●
Dynamic VLAN assignment is supported through implementation of VLAN Membership Policy Server client
capability to provide flexibility in assigning ports to VLANs. Dynamic VLAN facilitates the fast assignment of
IP addresses.
Borderless Experience
Borderless network enables enterprise mobility and business-grade video services. The industry’s first unified
network (wired and wireless) location services enable tracking of mobile assets and the users of those assets for
both wired and wireless devices. The true borderless experience is enabled by the following feature sets in the Cisco
Catalyst 2960-S and 2960 Series Switches:
●
High availability and Layer 2 networking
●
Enhanced quality of service (QoS)
●
Location awareness and mobility
High Availability and Layer 2 Networking
The Cisco Catalyst 2960-S Series Switches provides Cisco FlexStack stacking and both the Cisco Catalyst 2960-S
and 2960 Series switches provide Layer 2 networking to enable resiliency and availability.
Other high-availability features include but are not limited to:
●
Cross-Stack EtherChannel provides the ability to configure Cisco EtherChannel technology across different
members of the Cisco FlexStack for high resiliency.
●
Flexlink provides link redundancy with convergence time less than 100 ms.
●
IEEE 802.1s/w Rapid Spanning Tree Protocol (RSTP) and Multiple Spanning Tree Protocol (MSTP)
provide rapid spanning-tree convergence independent of spanning-tree timers and also offer the benefit of
Layer 2 load balancing and distributed processing. Stacked units behave as a single spanning-tree node.
●
Per-VLAN Rapid Spanning Tree (PVRST+) allows rapid spanning-tree reconvergence on a per-VLAN
spanning-tree basis, without requiring the implementation of spanning-tree instances.
●
Switch-port autorecovery (Errdisable) automatically attempts to reactivate a link that is disabled because
of a network error.
Enhanced Quality of Service
The Cisco Catalyst 2960-S and 2960 Series Switches offers intelligent services that keep everything flowing
smoothly. Industry-leading mechanisms for marking, classification, and scheduling deliver superior performance for
data, voice, and video traffic, all at wire speed.
Following are some of the QoS features supported in the Cisco Catalyst 2960-S and 2960 Series Switches:
●
Cross-stack QoS allows QoS to be configured across the entire Cisco Catalyst 2960-S Flexstack.
●
802.1p class of service (CoS) and differentiated services code point (DSCP) field classification are
provided, using marking and reclassification on a per-packet basis by source and destination IP address,
MAC address, or Layer 4 TCP/UDP port number.
●
Cisco control-plane and data-plane QoS ACLs on all ports help ensure proper marking on a per-packet
basis.
●
Four egress queues per port help enable differentiated management of different traffic types across the
stack.
●
Shaped Round Robin (SRR) scheduling helps ensure differential prioritization of packet flows by intelligently
servicing the ingress queues and egress queues.
