Configuration Tasks<br />
Command Purpose<br />
Step 3 Perform this step on <strong>Cisco</strong> 7500 series devices only: Specifies the image to be used by the active RSP at<br />
hw-module slot slot-number image file-spec<br />
initialization. If a high-availability image is found,<br />
the running configuration is updated.<br />
Example:<br />
Router(config)# hw-module slot 6 image slot0:rsp-pv-mz<br />
Step 4 Perform this step on <strong>Cisco</strong> 7500 series devices only:<br />
hw-module slot slot-number image file-spec<br />
Example:<br />
Router(config)# hw-module slot 7 image slot0:rsp-pv-mz<br />
Step 5 redundancy<br />
Example:<br />
Router(config)# redundancy<br />
Step 6 mode {hsa | rpr | rpr-plus | sso}<br />
Example:<br />
Router(config-red)# mode sso<br />
• slot-number—Specifies the standby RSP slot<br />
where the Flash memory card is located. Valid<br />
numbers are slot 2 or slot 3 for a <strong>Cisco</strong> 7507<br />
router or slot 6 or slot 7 for a <strong>Cisco</strong> 7513 router.<br />
• file-spec—Indicates the Flash device and the<br />
name of the image on the standby RSP.<br />
Note Steps 3 and 4 are the same. Step 3 applies<br />
to the active RSP, and Step 4 applies to the<br />
standby RSP.<br />
If you do not specify a <strong>Cisco</strong> IOS image in Step 3,<br />
this command loads and executes the bundled<br />
default <strong>Cisco</strong> IOS standby image. The system then<br />
operates in HSA mode.<br />
The image indicated by the file-spec attribute must<br />
be available on the local Flash device. Remote<br />
protocols such a TFTP and remote copy are not<br />
available.<br />
Specifies the image to be used by the standby RSP<br />
at initialization. If a high-availability image is<br />
found, the running configuration is updated.<br />
• slot-number—Specifies the active RSP slot<br />
where the Flash memory card is located. Valid<br />
numbers are slot 2 or slot 3 for a <strong>Cisco</strong> 7507<br />
router or slot 6 or slot 7 for a <strong>Cisco</strong> 7513 router.<br />
• file-spec—Indicates the Flash device and the<br />
name of the image on the active RSP.<br />
Note Steps 3 and 4 are the same. Step 3 applies<br />
to the active RSP, and Step 4 applies to the<br />
standby RSP.<br />
The image indicated by the file-spec attribute must<br />
be available on the local Flash device. Remote<br />
protocols such a TFTP and rcp are not available.<br />
Enters redundancy configuration mode.<br />
Sets the redundancy configuration mode to SSO on<br />
both the active and standby RP.<br />
Note After configuring SSO mode, the standby<br />
RP will automatically reset.<br />
