The G-24LC model provides:
- Twenty-10/100/1000Base-T ports for desktop connectivity.
- Four dual-purpose uplink ports, each having one 10/100/1000 Ethernet port and one Small Form-Factor Pluggable (SFP) Gigabit Ethernet port, with one active at a time.
Please note: SFP connectivity requires an adapter such as the GLC-FE-100FX transceiver.
The LAN Base feature set includes a rich Layer 2+ suite of intelligent
services, including advanced quality of service (QoS), granular rate
limiting, and access control lists (ACLs), and multicast services.
Security is delivered through a wide range of authentication methods, data encryption technologies, and Network Admission Control (NAC) based on users, ports, and MAC addresses.
There are two options for switch management: an embedded GUI device manager for all operating systems and the Windows-based Cisco Network Assistant available at no cost from the Cisco Web site.
Addition management is available through Cisco Works SNMP network-management software. CiscoWorks for Switched Internetworks provides end-to-end device, VLAN, traffic, and policy management. The Web-based CiscoWorks Resource Manager Essentials enables automated inventory collection, software deployment, easy tracking of network changes, views into device availability, and quick isolation of error conditions.

- Operating altitude: Up to 10,000 feet (3000m)
- Storage altitude: Up to 15,000 feet (4500m)
- Enhancements to the standard Spanning Tree Protocol, such as Per-VLAN Spanning Tree Plus (PVST+), UplinkFast, and PortFast, help to maximize network uptime.
- Multilayer QoS features help ensure that network traffic is classified and prioritized, and that congestion is avoided in the best possible manner.
- Each dual-purpose uplink port allows connection either through copper Ethernet or fiber-optic cables (fiber-optic requires an SPF adapter). manner.
- Express Setup simplifies initial configuration of a switch through a Web browser.
- ACLs can be used to restrict access to sensitive portions of the network by denying packets based on source and destination MAC addresses, IP addresses, or TCP/User Datagram Protocol (UDP) ports.
- ACL lookups are done in hardware, so forwarding performance is not compromised when implementing ACL-based security.
