OSI/DECnet V Configuration Commands

This section summarizes and then explains the OSI configuration commands. The OSI configuration commands enable you to create or modify an OSI configuration. Enter all the OSI configuration commands following the OSI Config> prompt. Defaults for any command and its parameters are enclosed in brackets immediately following the prompt.

The configuring commands manipulate the permanent OSI database (SRAM).

Add

Use the add command to configure area and prefix addresses, receive passwords, and address aliases.

Syntax:

add: alias
: area...
: filter...
: prefix-address
: receive-password
: routing-circuit...
: template...

alias

Adds an ASCII string that designates a particular area address or system ID. The ASCII string can be a-z, A-Z, 0--9, a few other characters including the hyphen ( - ), comma ( , ), and underscore ( _ ). Do not use escape characters.

The offset indicates the position, in semi-octets (nibbles), where the ASCII string begins within the address (aliases used for system IDs have an offset of 1). The string must be the same size or longer than the segment it is designating or you will receive an invalid segment length message. The maximum allowable alias is 20 bytes.
Note: When using an alias input, you must surround it with brackets. For example: l1_update 47[newname]99999000012341234.

Example:

add alias
Alias [ ]:
Segment [ ]:
Offset [1]:

Alias: The character string you want to use
Segment: The NSAP segment that the alias is replacing
Offset: The location of the alias (in 4-bit, semi-octets) within the NSAP. The offset is determined from the beginning (left) of the NSAP as it is displayed on the terminal.

area area-addr

Adds additional area addresses (18-byte maximum) that the node supports. An L1 node that supports other areas considers those synonymous areas. One area address is the area portion of the configured NET. If you try to add a duplicate area address, the router will display an error message.

Example:

add area 47000580999999000012341234

Note:

When adding synonymous areas to an L1 node, use the set globals command to configure the maximum number synonymous areas allowed for this node. All routers within an area must use the same maximum number of synonymous areas. Adjacencies can not be established if they are different.

filter filter-name routing-circuit-name calling-DTE call-UserData priority

Adds parameters upon which the router bases its acceptance of incoming X.25 calls on an routing circuit, either a static incoming or dynamically assigned (DA) circuit.

The filter-name is the name you give the filter. The routing-circuit-name is the name of the routing circuit with which the filter is associated.

The calling-DTE is the address of the calling router.

The local router checks the DTE address of an incoming call against a prioritized list of filters for all circuits. A higher filter priority in the list means that a connection to that filter's calling DTE address is made first. It is recommended that you assign a higher priority to filters for static circuits than for DA circuits. This can prevent an incoming static call from being assigned a DA circuit.

The call-UserData can have one of three values - osi, dec, or user:

For osi, the router automatically configures an ISO protocol discriminator for the call data and requires the call to be from an OSI node.
For dec, the router expects the incoming calls to be from a Digital Equipment Company router.
For user, you are prompted for an additional entry of up to 16 octets. Enter text to constrain the acceptance of incoming calls. The call-UserData field of the incoming call must match the specified text.

Example:

add filter
Filter Name [ ]:
Routing Circuit Name [ ]:
DTE Address [ ]:
Call UserData (OSI/DEC/USER)]:

If you select user, and additional prompt appears for you to enter user data, followed by a Priority prompt:

	(max 16 octets) [ ]?
	Priority (1-10) [5]?

prefix-address

Adds static routes to destinations outside the IS-IS domain. This parameter prompts you for different information depending on the type of subnet (X.25, LAN, or FRL) that was configured using the set subnet command.

Note:

If no Address Prefix is entered, the default prefix is assumed.

Example:

LAN Subnet:

add prefix-address
Interface Number [0]:
Address Prefix [ ]:
MAC Address [ ]:
Default Metric [20]:
Metric Type [Internal]:
State [ON]:

X.25 Subnet:

add prefix-address
Interface Number [0]:
Address Prefix [ ]:
Mapping Type[Manual]:
DTE Address[]:
Default Metric[20]:
Metric Type [Internal]:
State [ON]:

Frame Relay Subnet:

add prefix-address
Interface Number [0]:
Address Prefix [ ]:
DTE Address [ ]:
Default Metric [20]:
Metric Type [Internal]:
State [ON]:

Note: If the subnet does not exist, you will receive the error message Subnet does not exist - cannot define a reachable address.

Interface Number

Defines the interface over which the address is reached

Address Prefix

Defines the NSAP prefix (20 bytes maximum).

