Command History
Release 3.1 Command was introduced.
Functional Notes
The current single-pair high-speed digital subscriber line (SHDSL) network interface module (NIM) card
(P/N 1200867L1) supports two code images commonly referred to as the active image and the inactive
image. When a firmware upgrade is performed on the card (through the copy <filename> interface shdsl
x/y Enable mode command), the new firmware is placed in the inactive image space. This new code will
not be executed until the boot alternate-image command is issued. When the user does this, the NIM will
reboot (taking the current line down) with the new code. At this point, the old code becomes the inactive
image and the new recently updated code becomes the active image.
Usage Examples
The following example causes the firmware upgrade to take effect:
(config)#interface shdsl 1/1
(config-shdsl 1/1)#boot alternate-image
