CLI commands for IS-IS discovery

The CLI commands for IS-IS discovery is applicable only for IPv4 network. Discovery of IS-IS object in an IP v6 network is SNMP-based.
Because the standards-based IS-IS MIB is used by Juniper devices but not by Cisco devices,
uses SNMP discovery and SNMP polling to discover and monitor the IS-IS topology for Juniper devices, and uses CLI discovery and CLI polling to discover and monitor the IS-IS topology for Cisco devices. The CLI commands that are invoked for IS-IS discovery are identified in this section, and the CLI commands that are invoked for IS-IS monitoring are identified in the
.
establishes Telnet, SSH1, or SSH2 sessions to the Cisco devices and invokes specific CLI "show" commands to discover the following routing topology objects and their relationships:

Command
Description
terminal length 0
Prevents the Cisco device from pausing between multiple screens of output.
During the session, the Cisco device uses the terminal length value to determine when to pause during multiple-screen output. A value of 0 prevents the device from pausing between screens of output.
