CONFIGURING THE SWITCH

Filtering Addresses for Management Access

You create a list of up to 16 IP addresses or IP address groups that are allowed management access to the switch through the web interface, SNMP, or Telnet.

Command Usage

The management interfaces are open to all IP addresses by default. Once you add an entry to a filter list, access to that interface is restricted to the specified addresses.

If anyone tries to access a management interface on the switch from an invalid address, the switch will reject the connection, enter an event message in the system log, and send a trap message to the trap manager.

IP address can be configured for SNMP, web and Telnet access respectively. Each of these groups can include up to five different sets of addresses, either individual addresses or address ranges.

When entering addresses for the same group (i.e., SNMP, web or Telnet), the switch will not accept overlapping address ranges. When entering addresses for different groups, the switch will accept overlapping address ranges.

You cannot delete an individual address from a specified range. You must delete the entire range, and reenter the addresses.

You can delete an address range just by specifying the start address, or by specifying both the start address and end address.

Command Attributes

Web IP Filter – Configures IP address(es) for the web group.

SNMP IP Filter – Configures IP address(es) for the SNMP group.

Telnet IP Filter – Configures IP address(es) for the Telnet group.

IP Filter List – IP address which are allowed management access to this interface.

Start IP Address – A single IP address, or the starting address of a range.

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.
