IP Commands
fraglimit
A number between 1 and 1024.
Represents the maximum number of IP packet fragments waiting for
completion.
Generally the fragmentation limit is 64.
By limiting the fragmentation limit the depletion of the buffer is
avoided.

OPTIONAL
defragmode
Define which packets are reassembled under which circumstances.
Choose between:
Choose between:
•
normal
Packets to be forwarded will not be reassembled.
Packets with local destination, i.e. destined for the Speed-
Touch™, are reassembled.
Packets to be forwarded will not be reassembled.

Touch™, are reassembled.
•
always
Packets are always reassembled.
Packets are always reassembled.
•
nat
Same behaviour as normal except for packets to be forwarded
through the Network Address Translation (NAT) engine.
Packets on which address translation is performed are reas-
sembled as the NAT engine requires the entire packet.

OPTIONAL
addrcheck
Set the level of IP address checks.
Choose between:
Choose between:
•
off
No address checking is performed.
For advanced users only; in normal circumstances there
should always be some kind of address checking.

•
own
Minimum level of checking.
Only the address configuration on the SpeedTouch™ is
checked.
Minimum level of checking.
Only the address configuration on the SpeedTouch™ is

•
static
Checking of the address configuration of the SpeedTouch™
and also of traffic: addresses of incoming packets; this checking
is related to constants (e.g. an address may not be entirely
composed of one‘s or zero‘s).

•
dynamic
Besides the address configuration of the SpeedTouch™ itself,
and besides the checking of traffic on a constants level, addi-
tional checking is performed on the IP addresses that are
determined by the configuration, more specifically by the
network.

OPTIONAL
mssclamping
Disable (off) or enable (on) mss clamping for low mtu interfaces.
Mss clamping assures that the size of a TCP packet never exceeds
the available mtu of the outgoing interface.
It is recommended not to disable this parameter.
