3Com OfficeConnect Remote 812 manual Conventions Command Language Terminology

VC - A table of parameters that describes connection parameters associated with a remote site. These parameters are used when establishing a network connection over the WAN.

User - A table of parameters that describes connection parameters associated with Telnet users that wish to attach and remotely manage the unit.

Filter - can be applied to interfaces, connections, and users to control access through the system

Interface - describes physical devices; for example, ports Syslog Host - receives system messages

Network - defines local and remote networks, network connections, hosts and routers

Elements like vc’s and users must be disabled before changes to these elements can be implemented.

Wherever an IP address value is required, you can enter a host name provided you have configured a DNS server or put the name and address into the DNS Local Host table.

￿￿￿The CLI command language creates, manages, displays and removes system entities. These entities describe system and network connections and processes. Most of the managed entities in the system are slotted in tables. Some common examples are:

￿

Commands to delete a network user, interface, route, TCP connection, community name, network service and others cannot take place unless the process or function has first been disabled.

Help is most useful during configuration: query the list of possible parameters by typing ? and, when you find the value you need, type it without losing your place in the argument. Just be sure to leave a space between the keyword and the question mark.

Most commands are not case sensitive. As a rule, only <name> and [password] ￿values require typing the correct case.

Configuration changes occur immediately but are lost on reboot unless you save them. The save all command places configuration changes in FLASH ROM (permanent memory). The changes are lost if not saved to FLASH ROM or if power is lost before you can save them.

DNS Server - translates IP addresses to and from host names

￿Route - describes a path through the network to another system or network

Table entries are created with an add command, and removed with a delete command. The add command specifies the most important parameters of the entry. Additional parameters are usually specified with the set command, which is also used to change configured parameters.

The list command displays table entries. For example, list users displays all defined administrative login profiles. The show command displays detailed information about a specific table entry. For example, show user root displays detailed information for the administrative login profile root.
