■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 00e0.fc03.a548 to 0007.3fc0.5a12. You are recommended to use the dlsw reverse command to avoid errors that may be introduced in manual conversion.

Example # Configure an SDLC peer on Serial 2/0.

Parameter number: Maximum SDLC PDU size in bytes, in the range of 1 to 17,600.

Description Use the sdlc max-pducommand to configure the maximum SDLC PDU size, namely the maximum size in bytes of a frame that the router can send, not including the frame check sequence (FCS), start flag and ending flag fields.

Use the undo sdlc max-pducommand to restore the default setting.

By default, the maximum SDLC PDU size is 265 bytes.

The maximum PDU size of some PU2.0 devices is 265 bytes, while that of an IBM AS/400 is 521 bytes. Typically, this maximum PDU size should be configured be the same as on the peer SDLC device.

Example # Set the maximum SDLC PDU size to 521 on Serial 2/0.

<Sysname> system-view

[Sysname] interface serial 2/0

[Sysname-Serial2/0] sdlc max-pdu 521
