Run Scripts; Block Subsequent Mac Authentication; Fail Open Vlan Continuity Mode - Avaya 4000 Series Troubleshooting Instructions

Run scripts

According to Avaya best practices for converged solutions, you can use the scripts to configure
the parameters for an Avaya stackable Ethernet Switch. The scripts can be executed in a
default or verbose mode.
In the automated or non-verbose mode, the switch is configured using predetermined
parameter values. In the verbose mode, the script guides you to configure the parameters
where the values must be provided as inputs when the script is executed.
In this release, run scripts are available in non-verbose and verbose mode for IP Office, and
verbose mode for Link Layer Discovery Protocol (LLDP) and Auto Detect Auto Configuration
(ADAC).

Block subsequent MAC authentication

Prior to Release 5.7, in Multiple Host with Multiple Authentication (MHMA) mode, if a station
successfully authenticates, the switch places the port in the RADIUS-assigned VLAN that
corresponds to the login credentials of that station. If a second station properly authenticates
on that same port, the switch ignores the RADIUS-assigned VLAN and the user is placed in
the same VLAN as the first successfully authenticated station, creating a potential security risk.
This feature enhancement gives the administrator the option of either using the current
implementation or a separate option that blocks subsequent MAC authentications if the
RADIUS-assigned VLAN is different than the first authorized station VLAN.

Fail Open VLAN Continuity mode

The Fail Open VLAN Continuity mode feature introduces a new mode of operation for EAP/
NEAP clients when the RADIUS server(s) become unreachable.
