Permanent password assignment


Permanent password assignment

When you log in for the first time, Brocade recommends that you change the passwords for the
default accounts.

The factory-configured default accounts on the switch are admin, user, and root. Use the default
administrative account as shown in

Table 2

to log in to the switch for the first time and to perform

the basic configuration tasks.

The root account is reserved for development and manufacturing. The user account is read-only
and used primarily for system monitoring.

Changing the default account passwords

When you change the default account password after you log in for the first time, only the default
password rule is in effect. The rule specifies a minimum password length of eight characters. For
advanced user and role management, including setting password rules, refer to the Security
chapter of the Brocade Network OS Administrator’s Guide.

Setting the switch IP address

You can configure the Brocade VDX 6740 switches with a static IP address, or you can use a
Dynamic Host Configuration Protocol (DHCP) server to set the IP address of the switch. DHCP is
enabled by default. The Brocade VDX 6740 switches support both IPv4 and IPv6 format addresses.

Using DHCP to set the IP address

When using DHCP, the Brocade VDX 6740 switches obtain the IP address, subnet mask, and
default gateway address from the DHCP server. The DHCP client can only connect to a DHCP server
that is on the same subnet as the switch. If your DHCP server is not on the same subnet as the
Brocade VDX 6740, use a static IP address.

To set an IPv4 IP address using DHCP, complete the following steps.

1. Log in to the switch using the admin account.

2. Configure the management interface with the following command:
