Protocol

Trunking Options

 

 

LACP

Provides dynamic and static LACP trunking options.

(802.3ad)

Dynamic LACP — Use the switch-negotiated dynamic LACP trunk when:

– The port on the other end of the trunk link is configured for Active or Passive LACP.

– You want to achieve fault-tolerance for high-availability applications where you want a four-link trunk with one or more standby links available in case an active link goes down. (Both ends of the link must be dynamic LACP.)

Static LACP — Use the manually configured static LACP trunk when:

 

– The port on the other end of the trunk link is configured for a static LACP trunk

 

– You want to configure non-default spanning tree (STP) or IGMP parameters on an LACP trunk group.

 

– You want an LACP trunk group to operate in a VLAN other than the default VLAN and GVRP is disabled.

 

– You want to use a monitor port on the switch to monitor an LACP trunk.

 

See “Trunk Group Operation Using LACP” on page 6-23.

 

 

Trunk

Provides manually configured, static-only trunking to:

(non-

• Most switches and routing switches not running the 802.3ad LACP protocol.

protocol)

• Windows NT and Unix workstations and servers

 

Use the Trunk option when:

The device to which you want to create a trunk link is using a non-802.3ad trunking protocol

You are unsure which type of trunk to use, or the device to which you want to create a trunk link is using an unknown trunking protocol.

You want to use a monitor port on the switch to monitor traffic on a trunk.

 

See “Trunk Group Operation Using the “Trunk” Option” on page 6-26.

 

 

FEC

Provides static trunking to forwarding devices that also support FEC (Fast

 

EtherChannel®), such as some Cisco® switches and routers, and some Unix and Windows NT servers.

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.
