8371 Interface Configuration

Configuring and Monitoring MPOA

This chapter describes how to use the MPOA configuration and operating commands and includes the following sections:

"Accessing the MPOA Configuration Environment"
"MPC Configuration Commands"
"Accessing the MPOA Monitoring Environment"
"MPC Monitoring Commands"

Accessing the MPOA Configuration Environment

Use the following procedure to access the MPOA configuration process.

At the OPCON prompt, enter talk 6. (For more detail on this command, refer to The OPCON Process and Commands in the 8371 Interface Configuration and Software User's Guide.)
After you enter the talk 6 command, the CONFIG prompt (Config>) displays on the terminal. If the prompt does not appear when you first enter configuration, press Return again.
At the CONFIG prompt, enter the protocol mpoa command to get to the MPOA Config> prompt.

MPOA Configuration Commands

The MPOA main menu includes the following commands.

Table 76. MPOA Configuration Command Summary

Command Function
? (Help) Displays all the commands available for this command level or lists the options for specific commands (if available). See "Getting Help".
MPC Enters the MPC configuration environment. for the MPC instance defined over a specified ATM device. See "MPC Configuration Commands" for additional information.
Exit Returns you to the previous command level. See "Exiting a Lower Level Environment".

Command	Function
? (Help)	Displays all the commands available for this command level or lists the options for specific commands (if available). See "Getting Help".
MPC	Enters the MPC configuration environment. for the MPC instance defined over a specified ATM device. See "MPC Configuration Commands" for additional information.
Exit	Returns you to the previous command level. See "Exiting a Lower Level Environment".

MPC Configuration Commands

To access the MPC configuration process, enter mpc device# at the MPOA Config> prompt to access the MPC Config> prompt. If you do not enter the device#, you will be prompted to supply the ATM device number.

Enter the following commands at the MPC Config> prompt. These commands apply to the MPC instance defined over the ATM device number supplied when you entered the MPOA Config> mpc device# command.

Table 77. MPC Configuration Command Summary

Command Function
? (Help) Displays all the commands available for this command level or lists the options for specific commands (if available). See "Getting Help".
Add Adds an MPC instance with default parameter values.
List Lists the enabled/disabled status of the MPC instance.
Config Allows explicit configuration of MPC parameters.
Remove Removes a MPC configuration.
Exit Returns you to the previous command level. See "Exiting a Lower Level Environment".

Note: The MPOA client does not have to be explicitly configured in order to start functioning at startup. If no explicit configuration of the MPC has been done under talk 6, an MPOA client is automatically created in the enabled state with a default set of parameter values and begins MPOA operation including shortcut initiation. You should explicitly configure any non-default configuration parameters. To prevent the MPOA client function from automatically being activated, you should use the config command to access the MPC Configuration> prompt and then use the disable command to create an MPC instance with a status of disabled.

Command	Function
? (Help)	Displays all the commands available for this command level or lists the options for specific commands (if available). See "Getting Help".
Add	Adds an MPC instance with default parameter values.
List	Lists the enabled/disabled status of the MPC instance.
Config	Allows explicit configuration of MPC parameters.
Remove	Removes a MPC configuration.
Exit	Returns you to the previous command level. See "Exiting a Lower Level Environment".

Add

Use the add command to add a MPC instance with default parameters.

The add option requires that an ATM interface has been previously added.

The added MPC defaults to enabled.
Note: When an MPC is created, it is automatically associated with all LECs on the ATM device that have a bridge port configured on them. There is no explicit configuration to associate particular LECs to the MPC. Further, this association is formed during startup time and not during configuration. Thus, even if no bridge ports have been defined at the time the MPC is added and configured, the MPC will still be associated with all LECs that have a bridge port associated with them at startup time. You cannot dynamically disable association of the MPC with a particular LEC at runtime.

Syntax:

add: MPC

Remove

Use the remove command to remove a MPC configuration.

Syntax:

remove: MPC

List

Syntax:

enable

Disable

Use the disable command to disable an MPC instance.

This command can also be used to create an MPC instance with a status of disabled.
Note: An MPC instance will be automatically created at startup, even if no MPC has been explicitly added. Use the disable command to disable this MPC instance if you do not want to configure MPC.

Syntax:

disable

Set

Use the set command to explicitly configure MPC parameters.

Syntax:

set: frame-count
: frame-time
: initial-retry-time
: maximum-retry-time
: hold-down-time
: vcc-timeout
: accept-config-from-lecs
: fragmentation-mode
: esi
: selector
: pcr
: max-reserved-bandwidth
: shortcuts
: ip-protocol
: ipx-protocol

frame-count

Controls the rate of traffic required before the MPC will initiate a shortcut to a given protocol destination. The MPC will initiate a shortcut when at least this many frames are forwarded to the same protocol destination for a period of frame-time seconds.

