Secure Shell version 2 (SSHv2): Provides remote access to
management functions on a switch via encrypted paths
between the switch and management station clients capable
of SSH operation.

stack

Stack management: Uses a single IP address and standard
network cabling to manage a group (up to 16) of switches in
the same IP subnet (broadcast domain), resulting in a reduced
number of IP addresses and simplified management of small
workgroups for scaling your network to handle increased
bandwidth demand.

Advanced Traffic Management Guide

stp Multiple-instance

spanning

tree protocol/MSTP (802.1s):
