Configuring interfaces to support VLANs
This section details the various tasks required to configure and manage VLAN traffic.
Enabling and disabling an interface port
NOTE
DCB interfaces are disabled by default in standalone mode, but enabled by default in Brocade
VCS Fabric mode.
NOTE
DCB interfaces do not support auto-negotiation of Ethernet link speeds. The DCB interfaces support
10-gigabit Ethernet and 1-gigabit Ethernet.
To enable and disable an interface port, perform the following steps from privileged EXEC mode.
1. Enter the configure terminal command to access global configuration mode.
2. Enter the interface command to specify the DCB interface type and slot/port number.
The gigabitethernet rbridge-id/slot/port operand is used only for Brocade VDX 6710, Brocade
VDX 8770-4, and Brocade VDX 8770-8 switches in VCS mode. The prompt for these ports has the
format: switch(config-if-gi-22/0/1)# .
switch(config)# interface tengigabitethernet 0/1
Configuring the MTU on an interface port
NOTE
The entire fabric acts like a single switch. Therefore, MTU is applicable only on the edge-ports, and
not on ISL.
To configure the maximum transmission unit (MTU) on an interface port, perform the following steps
from privileged EXEC mode.