Valid Values: 1 to 65535 frames

Default Value: 10

frame-time

Controls the rate of traffic required before the MPC will initiate a shortcut to a given protocol destination. The MPC will initiate a shortcut when at least frame-count frames are forwarded to the same protocol destination for a period of this number of seconds.

Valid Values: 1 to 60 seconds

Default Value: 1

initial-retry-time

Specifies the initial value of the retry timer when the MPC sends a request. If a corresponding reply is not received before the expiration of the retry timer, the request is retried if the retry timer is less than maximum-retry-time and the retry timer is then doubled. This process will repeat until a reply is received or until the retry timer >= maximum-retry-time.

Valid Values: 1 to 300 seconds

Default Value: 5

maximum-retry-time

Specifies the maximum value of the retry timer when the MPC sends a request. If a corresponding reply is not received before the expiration of the retry timer, the request is retried if the retry timer is less than this value and the retry timer is then doubled. This process will repeat until a reply is received or until the retry timer >= this value.

Valid Values: 10 to 300 seconds

Default Value: 40

hold-down-time

Specifies the minimum time to wait before re-initiating a failed resolution request.

Valid Values: 30 to 1200 seconds

Default Value: 160

vcc-timeout

Specifies the length of time after which either inactive control or inactive data connections will be cleared.

Valid Values: 1 to 10080 minutes

Default Value: 20

accept-config-from-lecs

Specifies whether configuration parameters received from the LECS will be accepted by the MPC.

Valid Values: yes or no

Default Value: yes

fragmentation-mode

Controls the manner that the ingress MPC handles IP packet fragmentation.

When this parameter is set to maximize-shortcut-usage, frames requiring fragmentation will be sent to the MPOA server, while smaller frames will be sent over the shortcut. A potential consequence of using maximize-shortcut-usage is that packets can get out of order.

When this parameter is set to maximize-inorder-usage, usage of a particular shortcut will be suspended for the hold-down-time if a frame requiring fragmentation is received, causing all frames for the destination to be sent to the MPOA server.

When this parameter is set to perform-fragmentation, IP frames requiring fragmentation are fragmented by the MPC and then sent over the shortcut. Both shortcut usage and inorder delivery are maximized.
Note: A single flow requiring fragmentation can impact the performance of all flows.

Valid Values: maximize-shortcut-usage, maximize-inorder-packet-delivery, or perform-fragmentation

Default Value: perform-fragmentation

esi

Specifies the ESI that is to be used as the ESI component of the MPC's ATM address. The MPC implementation uses a single ATM address for control as well as data VCCs, so this ATM address refers to both the control and data ATM addresses of the MPC.

Valid Values:

Burned-in
One of the set of enabled ESI definitions for the MPC ATM device

Default Value: Burned-in

selector

Specifies the selector value that is to be used in combination with the esi to create a value that is unique among all protocol components using the MPC ATM device.

Valid Values: any single valid octet value that has not already been used

Default Value: automatically created

pcr

Specifies the desired peak cell rate for connections established by the MPC over the associated ATM device.

All connections established by the MPC are best-effort connections.

Valid Values: 0 - line speed of the ATM device (integer Kbps)

Default Value: line speed of the ATM device

max-reserved-bandwidth

Specifies the maximum amount of reserved bandwidth acceptable on incoming calls received over the associated ATM device.

Valid Values: 0 - line speed of the ATM device (integer Kbps)

Default Value: 0

shortcuts

Specifies whether the MPC should establish shortcuts to LANE devices over the associated ATM device.

Valid Values: yes or no

Default Value: yes

If the value of this parameter is yes, you will be prompted for the following additional information:

Choice of source address for LANE shortcuts

Specifies what source MAC address is to be used in frames transmitted on LANE shortcut VCCs.

Valid Values:

The MAC address burned into the MPC's ATM device
A locally-administered MAC address
The MAC address provided in the MPOA resolution reply

Default Value: Burned-in MAC address

If you choose to provide a locally-administered MAC address, you will be prompted for the value to be used.

Valid Values: 12 hexadecimal digits in the range of X'400000000000' and X'7FFFFFFFFFFF'

Default Value: None

ip-protocol

Permits enabling or disabling of the MPOA protocol for IP traffic.

Valid Values: Yes or No

Default Value: Yes

ipx-protocol

Permits enabling or disabling of the MPOA protocol for IPX traffic.

