Enabling or disabling layer 2 switching
2
Example : To increase the size of the IP route table
Brocade(config)# system-max ip-route 120000
Brocade(config)# write memory
Brocade(config)# exit
Brocade# reload
NOTE
If you enter a value that is not within the valid range of values, the CLI will display the valid range for
you.
To increase the number of IP subnet interfaces you can configure on each port on a Brocade device
to 64, enter the following commands.
Syntax: [no] system-max ip-subnet-port num
The num parameter specifies the maximum number of subnet addresses per port. The minimum,
maximum and default values for this parameter are described in
Table 9 .
NOTE
You must reload the software for the change to take effect.
Enabling or disabling layer 2 switching
By default, Brocade devices supports routing over layer 2 switching. You can enable layer 2
switching globally or on individual port using the no route-only command.
NOTE
On the Brocade NetIron CES and Brocade NetIron CER, the route-only command should not be
configured on
untagged MPLS uplinks when using it for VPLS or VLL. Otherwise, incoming VPLSor
VLL traffic is dropped.
The no route-only and route-only commands prompts you for whether or not you want to change the
“route-only” behavior. You must enter y if you want to proceed or n if you do not. The prompt is
displayed as shown in the following examples of the no route-only and route-only commands.
NOTE
Always perform a reload after removing a route-only config or enabling route-only. Removing or
enabling the route-only option without a reload will cause multicast issues.
To enable Layer 2 switching globally, enter the following.
Brocade(config)# no route-only
This will change the route-only behavior at the global level.
Are you sure? (enter ‘y’ or ‘n’): y
Global ‘route-only’ committed.
To globally disable Layer 2 switching on a Brocade device and return to the default (route-only)
condition, enter commands such as the following:
Brocade(config)# system-max ip-subnet-port 64
Brocade(config)# write memory
Brocade(config)# exit
Brocade# reload
