Syntax
upstream <port number> map {init-maint-size-adjust <value> |
max-ranging-invitations <value> | min-req-region <value> |
ucd-grant-size <value>}
Arguments
<port number> Number of the upstream port that you want to configure. Valid
range is 1 to 4 for 1x4 modules and 1 to 6 for 1x6 modules.
init-maint-size-adjust
<value>

ucd-grant-size <value> Upstream Channel Description (UCD) grant size. After a UCD
change, this specifies the size of grant to zero (which functions as
