CONFIGURING THE SWITCH

Configuring an Extended IP ACL

Command Attributes

•Action – An ACL can contain any combination of permit or deny rules.

•Source/Destination Address Type – Specifies the source or destination IP address. Use “Any” to include all possible addresses, “Host” to specify a specific host address in the Address field, or “IP” to specify a range of addresses with the Address and SubMask fields. (Options: Any, Host, IP; Default: Any)

•Source/Destination Address – Source or destination IP address.

•Source/Destination Subnet Mask – Subnet mask for source or destination address. (See the description for Subnet Mask on page 3-80.)

•Service Type – Packet priority settings based on the following criteria:

-Precedence – IP precedence level. (Range: 0-7)

-TOS – Type of Service level. (Range: 0-15)

-DSCP – DSCP priority level. (Range: 0-63)

•Protocol – Specifies the protocol type to match as TCP, UDP or Others, where others indicates a specific protocol number (0-255). (Options: TCP, UDP, Others; Default: TCP)

•Source/Destination Port – Source/destination port number for the specified protocol type. (Range: 0-65535)

•Control Code – Decimal number (representing a bit string) that specifies flag bits in byte 14 of the TCP header. (Range: 0-63)

•Control Code Bitmask – Decimal number representing the code bits to match. The control bitmask is a decimal number (for an equivalent binary bit mask) that is applied to the control code. Enter a decimal number, where the equivalent binary bit “1” means to match a bit and “0” means to ignore a bit. The following bits may be specified:

-1 (fin) – Finish

-2 (syn) – Synchronize

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.
