Cisco Catalyst Micro Switches Data Sheet (2023)

The Cisco®Catalyst®Micro Switches are Cisco's purpose-built family of products for FTTx deployments, enabling customers to eliminate IDF, save valuable space, conserve energy, and reduce cabling costs.

Product overview

Fiber to the Desk, Office etc. (FTTx) is not a new concept. In this deployment scenario, the improved reach of fiber optic cabling over copper cabling allows access switches to be deployed right next to end devices, with uplinks directly connected to the main frame, eliminating the need for an intermediate frame at each floor. However, as access switches get closer to end-users, the requirements on operating noise and product dimensions become more stringent. Enter Cisco Catalyst Micro Switches, a family of small, fanless switches designed specifically for FTTx deployments. These switches offer flexible mounting options and open up a wide range of network design and connectivity options.

software and security

Layer 2 functions for ease of use

IPv6 host support.

Simple Network Management Protocol (SNMP)v3 for secure configuration, control and information retrieval through appropriate MIBs.

Link-Aggregation-Control-Protokoll (LACP)for creating Ethernet channeling with devices that are IEEE 802.3ad compliant.

Dynamic Host Configuration Protocol (DHCP)automatic configuration of multiple switches via a boot server.

Cisco VLAN-Trunking-Protokoll (VTP), which supports dynamic VLANs and dynamic trunk configuration across all switches.

EmbeddedRemote monitoring (RMON)software agent for enhanced traffic management, monitoring and analysis; four RMON groups (History, Statistics, Alarms and Events) are supported.

Link-Layer-Discovery-Protokoll (LLDP)andLLDP Media Endpoint Discovery (LLDP-MED)Extensions for easy identification of end devices.

Constrained Application Protocol (CoAP)-Unterstützung

The switchesacts as a CoAP proxy. CoAP isA lightweight protocol that enables sensors, HVAC and security systems to provide advanced space analytics.

Security and Threat Defense

802.1X, MACAuth, TACACS+, and RADIUS authentication capabilities for secure endpoint onboarding.

Private VLAN (PVLAN)-EdgeProtected port function to restrict communication between end devices.

Device security:Role-Based Securityto enable network segmentation and prevent unauthorized use; Helps prevent the entire attack surface and contain attacks with device profilingwithCisco Identity Services Engine (ISE).

power management

Go into hibernation and deep sleep mode

Switch sleep management can be initiated through Cisco EnergyWise®, as was traditionally done, or via CoAP. CoAP support in the Catalyst Micro Switches enables a sleep trigger. This support is provided for initiating hibernation with Real Time Clock (RTC) configuration. The system can wake up based on a wake-on-clock and mode button.

IEEE 802.3az oder Energy Efficient Ethernet (EEE)

Ports dynamically detect idle times between traffic spikes and quickly switch the interfaces to a low-power idle mode, reducing power consumption.

Energy efficiency of the system

The switches also improve the industry standard of the systemenergy efficiency. During sleep, the system reduces its power consumption by 65%, improving its energy efficiency.

Cisco Energiemanager

Integrated with Cisco Energy Management Suite for complete energy control and visibility.

power supply

Certified AC/DC adapter.
