Understanding Tools and Options
•
Restore a corrupted file system
The BayStack router’s file system resides on an installed flash memory card.
With Netboot enabled, the BayStack router can still boot over the network if
the local files become corrupted. (When the BayStack router reboots due to a
reset or power loss, it automatically boots the configuration and image files
over the network if it cannot find intact files locally.)
•
Obtain application and string files from the BootP server as the BayStack
router needs them
Obtaining these files individually, rather than obtaining the entire an.exe or
arn.exe file, reduces line costs and the use of flash memory space.
The Netboot procedure requires the following at initial startup:
•
A communications link between the BayStack router and an upstream router
over an Ethernet, HDLC, Frame Relay, or token ring (ARN only) interface
•
A local console or modem connection with the BayStack router
•
A BootP server that contains the operating-system kernel (krnl_arn.exe for the
ARN or krnl_an.exe for the AN/ANH) or a network configuration file
customized for the BayStack router
•
An IP address assigned to the BayStack router boot interface
Directed Netboot
The Directed Netboot procedure requires the following at initial startup:
•
A communications link between the BayStack router and an upstream router
over an Ethernet, HDLC, Frame Relay, or token ring (ARN only) interface
•
A local console or modem connection with the BayStack router
•
A TFTP server that contains the kernel file (krnl_arn.exe for the ARN or
krnl_an.exe for the AN/ANH) or a network configuration file customized for
the BayStack router
Compared with Netboot, Directed Netboot offers the following advantages:
