When you log in to an IRF fabric, you are placed at the CLI of the master, regardless of at which
member switch you are logged in. After that, you can access the CLI of a subordinate switch to
execute a limited set of maintenance commands.
The IRF fabric supports up to 16 concurrent VTY users. The maximum number of concurrent
console users equals the total number of member switches in the IRF fabric.
Accessing the CLI of the master switch
Access an IRF fabric in one of the following ways:
•
Local
login
—Log in through the console port of any member switch.
•
Remote
login
—Remotely log in at a Layer 3 Ethernet interface on any member switch by using
a methods including Telnet, Web, and SNMP.
For more information, see the chapter on login in
Fundamentals Configuration Guide

subordinate switch, you are placed in user view, and the command prompt changes to
<Sysname-Slave#member-ID/slot-number>
, for example, <Sysname-Slave#2>. You can use the
following commands at a subordinate switch's CLI:
•
display
•
quit
•
return
•
system-view
•
debugging
•
