2. Run the route-only command to disable switching and enable routing on the LAG.
Brocade(config-if-e1000-4/1/4)# route-only
3. Run the ip address command to assign an IP address for the LAG.
Brocade(config-if-e1000-4/1/4)# ip address 25.0.0.2/24
The following example shows the creation and deployment of a dynamic LAG that is used for routing on a FastIron device with Layer 3
image.
Brocade(config)# lag “brocade-LAG” dynamic id 55
Brocade(config-lag- brocade-LAG)# ports ethernet 1/1/1 ethernet 2/1/3 ethernet 3/1/4 ethernet 4/1/4
Brocade(config-lag- brocade-LAG)# primary-port 4/1/4
Brocade(config-lag- brocade-LAG)# deploy
Brocade(config-lag- brocade-LAG)# exit
Brocade(config)# interface ethernet 4/1/4
Brocade(config-if-e1000-4/1/4)# route-only
Brocade(config-if-e1000-4/1/4)# ip address 25.0.0.2/24
Disabling IP checksum check
The disable-hw-ip-checksum-check command traps a packet with bad checksum to the CPU. Previously, if the packet processor
detected a packet with, for example, the checksum 0xFFFF, it would treat it as a bad checksum even if it was correct and it would drop
the packet. Now, the command
disable-hw-ip-checksum-check traps the packet at the CPU and if the checksum is correct, it forwards
the packet.
To set disable hardware ip checksum check for all ports, enter the following command.
device# disable-hw-ip-checksum-check
disable-ip-header-check set for all ports
To clear disable hardware ip checksum check on all ports, enter the following command.
device# no disable-hw-ip-checksum-check ethernet 13
disable-hw-ip-checksum-check cleared for ports the 13 to 24
To set disable hardware ip checksum check on for example, port range 0-12, enter the following command.
device# disable-hw-ip-checksum-check ethernet 2
disable-ip-header-check set for ports ethe 1 to 12
To set disable hardware ip checksum check on, for example, port range 13-24, enter the following command.
device# disable-hw-ip-checksum-check ethernet 22
disable-ip-header-check set for ports ethe 13 to 24
To clear disable hardware ip checksum check on, for example, port range 13-24, enter the following command.
device# no disable-hw-ip-checksum-check ethernet 13
disable-hw-ip-checksum-check cleared for ports the 13 to 24
NOTE
The port range could be any consecutive range, it may not necessarily be a decimal number.
Syntax: [no] disable-hw-ip-checksum-check ethernet portnum
NOTE
This command only functions on the IPv4 platform.
