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 Addr ess .)
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 Maxin will be
overridden by Tw in the LLC2 parameters.
