Avaya C360 converged stackable switches
Issue 6 January 2008 165
Stacking
● Up to 10 switches can be stacked together.
● Features such as Spanning Tree, redundancy, VLANs, and SMON are common to the
stack.
● The Octaplane stacking system provides 8 Gbps stacking bandwidth to all switches in the
stack.
● C360 stacks continue to function even if one switch or link fails.
● Switches in the stack can be added, removed, and replaced without disrupting operation.
● An advanced election algorithm ensures optimal stack master selection.
Layer 2 features
● Auto-sensing simplifies configuration of LAN connections by automatically selecting the
port speed for devices — either 10Mb or 100Mb.
● Auto-negotiation simplifies configuration of LAN connections by automatically selecting the
port transmission mode for devices — either half- or full-duplex.
● Auto-MDIX automatically adjusts for straight-through or crossover cables on all 10/100-TX
ports.
● Traffic prioritization (802.1p) allows real-time traffic classification into 8 priority levels
mapped to 4 queues.
● There are four egress queues on all switch ports. The queues can be configured with the
WRR (Weighted Round Robin) or strict priority scheduling algorithm.
● The use of the IEEE 802.1Q tagging for VLANs and per-port VLAN is supported.
● Multiple VLANs per port allow access to shared resources by stations that belong to
different VLANs.
● The use of the IEEE 802.1w standard for Rapid Spanning Tree Protocol (RSTP) provides
rapid convergence of the spanning tree in case of link failure.
● The use of the IEEE 802.1x standard for port-based network security ensures that only
authorized clients get network access.
● Up to 20 redundant-port pairs are supported to increase link resiliency.
● Inter-module redundancy is supported with one pair in a stack. The switching time is
approximately 1 second.
● Link Aggregation Group (LAG) support of up to 7 trunks, with each trunk having up to 8 10/
100 links or 2 GB links, provides resiliency, load balancing, and bandwidth expansion.
● LAG redundancy is supported through resiliency between two LAG groups.
● Port mirroring of any switch port is supported.
