Configuring the InterfaceHere's an example to correspond with our previously demonstrated motd:Switch#conf tSwitch(config)#banner motd $Enter TEXT message, End with the character '$'.Warning: All changes to this switch must be preapproved by theDirector of Network Engineering. Termination may result ifthis warning is unheeded.$Switch(config)#I chose the “$” character as my delimiting character. You could just as easilychoose “#” or “.” or even the letter “C.” The trick is to not choose a characterthat you really need in the message. My message didn't have any “$” in it, sothat was a safe character to use.To remove the banner, employ the “no” rule:Switch#conf tSwitch(config)#no banner motdConfiguring the InterfaceEvery interface on a switch has its own configuration. You can specify speed,duplex, an interface name, and, if you're running Base Layer-3 or Full Routercode, you can even specify an IP address. To configure an interface, you mustbe in interface configuration mode:Switch#conf tSwitch(config)#interface e 1Switch(config-if-e1000-1)#Notice that the prompt has changed. You're still in config mode, and nowyou're in a sub-config mode: interface config mode. The “if” in the prompt tellsyou that you're in interface config mode. The “e1000” tells you that you're configuringa gigabit Ethernet port. Finally, the prompt tells you which interfaceyou're configuring (“1,” in this example).Here's an example of how you might use this mode:Switch(config-if-e1000-1)#speed-duplex 100-fullSwitch(config-if-e1000-1)#interface e 5Switch(config-if-e1000-5)#port-name MailServerSwitch(config-if-e1000-5)#Notice that you've forced the speed and duplex of interface 1 to be 100 MbpsFull Duplex. The port is capable of doing gigabit full-duplex, but it's possiblethat you may be dealing with a device that may not negotiate properly. Interface1 is now no longer autonegotiating. Any device plugged into this port mustbe set to 100 Mbps Full Duplex.The next thing you need to do is to change to interface e 5. Now you're configuringa port-name to e 5. Call it “MailServer.” This would presume that youhave a mail server plugged into e 5, but that's up to you.Brocade IP Primer 135
