agentSwitchDenialOfServiceTCPFlagMode
Module: EdgeSwitch-DENIALOFSERVICE-PRIVATE-MIB
OID (symbolic): EdgeSwitch-DENIALOFSERVICE-PRIVATE-MIB::agentSwitchDenialOfServiceTCPFlagMode
OID (numeric): 1.3.6.1.4.1.4413.1.1.31.1.5
Node type: OBJECT-TYPE
Type: INTEGER
Access: read-write
Description: Enables or Disables the TCP Flag Denial of Service protection feature.
What is agentSwitchDenialOfServiceTCPFlagMode?
This read-write switch enables or disables the "TCP Flag" Denial-of-Service protection feature, which inspects the combination of TCP control flags set in a packet. Admins enable it to block packets carrying flag combinations that never occur in legitimate TCP traffic, which attackers use to probe firewalls or exploit weak stack implementations. For example, a packet with all flag bits set, a so-called Christmas-tree packet, would be filtered out by the switch when this feature is enabled.
Examples
Walk all instances (SNMPv2c):
snmpwalk -v2c -c public <target> 1.3.6.1.4.1.4413.1.1.31.1.5 snmpwalk -v2c -c public <target> EdgeSwitch-DENIALOFSERVICE-PRIVATE-MIB::agentSwitchDenialOfServiceTCPFlagMode
Get a specific instance (index 1):
