Stack 10/100 Ethernet switch High Availability

Ethernet switches are still commonly used, so I studied the high availability of stack 10/100 Ethernet switches. I would like to share with you here, hoping to be useful to you. Catalyst3524-PWRXL Ethernet switches are part of the CiscoSystemsCatalyst3500XL series, which is a series of scalable stack 10/100 and Gigabit Ethernet switches that provide optimal performance, manageability and flexibility, as well as unparalleled investment protection.

Advanced service quality QoS) is fully integrated with CiscoIP phones and high-availability network features. for customers who are preparing to develop and configure integrated voice, video, and data application LAN, catalyst3524-PWRXL is undoubtedly the best exchange solution.

The Catalyst3524-PWRXL switch has 24 10/100 switching ports and is equipped with a Gigabit Ethernet port that integrates internal power and two GBIC-based interfaces. The integrated internal power supply provides DC power for devices that use traditional unshielded dual-torsion UTP cables, such as Cisco7900 series CiscoIP phones. The implementation of GBIC-based dual-Gigabit Ethernet provides the customer with great deployment activity-allows the customer to implement a current stack and uplink configuration, at the same time, it reserves space for future configuration migration.

In the future, customers who want to deploy converged network applications must consider deploying LAN devices, such as switches that can support these increasing demands. Such switches should be able to process time-sensitive information, such as voice and key data information, with appropriate priority, to ensure that the network can be quickly recovered from network convergence or power failure. Catalyst3524-PWRXL is very convenient to deploy in traditional data LAN, and has advanced QoS and high availability features, so as to prepare for network operation voice, video and data fusion information. The Catalyst3524-PWRXL switch provides two built-in GBIC-based Gigabit Ethernet ports for 24 10/100 ports with integrated internal power and performance up to 7 million messages per second.

Service quality

All ipvst3500 series XL Ethernet switches support 802.1p service-level CoS based on IEEE and port priority-based LAN edge QoS. The Catalyst3524-PWRXL supports port-based multiclass classification, allows Ethernet switches to change the CoS settings of the identified information package based on each port, for unidentified information packages, an Ethernet switch can use the default incoming port priority to classify information packets. Priority settings are applied between queues to ensure that high-priority queues always receive services before low-priority information is arranged. These features allow users to apply critical task information, such as IP Voice (VoIP) and Enterprise Resource Planning ERP for general information, such as file transfer protocol (FTP) or set the priority level for low-priority web surfing information.

Ipvst3500xl and 2900XL Ethernet switches can automatically configure virtual VLAN for IP Phones) and trusted settings to overcome the management complexity caused by deploying a speech topology on a data network and maintaining voice quality information. Using the VLAN feature, network administrators can separate telephones into independent Logical Networks. Even if the data and voice infrastructure are the same, no impact will be given. The affiliated VLAN feature allows the phone to be placed in its own VLAN without any end user interruption. You only need to simply insert the phone into the switch, and the Ethernet switch can provide the required VLAN information to the phone. Trusted settings enable the switch to ensure that the voice information is obtained from the IP phone for high priority processing. You only need to control how the information is classified from linked devices.

High Availability

The ipvst3500 series XL switches provide several high-availability features based on hardware and software to prevent network interruptions and power outages, including internal power supply and advanced Spanning Tree fusion. The Catalyst3524-PWRXL provides 48 v dc power for standard 100 m UTP cables. On behalf of each desktop using Wall Power, IP phones and other terminal equipment such as IP phone using Catalyst3524-PWRXL switch power supply. The power supply provided by the Catalyst Switch Based on the phone search feature. With the telephone search feature, the Catalyst switch can automatically detect IP phone numbers and provide internal power. By deploying an uninterruptible power UPS Catalyst3524-PWRXL switch in a safe cabling room, network administrators can ensure that power outages do not constitute any agreement on the network telephone connection of the building.

When the basic link is paralyzed, the dual-gigabit uplink can provide the uplink redundancy function. Improved Spanning Tree fusion features, such as PortFast, UpLinkFast, and point-based Spanning Tree PVST) can ensure Rapid Spanning Tree fusion in the case of link failure. PVST allows users to implement redundant uplinks, and distributes information loads on multiple links-it is impossible to implement this by using standard shielded double torsion line STP. CiscoUplinkFast Technology ensures fast transmission to the second uplink, enhancing the overall network stability and reliability.

Software management features

Ciscoft-st3500 series XL Ethernet switches provide unique features to improve the performance and manageability of converged networks. To improve performance, express connect and Gigabit Ethernet channels provide high-performance bandwidth from Mbps to 4 Gbps between Catalyst switches, routers, and servers. Cisco Group Management Protocol CGMP) improves the performance of multimedia applications and reduces network traffic by allowing switches to provide IP multicast information to the destination end site selectively and dynamically.

Flexible stack functions of GigastackGBIC

The cost-effective CiscoGigaStackGBIC can be used to implement stacks for the ipvst3500 series XL and gigabit ethernet drive ipvst2900 series XL switches. The two-port GigaStackGBIC provides a series of highly flexible stack and performance options. You can deploy a 1 Gbit/s independent stack backplane in a cascade configuration, or use an ipvst3508xl Gigabit Ethernet switch to expand to 5 Gbit/s bandwidth in a star configuration. Network administrators can use standard Gigabit Ethernet or Gigabit Ethernet channel technology to create high-speed links to the core of the network with one of two GBIC ports. Deploy a dual-Gigabit Ethernet uplink, a redundant Gigastack loop cable, UplinkFast for high-speed failover, and PerVLANSpanningTree (PVST +) for uplink load balancing ), high Availability of stack devices. This one thousand MB Ethernet flexibility makes the ipvst3500xl series well-deserved an ideal LAN Edge product for ciscoft-st6500 series Gigabit Ethernet optimized core LAN switches.

Cisco switch Cluster

An empty and broken Cisco Ethernet switch cluster technology supports up to 16 inline ipvst3500xl, ipvst2900xl, and ipvst1900 Ethernet switches-an IP management domain without geographic considerations. Catalyst3500XL Series Switch cluster connection options include Ethernet, fast Ethernet, Fast Ethernet channel, low-cost CiscoGigaStackGBIC, Gigabit Ethernet and Gigabit Ethernet channel connections. Because technology is not limited to dedicated stack modules or stack cables, Cisco switch clusters can extend traditional stack domains beyond a single cabling room. The ipvst3500xl switch can be configured as a command or a member switch in the Cisco switch stack or cluster. The command switch can be used as a single IP address management point to allocate all management commands issued by the network administrator. A command switch can have up to 15 additional inline member switches in the cluster without the need for inline media.
