Creating Users Guidelines

<a name="wp1074352"> </a><p class="pBody">
The passphrase specified in the <b class="cBold">snmp-server user</b> option and the password specified <b class="cBold">username </b>option 
are synchronized.

</p>
<a name="wp1074356"> </a><p class="pBody">
By default, the user account does not expire unless you explicitly configure it to expire. The <b class="cBold">expire</b> 
option determines the date on which the user account is disabled. The date is specified in the 
YYYY-MM-DD format.

</p>
<a name="wp1074357"> </a><p class="pBody">
When creating users, note the following guidelines:

</p>
<div class="pSmartList1"><ul class="pSmartList1">
<a name="wp1074358"> </a><li class="pSmartList1">You can configure up to a maximum of 256 users on a switch.
</li>
<a name="wp1074360"> </a><li class="pSmartList1">The following words are reserved and cannot be used to configure users: bin, daemon, adm, lp, sync, 
shutdown, halt, mail, news, uucp, operator, games, gopher, ftp, nobody, nscd, mailnull, rpc, rpcuser, 
xfs, gdm, mtsuser, ftpuser, man, and sys.
</li>
<a name="wp1074361"> </a><li class="pSmartList1">User passwords are not displayed in the switch configuration file.
</li>
<a name="wp1074362"> </a><li class="pSmartList1">If a password is trivial (short, easy-to-decipher), your password configuration is rejected. Be sure to 
configure a strong password as shown in the sample configuration. Passwords are case-sensitive. 
“admin” is no longer the default password for any Cisco MDS 9000 Family switch. You must 
explicitly configure a strong password.

<strong>Caution	&nbsp;&nbsp;&nbsp;</strong>
</td>

<p>Cisco MDS NX-OS supports user names that are created with alphanumeric characters or specific 
special characters (+ [plus], = [equal], _ [underscore], - [hyphen], \ [backslash], and . [period]) whether 
created remotely (using TACACS+ or RADIUS) or locally. Local user names cannot be created with any 
special characters (apart from those specified). If a non-supported special character user name exists on 
an AAA server, and is entered during login, then the user is denied access.
