C360 Features and Benefits
Stacking
●
You may create logical stacks of up to ten switches that you manage and configure as a
single switch.
●
Stacking is based on the Octaplane™ stacking system that provides eight Gbps stacking
bandwidth to all switches in the stack.
●
Each member of the stack is connected to the other members using a dedicated stacking
module and cables.
●
When the switches are stacked, the switches elect one switch as the master, while the
other switches act as slaves. The master switch acts as the stack management agent
reporting to the management system.
●
Management redundancy - if the master unit fails, the remaining switches elect a new
switch as the master, and the original stack configuration and IP address are maintained.
●
You can add, remove and replace switches in the stack without disrupting operation.
●
Auto-reconfiguration for replaced switch - the configuration of the units is distributed over
the stack. When you replace a unit, you do not need to reconfigure stack-level parameters
such as Spanning Tree, IP address and port redundancy.
Network Optimization
●
Autosensing of port speed and autonegotiation of duplex mode on all switch ports for
optimizing bandwidth.
●
IEEE 802.3x flow control on all Ethernet ports.
●
Auto MDI/MDI-X (cross-over cable) detection allows use of both straight and crossover
cables without the need to configure ports individually.
●
LAGs (Link Aggregate Group) provide enhanced fault tolerance and aggregated
bandwidth of up to 800 Mbps (on 10/100BASE-T ports) or 2 Gbps (on 1000BASE-X ports).
- Ideal for high-bandwidth connections to servers, routers and switches.
- Refer to LAG (Link Aggregate Group) on page 138 for further information.
●
IGMP (Internet Group Management Protocol) Snooping for limiting flooding of multicast
traffic.
