Cisco 7600 Series Router Supervisor Engine and Route Switch Processor Guide
OL-10100-04
Chapter 2 Route Switch Processors and Supervisor Engines
RSP720 with 10GE Uplink Ports
• High-availability features such as NonStop Forwarding with Stateful Switchover (NSF/SSO) and
In-Service Software Upgrade (ISSU) are not supported. Only Route Processor Redundancy (RPR)
mode is supported.
• The uplinks on the standby RSP720-10GE are not active. This restriction exists because the uplink
ports must perform lookups on the active RSP, which is not possible in RPR mode.
• Intelligent Service Gateway is not supported.
• Device authentication to prevent counterfeiting
• Keystore controller for key authentication
• Virtual switch functionality
RSP720-10GE Usage Guidelines and Limitations
Observe the following guidelines when using the RSP720-10GE:
• The RSP720-10GE runs the same Cisco IOS software images as the RSP720. The following
software image feature sets are available for the RSP720-10GE: ipservices, ipservicesk9,
advipservices, advipservicesk9, and adventerprisek9.
• Line cards require new firmware to operate with the RSP720-10GE. If a line card does not have the
correct firmware, an error message is displayed on boot-up and the line card is powered off.
• The RSP720-10GE uses new ROMMON software for both the SP and RP. Because the
RSP720-10GE and RSP720 use a different IO memory map, the RSPs cannot share the same
ROMMON software.
–
If you attempt to load RSP720 ROMMON software onto the RSP720-10GE, the RSP720-10GE
does not power up and the ROMMON banner is not displayed.
–
If you load RSP720-10GE ROMMON software onto the RSP720, Cisco IOS software boots up
but the software detects a mismatch and enters ROMMON mode.
• You can configure the RSP720-10GE to run QoS features on all uplink ports (10GE and 1GE) or on
10GE ports only. A new CLI command (mls qos supervisor 10g-only) is available to configure the
module to run QoS features on 10GE ports only. QoS operates differently in each mode. See the
“QoS on the RSP720-10GE” section on page 2-10 for more information.
QoS on the RSP720-10GE
The RSP720-10GE has both 10GE and 1GE uplink ports. You can configure the RSP720-10GE to run
QoS features on all uplink ports (mixed mode) or on 10GE ports only. The number of queues available
for QoS depends on which mode is used:
• In mixed mode (10GE and 1GE ports), the default, only four queues are available for QoS.
The QoS port architecture for 1GE ports is (Rx/Tx): 2q8t/1p3q8t.
