Cisco Systems RSP7000

36 7000 Series Route Switch Processor (RSP7000) Installation and Conﬁguration in the Cisco 7000 Series Routers

Reference Information

Table7 Default Boot Filenames

Bit 8 controls the console Break key. Setting bit 8 (the factory default) causes the processor to ignore

the console Break key. Clearing bit 8 causes the processor to interpret the Break key as a command

to force the system into the bootstrap monitor, thereby halting normal operation. A break can be sent

in the ﬁrst 60 seconds while the system reboots, regardless of the conﬁguration settings.

Bit 9 controls the secondary bootstrap program function. Setting bit 9 causes the system to use the

secondary bootstrap; clearing bit 9 causes the system to ignore the secondary bootstrap. The

secondary bootstrap program is used for system debugging and diagnostics.

Bit 10 controls the host portion of the IP broadcast address. Setting bit 10 causes the processor to

use all zeros; clearing bit 10 (the factory default) causes the processor to use all ones. Bit 10 interacts

with bit 14, which controls the network and subnet portions of the broadcast address.

Table8 shows the combined effect of bits 10 and 14.

Table8 Conﬁguration Register Settings for Broadcast Address Destination

Bits 11 and 12 in the conﬁguration register determine the baud rate of the console terminal. Table9

shows the bit settings for the four available baud rates. (The factory-set default baud rate is 9600.)
