snmp Simple Network Management Protocol: Allows you to manage
the switch from a network management station, including
support for security features, event reporting, flow sampling,
and standard MIBs.
Management and Configuration Guide
sntp Simple Network Time Protocol: Synchronizes and ensures a
uniform time among interoperating devices.

ssh 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.
SSH messages also include events from the Secure File
Transfer Protocol (SFTP) feature. SFTP provides a secure
alternative to TFTP for transferring sensitive information, such
as switch configuration files, to and from the switch in an SSH
session.

Access Security Guide
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):
Ensures that only one active path exists between any two
nodes in a group of VLANs in the network. MSTP operation is
designed to avoid loops and broadcast storms of duplicate
messages that can bring down the network.
Advanced Traffic Management Guide
system Switch management, including system configuration, switch
bootup, activation of boot ROM image, memory buffers, traffic
and security filters.
System messages also include events from Management
interfaces (menu, CLI, web browser, ProCurve Manager) used
to reconfigure the switch and monitor switch status and
performance.
