●
Multilevel security on console access prevents unauthorized users from altering the switch
configuration.
●
Bridge protocol data unit (BPDU) Guard shuts down Spanning Tree PortFast-enabled interfaces when
BPDUs are received to avoid accidental topology loops.
●
Spanning Tree Root Guard (STRG) prevents edge devices not in the network administrator’s control from
becoming Spanning Tree Protocol root nodes.
●
IGMP filtering provides multicast authentication by filtering out nonsubscribers and limits the number of
concurrent multicast streams available per port.
●
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. 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 3750-X and 3560-X Series Switches:
●
High availability
●
High-performance IP routing
●
Superior QoS
●
Location awareness and mobility
High Availability
The Cisco Catalyst 3750-X Series increases availability for stackable switches. Each switch can operate both as
master controller and as forwarding processor. Each switch in the stack can serve as a master, creating a 1:N
availability scheme for network control. In the unlikely event of a single unit failure, all other units continue to
forward traffic and maintain operation.
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 stack 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 offers 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.
●
Cisco Hot Standby Router Protocol (HSRP) is supported to create redundant, failsafe routing topologies.
●
Switch-port autorecovery (Errdisable) automatically attempts to reactivate a link that is disabled because of
a network error.
