Brocade Communications Systems 6720 Configuring switch ports, Connecting network devices

Another parameters that can be changed if necessary is the VCS ID. This identifies the VCS fabric of which the switch can be a part. By default, the VCS of every VDX 6720 is 1. Change the VCS ID if you need to create a new, separate VCS fabric. If you need to change the VCS ID, use the vcs-idx parameter, where x is the new VCS ID number.

vcs rbridgeid 1 vcsid 2 enable

4.Enter the copy running-configstartup-configcommand to apply the currently running configuration, including any changes made, to the startup configuration. You must type in the entire command, there is no autocomplete for it. This is important to capture any changes that have been made to the running configuration so that they will persist the next time the switch reboots in the same mode.

5.Reboot the switch.

When the switch comes back up it will be enabled in VCS mode.

Disabling VCS mode

Perform the following step to disable VCS mode.

1.Log in to the switch using an account that has the admin role.

2.Enter the no vcs enable command. The command removes the current running configuration and resets the switch to the default standalone configuration when it reboots.

The switch reboots when you confirm that you want to disable VCS mode. When the switch comes back up it will be enabled in standalone mode.

Configuring switch ports

By default, the interfaces are not configured as switch ports. In order to put an interface in Layer 2 mode, use the following command in Interface Configuration mode.

switch(conf-if-te-1/0/3)#switchport

To remove an interface from Layer 2 mode, use the following command

switch(conf-if-te-1/0/3)#no switchport

Installing and connecting an SFP+ transceiver

The Brocade VDX 6720 supports only Brocade-branded SFP+ optical or copper transceivers. For its DCB connections, the Brocade VDX 6720 uses SFP+ transceivers that support either optical or Brocade-branded direct attached copper and optical (Laserwire) cables. The optical SFP+ transceivers support both SR (Short Reach) and LR (Long Reach) modules. Direct attached copper cables support distances of 1 meter, 3 meters, and 5 meters. Direct attached optical cables support distances of 10 meters and 20 meters.

To monitor the transceivers, the show media command output shows the transceiver information for all interfaces on the switch. Any unqualified transceiver may be disabled and a log message is generated.

Complete the following steps to install an SFP+.
