The Cisco Catalyst 6500 Series offers advanced network-management features to make it easy
to manage fast-growing networks. This includes TDR supported on the new 48-port 10- and 100-
Mbps and all the 48-port 10-, 100-, and 1000-Mbps Ethernet modules (part numbers WS-X6148A-
RJ-45, WS-X6148A-45AF, WS-X6148A-GE-TX, WS-X6148A-GE-45AF, WS-X6148-GE-TX,
WS-X6548-GE-TX, and WS-X6748-GE-TX, respectively). TDR tests cabling by sending a
signal down the cable, reporting cable breaks, cable crimps, and improperly wired cable.
All Ethernet modules support extensive interface-level statistics, including four RMON groups:
alarms, events, history, and statistics. Additional RMON groups (all nine groups) can be monitored
using the integrated Cisco Catalyst 6500 Series Network analysis Module (NAM) or switch probes.
For in-depth network analysis, the Switched Port Analyzer (SPAN) feature helps network
managers redirect traffic from each switched port to a specific VLAN, allowing them to add, move,
and easily change group access to network resources from centralized locations using
CiscoWorks network-management software.
Support for local, out-of-band management is delivered through a terminal or modem attached
to the console or auxiliary interface of the supervisor engine. Remote in-band management is
available with SNMP Versions 1, 2, and 3.
Cisco Catalyst 6500 Series 10/100 and 10/100/1000 Modules
Cisco Catalyst 6500 Series 10/100 and 10/100/1000 Ethernet interface modules feature three
classes of forwarding architectures and switch-fabric interconnections, classic, Cisco Express
Forwarding 256, and Cisco Express Forwarding 720, to provide a choice of speeds and forwarding
rates. Table 2 highlights the primary differences in the three classes of forwarding and switch-
fabric architectures.
