpSyn.1
Set instance 1 (SNMPv2c):
snmpset -v2c -c private <target> 1.3.6.1.4.1.868.2.5.3.1.1.5.7.1.25.1 s <value>
