Mlt/Dmlt/Lag Dynamic Vlan Changes; Network Time Protocol (Ntp); Ping Source Address; Secure File Transfer Protocol (Sftp) - Avaya 4550T-PWR+ Fundamentals

MLT/DMLT/LAG Dynamic VLAN changes

Enhancements have been made to 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.

Network Time Protocol (NTP)

The switch supports both Simple Network Time Protocol (SNTP) and Network Time Protocol
(NTP) for time synchronization. You can configure SNTP and/or NTP with both primary and
secondary server for SNTP and up to 10 servers for NTP, IPv4 and IPv6 for SNTP and only
IPv4 for NTP.

Ping Source Address

For more flexible testing and network setup diagnostics, Ping has been enhanced so that you
can specify the IPv4 source address of the outgoing ICMP request. The source address must
be one of the active Layer 3 interfaces and you cannot specify the VRRP virtual address as
the source address for Ping.

Secure File Transfer Protocol (SFTP)

For secure (SSH) software images Secure File Transfer supports download of Agent and
diagnostic files and ASCII configuration file download and upload. SFTP allows secure transfer
of a binary configuration file between a switch or stack and an SFTP server that uses SFTP
with SSH version 2. Enabled by default, and available through ACLI and EDM, SFTP interacts
with SSH Client.