MAC Address

Defines the destination MAC address. You must specify this address if the interface corresponds to a LAN subnet. This prompt will only appear if the interface is connected to a LAN subnet.

Mapping Type

Defines how the destination physical address is determined, manual or X.121.

If manual, the protocol will prompt for the DTE address.

If X.121, the protocol will not prompt you for the DTE address. The DTE address in this instance is extracted from the NSAP.

DTE Address

Defines the destination DTE address. You must specify this address if the interface is X.25 and the mapping type is manual. This prompt only appears if the interface is configured for X.25 and the mapping type is manual.

Default Metric

Defines the cost of the address.

Metric Type

Defines whether the metric cost is used for external (E) routing or internal (I) routing.

State

When set to ON, this prefix-address is advertised to other L2 routers. When set to OFF, this is a non-functional prefix-address.

routing-circuit

Adds a communications channel for X.25 switched virtual circuits (SVCs) that the routing layer uses to send and receive data.

The routing circuit parameter is only applicable if you configure your router as a DEC-type router. You can specify on of these types of routing circuit:

static-in
static-out
dynamically-assigned

A static-in circuit handles incoming X.25 calls. A call filter (see add filter) specifies data the router uses to accept or reject incoming calls on the circuit. A static-out circuit initiates outgoing X.25 calls. The router uses a call template (see add template) to make outgoing calls. A dynamically-assigned circuit can have multiple SVCs running simultaneously. Unlike static circuits, the router uses a dynamically-assigned circuit only when there is traffic in or out of the router. It closes the dynamically-assigned circuit upon expiration of an idle timer.

The add routing-circuit command prompts you for values for its parameters.

Example:

add routing-circuit
Interface number  [0]?
Circuit Name  [ ]?
Circuit Type (STATIC/DA)  [STATIC]?
Circuit Direction (OUT/IN)  [OUT]?

If you select STATIC and OUT, the following additional prompts appear:

Recall Timer (0-65535)  [60]?
Max Call Attempts (0-255)  [10]?
Initial Min Timer (1-65535)  [55]?
Enable IS-IS  [YES]?
Level 2 only  [NO]?
External Domain  [NO]?
Default Metric  [20]?
ISIS Hello Timer [3]?
Enable DECnetV Link Initialization  [YES]?
Modify Receive Verifier  (YES/NO)  [NO]?
Transmit Verifier (YES/NO)  [NO]?
Explicit Receive Verification (TRUE/FALSE)  [TRUE]?

If you select STATIC and IN, the following additional prompts appear:

Initial Min Timer (1-65535)  [55]?
Enable IS-IS [YES]?
Level 2 only [NO]?
External Domain [NO]?
Default Metric [20]?
ISIS Hello Timer [3]?
Enable DECnetV Link Initialization [YES]?
Modify Receive Verifier (YES/NO) [NO]?
Modify Transmit Verifier (YES/NO) [NO]?
Explicit Receive Verification (TRUE/FALSE) [TRUE]?

If you select DA for the circuit type, the following additional prompts appear:

Recall Timer (0-65535) [60]?
Reserve Timer (1-65536) [600]?
Idle Timer (1-65536) [30]?
Max SVCs (1-65535) [1]?

Interface Number: Specifies the logical X.25 interface for this routing-circuit.
Circuit Name: Sets up the alphanumeric name of this routing-circuit record.
Circuit Type: Specifies whether this routing circuit is either a STATIC circuit or a DYNAMICALLY ALLOCATED circuit.
Circuit Direction: Specifies IN or OUT to determine whether the SVC of the static circuit will be established with an incoming call request or an outgoing call request. In both cases, the SVC is initially established upon operator action, but the circuit is not fully enabled until both ends of the circuit have initialized successfully.
Recall Timer: Defines the time in seconds that an out-static circuit or a DA circuit must wait before attempting a new call request. This is a result of the initial call request failing or a subsequent call having been cleared.
Max Call Attempts: If a call request fails, Max Call Attempts defines the maximum number of subsequent call requests that are attempted by the out-static circuit before no further attempts are made. At this point, a call failure is logged and operator intervention is required to activate the out-static circuit.
Initial Min Timer: Specifies the amount of time (in seconds) an out-static circuit waits for a link to be initialized (reception of either an ESH or an ISH) after the call request has been accepted. If the initial min timer expires before the link has been fully initialized, the SVC is cleared and an event generated that indicates initialization failure.
Enable IS-IS: Defines whether the IS-IS protocol is enabled on this routing-circuit. When set to ON, the IS-IS protocol is enabled; when set to OFF, the IS-IS protocol is not enabled.
Level2 Only: Specifies if this routing-circuit is used for Level2 routing only.
External Domain: Specifies whether the router transmits and receives messages to and from a domain outside its IS-IS routing domain.
Default Metric: Defines the cost of this address.
ISIS Hello Timer: Defines the time interval between transmission of ISIS hellos.
Enable DECnetV Link Initialization: Defines whether DEC-style link initialization for this circuit is enabled (YES) or not (NO).
Modify Receive Verifier: Specifies verification data to be checked against on receiving an XID when verifying by circuit.
Modify Transmit Verifier: Specifies verification data to be included in the XID.
Explicit Receive Verification: Defines whether verification is by circuit or by system. TRUE specifies verification by circuit, and FALSE specifies by system.
Reserve Timer: Defines the time after the idle timer expires during which the router still considers a remote node on a DA circuit as "active." The router can forward data on the DA circuit until the reserve timer expires.
Idle Timer: Defines the length of time a DA adjacency my be idle (no data transmission) before it is cleared.
Max SVCs: Defines the maximum number of SVC adjacencies supported by this DA circuit. If no call can be placed because the maximum SVC adjacencies has been reached, then an event "Exceed Max SVC adjacencies" is generated.

