Startup Menu Procedures
The Startup menu can be entered when booting the
device. There is a two second window of time to enter the
Startup Menu immediately after the POST test. The menu
can be accessed directly from a terminal connected to the
console port. The Startup menu procedures can be done
using the ASCII terminal or Windows HyperTerminal.
The software download procedure is performed when a
new version must be downloaded to replace corrupted
files, update or upgrade the system software. To download

management functions can be limited to user groups,
which are defined by the following criteria:
Ingress interfaces
•
Source IP address and/or Source IP subnets.
•
ACE

which network traffic is forwarded. An ACE is based on the
following criteria:
Protocol
•
Protocol ID
•
Source Port
•
Destination Port
•
Wildcard Mask
•
Source IP Address
•
Destination IP Address
•
ACL (Access Control List)
