Hello, everyone!
Today, I will continue to explain a new topic – GPON OLT basic operations. Now I will introduce command line features.
The system distinguishes several levels of operation on OLT and ONUs (MxUs, MDUs). Each level has certain commands that work at that level. The goal of all this is to have a hierarchy and prevent unauthorized access.
There are the following command modes:
user mode,
privilege mode,
global config mode,
config mode interface,
OSPF mode,
MPLS-LDP mode, and
BTV mode.
The figures above show everything nicely, when moving from one level to another, how it returns and exits the system.
The sign ? is used as a help command. It can be used at all levels of work. Displays a list of commands at that level with a brief description of each. For example:
TEST(config)#?
We can use the ? character at half command and thus get all the commands that start with those letters with a short description. For example:
TEST(config)#int?
We can use the ? character at half command and thus get all the commands that start with those letters with a short description. In addition, we can use the ? character even when I don't know or have forgotten further commands. For example:
TEST(config)#interface ?
While typing comments, we can use the space key to supplement the commands we started. This significantly speeds up the work during configuration. If there are multiple commands, one or more letters are required.
The #interface eth command is used to enter and configure ETH ports. It's ETH mode. The #interface gpon command is a command used to enter GPON mode to configure GPON ports. The #interface vlanif command is used to create and configure a VLANIF interface. It's VLANIF mode. This mode supports the configuration of DHCP, IP address and DHCP server.
This is the end of this article. I will explain this topic in the next article >> GPON OLT Basic Operations (3).
Thank you!
