MLT/DMLT/LAG Dynamic VLAN Changes
Enhancements are made to the Link Aggregation Groups (LAG) that provide consistent operation of
Multi-Link Trunk (MLT), Distributed Multi-Link Trunk (DMLT), and LAGs so that you can make VLAN
changes on trunks without disabling the trunk first.
For more information on MLT/DMLT/LAG Dynamic VLAN Changes, see Configuring Layer 2 on
Avaya Ethernet Routing Switch 3500 Series, NN47203-500.
Static STP Multicast Destination Configuration
Static STP Multicast Destination Configuration feature allows to modify the STP Default Spanning
Tree Group (essentially, the 802.1d STP) destination multicast MAC address to a custom MAC
address.
For more information about Static STP Multicast Destination Configuration, see Configuring Layer 2
on Avaya Ethernet Routing Switch 3500 Series, NN47203-500.
Syslog enhancements
Remote logging allows to send system messages to a remote syslog. With the syslog enhancement
feature, the messages are sent in User Datagram Protocol (UDP) packet to a remote Syslog host
using port 514.

Series, NN47203-501.
