Configuring IP parameters

Brocade(config)# trunk e 3/1 to 3/4
trunk transaction done.
Brocade(config-trunk-3/1-3/4)# exit
Brocade(config)# interface ethernet 3/1
Brocade(config-if-e1000-3/1)# ignore-options
If the LAG is removed, the ignore-options command will be propagated to all ports that were
previously in the LAG.
If you try to create a LAG where some of the ports have the ignore-options command configured
and some do not, the LAG will not be allowed as shown in the following example.
Brocade(config)# trunk e 3/1 to 3/2
port 3/1 ignore-options is Enabled, but port 3/2 ignore-options is Disabled
Error: port 3/1 and port 3/2 have different configurations
trunk transaction failed: trunk Config Vetoed
Configuring the ignore-options command on a LACP LAG
Just as with static LAGs, if you want to configure the ignore-options command on an LACP LAG, the
command must be enabled on all ports within the LAG. If it is not, the LACP LAG will not be
accepted as shown in the following.
Brocade(config)#lag sta_lag static
Brocade(config-lag-sta_lag)#ports e 1/3 to 1/4
Brocade(config-lag-sta_lag)#primary-port 1/3
Brocade(config-lag-sta_lag)#deploy
Brocade(config-lag-sta_lag)#int e 1/3
Brocade(config-if-e1000-1/3)#ignore-options
Brocade(config)#lag sta_lag static
Brocade(config-lag-sta_lag)#ports e 1/3 e 1/4
Brocade(config-lag-sta_lag)#primary-port 1/3
Brocade(config-lag-sta_lag)#deploy
port 1/3 ignore-options is Enabled, but port 1/4 ignore-options is Disabled
Error: port 1/3 and port 1/4 have different configurations
LAG sta_lag deployment failed!
Brocade(config)#int e 1/3
Brocade(config-if-e1000-1/3)#ignore-options
Brocade(config-if-e1000-1/3)#lag dyn_lag dynamic
Brocade(config-lag-dyn_lag)#ports e 1/3 e 1/4
Brocade(config-lag-dyn_lag)#primary-port 1/3
Brocade(config-lag-dyn_lag)#deploy
port 1/3 ignore-options is Enabled, but port 1/4 ignore-options is Disabled
Error: port 1/3 and port 1/4 have different configurations
LAG dyn_lag deployment failed!
Configuring domain name server (DNS) resolver
The DNS resolver lets you use a host name to perform Telnet, ping, and traceroute commands. You
can also define a DNS domain on a Brocade device and thereby recognize all hosts within that
domain. After you define a domain name, the Brocade device automatically appends the
appropriate domain to the host and forwards it to the domain name server.
