Command Groups Introduction The Command Line Interface (CLI) is a network management application operated through an ASCII terminal without the use of a Graphic User Interface (GUI) driven software application. By directly entering commands, the user has greater configuration flexibility. The CLI is a basic command-line interpreter similar to the UNIX C shell.
Command Groups The system commands can be broken down into three sets of functional groups, Layers 2, Layer 3, and Utility. Table 1-1. System Command Groups Command Group Description Layer 2 Commands Configures connection security including authorization and passwords. Configures and displays ACL information. Address Table Configures bridging address tables.
(continued) Table 1-1. System Command Groups Command Group Description IPv6 MLD Snooping Configures IPv6 Snooping Querier and displays IPv6 Querier Snooping Querier information. Link Dependency Configures and displays link dependency information. LLDP Configures and displays LLDP information. Port Aggregator Provides server administrators the ability to map internal ports to external ports easily.
(continued) Table 1-1. System Command Groups Command Group Description Loopback Interface Manages Loopback configurations. (IPv6) Multicast (Mcast) Manages Multicasting on the system. OSPF (IPv4) Manages shortest path operations. OSPFv3 (IPv6) Manages IPv6 shortest path operations. Router Discovery Manages router discovery operations. Protocol (IPv4) Routing Information Configures RIP activities.
(continued) Table 1-1. System Command Groups Command Group Description RMON Can be configured through the CLI and displays RMON information. Serviceability Tracing Controls display of debug output to serial port or telnet console. sFlow Configures sFlow monitoring. SNMP Configures SNMP communities, traps and displays SNMP information.
