Cisco Switch Clustering

Breakthrough Cisco Switch Clustering technology enables up to

16 interconnected Catalyst 3500 XL, 2900 XL, and Catalyst 1900

switches, regardless of geographic proximity, to form a single IP

management domain. Switch Clustering supports a broad range of

standards-based connectivity options and conﬁgurations to

deliver levels of performance that are scalable to meet customer

requirements. Switch Clustering connectivity options for the

Catalyst 3500 series XL include Ethernet, Fast Ethernet, Fast

EtherChannel ports, low-cost Cisco GigaStack GBIC, Gigabit

Ethernet, and Gigabit EtherChannel ports. Because the

technology is not limited by proprietary stacking modules and

stacking cables, Cisco Switch Clustering expands the traditional

stacking domain beyond a single wiring closet and lets users mix

and match interconnections to meet speciﬁc management,

performance, and cost requirements (Figure 2).

Cisco Switch Clustering can be accessed via a Web-based

management interface, which allows network administrators to

configure, monitor, and manage a switch from anywhere on the

network through a standard browser such as Microsoft Internet

Explorer or Netscape Navigator. Network administrators simply

point their Web-browsers to the IP address of the cluster Command

switch and access all management capabilities. The Web-based

interface is launched from the switch itself and delivers simple,

cluster-wide, device-level management, including port

configuration, VLAN setup, network views, and port

monitoring—all from a single graphical interface. Web-based

management is an integral part of the Cisco Switch Clustering

architecture, allowing users to easily configure and manage stacks

and switch clusters, and administer software upgrades across

multiple switches. Command switch and cluster management

redundancy are ensured via an automatic failover scheme (Q1’00

software update) in the rare event of a command switch failure.
