Setting the switch IP address
You can configure the Brocade VDX 6730 with a static IP address, or you can use a DHCP (Dynamic Host
Configuration Protocol) server to set the IP address of the switch. DHCP is enabled by default. The Brocade VDX
6730 supports both IPv4 and IPv6 format addresses. For information about setting static IP addresses and
stateless IPv6 addresses, please see the Brocade Network OS Administrator’s Guide.
Using DHCP to set the IP address
When using DHCP, the Brocade VDX 6730 obtains its 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 6730, use a static IP address. For information on
how to set the IP address using a static IP address, please refer to the Brocade VDX 6730 Hardware Reference
Manual.
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:
switch(config)# interface Management 1/0
3. Configure the IP address using the following command:
switch(config-Management-1/0)# ip address dhcp
Enabling and disabling Brocade VCS mode
Enable or disable a single switch for VCS™ mode as soon as passwords have been assigned and an IP address has
been set. Enabling VCS mode is disruptive because a reboot is required once the mode has been enabled. Enabling
or disabling VCS mode also causes the default configuration file for that mode to be applied. The Brocade VDX 6730
ships with a two-node VCS license by default. VCS mode is disabled by default.
The basic configuration tasks include enabling or disabling VCS mode explicitly, setting VCS parameters, and
applying the default configuration. If you disable VCS mode, you do not have to set the other parameters. For more
details about enabling VCS mode and setting VCS parameters, refer to the Brocade Network OS Administrator’s
Guide and the Brocade Network OS Command Reference.
Enabling VCS mode
Perform the following steps to enable VCS mode.
1. Log in to the switch using an account that has the admin role.
2. Enter the vcs enable command, including the RBridge parameter, as in the following example.
vcs rbridge-id 1 enable
The switch reboots when you confirm that you want to enable VCS mode.
When the switch comes back up, if it is connected to other VCS-enabled switches, the negotiation protocols
begin, determining which switch in the fabric is the principal switch and making sure that all domain IDs, and
therefore RBridge IDs, are unique. Should the insistent domain ID not be unique, you can change it. Once the
domain IDs are determined to be unique, they are equated to the RBridge IDs.
