Configuring a Boot Configuration Record for the Passive SCM Chapter 2 Specifying the CSS Boot Configuration Configuring a Boot Configuration Record for the Passive SCM You can configure the individual components of the boot configuration record on the passive SCM installed in a CSS 11506 chassis. A passive module is a standby module in case of an active module failure. Use the passive command to configure the boot configuration record for the current passive SCM. The boot configuration record consists of the IP address, subnet mask, boot method, and boot file. Using the sync options for the passive command, copy the boot configuration record from the active SCM to the passive SCM. In most CSS configurations, the active and passive SCMs have the same boot record. The passive command also allows you to configure the individual components of the boot configuration record on the passive SCM. For example, you can configure a boot record on the passive SCM that has a software version that differs from the active SCM. The boot configuration record allows you to run a new software version on the active SCM and have an older software version on the passive SCM. You can also configure a different IP address on the passive SCM to track an active-to-passive state transition between the SCMs. You can track active-to-passive state transitions through a network management station, where you can receive SNMP host traps. The passive command and its options affect only the current passive SCM. When you configure the passive SCM, the set values are loaded in to its NVRAM. If the passive SCM transitions to the active state, it continues to retain these values, but is no longer affected by these commands; boot commands are not saved in the running-config file.
