Alert String

Alert Description

 

 

First Time Install

Important installation information for your switch.

 

 

Too many undersized/

A device connected to this port is transmitting packets shorter than 64 bytes or longer than

giant packets

1518 bytes (longer than 1522 bytes if tagged), with valid CRCs (unlike runts, which have invalid

 

CRCs).

 

 

Excessive jabbering

A device connected to this port is incessantly transmitting packets (“jabbering”), detected as

 

oversized packets with CRC errors.

 

 

Excessive CRC/alignment

A high percentage of data errors has been detected on this port. Possible causes include:

errors

• Faulty cabling or invalid topology.

 

• Duplex mismatch (full-duplex configured on one end of the link, half-duplex configured on

 

the other)

 

• A malfunctioning NIC, NIC driver, or transceiver

 

 

Excessive late collisions

Late collisions (collisions detected after transmitting 64 bytes) have been detected on this

 

port. Possible causes include:

 

• An overextended LAN topology

 

• Duplex mismatch (full-duplex configured on one end of the link, half-duplex configured on

 

the other)

 

• A misconfigured or faulty device connected to the port

 

 

High collision or drop rate

A large number of collisions or packet drops have occurred on the port. Possible causes

 

include:

 

• A extremely high level of traffic on the port

 

• Duplex mismatch

 

• A misconfigured or malfunctioning NIC or transceiver on a device connected to this port

 

• A topology loop in the network

 

 

Excessive broadcasts

An extremely high percentage of broadcasts was received on this port. This degrades the

 

performance of all devices connected to the port. Possible causes include:

 

• A network topology loop—this is the usual cause

 

• A malfunctioning device, NIC, NIC driver, or software package

 

 

Network Loop

Network loop has been detected by the switch.

 

 

Loss of Link

Lost connection to one or multiple devices on the port.

 

 

Loss of stack member

The Commander has lost the connection to a stack member.

 

 

Security violation

A security violation has occurred.

One of the standout features of the SMC6624M is its Layer 2 and Layer 3 switching capabilities, enhancing the flexibility and efficiency of network management. The switch supports VLANs (Virtual Local Area Networks), which allow administrators to segment network traffic for improved security and performance. This capability is essential for organizations looking to optimize their network resources and apply policies that enhance security.

The SMC6624M also integrates advanced Quality of Service (QoS) features, enabling the prioritization of network traffic. This is particularly useful for applications such as VoIP and video conferencing, where maintaining low latency and jitter is crucial for ensuring a seamless user experience. Users can define traffic classes and manage bandwidth allocation, which helps in maintaining the quality of critical applications even during peak usage times.

In terms of connectivity and performance, the SMC6624M includes 4 Gigabit SFP ports, allowing for fiber optic connections to extend network reach and provide flexibility in deployment. The ability to take advantage of high-speed fiber connections means businesses can scale their networks as needed without significant infrastructure changes.

Management options for the SMC6624M are comprehensive. It supports SNMP (Simple Network Management Protocol) for monitoring and managing network performance effectively. Additionally, the switch can be configured using a web-based interface, command-line interface (CLI), or through SNMP, providing flexibility to network administrators with different preferences and expertise.

Furthermore, the SMC6624M is built with a fanless design, which ensures quiet operation and is energy efficient. Its compact form factor and sturdy build make it suitable for installation in various environments, including data centers and office settings.

Overall, the SMC Networks SMC6624M stands out for its combination of speed, flexibility, and management features, making it an excellent choice for businesses looking to enhance their network infrastructure.
