Table 4-31 describes the default values for each command parameter, which are based on the total
amount of memory for the device.
TCP Client Settings
Enable Client Satellite Sets client TCP compliance to the RFC 1323 standard. For more
information, see the “TCP-Over-Satellite Extensions” section on
page 4-66.
Note If you enable a client satellite, the server satellite is
automatically enabled.
Client Max Segment Size Maximum packet size sent to clients. The default is 1432 bytes.
Client Receive Buffer Size TCP receiving buffer size in kilobytes (8 to 512) for incoming TCP
packets. The default is 8.
Client Read/Write Timeout Period after which the SE times out when attempting to read or
write to the network. The default is 120 seconds.
Client Send Buffer Size TCP sending buffer size in kilobytes (8 to 512) for outgoing TCP
packets. The default is 32.
TCP Memory Limit Settings
TCP Memory Limit Low Water
Mark
The lower limit (MB) of memory pressure mode, below which
TCP enters into normal memory allocation mode. The range is
from 4 to 600.
Low—TCP does not regulate its memory allocation when the
number of pages it has allocated globally is below this number.
TCP Memory Limit High Water
Mark–Pressure
The upper limit (MB) of normal memory allocation mode, beyond
which TCP enters into memory pressure mode. The range is from
5 to 610.
Pressure—When the amount of memory allocated by TCP exceeds
this number of pages, TCP moderates its memory consumption.
This memory pressure state is exited once the number of pages
allocated falls below the low mark.
TCP Memory Limit High Water
Mark–Absolute
The absolute limit (MB) on TCP memory usage. The range is from
6 to 620.
Absolute—The maximum number of pages, globally, that TCP
will allocate.
