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.
o poll timer
Default: 1000 Value: 1-60000
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.
o reject timer
Default: 3000 Value: 1-60000
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.
o remote lsap address
Default: 7E Value: Hex-number
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.
o remote mac address
Default: 00-00-00-00-00-00 Value: LAN-address
Specifies the destination MAC address to be used by the link.
The lowest significant bit of the first octet must be clear;
that is, the address must be an individual address.
o retry maximum
Default: 10 Value: 1-255
Maximum number of times the link retransmits a frame
before assuming a fatal error and taking more drastic recovery
action.
