For example, if the Call Server’s PWD1 is “0000”, it is padded to the right
with the four space characters to become “0000 ”. This is done
automatically by the software. It is not necessary to manually add the spaces.
Password Updates
The Call Server’s PWD1 user ID and password is sent to all Voice Gateway
Media Cards at the following times:
• when the Voice Gateway Media Cards initially establish a connection
with the Call Server across the ELAN subnet
• when an EDD operation is performed on the Call Server
Once the PWD1 information is downloaded from the Call Server, it is saved
in the Voice Gateway Media Card’s NVRAM. If a Voice Gateway Media
Card has not yet established a link with the ELAN subnet, the user ID and
password that are currently stored in the card’s NVRAM are used to log in.
The user ID and password might not match the PWD1 on the Call Server
because the Call Server has not yet downloaded the current PWD1 to the
Voice Gateway Media Card. Once the ELAN subnet connection is
established, the user ID and password are synchronized on all Voice Gateway
Media Cards, and the new user ID and password are saved in the card’s
NVRAM.
Since all Voice Gateway Media Cards automatically receive the user ID and
password from the Call Server, the password can be changed in a single
location, the Call Server’s CLI. This eliminates the need to change the
password on every card in the node (just change the password once on the
Call Server). When the password is changed at the Call Server, the password
is automatically sent to all the Voice Gateway Media Cards.
A user can change the user ID and password login on any card using the
shellPasswordSet CLI command. However, updates from the Call Server
overwrite the cards’ user ID and password in the NVRAM.
