Enabling or disabling Layer 2 switching
By default, device supports Layer 2 switching and switches the routing protocols that are not
supported. You can disable Layer 2 switching globally or on individual ports.
NOTE
Make sure you really want to disable all Layer 2 switching operations before actually disabling it.
Consult your reseller or Brocade for information.
To globally disable Layer 2 switching on the device, enter commands such as the following.
BigIron RX(config)# route-only
BigIron RX(config)# exit
BigIron RX# write memory
BigIron RX# reload
To re-enable Layer 2 switching globally, enter the following.
BigIron RX(config)# no route-only
BigIron RX(config)# exit
BigIron RX# write memory
BigIron RX# reload
Syntax: [no] route-only
To disable Layer 2 switching only on a specific interface, go to the Interface configuration level for
that interface, then disable the feature. The following commands show how to disable Layer 2
switching on port 3/2.
BigIron RX(config)# interface ethernet 3/2
BigIron RX(config-if-e10000-3/2)# route-only
Syntax: [no] route-only
To re-enable Layer 2 switching, enter the command with “no”.
BigIron RX(config-if-e10000-3/2)# no route-only
CAM partitioning for the BigIron RX
In releases prior to 02.3.00, CAM partitioning was not configurable. Starting in BigIron RX software
release 02.3.00, you can specify the percentage of CAM assigned to each of the CAM entry types
globally. CAM Partitioning is not required on the device. The default CAM allocations are described
in the following.

simultaneously.
