Avoiding Command Mode Authorization Issues with RPM
Cisco Route Processor Module (RPM) cards are router cards that can be installed in Cisco MGX
switches. The switch has its own operating system and so does each RPM card installed in the switch.
When command mode authorization is enabled, RPM login names, passwords, and commands must be
authorized by the AAA server and the RPM operating system, which is IOS. If users establish Telnet
sessions from an RPM card to a different operating system (such as a UNIX host running CWM), all
commands for the additional operating system must be authorized by the AAA server and that operating
system.
The switch software provides a special command to prevent redundant authorization and the enormous
amount of configuration that would be required to configure the AAA server for multiple operating
systems. The cnfaaa-ignore-ios command configures the switch to exclude select slots from
authentication and authorization when the slots host RPM cards.
To enable or disable switch authentication and authorization for slots that host RPM cards, log in using
a username with SERVICE_GP privileges or higher and enter the cnfaaa-ignore-ios command in the
following format:
M8850_LA.7.PXM.a >
cnfaaa-ignore-ios
add|del [
slot
]
Enter the add keyword to add the selected slot or slots to the list of slots that are ignored for switch
authentication and authorization when an RPM card is installed. Enter the del keyword to delete the
selected slot or slots from the ignored list. If you specify a slot, the command applies to only that slot.
If you do not specify a slot, the command applies to all slots in the switch.
The following example configures the switch to ignore switch authentication and authorization for card
slot 3 when an RPM card is inserted in that slot:
M8830_SF.2.PXM.a >
cnfaaa-ignore-ios
add 3

Verifying PXM Disk Data

match.
