Port Mode

Port LED Color

Meaning

 

 

 

LRE

Off

No LRE link present on the LRE port.

 

 

 

 

Green

LRE link present on the LRE port. Port LED turns green within

 

 

10 seconds after the LRE port detects a connection to a

 

 

Cisco 575 LRE CPE.

 

 

 

 

Amber

LRE port and WAN CPE port unable to establish the rate defined

 

 

by the assigned profile.The switch has detected a CPE, but has not

 

 

established an LRE link at the configured profile.

 

 

Note The LED can be amber for a short period of time while

 

 

an LRE link is being established. However, if the LED

 

 

remains amber, there is a problem with the link between

 

 

the switch and the CPE.

 

 

 

STAT

Off

No link.

(port status)

 

 

Solid green

Link is present between LRE port and a CPE WAN port and also

 

 

 

between the CPE Ethernet port and the remote Ethernet device.

 

 

 

 

Flashing green

Activity. Port is transmitting or receiving data.

 

 

 

 

Alternating

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

 

green-amber

excessive collisions, CRC errors, and alignment and jabber errors

 

 

are monitored for a link-fault indication.

 

 

 

 

Solid amber

Port is not forwarding. Port was disabled by management or an

 

 

address violation or was blocked by Spanning Tree Protocol (STP).

 

 

Note After a port is reconfigured, the port LED can remain

 

 

amber for up to 30 seconds as STP checks the switch for

 

 

possible loops.

 

 

 

DUPLX

Off

Port is operating in half duplex.

 

 

 

 

Green

Port is operating in full duplex.

 

 

 

SPEED

Off

Port is operating at 10 Mbps.

 

 

 

 

Green

Port is operating at 100 Mbps.

2900 Series XL specifications

Cisco Systems 2900 Series XL routers are integral components of the Cisco Integrated Services Router (ISR) portfolio, designed to support various networking needs for small to medium-sized enterprises. These routers provide an extensive set of features tailored for voice, video, data, and wireless services, making them a versatile choice for organizations looking to streamline their network infrastructure.

One of the standout features of the 2900 Series XL is its modularity. This router is equipped with multiple interface card slots that allow users to customize and scale their network based on current and future requirements. The modular design offers flexibility in integrating various WAN interfaces such as T1/E1, DSL, and Ethernet, enabling businesses to adapt to changing connectivity needs without requiring a complete hardware overhaul.

The 2900 Series XL also supports a wide range of advanced security features. With integrated security protocols, such as firewall capabilities, Intrusion Prevention Systems (IPS), and Virtual Private Network (VPN) support, these routers ensure that sensitive company data remains protected against potential threats. Furthermore, the routers come with Cisco’s Adaptive Security Algorithm, which helps to detect and mitigate real-time attacks.

Another significant characteristic of the Cisco 2900 Series XL is its support for unified communications. The routers have built-in voice capabilities, allowing them to function as a voice gateway. This facilitates features like VoIP (Voice over IP), video conferencing, and even multimedia communication. These tools enhance collaboration and connectivity among team members, contributing to a more productive work environment.

The 2900 Series XL routers also include Cisco's IOS Software, which provides a robust operating system with a rich set of features for routing, switching, and security functions. The software is continually updated to ensure the routers remain compatible with the latest technology and security standards, thereby extending their functionality and lifespan.

In terms of performance, the 2900 Series XL routers are designed for high throughput and low latency, making them suitable for bandwidth-intensive applications. Their architecture supports services such as advanced Quality of Service (QoS) and traffic shaping, ensuring that mission-critical applications receive the bandwidth priority they require.

Ultimately, Cisco's 2900 Series XL routers represent a reliable, flexible solution for organizations looking to enhance their networking capabilities. With their exceptional features, comprehensive security options, and support for diverse applications and services, they play a crucial role in the modern digital landscape.
