ACCESS CONTROL LISTS

Command Usage

The following restrictions apply to ACLs:

Each ACL can have up to 32 rules.

The maximum number of ACLs is 88.

However, due to resource restrictions, the average number of rules bound to the ports should not exceed 20.

This switch supports ACLs for ingress filtering only. However, you can only bind one IP ACL to any port and one MAC ACL globally for ingress filtering. In other words, only two ACLs can be bound to an interface - Ingress IP ACL and Ingress MAC ACL.

The order in which active ACLs are checked is as follows:

1.User-defined rules in the Ingress MAC ACL for ingress ports.

2.User-defined rules in the Ingress IP ACL for ingress ports.

3.Explicit default rule (permit any any) in the ingress IP ACL for ingress ports.

4.Explicit default rule (permit any any) in the ingress MAC ACL for ingress ports.

5.If no explicit rule is matched, the implicit default is permit all.

Setting the ACL Name and Type

Use the ACL Configuration page to designate the name and type of an ACL.

Command Attributes

Name – Name of the ACL. (Maximum length: 16 characters)

Type – There are three filtering modes:

-Standard: IP ACL mode that filters packets based on the source IP address.

-Extended: IP ACL mode that filters packets based on source or destination IP address, as well as protocol type and protocol port number. If the “TCP” protocol is specified, then you can also filter packets based on the TCP control code.

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.
