Sdlc Max-Pdu - HP MSR series Command Reference Manual

Usage guidelines
This command specifies the MAC address of the peer end for an SDLC virtual circuit so as to provide the
destination MAC address for SDLC-to-LLC2 frame conversion. In DLSw configuration, a peer should be
configured for each SDLC address. The MAC address of the peer should be the MAC address of the
remote SNA device (physical address in the Ethernet or Token Ring format), or the compound MAC
address obtained from SDLC virtual MAC address of the peer end and the SDLC address of the local
end.
In this configuration, pay attention to the difference in bit order between a token ring address and an
Ethernet address:
If the remote SDLC peer to be configured uses a token ring address, use its token ring address
•
directly;
If the remote SDLC peer uses an Ethernet address, reverse the bit order of the Ethernet address: for
•
example, convert 000f-e203-a548 to 0007-3fc0-a512. HP recommends that you use the dlsw
reverse command to avoid errors that might be introduced in manual conversion.
Examples
# Configure an SDLC peer on Serial 2/0.

sdlc max-pdu

Use sdlc max-pdu to configure the maximum SDLC PDU size, the maximum size of a frame that the router
can send, not including the frame check sequence (FCS), start flag and ending flag fields.
Use undo sdlc max-pdu to restore the default.
Syntax
sdlc max-pdu number
undo sdlc max-pdu
Default
The maximum SDLC PDU size is 265 bytes.
Views
Synchronous serial interface view
Default command level
2: System level
Parameters
number: Maximum SDLC PDU size in bytes, in the range of 1 to 17,600.
Usage guidelines
The maximum PDU size of some PU2.0 devices is 265 bytes, and that of an IBM AS/400 is 521 bytes.
Typically, this maximum PDU size should be configured to be the same as on the peer SDLC device.
Examples
# Set the maximum SDLC PDU size to 521 on Serial 2/0.
