| dosDefenseDebugMode |
1.3.6.1.4.1.207.8.4.4.4.143.2 |
| The debugging options enabled for DoS defense. Output goes
to the asynchronous port or telnet session that enabled
debugging.
The bit 'None(0)' indicates that no debugging is enabled.
The bit 'Attack(1)' indicates that information about the
start and finish of attacks is displayed.
The bit 'Packet(2)' indicates that a hexadecimal dump of
the IP header of all suspect packets is displayed.
The bit 'Diagnostics(3)' indicates that additional
debugging and diagnostic messages may be displayed. |

| dosDefenseThreshold |
1.3.6.1.4.1.207.8.4.4.4.143.4.1.4 |
| The threshold, in packets per second, at which an
attack is deemed to be in progress.
If dosDefenseAttackType is SYNFlood(1), a value of 0 means
no threshold has been set and the default thresholds apply.
An attack is suspected when the SYN:ACK ratio exceeds 2:1
above 20 packets per second, in any one-second interval.
An attack is in progress when the SYN:ACK ratio exceeds 3:1
above 20 packets per second, in any one-second interval, or
an attack is suspected more than once within a
dosDefenseBlockTime interval.
If dosDefenseAttackType is Smurf(3), a value of 0 means
the filter will block all broadcast ICMP requests.
A threshold greater than 0 will block after that number of
ICMP requests are received in a 1 second interval. |

1.3.6.1.4.1.207.8.4.4.4.143.4.1.5 |
| The time, in seconds, that must elapse after the last
malicious packet is seen, before an attack is deemed
to have finished and the port stops blocking traffic.
If dosDefenseAttackType is SYNFlood(1), it is also
the maximum time an attack is suspected before it
returns to a state of no attack. |

1.3.6.1.4.1.207.8.4.4.4.143.4.1.7 |
| If dosDefenseAttackType is Land(6), the type of port.
For other values of dosDefenseAttackType, this object
returns notapplicable(0).
A device connected to a client(1) port should have an IP
address in the local subnet, and be the original source or
ultimate destination of packets transiting the network.
Incoming packets should have a source address in the local
subnet. Outgoing packets should have a destination address
in the local subnet.
A gateway(2) port is connected directly to a gateway device
attached to external networks. Apart from a small number of
packets from the gateway device itself, all packets arriving
at the gateway port should be from other subnets. Incoming
packets should have a source address not in the local
subnet. Outgoing packets should have a destination address
not in the local subnet. |

1.3.6.1.4.1.207.8.4.4.4.143.4.1.8 |
| If dosDefenseAttackType is Smurf(3), the subnet address
is used to determine the local broadcast address.
If dosDefenseAttackType is Land(6), the subnet address
used to determine which addresses are local or remote.

is used to determine the local broadcast address.
If dosDefenseAttackType is Land(6), the subnet mask
used to determine which addresses are local or remote.

| dosDefenseAttackState |
1.3.6.1.4.1.207.8.4.4.4.143.4.1.10 |
| Whether or not an attack is currently in progress on the
port.
None(0) means no attack is in progress.
If dosDefenseAttackType is SYNFlood(1), Suspected(1)
means a SYN Flood attack is suspected. A threshold has
not been set, and the default threshold of a SYN:ACK
ratio of 2:1 above 20 packets per second has been
reached.
If dosDefenseAttackType is PingOfDeath(2), Teardrop(5)
or Land(6), Suspected means that some suspect packets
have been received but have not yet been analysed to
determine if an attack exists.
InProgress(2) means an attack is in progress. |
