Disabling or re-enabling a port
1
Brocade(config)# interface e 1/8
Brocade(config-if-e10000-1/8)# auto
Brocade(config-if-e10000-1/8)# link-config gig copper autoneg-control down-shift
Syntax: [no] link-config gig copper autoneg-control [down-shift|100m|10m]
The 10m option will limit the port to negotiation to speeds and duplex of 10mb.
The 100m option will limit the port to negotiation of speeds and duplex below 100mb.
Disabling or re-enabling a port
The port can be made inactive (disable) or active (enable) by selecting the appropriate status
option. he default value for a port is disabled.
To disable port 8 on module 1 of a Brocade device, enter the following command.
Brocade(config)# interface e 1/8
Brocade(config-if-e10000-1/8)# disable
Syntax: [no] disable
Syntax: [no] enable
You also can disable or re-enable a virtual routing interface. To do so, enter commands such as the
following.
Brocade(config)# interface ve 1
Brocade(config-vif-1)# disable
Syntax: [no] disable
To re-enable a virtual routing interface, enter the enable command at the Interface configuration
level. For example, to re-enable virtual routing interface v1, enter the following command.
Brocade(config-vif-1)# enable
Syntax: [no] enable
Disabling Source Address Learning on a port
The default operation is for Source Address (SA) Learning to be enabled on all ports. It can be
useful to disable SA Learning on a port in situations where high CPU usage is occurring because a
large number of packets are being sent to the CPU for SA Learning. For example, it can be useful to
disable SA Learning on physical ports that are part of a Virtual Ethernet (VE) interface that has no
need to switch packets.
SA Learning can be disabled on a port using the sa-learning-disable command as shown in the
following.
Brocade(config)# interface e 1/8
Brocade(config-if-e10000-1/8)# sa-learning-disable
Syntax: [no] sa-learning-disable
