About SDLC Relay Configuration and Monitoring Commands
Enter SDLC Relay configuration commands at the SDLC Config> prompt. Changes made to the router's configuration do not take effect immediately. They only become part of the router's non-volatile configuration memory when it restarts.
Conversely, you enter SDLC Relay monitoring commands at the SDLC> prompt. These commands take effect immediately, but do not become part of router's non-volatile configuration memory. Thus, while monitoring commands allow you to make real-time changes to the router's configuration, these changes are temporary. The router's configuration memory overwrites them when the router restarts.
Monitoring consists of these actions:
Monitoring the protocols and network interfaces currently in use by the router.
Displaying Event Logging System (ELS) messages relating to router activities and performance.
Making real-time changes to the SDLC Relay configuration without permanently affecting the router's non-volatile configuration memory.
If the Config> prompt does not appear immediately, press Return again. Enter SDLC Relay configuration commands at the SDLC config> prompt. To access this prompt, enter protocol sdlc as shown:MOS Operator Control

Add [C]
Adds group numbers, local ports, and remote ports.
Syntax: add
add group
Group number: [1]? 1
Point to Point connection: (Yes of No)? Y
|
Group number
| The group number that you are designating for the port. |
|
Point to point
| Is the connection a point-to-point link, yes (Y) or no (N). |
local-port
Identifies the interface that you are using for the local port.
Example: add local-port
Group number: [1]?1
Interface number: [0]? 0
(P)rimary or (S)econdary:[S}? p
remote-port
Identifies the IP address of the port directly connected to the serial line on the remote router.
Example: add remote-port
Group number: [1]? 1
IP address of remote router:[0.0.0.0]? 128.185.121.97
(P)rimary or (S)econdary:[S]? s
Clear-Port-Statistics [M]
Resets the SDLC Relay statistics for all ports. The statistics include counters for packets forwarded and packets discarded.
Syntax: clear-port-statistics
clear-port-statistics
Clear all port statistics? (Yes or No): Y
delete group 1
delete local-port 0
delete remote-port
Group number: [1]? 1
(P)rimary or (S)econdary:[S}? S
|
Group number
| The group number for the remote port. |
|
Primary or Secondary
| Designates the port type, primary (P) or secondary (S). |
Disable [C] [M]
Suppresses forwarding for an entire relay group or a specific relay port.
When you use this command within the monitoring process, its effects are not stored in the router's non-volatile configuration memory.
Syntax: disable
disable group 1
disable port
Interface number: [0]? 0
(P)rimary or (S)econdary:[S]? s
|
Interface number
| The interface number of the port that you want to disable. |
|
Primary or Secondary
| Designates the port type, primary (P) or secondary (S). |
Enable [C] [M]
Enables data transfer for an entire group or a specific local interface port.
When you use this command within the monitoring process, its effects are not stored in the router's non-volatile configuration memory.
Syntax: enable
enable group 1
enable port
Interface number: [0]? 0
(P)rimary or (S)econdary:[S]? s
|
Interface number
| The interface number of the port that you want to enable. |
|
Primary or Secondary
| Designates the port type, primary (P) or secondary (S). |
List [C] [M]
Displays the configuration or status of a specific group or of all groups.
Syntax: list
list all

Exit [C] [M]
Exits the SDLC Relay configuration or monitoring process.
Syntax: exit
exit
