RBP
Record boundary preservation is a Cisco protocol that works with messages traveling
between X.25 and TCP/IP protocols. RBP allows for packet preservation of X.25 data
when transport is over a TCP/IP network.
RBP is equivalent in functionality to AEP in that X.25 packet boundaries are
maintained with the addition of a configurable record boundary.
Optional Parameter
TL1
The Translation Language One module typically works with messages traveling
between X.25 and asynchronous protocols. However, it also works with all other
protocols. Some OSSs require that each TL1 command/response be fully contained
in one X.25 packet. By packetizing on the TL1 termination characters (“;<>”), the TL1
module ensures that each TL1 command/response is transmitted in one X.25 packet.
PKT -P0xD,0x3B Provides packetizing and sets the packetizing characters to
carriage return and semi-colon.
PKT -F10,127 Provides packetizing and filters out the characters for line
feed and delete.
PKT -U Provides packetizing but prevents breaks from being
propagated upstream.
PKT -I10 -P0x0D -D Provides packetizing on carriage returns for .10 seconds of
idle time and prevents breaks from being propagated
downstream.
PKT -S13,10 Provides packetizing and sets the sequence to carriage
return followed by a line feed.
RBP -M
d
Defines the maximum record size in bytes. RBP will split an incoming
X.25 data packet across multiple records so that no single record
exceeds this value. X.25 packets with this parameter set will be
combined as long as the resulting record does not exceed this value. If
this value is not set, each X.25 data packet will be converted into exactly
one record. Valid range for this parameter is 256 to 1500. The default is
no M-bit.
