To reject all incoming VCCs, select Reject all incoming VCCs and then select the Submit button.


LECS Set Stop Accepting VCCs

The Operator Console options modify the current LE services and take effect immediately. These options do not modify the static memory of the router and are lost on the next reload of the MSS Server.

Use the Set Stop Accepting VCCs option to move the LECS into a state where it rejects all incoming VCCs. You should put the LECS in such a state before creating or deleting ELANs, policies, etc. Otherwise, changing these other structures could cause a client to issue two identical configuration requests, but be assigned to different LESs with each request, because the modifications changed the LECS databases between configuration requests.

To reject all incoming VCCs, make sure Reject all incoming VCCs is selected and then select the Submit button.

To start accepting VCCs, deselect Reject all incoming VCCs and select the Submit button.


LECS Set Trace Mask

The Operator Console options modify the current LE services and take effect immediately. These options do not modify the static memory of the router and are lost on the next reload of the MSS Server.

Use the Set Trace Mask option to change the "trace mask". The trace mask and trace value are used by the LECS to determine over which VCCs packet tracing should be active. For each VCC, the LECS compares the logical AND of the trace value and the trace mask with the logical AND of the calling ATM address and the trace mask. If the resulting bit strings are identical, then the LECS should perform packet tracing on that VCC. To activate packet tracing over all VCCs, use a mask of all zeros.

Packet tracing over particular VCCs is indicated by using a more specific trace mask and trace value. Packet tracing must also be enabled for the LECS subsystem through the ELS console or configuration.

ATM trace mask:

Valid values: Any 20 hexadecimal bytes that are not an actual ATM address

Default value: FF.FF.FF.FF.FF.FF.FF.FF.FF.FF.FF.FF.FF.FF.FF.FF.FF.FF.FF.FF

To set the trace mask, enter the trace mask value and then select the Submit button.


LECS Set Trace Value

The Operator Console options modify the current LE services and take effect immediately. These options do not modify the static memory of the router and are lost on the next reload of the MSS Server.

Use the Set Trace Value option to change the "trace value". The trace mask and trace value are used by the LECS to determine over which VCCs packet tracing should be active. For each VCC, the LECS compares the logical AND of the trace value and the trace mask with the logical AND of the calling ATM address and the trace mask. If the resulting bit strings are identical, then the LECS should perform packet tracing on that VCC. To activate packet tracing over all VCCs, use a mask of all zeros.

Packet tracing over particular VCCs is indicated by using a more specific trace mask and trace value. Packet tracing must also be enabled for the LECS subsystem through the ELS console or configuration.

ATM trace value:

Valid values: Any ATM address

Default value: 00.00.00.00.00.00.00.00.00.00.00.00.00.00.00.00.00.00.00.00

To set the trace value, enter the trace value and then select the Submit button.


LECS Set Validate

The Operator Console options modify the current LE services and take effect immediately. These options do not modify the static memory of the router and are lost on the next reload of the MSS Server.

Use the Set Validate option to determine whether the LECS validates the peak cell rate of best-effort connections. If this parameter is selected, the LECS rejects connections specifying a peak cell rate greater than the line rate of the ATM interface.

Clients specifying such a peak cell rate expect that they may use more bandwidth than is available which can adversely affect network performance. Setting this parameter on may create interoperability problems with clients exhibiting this behavior.

To validate best effort peak cell rate, select validate best effort peak cell rate and then select the Submit button.


LECS Set VCC Idle Time

The Operator Console options modify the current LE services and take effect immediately. These options do not modify the static memory of the router and are lost on the next reload of the MSS Server.

Use the Set VCC Idle Time option to set the VCC idle time of the LECS.

VCC idle time:

Valid values: 3 to 43,200 seconds

Default value: 60

To set the idle time, enter the time and then select the Submit button.

The Operator Console options enable you to monitor and control operational LE services. These options modify the current LE services and take effect immediately. They do not modify the static memory of the router and are lost on the next reload of the MSS Server.

Use the Create option to create a LES-BUS from the active configuration. You must have previously defined the LES-BUS using the LE SERVICES option in the router configuration - network function. To create a LES-BUS either:

Select the Submit button.


LES Delete LES-BUS

The Operator Console options enable you to monitor and control operational LE services. These options modify the current LE services and take effect immediately. They do not modify the static memory of the router and are lost on the next reload of the MSS Server.

Use the Delete option to stop the LES-BUS and remove it from the active configuration. (The LES-BUS definition remains in static RAM). If you delete a LES-BUS and you then want to start the LES-BUS, without restarting the MSS Server, you must select the Create option.

To delete the LES/BUS, select yes and then select the Submit button.


LES Restart LES-BUS

The Operator Console options enable you to monitor and control operational LE services. These options modify the current LE services and take effect immediately. They do not modify the static memory of the router and are lost on the next reload of the MSS Server.

Use the Restart option to restart the LES-BUS using either the configuration saved in static RAM or the configuration built in dynamic RAM.

To restart using the dynamic configuration, select T5 (using config parms in Talk 5).

To restart using the static configuration, select T6 (using config parms in Talk 6).

Select the Submit button.


LES Set BUS-Monitor Duration of Sample

The Operator Console options enable you to monitor and control operational LE services. These options modify the current LE services and take effect immediately. They do not modify the static memory of the router and are lost on the next reload of the MSS Server.

You can dynamically set the BUS-Monitor Duration of Sample. This is the time during which samples are taken, as compared to the time between samples, which is the time during which the BUS Monitor waits before taking another sample.

This option, like other Operator Console options, must be used for a LES-BUS that already exists.

Sample duration:

Valid values: 1 to 600

Default value: 10

To change the sample duration, enter the number of seconds and then select the Submit button.


LES Set BUS-Monitor Sample Rate

The Operator Console options enable you to monitor and control operational LE services. These options modify the current LE services and take effect immediately. They do not modify the static memory of the router and are lost on the next reload of the MSS Server.

Use the Set BUS-Monitor Sample Rate option to set the BUS-Monitor sample rate. The sample rate specifies the rate at which the BUS Monitor samples frames sent to the BUS during a duration of sample. A value of 10 means that 1 out of every 10 frames is sampled.

This option, like other Operator Console options, must be used for a LES-BUS that already exists. You must use the options in Router Configuration to create the LES-BUS, then Write the configuration, and Reload the Gateway to create a LES-BUS.

Sample rate:

Valid values: 1 to 1000

Default value: 10

To set the sample rate, enter the rate and then select the Submit button.
