VCStack Benefits
Powerful Management
VCStack is very simple to congure with almost plug-and-play functionality for initial setup. This simplicity is maintained for network
administrators, as the stack appears as a single virtual chassis for ongoing management and monitoring of performance, which can be
done using the industry standard Command Line Interface (CLI), or an intuitive Graphical User Interface (GUI). The following features
make powerful functionality available to the network administrator and support staff to further enhance the VCStack solution.
Remote Login allows exible management of devices
Management of a VCStack is simplied for network
administrators, as the stack acts as a single virtual chassis.
Occasionally however, it can be desirable to login to a specic
member of the stack. For example to manage feature licences
per individual unit. Remote login facilitates this by allowing a
user on the master switch to log into the CLI of another stack
member. Conguration commands are still applied to all stack
members, but ‘show’ commands, and commands that access the
le system are executed locally. Consequently, the management
interface into the VCStack provides the best of both worlds –
the VCStack can be managed as a single unit, or as individual
units, depending on which is more convenient for the task at
hand.
Provisioning for pre-conguration of network devices
To add exibility to the management of a VCStack, provisioning
provides the ability to pre-congure (or congure ‘ofine’) the
switch ports of devices that are not currently physically present.
This allows a network administrator to congure the ports of
an additional VCStack member, or expansion module (XEM)
before it is actually hot-swapped in. On the physical addition of
the unit, the conguration is automatically applied, minimizing
network disruption. The power of provisioning is further
increased as a VCStack will retain interface conguration for a
device that is removed, facilitating effortless hot-swap of units if
required.
Conguration Synchronization automates le
management
The conguration le that is loaded when the stack starts is
called the startup-cong. If the startup-cong on the master
switch is updated, the new startup-cong is automatically
saved to ash memory on all stack members. Similarly, it is
automatically copied to any unit that subsequently joins the
stack. This ensures that no updates will be lost on master
failover or stack unit replacement.
Extensive Statistics support network management
To facilitate managing network resources effectively, network
administrators require as much information as possible about
trafc volume and resource use. Extensive statistics available
from a VCStack virtual chassis provide a wealth of information
about data throughput on a per-port, per-resource, or
trafc type basis. This ensures the network administrator is
fully informed and able to manage resources to best meet
application and user requirements.
Providing exceptionally high network availability and simplicity of
operation, backed up with powerful management options that
can be used as required, VCStack is truly the solution for today’s
enterprise networks.