receive-password

Adds an ASCII character string (16 characters maximum) that authenticates all incoming packets. An incoming packet whose password matches one of the set of receive-passwords is processed through the IS; any incoming packets whose passwords do not match are dropped.

Example:

add receive-password

Note:

You get an error message if you use an invalid password type.

Password type [Domain]:
Password [ ]:
Reenter password:

Password type

Designates one of the two types of passwords, domain or area.

Domain passwords are used with L2 LSPs (Level 2, Link State Packets) and SNPs (Sequence Number PDU).

Area passwords are used with L1 LSPs and SNPs.

Password

Designates the character string that you are using for authentication. Maximum allowable string is 16 characters.

template template-name routing-circuit-name destination-DTE call-UserData

Creates a template by which the router makes outgoing calls on a static-out routing circuit. Templates for static-out circuits are analogous to filters for static-in circuits.

The template-name is the name you give the template. The routing-circuit-name is the name of the routing circuit with which the template is associated.

The destination-DTE is an address for the remote router of up to 14 digits.

The call-UserData must match the call data set up for a filter on the remote circuit. Call-UserData can have one of three values - osi, dec, or user:

For osi the router automatically configures an ISO protocol discriminator for the call data and requires the call to go to an OSI router.
For dec the user data identifies the outgoing calls as coming from a Digital Equipment Company router.
For user you are prompted for an additional entry of up to 16 octets. Enter text to match the user data of the appropriate filter on a remote router.

Example:

add template
	Template Name []?
	Routing Circuit Name []?
	DTE Address []?

Ping-1139

Causes the router to send an echo request to a destination and wait for a reply, as recommended in RFC 1139. RFC 1139 specifies this as an OSI function and not as a DECnet function. Ping-1139 supports short- and long-term echos. Short-term echos use regular CLNP data packets, which makes them transparent to intermediate systems that do not support RFC1139. Long-term echos use PING request/reply packets.

The default data length of the echo request packet is 16 bytes. You can set the data length up to 64 bytes.

Once you enter the ping-1139 command, echo requests are sent continually until you press any key. At that time, statistics are displayed showing the number of requests transmitted and the number of replies received.

Syntax:

ping-1139

Example:

ping-1139
Long-term/Short-term [LONG-TERM]?
Destination NSAP:  []? AA0003000A14
Data Length [16]?
 
PINGing AA0003000A14

Destination System: 0000-9310-04C9
Destination MAC Address: AA00-0400-1408
Interface: 0

Destination System: Indicates the system ID of the next hop IS. For a directly connected ES, this will be blank.
Destination MAC Address: Indicates the MAC address of the next hop IS or the directly-connected ES.
Interface: Indicates the interface that a packet would go out over to reach the next hop IS or the directly-connected ES.

Send (Echo Packet)

Use the send echo packet command to encode an echo request message in the CLNP packet to the specified destination nsap. During this command, the system does not interact with the OSI monitoring. To verify that the echo request was sent and that an echo reply was received, check the ELS (Event Logging System).
Note: You cannot send an echo packet to yourself. If you try, you will receive an CLNP.004 ELS message.

Syntax:

send

Example:

send
Destination NSAP: []?

Subnets
