8 Release Note
Software Release 2.6.4
C613-10404-00 REV A
SNMPv3
SNMPv3 provides enhanced security management features whilst maintaining
compatibility with earlier versions SNMPv1 and SNMPv2. The basic additional
features of version 3 are:
■ Message Authentication:
■ Hashing and time stamping is employed to ensure that messages are
received from valid sources.
■ Message Confidentiality
■ Encryption can be applied to messages to ensure content privacy.
■ Compatibility with previous versions SNMPv1 and SNMPv2
For more information, see the SNMP chapter in the Software Reference.
Stacking
Stacking affords the following advantages when managing a group of
switches:
■ Because stack members are connected by open standard Ethernet or uplink
switch ports, the switches can be at the same physical location or across
geographical areas.
■ Management interfaces are conserved because each stack is managed from
a single IP address or terminal connection.
■ Because a stack has one configuration file that is simple to maintain for all
member switches, it efficiently manages individual switches. Stacks are
easy to reconfigure in tune with changing network needs.
■ Stacks offer an alternative to managing a group of switches by using a CLI
or GUI on each switch, which is often tedious and time-consuming.
What is Stacking?
Stacking is a way to synchronise information across multiple switches and
manage them as one logical device. Stacking uses a proprietary protocol to
manage a group of separate switches as one.
When several switches perform similar functions, you can manage them as
one. For ease and simplicity, a stack can be managed from any stack member.
Topologies
A stack consists of a maximum of nine switches connected by switch ports in
the same Stacking VLAN. Stack members must be on the same LAN; however,
they can be in different physical locations. No extra hardware is required
because stack members use open standards interfaces. This allows flexible
topologies; typical ones are ring and star.
