3Com 3031 Command Reference Manual page 527

Example
Configure the SDLC timeout retransmission times as 30.
[3Com-Serial1/0/0] sdlc max-transmission 30
sdlc modulo Syntax
sdlc modulo n
undo sdlc modulo
View
Synchronous serial interface view
Parameter
Description
Using the sdlc modulo command, you can configure the modulus of the SDLC.
Using the undo sdlc modulo command, you can restore the default modulus of
the SDLC.
By default, the SDLC modulus is 8.
SDLC, like X25, adopts modulus mode to number information packets, and the
modulus of SDLC is 8 or 128. Generally modulus 8 is selected.
Example
Restore the default modulus of the SDLC.
[3Com-Serial1/0/0] undo sdlc modulo
sdlc sap-map local Syntax
sdlc sap-map local lsap sdlc-addr
undo sdlc sap-map local lsap sdlc-addr
View
Synchronous serial interface view
Parameter
Description
Using the sdlc sap-map local command, you can configure the SAP address on
transforming the SDLC into the LLC2. Using the undo sdlc sap-map local
command, you can restore the default value of the LLC2 SAP address.
By default, lsap is 04.
When the SDLC packet is translated into the LLC2 packet, the SAP address is
needed besides the MAC address.
Generally speaking, the SAP address of the SNA protocol is 0x04 or 0x08 or 0x0C.
n: SDLC modulus, with available value of 8 or 128.
lsap: The virtual SAP address set by the device connected with the local
interface.
sdlc-addr: The SDLC address.
