Set Receive Buffers

Use the Set Receive Buffers option to adjust the number of private receive buffers for most interfaces. The Set Receive-Buffers option can be used to increase the receive performance of an interface. In addition, this command can be used to reduce flow control drops when the router is forwarding many packets from a fast interface to a slow interface. The effect of this command is visible when you use the Operator Console Buffer option and the List Devices option.

Attention:   Use this command only under direct instructions from your service representative.

For receive buffers:

Valid values: A decimal number from 5 to 255

Default value: Depends on the type of interface:

Maximum value: Depends on the type of interface:

Entering a value of 0 resets the interface to the default.

To set the receive buffers:

  1. Enter the interface number.

    Valid values: 0 to 7

    Default value: 0

  2. Select the Submit button.
  3. Enter the value for the receive buffers.
  4. Select Router Configuration after completing other configuration tasks.
  5. Select Write from the list of router commands.
  6. Select Write.
  7. Select Configuration and Console.
  8. Select Reload gateway and follow the instructions there.

Time of Day Host

The Time Host option sets the IP address of the RFC 868-compliant host which will be used as the time source. This host will respond to an empty datagram on UDP port 37 with a datagram containing the current time.

Note: The MSS Server has a hardware clock that maintains the date and time after router re-initialization.

For time of day host:

Valid values: Any valid IP address

Default value: 0.0.0.0

To set the time of day host, enter the IP address of the host that you are using for the time standard and then select the Submit button.


Time of Day Offset

The Time Offset option defines the time zone, in minutes, offset from GMT (Greenwich Mean Time). Note that values west of GMT are negative. For example, EST is 5 hours earlier than GMT, so the input would be -300.

Note: The MSS Server has a hardware clock that maintains the date and time after router re-initialization.

For time of day offset:

Valid values: -720 to 720

Default value: 0

To set the time of day offset, enter the number of minutes and then select the Submit button.


Time of Day Set

Use theTime Set option to set the current date and time for a router.

Note: The MSS Server has a hardware clock that maintains the date and time after router re-initialization.

To set the time of day:

  1. Enter the year.

    Valid values: Any year

    Default value: 1993.

  2. Enter a two-digit month.

    Valid values: 01 to 12

    Default value: 12

  3. Enter the date.

    Valid values: 1 to 31

    Default value: 6

  4. Enter the hour in 24-hour format.

    Valid values: 01 to 24

    Default value: 11

  5. Enter the minutes.

    Valid values: 0 to 59

    Default value: 3

  6. Enter the seconds.

    Valid values: 0 to 59

    Default value: 2

Select the Submit button.


Time of Day Sync

Use the Time Sync option to set the period, in seconds, at which the MSS Server polls the time host for the current time.

Note: The MSS Server has a hardware clock that maintains the date and time after router re-initialization.

For time of day synch:

Valid values: 0 to 2147483647 seconds

Default value: 0 which turns off polling

To set the time of day synch, enter the number of seconds and then select the Submit button.


Unpatch

Use the Unpatch option to restore the values of the patch variables entered with the Patch command to their default values. For example, you would use Unpatch Ethernet-security to restore the value of the Ethernet-security patch to its default.

The following are the supported variables you can unpatch:

Note: You must specify the complete name of the patch variable that you want to unpatch. You cannot use an abbreviated syntax for the patch name.

To reset the patch variable, enter the full variable name and then select the Submit button.


ELS Default Trace Event

Resets the trace setting of an event. Tracing of the event is disabled by this option.

Tracing of a subsystem is disabled by this option.

To reset the trace subsystem, select the subsystem from the list. Selecting "ALL" resets tracing of all subsystems.


ELS Set Pin

Sets the pin parameter to the maximum number of traps that can be sent on a per-second basis. Internally, the pin is reset every tenth of a second. (One tenth of the maximum number of traps is sent every tenth of a second.)

For pin:

Valid values: 0 to 65535

Default value: 0

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


ELS Set Trace Default-Bytes-Per-Pkt

For default bytes per packet:

Valid values: 1 to 256

Default value: 100

To set the default bytes per packet, enter the number of bytes and then select the Submit button.


ELS Set Trace Disk-Shadowing

Turns disk shadowing on or off and sets the maximum trace file size. If disk shadowing is enabled, trace records are copied to the hard disk. Once a traced record is copied to the hard disk, it is no longer viewable through the console.

To turn on disk-shadowing, select ON.

To turn off disk-shadowing, select OFF.

To set the size of the disk-shadow, select MAX-FILE-SIZE.

    Default value: None

  2. Enter the filter base.
