Avaya C360 Overview
20 Installation and Configuration Guide Avaya C360 Multilayer Stackable Switches, version 4.5
●
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
on page 134 for further information.
●
IGMP (Internet Group Management Protocol) Snooping for limiting flooding of multicast
traffic.
Manageability
●
SNTP (Simple Network Time Protocol) or TIME protocol for providing a consistent
timestamp to all switches from an external source. Refer to
Protocols Parameter Configuration
●
In-band management access:
- C360 Device Manager with intuitive Web-based access. Refer to
on page 193 for further information.
- Up to five simultaneous Telnet connections for multiple CLI (Command Line
Interface)-based sessions over the network. Refer to
on page 65 for further information.
