Features
See the following sections for information about feature-related changes.
Access-level and access-strict
If you configure the access policy mode to deny, the system checks the mode and service, and if
they match the system denies the connection. With the access policy mode configured to deny, the
system does not check accesslevel or access-strict information. If you configure the access
policy mode to allow, the system continues to check the accesslevel and access-strict
information. For more information, see
Data plane security on page 119.
Autonegotiation
The 10 GigabitEthernet fiber-based I/O module ports can operate at either 1 Gigabit per second
(Gbps) or 10 Gbps, dependent upon the capabilities optical transceiver that you install.
This presents an ambiguity with respect to the autonegotiation settings of the port, while 1 Gigabit
Ethernet (GbE) ports require autonegotiation; autonegotiation is not defined and is non-existent for
10 GbE ports.
For a 10GbE fiber-based I/O module, you have the capability to swap back-and-forth between 1
GbE and 10 GbE operation by simply swapping transceivers. To help with this transition between 1
GbE and 10 GbE port operation, Avaya allows you to configure autonegotiation when you install a
10 GbE transceiver, even though autonegotiation is not defined for 10GbE.
You can do this in anticipation of a port changeover from 10 GbE to 1 GbE. In this manner, you
could essentially preconfigure a port in 1 GbE mode while the 10 GbE transceiver is still installed.
The port is ready to go upon the changeover to the 1 GbE transceiver.
In addition, you can use a saved configuration file with autonegotiation enabled to boot a system
with either 10 GbE or 1 GbE transceivers installed. If you install a 1 GbE transceiver, the system
