1  –  sap 

    set [node node-id] llc2 sap simple-name ...

    Modifies the attributes for an llc2 service access point entity,
    which allows links to be multiplexed over its associated port.
    The modifiable attributes and their data types [in brackets] are:

    lan station [local-entity-name]
    local lsap address [octet]

    Select link for information on setting the attributes of an
    llc2 sap link subentity.

1.1  –  lan_station 

    Default: No entity name     Value: Local entity name

    Specifies the name of the LAN station entity used by the SAP. You
    must specify a value for this attribute before you enable the SAP.

1.2  –  local_lsap_address 

    Default: 7E            Value: 00-FE

    Specifies the address of the local link service access point
    (LSAP) to be used. The lowest significant bit of this value must
    be clear; the address specified must be an individual address.

1.3  –  link 

    set [node node-id] llc2 sap simple-name link simple-name ...

    Modifies the attributes for an llc2 sap link entity, which
    represents one of the links that operates over a particular SAP.
    The modifiable attributes and their data types [in brackets] are:

    acknowledge timer [milliseconds]
    busy timer [milliseconds]
    holdback timer [milliseconds]
    local receive window size [integer]
    maximum data size [octets]
    poll timer [milliseconds]
    reject timer [milliseconds]
    remote lsap address [hex-number]
    remote mac address [lan-address]
    retry maximum [integer]

1.3.1  –  acknowledge_timer 

    Default: 1000          Value: 1-60000

    Specifies the time, in milliseconds, the link waits for an
    acknowledgment before initiating recovery action.

    The granularity of this timer is 10 milliseconds. Values that are
    not multiples of 10 are rounded up.

1.3.2  –  busy_timer 

    Default: 10000         Value: 1-60000

    Specifies the time, in milliseconds, the link waits for indication
    of the clearance of a busy condition at the remote station.

    The granularity of this timer is 10 milliseconds. Values that are
    not multiples of 10 are rounded up.

1.3.3  –  holdback_timer 

    Default: 500           Value: 0-60000

    Specifies the delay, in milliseconds, before an acknowledgment
    must be sent. The granularity of this timer is 10 milliseconds.
    Values that are not multiples of 10 are rounded down.

1.3.4  –  local_receive_window_size 

    Default: 127           Value: 1-127

    Specifies the window size used by the link for receiving frames.

1.3.5  –  maximum_data_size 

    Default: 1027          Value: 1-65531

    Specifies the largest frame size, in octets, the link can use to
    send or receive data. This value does not include the size of the
    frame header.

1.3.6  –  poll_timer 

    Default: 1000          Value: 1-60000

    Specifies the time, in milliseconds, the link waits for a response
    with the F bit set.

    The granularity of this timer is 10 milliseconds. Values that are
    not multiples of 10 are rounded up.

1.3.7  –  reject_timer 

    Default: 3000          Value: 1-60000

    Specifies the time, in milliseconds, the link waits for a reply to
    a REJ (reject) frame.

    The granularity of this timer is 10 milliseconds. Values that are
    not multiples of 10 are rounded up.

1.3.8  –  remote_lsap_address 

    Default: 7E            Value: Hex-number

    Specifies the address of the destination LSAP (local service
    access point) to be used by the link. The lowest significant
    bit must be clear; the specified address must be an individual
    address.

1.3.9  –  remote_mac_address 

    Default: 00-00-00-00-00-00      Value: LAN-address

    Specifies the destination MAC address to be used by the link.

1.3.10  –  retry_maximum 

    Default: 10            Value: 1-255

    Specifies the maximum number of times the link retransmits a frame
    before assuming a fatal error and taking more drastic recovery
    action.
