AML problems

Standard 1.0 Modular Option EC Installation and Maintenance Guide November 1999

Note: The ESDI/MSDL port must first be in the

Disabled state.

If the first attempt to enable the link fails, the ACMS program

keeps trying until setup is successful or you enter the DIS

ESDI or DIS AML n LYR2 command. Every time the link

setup fails, the system prints error messages.

ACMS is a background program and continues until the DIS

ESDI or DIS AML n LYR2 command is entered, even if the

overlay is aborted.

Note: To disable autorecovery of an MSDL card, use DIS

AML n AUTO.

CON ESDI n

EST AML n LYR2

Set up the Link Layer (LAPB protocol) for the AML

application on ESDI/MSDL port n, which is placed in the

connected state. This command is valid only if the ESDI/

MSDL port is enabled. To enable the AML, the ENL CMS or

ENL AML n LYR7 command must also be entered.

DIS ESDI n

DIS AML n LYR2

Disable ESDI/MSDL port number n. The link layer is

disconnected and the ESDI/MSDL will not respond to far-

end requests for link initialization. A warning message

appears if an attempt is made to disable the active AML, but

the link can be disabled if desired.

DIS CMS n

DIS AML n LYR7

Disable AML port number n. This command does not disable

the actual ESDI/MSDL port, but disables application layer

processing. A warning message appears when you attempt to

disable the active AML, but the command is accepted.

Note: Do not use this command while the port is performing

a self-test (SFLT) on the AML.
