Access Control
This chapter describes how to control access to the OMC.
13.1 About Access Control
A console port and FTP are allowed one session each, Telnet and SSH share four sessions, up
to five web management sessions (five different usernames and passwords) and/or limitless
SNMP access control sessions are allowed.
When multiple login is disabled and there is already a console port session, you cannot telnet
to the OMC. The following error message displays.
If you disable multiple login while another administrator is accessing the OMC via telnet, the
OMC will immediately log out the administrator and disconnect the telnet session. The
following error message displays.
See Section 19.2.1 on page 146 for more information on disabling multi-login.
