Port Mode

 

Port LED Color

Meaning

 

 

 

 

STAT

 

Off

No link or port was administratively shut down.

(port status)

 

 

 

 

Green

Link present.

 

 

 

 

 

 

 

 

Blinking green

Activity. Interface is sending or receiving data.

 

 

 

 

 

 

Alternating

Link fault. Error frames can affect connectivity, and errors such as

 

 

green-amber

excessive collisions, cyclic redundancy check (CRC) errors, and

 

 

 

alignment and jabber errors are monitored for a link-fault

 

 

 

indication.

 

 

 

 

 

 

Amber

Port is blocked by Spanning Tree Protocol (STP) and is not

 

 

 

forwarding data.

 

 

 

After a port is reconfigured, the port LED can remain amber for up

 

 

 

to 30 seconds as STP searches the switch for possible loops.

 

 

 

 

 

 

Blinking amber

Port is blocked by STP and is sending and receiving packets.

 

 

 

 

DUPLX

 

Off

Port is operating in half duplex.

(duplex)

 

 

 

 

Green

Port is operating in full duplex.

 

 

 

 

 

 

SPEED

 

10/100 and 10/100/1000 ports

 

 

 

 

 

 

Off

Port is operating at 10 Mb/s.

 

 

 

 

 

 

Green

Port is operating at 100 Mb/s.

 

 

 

 

 

 

Blinking green

Port is operating at 1000 Mb/s.

 

 

 

 

 

 

SFP module ports

 

 

 

 

 

 

 

Off

Port is operating at 10 Mb/s.

 

 

 

 

 

 

Green

Port is operating at 100 Mb/s.

 

 

 

 

 

 

Blinking green

Port is operating at 1000 Mb/s.

 

 

 

 

 

 

SFP+ module ports

 

 

 

 

 

 

 

Off

Port is not operating.

 

 

 

 

 

 

Blinking green

Port is operating at 10 Gb/s.

 

 

 

 

 

 

Green

Port is operating at 1 Gb/s.

 

 

 

 

STACK

 

Off

No stack member has that member number.

(stack member)

 

 

 

 

Blinking green

Stack member number.

 

 

 

 

 

 

Green

Member numbers of other stack member switches.

 

 

 

 

If your switches are stacked and you press the Mode button on any switch, all the switches display the same selected mode. For example, if you press the mode button on the stack master to display SPEED, all the other stack members display SPEED.

Even if PoE mode is not selected, this LED still shows PoE problems if they are detected.

Cisco Systems 2960 series switches are a prominent solution in the networking landscape, known for their reliability, scalability, and feature-rich offerings. Ideal for small to medium-sized enterprises, these switches provide a robust foundation for network infrastructure, ensuring optimal performance and connectivity.

One of the standout features of the Cisco 2960 series is its Layer 2 switching capabilities. The switches support multiple VLANs (Virtual Local Area Networks), allowing network administrators to segment traffic efficiently and enhance security protocols. This is crucial in modern networks where managing traffic and isolating sensitive information is a priority.

The Cisco 2960 series also incorporates advanced Quality of Service (QoS) features, enabling the prioritization of critical applications and services. This functionality ensures that time-sensitive data, such as voice and video traffic, maintains a high quality of service even in congested networks. With support for IEEE 802.1p and DSCP marking, administrators can fine-tune their network performance to meet specific organizational needs.

Power over Ethernet (PoE) is another significant characteristic of the Cisco 2960 series. This feature allows switches to deliver electrical power alongside data over Ethernet cables to devices such as IP phones, wireless access points, and surveillance cameras. With PoE, organizations can reduce clutter from power cables and increase deployment flexibility for various devices.

In terms of security, the Cisco 2960 series is equipped with a range of integrated security features. The switch supports port security, 802.1X authentication, and Access Control Lists (ACLs), providing robust defenses against unauthorized access and potential network vulnerabilities. These security measures are essential for protecting sensitive data and ensuring compliance with industry regulations.

Moreover, the Cisco 2960 series offers enhanced network management capabilities with Cisco's Intelligent Network Services. This includes support for Simple Network Management Protocol (SNMP), Cisco Prime, and Embedded Event Manager (EEM), allowing for efficient monitoring, troubleshooting, and policy enforcement across the network.

Additionally, the Cisco 2960 switches provide various models and configurations, catering to different networking needs. Options include models with varying port densities, uplink configurations, and stacking capabilities, making it easy for organizations to choose solutions that align perfectly with their requirements.

In summary, the Cisco 2960 series is a versatile and essential component of modern networking environments. Its advanced features, including Layer 2 support, QoS, PoE, robust security, and diverse management tools, make it an excellent choice for organizations looking to build a strong and secure network infrastructure.
