Configuring SNA 9-21
LLC2 Host Parameters
1
Except
ffffffffffff
. Must be in 802.5 (Token Ring) format, which may require "bit
swapping" when entering the address. (See the explanation of
Host MAC Address
.)
2
A host address can be configured for one Originated and one Terminated session, but no
more than one each.
3
Must be less than the value for
T1
to ensure that the remote link station will receive the
delayed acknowledgment before
T1
expires.
4
An asterisk wildcard can be used as a final digit. (The
?
wildcard is not valid.) If fewer
than 15 digits are entered, an asterisk must be the final character.
5
1st digit must be
4, 5, 6
, or
7
, and an asterisk wildcard can be used as a final digit. If fewer
than 8 actual digits (not including an asterisk) are specified, zeros will be added to total
8 actual digits. This value must not conflict with the Locally Administered MAC
Address, described on page 6-5.
6
Displayed only if
Session Type
is
Terminated
.
7
Although selecting this item toggles between SNA and LLC2,
Type
must be
LLC2
.
8
Each
Local Subscriber ID
must begin with all of the actual Routing Subscriber ID. A
Local
or
Remote Subscriber ID
can contain an asterisk as the final digit; if so, the
asterisk will not be a "universal" wildcard, but instead will include the range
000–511
,
or
00–99
if 13 digits precede the wildcard, or
0–9
if 14 digits precede the wildcard.
9
Maxdata
will be overridden by
Maxdata
in the SNA PU parameters, and
Ma xin
will be
overridden by
Tw
in the LLC2 parameters.
