Chapter 1: New in this release

The following sections detail what is new in Avaya Ethernet Routing Switch 4000 Series Fundamentals
(NN47205-102) for release 5.6.

Features

For information about changes for this release that apply to features, see the following
sections.

Cisco CLI Phase 1

In Release 5.6 selected ACLI commands for ARP, Spanning Tree, and VLAN have been
modified to use Cisco CLI syntax. While the interface software remains backwards compatible,
and ASCII configuration files you created prior to Release 5.6 will function normally, from
Release 5.6 and up the new Cisco CLI command syntax will be used for the commands for
ARP, Spanning Tree, and VLAN.

Disable MAC Learning

You can use Disable MAC Learning on a port when you want to control the Layer 2 Forwarding
Database (FDB) entries to prevent MAC tables from filling unnecessarily. You use Disable MAC
Learning in combination with Static MAC FDB Entry.

Equal Cost Multi Path (ECMP)

Routers use Equal Cost Multi Path to load balance traffic on equal cost paths to the same
destination prefix and to assure faster convergence to other active paths in case of network
failure.
