• Run the scripts on a default configuration, otherwise previous settings may conflict with
the script settings and errors may occur.
• Do not run other commands while a script is in progress, especially when the script is run
via SNMP (the EDM version), because this will slow down the execution and EDM may
time out while waiting for a response.
• When using CLI, the scripts show confirmation messages for the settings that are
made.
• If a setting cannot be made, the currently running script stops and an error message is
shown.
• The script also logs messages and sends traps to indicate whether it has been
successfully executed or an error was encountered. The final configuration can be verified
with the ”show running” command.
• Error messages examples:
-
% Error setting VLAN attributes
% Error setting Switch Management IP and network mask % Error configuring
802.1AB
% Error creating Voice VLAN
% Error setting uplink ports
% Error enabling IP Routing
Link-state tracking
Link-state tracking (LST) binds the link state of multiple interfaces. The Link-state tracking
feature identifies the upstream and downstream interfaces. The associations between these
two interfaces form link-state tracking group.
Follow the steps in Configuring Systems on Avaya Ethernet Routing Switch 4000 Series
NN47205-500.
Guidelines
Follow these guidelines when using Link-state tracking:
• The maximum number of upstream members is 8.
• The maximum number of downstream members is 384.
• Valid interfaces are ports and trunks (MLT / LAG).
• An interface can belong only to a single link-state tracking group.
• A trunk-member port cannot be added to a link-state tracking group by itself.
• Only enabled MLTs can be tracking group members.
• A trunk which is a tracking group member cannot be disabled.
• Ports with link aggregation enabled cannot be added to a tracking group.
• The user is prevented from enabling link aggregation on a tracking group member port.