Valid Values: Yes or No

Default Value: Yes

List

Use the list command to display configuration information about the existing MPC instance.

Syntax:

MPC Configure Monitoring Commands

Enter the following commands at the MPC-Configure> command prompt to dynamically change values of the MPC configuration parameters. The changes occur immediately and are temporary. The changes are applied to the running MPC instance and are not saved.

The commands for setting various configuration parameters are very similar to the corresponding commands using talk 6. Under talk 5, however, there are separate explicit commands for setting each parameter that can be dynamically configured, while under talk 6, all parameters are configured under the set command.
Note: Dynamic enabling/ disabling or creation/deletion of an MPOA client can also be done and the commands are under the MPC-BASE menu.

Two additional sets of configuration parameters available using the talk 5 config that do not have any talk 6 counterparts are the atm-packet-trace-filter and lan-packet-trace-filter commands. You can configure a mask for an ATM address or MAC address respectively. MPOA client packets are only traced if the remote ATM address of the VCC on which the packet is being sent or received or the destination MAC address of the packet if on a legacy LAN interface matches the configured mask.

The first example will result in only those MPOA client packets being traced on the ATM interface that are being sent/received over VCCs to a remote ATM address with the last two bytes being X'05'.

Example:

MPC CONFIGURE>atm
    ATM Address Pkt Trace Filter Value (40 hex digits)
     [0000000000000000000000000000000000000000]?
     0000000000000000000000000000000000000005
    ATM Address Pkt Trace Filter Mask (40 hex digits)
     [0000000000000000000000000000000000000000]?
     00000000000000000000000000000000000000ff

The following example will result in MPOA client packet tracing on the legacy LAN interfaces of only those packets for which the destination MAC address has a `40' as the first byte.

Example:

MPC CONFIGURE>lan
    LAN Pkt Trace Filter Value (12 hex digits)
     [000000000000]? 400000000000
    LAN Pkt Trace Filter Mask (12 hex digits)
     [000000000000]? ff0000000000

MPC Packet Tracing

MPOA client packet traces can be activated from the Event Logging System (ELS) which is an integral part of the device operating system. See the chapter entitled "Using the Event Logging System" and the chapter entitled "Configuring and Monitoring the Event Logging System" in 8371 Interface Configuration and Software User's Guide for additional information about ELS.
Note: Packet tracing for the MPOA server function is separate from that of the MPOA client function and is accessed as part of NHRP packet tracing.
For MPOA client packet tracing, use the MPOA ELS subsystem. MPOA client packet tracing supports the set trace decode on option. This option enables the MPOA output to be interpreted for viewing. For details on using the trace facility, see the description of the trace command in the chapter entitled "Configuring and Monitoring the Event Logging System" in 8371 Interface Configuration and Software User's Guide
MPOA client packets are identified by three different events under the MPOA ELS subsystem.

Event 61 traces all MPOA client control frames
Event 62 traces all MPOA client data frames
Event 63 traces all MPOA client frames on legacy LAN interfaces.

Sample Configuration

Example Configuration of an MPOA client

Notes:

(1) Enter the MPOA client configuration menus.

(2) First add an MPC.

(3) Confirm that an MPC has been added, then go into the config option for configuring this MPC.

(4) List the current configuration. Since we just added the MPC, all the configuration parameters have been set to the default values.

(4a) Some of the parameters displayed cannot be configured but are displayed simply for convenience. For instance the interface indicated refers to the ATM interface number on which the MPC is being configured.

(5) If we would like the MPC to be in disabled state on bringup, use the disable command. The MPC can be dynamically activated from the monitoring console (talk 5).

(6) Use the set command to configure various MPC parameters. Check the list of parameters which can be set using this command as shown below.

(7) The frame-count parameter can be configured as shown (setting it to 1 will effectively result in the MPC making shortcut attempts to every destination for which a packet is encountered, while setting it to a very large value will result in shortcuts only to destinations to which extremely heavy traffic is being sent).

(8) Configure the ESI portion of the ATM address of the MPC (the MPC uses a single ATM address as both its control and data ATM address). Two ESIs have already been administered under the ATM interface configuration menus.

(9) Configure the selector byte to be used along with the ESI as part of the MPC's ATM address.

(10) Configure parameters related to the use of LAN emulation shortcuts.

Note:

If LANE shortcuts are enabled, you are prompted for the choice of source MAC address to be used in the layer 2 header of LANE shortcut packets. Further, if option 2 (locally configured MAC address is chosen, then you are also prompted for the MAC address desired.

(11) Confirm the new configuration using the list command.
