GBIC-based Gigabit Ethernet ports; and the Catalyst 3548 XL has
48 10/100 ports and two GBIC-based Gigabit Ethernet ports. The
built-in Gigabit Ethernet ports accommodate a range of GBIC
transceivers, including the Cisco GigaStack™ GBIC, and
1000BaseSX,1000BaseLX/LH and 1000BaseZX GBICs. The
dual GBIC-based Gigabit Ethernet implementation provides
customers tremendous deployment flexibility—allowing
customers to implement one type of stacking and uplink
configuration today, while preserving the option to migrate that
configuration in the future.
The Catalyst 3500 XL switches are ideal for providing
desktop connectivity in a variety of network applications. The
12-port Catalyst 3512 XL offers low port density at a low entry
price. Catalyst 3524 XL and Catalyst 3548 XL switches deliver
dedicated 10- or 100-Mbps bandwidth to individual users and
servers at a low per-port price. All three desktop switches have
dual GBIC-based Gigabit Ethernet ports that provide an
ultra-flexible and scalable solution for Gigabit Ethernet uplinks or
GigaStack GBIC stacking solutions. The switches are easy to
deploy, either on a desktop or in a wiring closet, and feature Cisco
IOS® software support. Administration of Cisco desktop Catalyst
switches is made even more convenient using the Cisco Switch
Clustering multidevice management technology.
Flexible Stacking with the GigaStack GBIC
The Catalyst 3500 series XL and Gigabit Ethernet-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. Customers can deploy a 1-Gbps independent stack
backplane in a cascade configuration, or scale up to 5-Gbps of
bandwidth in a star configuration using the Catalyst 3508G XL
Gigabit Ethernet aggregation switch. Network managers may use
one or both of the available GBIC ports to create high-speed
uplinks to the network core, using standard Gigabit Ethernet or
Gigabit EtherChannel® technology. High levels of stack resiliency
can also be implemented by deploying dual redundant Gigabit
Ethernet Uplinks, a redundant GigaStack loopback cable, Uplink
or member switches in a Cisco switch stack or cluster. The
Fast for high-speed uplink failover, and per VLAN Spanning Tree
command switch serves as the single IP address management
(PVST+) for uplink load balancing. This Gigabit Ethernet
point and disburses all management instructions dictated by the
flexibility makes the Catalyst 3500 series XL an ideal LAN edge
network administrator. Command switches can cluster up to 15
complement to the Cisco Catalyst 6500 family of Gigabit
