The Catalyst® 3508G XL eight-port stackable Gigabit Ethernet switch is a member of Cisco Systems Catalyst 3500 series XL, a scalable line of stackable 10/100 and Gigabit Ethernet switches that delivers premium performance, manageability, and flexibility with unparalleled investment protection.
The Catalyst 3508G XL switch features eight gigabit interface converter (GBIC)-based 1000BaseX ports and a 10-Gbps switching fabric. These features make this switch ideal for wiring closet aggregation of 10/100 switches with Gigabit Ethernet uplinks and Gigabit Ethernet servers. Available in Standard and Enterprise editions, the Catalyst 3508G XL switch is software upgradable, so your investment is protected and your LAN can grow and evolve with your network requirements. The switch is easy to deploy, either on a desktop or in a wiring closet, and features Cisco IOS® software support.
The Catalyst 3508G XL is a Gigabit Ethernet aggregation switch that provides eight GBIC-based Gigabit Ethernet ports and a 10-Gbps switching fabric, making it an ideal solution for aggregating LAN segments and connecting to the network backbone.
Cisco Systems, the leader in internetworking solutions, provides the industry's most flexible, scalable, and manageable stacking architecture for Catalyst 3500 series XL and gigabit-enabled Catalyst 2900 series XL switches.
The Catalyst 3500 series XL and gigabit-enabled Catalyst 2900 series XL switches can be stacked using the low-cost Cisco GigaStack GBIC. The two-port GigaStack GBIC offers a range of highly flexible stacking and performance options. It delivers 1-Gbps connectivity in a daisy-chained configuration or up to 2-Gbps full-duplex connectivity in a dedicated, switch-to-switch configuration.
In addition, Cisco takes stacking to a new level with Switch Clustering technology. This breakthrough technology enables up to 16 interconnected Catalyst 3500 XL, 2900 XL, and Catalyst 1900 switches, regardless of geographic proximity, to form a managed, single-IP address network. These switches can be clustered using a broad range of connectivity options to deliver different levels of performance to meet customers' requirements. Clustering connectivity options for the Catalyst 3508G XL include low-cost Cisco GigaStack GBIC, Gigabit Ethernet, and Gigabit® EtherChannel. Because Cisco Switch Clustering technology is not limited by proprietary stacking modules and stacking cables, it expands the traditional stacking domain beyond a single wiring closet, and lets users "mix and match" interconnections to meet their specific management, performance, and cost requirements.
Catalyst 3500 XL switches can be configured either as command or member switches in a Cisco switch stack or cluster. The command switch serves as the single IP address management point and disburses all management action dictated by the network administrator. Command switches can cluster up to 15 additional interconnected member switches, regardless of their interconnection media. The Catalyst 3508G XL is an optimal command switch when deployed as a high-performance aggregator.
The Catalyst 3508G XL features a Web-based Cisco management tool, Cisco Visual Switch Manager (CVSM), which allows network administrators to view and manage the switch from anywhere on the network through a standard browser such as Microsoft Internet Explorer or Netscape Navigator. Launched from the switch itself, CVSM delivers simple network- and device-level management, including port configuration, virtual LAN (VLAN) setup, network views, and port monitoring. CVSM is an integral part of the Cisco scalable stacking architecture, allowing users to easily configure and manage stacks and switch clusters, and administer software upgrades across multiple switches.
Cisco Catalyst 3500 series XL Standard Edition switches include several exceptional features to increase network performance, manageability, and security. The command switch feature delivers single-IP managed Cisco Switch Clustering technology for up to 16 interconnected Catalyst 3500 XL, 2900 XL, and Catalyst 1900 switches. Gigabit EtherChannel technology offers higher-performance bandwidth between Catalyst switches, routers, and servers. Cisco Group Management Protocol (CGMP) enhances performance of multimedia applications and reduces network traffic by allowing a switch to selectively and dynamically forward IP multicast traffic to targeted end stations. Up to 250 port-based VLANs per switch allow data packets to be forwarded only to stations within a specific VLAN, creating a virtual firewall between groups of ports on the network. Network Time Protocol (NTP) provides a unified clock across the network, ensuring accurate time stamps for troubleshooting all network events. Media Access Control (MAC)-based port-level security prevents unauthorized stations from accessing the switch. Multi-layer security on the switch console prevents unauthorized users from gaining access and altering the switch configuration. All Standard Edition switches can be upgraded with the purchase of an optional Enterprise Edition upgrade kit.
Enterprise Edition software includes all the features of the Standard Edition, and adds enhanced end-to-end VLAN support to your Catalyst 3500 series XL switch. Virtual LAN trunks can be created from any port using either 802.1Q trunking or the Cisco Inter-Switch Link (ISL) VLAN architecture. VLANs using standards-based 802.1Q and ISL trunking provide broadcast control and enhanced security, and simplify adds, moves, and changes. TACACS+ authentication enables centralized access control of the switch and restricts unauthorized users from altering the configuration. Uplink Fast technology ensures quick failover recovery, enhancing overall network stability and reliability. An Enterprise Edition switch is the best choice for a network requiring a higher level security, superior fail-safe redundancy, and end-to-end VLANs spanning multiple routers, switches, and access servers.
