Administration Commands
define_tr_port, define_ethernet_port, define_fddi_port
One of the activation limit parameters, inb_link_act_lim, out_link_act_lim,ortot_link_act_lim, was not
set to a valid value.
INVALID_MAX_IFRM_RCVD
The max_ifrm_rcvd parameter was not set to a valid value.
HPR_NOT_SUPPORTED
A reserved parameter was set to a nonzero value.
DLUR_NOT_SUPPORTED
The implicit_dspu_services parameter was used to request a service that is not supported.
PU_CONC_NOT_SUPPORTED
The implicit_dspu_services parameter was used to request a service that is not supported.
INVALID_IMPLICIT_UPLINK
The implicit_uplink_to_en parameter was not set to a valid value.
State Check
If the command does not execute because of a state error, SNAplus2 returns the following parameters:
primary_rc
STATE_CHECK
secondary_rc
Possible values are:
PORT_ACTIVE
The specified port cannot be modified because it is currently active.
DUPLICATE_PORT_NUMBER
A port with the number specified in the port_number parameter has already been defined.
Other Conditions
Appendix A, Common Return Codes from snapadmin Commands, lists combinations of primary and secondary
return codes that are common to all commands.
2.61.4 Incoming Calls
If you are configuring a port that accepts incoming calls (as defined by the tot_link_act_lim, inb_link_act_lim,
and out_link_act_lim parameters), there is generally no need to define an LS to use for these calls; SNAplus2
will dynamically define an LS when the incoming call is received. However, if the incoming calls are from a
host computer that supports dependent LUs or from a downstream computer using PU concentration, you need to
explicitly define an LS because the LS definition includes the name of the PU associated with the dependent LUs
or the name of the downstream PU.
When an incoming call arrives at the port, SNAplus2 checks the MAC and SAP addresses specified on the call
against the addresses specified for link stations defined on the port (if any) to determine if an LS has already been
defined for the call. If the MAC / SAP address pair does not match the MAC / SAP address pair specified on any
of these link stations, an LS is dynamically defined. To ensure that the explicit LS definition (including the required
PU name) is used, ensure that both the MAC and SAP addresses defined for this LS match the addresses that are
supplied by the host or the downstream computer on the incoming call.
