Guidelines for Creating Trunks

LINK AGGREGATION COMMANDS

General Guidelines –

•Finish configuring port trunks before you connect the corresponding network cables between switches to avoid creating a loop.

•A trunk can have up to eight ports.

•The ports at both ends of a connection must be configured as trunk ports.

•All ports in a trunk must be configured in an identical manner, including communication mode (i.e., speed, duplex mode and flow control), VLAN assignments, and CoS settings.

•Any of the Gigabit ports on the front panel can be trunked together, including ports of different media types.

•All the ports in a trunk have to be treated as a whole when moved from/to, added or deleted from a VLAN via the specified port-channel.

•STP, VLAN, and IGMP settings can only be made for the entire trunk via the specified port-channel.

Dynamically Creating a Port Channel –

Ports assigned to a common port channel must meet the following criteria:

•Ports must have the same LACP system priority.

•Ports must have the same port admin key (Ethernet Interface).

•If the port channel admin key (lacp admin key - Port Channel) is not set when a channel group is formed (i.e., it has the null value of 0), this key is set to the same value as the port admin key (lacp admin key - Ethernet Interface) used by the interfaces that joined the group.

•However, if the port channel admin key is set, then the port admin key must be set to the same value for a port to be allowed to join a channel group.

•If a link goes down, LACP port priority is used to select the backup link.

SMC6752AL2 specifications

The SMC Networks SMC6752AL2 is a robust and versatile gigabit Ethernet switch designed to cater to the demands of medium to large enterprise networks. This switch delivers an impressive combination of performance, flexibility, and manageability, making it an ideal solution for businesses seeking to enhance their network infrastructure.

One of the standout features of the SMC6752AL2 is its 48 Gigabit Ethernet ports, allowing for high-speed network connections to a variety of devices such as servers, workstations, and other networked equipment. Additionally, the switch includes 4 SFP (Small Form-factor Pluggable) slots that provide options for connecting to other networking devices via fiber optics, enhancing the versatility of the network configuration.

The SMC6752AL2 supports advanced Layer 2 switching capabilities, which are crucial for efficient data handling and traffic management. With features such as VLAN (Virtual Local Area Network) support, the switch can segment network traffic to improve performance and security while effectively managing broadcast domains. It supports 802.1Q VLAN tagging, allowing for better network segmentation and isolation of different types of traffic.

Moreover, the switch is equipped with Quality of Service (QoS) features to prioritize critical data transmissions. This is essential for applications requiring real-time data flow, such as VoIP (Voice over Internet Protocol) and video conferencing. The SMC6752AL2's QoS capabilities enable users to classify and prioritize traffic, ensuring a smooth and seamless experience for bandwidth-intensive applications.

The SMC6752AL2 also includes features such as port mirroring and link aggregation, enhancing the monitoring and management capabilities of the network. Port mirroring allows administrators to duplicate traffic from one port to another for analysis and troubleshooting, while link aggregation enables combining multiple connections for increased bandwidth and redundancy.

In terms of security, the switch supports802.1X port-based authentication, providing a layer of network access control that ensures only authorized users can connect. This feature, combined with the ability to create access control lists (ACLs), helps to safeguard the network against unauthorized access and other potential threats.

Overall, the SMC Networks SMC6752AL2 is a feature-rich Ethernet switch that offers reliable performance and advanced capabilities for managing enterprise networks. Its combination of port density, layer 2 switching features, QoS functionalities, and enhanced security makes it an excellent choice for organizations looking to expand or upgrade their networking solutions. With the SMC6752AL2, businesses can maintain high-performance connectivity and effective network management tailored to their specific operational needs.
