OER Border Router Only Functionality
In Cisco IOS Release 12.2(33)SXH support for using a Cisco Catalyst 6500 series switch as an OER
border router was introduced. Only border router functionality is included in the Cisco IOS Release
12.2(33)SXH images; no master controller configuration is available. The master controller that
communicates with the Cisco Catalyst 6500 series switch being used as a border router must be a router
running Cisco IOS Release 12.4(6)T or a later release. The OER master controller software has been
modified to handle the limited functionality supported by the Cisco Catalyst 6500 border routers. Using
the Route Processor (RP), the Catalyst 6500 border routers can capture throughput statistics only for a
traffic class compared to the delay, loss, unreachability, and throughput statistics collected by
non-Catalyst 6500 border routers. A master controller automatically detects the limited capabilities of
the Catalyst 6500 border routers and downgrades other border routers to capture only the throughput
statistics for traffic classes. By ignoring other types of statistics, the master controller is presented with
a uniform view of the border router functionality.
