Chapter 38. Configuring and Monitoring SDLC Interfaces
This chapter describes the SDLC configuration and operational commands.
This chapter includes the following sections:
v “Accessing the SDLC Configuration Environment”
v “SDLC Configuration Commands” on page 540
v “Accessing the SDLC Monitoring Environment” on page 549
v “SDLC Monitoring Commands” on page 550
v “SDLC Interfaces and the GWCON Interface Command” on page 557
v “Statistics Displayed for SDLC Interfaces” on page 557
Changes made at the configuration command console (SDLC CONFIG>) become part
of the SRAM configuration when you restart the router.
Conversely, SDLC monitoring commands entered within the SDLC monitoring
process take effect immediately. However, changes made with monitoring
commands do not become part of the router’s static configuration. When the router
is restarted, the effects of the monitoring commands are overwritten by the router’s
static configuration. Monitoring consists of these actions:
v Monitoring the protocols and network interfaces that are currently in use by the
router
v Making real-time changes to the SDLC configuration without permanently
affecting the SRAM configuration
v Displaying ELS (Event Logging System) messages relating to router activities
and performance
Accessing the SDLC Configuration Environment
Use the CONFIG process to change the configuration of the router. The new
configuration takes effect when the router is restarted.
To enter the configuration process:
1. Enter talk 6 (or t6), at the OPCON (*) prompt. This brings you to the CONFIG>
prompt as shown in the following example:
MOS Operator Control
* talk 6
CONFIG>
If the CONFIG> prompt does not appear immediately, press the Enter key again.
All SDLC configuration commands are entered at the SDLC config> prompt.
2. At the Config> prompt, enter the set data-link sdlc command. When prompted,
enter the name of the interface to associate with the SDLC device.
Config>set data-link sdlc
Interface number [0]? 2
Config>
3. Next, enter the network command, plus the number of an SDLC interface that
you entered earlier.
Config>network 2
SDLC 2 Config>
