x25SapCes
Module: CXX25-MIB
OID (symbolic): CXX25-MIB::x25SapCes
OID (numeric): 1.3.6.1.4.1.495.2.1.6.29.21.1.2
Node type: OBJECT-TYPE
Type: Ces
Access: read-only
Description: Identifies the CES (connection endpoint suffix) that is associated with this SAP (service access point). CES is used by X.25 over the ISDN D channel to support multiple data links on one physical (LAPD) link. The CES for each link must be unique and is normally set in the range 0 to 63.
When associated with a LAPD service at the Data Link layer, the CES is combined with the data link SAPI (sap identification index) to form the connection endpoint identifier (CEI). This uniquely identifies each data link connection. The Data Link layer maps the CES to a TEI (terminal endpoint identifier), and combines it with the SAPI to form the DLCI (data link connection identifier), which is used on the ISDN D-Channel.
In the case of X.25 LAPB, CES is not used and is set to 0.
When this object is not specified (upper SAPs), its value defaults to 0.
Range of Values: 0 - 63
Default Value: none

What is x25SapCes?
A read-only CES (connection endpoint suffix, 0-63) identifying the second half of a SAP's identification alongside x25SapNumber; it's meaningful on ISDN D-channel (LAPD) SAPs supporting multiple data-link connections, and is 0 for LAPB SAPs and upper SAPs. Admins use the SAP-number/CES pair together to uniquely address a table row when reading SAP configuration.
