Parameters
number: Specifies the maximum number of TCP header-compression connections allowed, in the
range of 3 to 256.
Usage guidelines
TCP is a connection-oriented protocol and c an carry many TCP connections on one link. The
compression algorithm maintains information for each TCP header-compression connection. To
save memory resources, you can use this command to specify the maximum number of TCP
header-compression connections allowed. For example, if you specify the maximum number as 3,
packets of the fourth TCP connection are not compressed.
The maximum number of TCP header-compression connections configured on an i nterface is
inherited by all VCs of the interface. If you set a different maximum number on a VC of the interface,
the setting on the VC takes effect.
You can configure this command on an interface or PVC only after you enable IPHC without
specifying the nonstandard keyword on the interface or PVC. The configuration takes effect on an
interface or PVC after you execute the shutdown/undo shutdown command sequence on t he
interface or PVC. After you disable IPHC or re-enable IPHC with the nonstandard keyword, the
configuration is deleted.
