<strong>Cisco</strong> 1900 IOS Configuration Commands 589 port, which means that unless you specifically configure a hardware address to a switch port, it won’t work. Administrators can also create static entries in the switch; these entries actually create a path for a source hardware address. This can be really restrictive, and you need to be careful when setting static entries because you can basically shut your switch down if you do not plan the configuration carefully. Setting Permanent MAC Address Entries You can configure a permanent MAC address to a switch port by using the global configuration command mac-address-table permanent [macaddress] [interface]. In the example below, the options are as follows: Aging-time This can be used to change the age a MAC address is allowed to stay in the filter table before being cleared. Permanent This sets a permanent address to an interface. If the user changes the host NIC card, then the host will not work until you change the permanent entry address. Restricted This is used with the static command to set a path for source hardware addresses. Very restrictive for where a host can send a frame. To configure a permanent hardware address to an interface, use the command mac-address-table permanent from global configuration mode, as shown below: Todd1900EN#config t Enter configuration commands, one per line. End with CNTL/Z Todd1900EN(config)#mac-address-table ? aging-time Aging time of dynamic addresses permanent Configure a permanent address restricted Configure a restricted static address After you choose the mac-address-table permanent command, add the hardware address and the interface it is associated with. This will restrict the interface to only accept frames from this source hardware address. Todd1900EN(config)#mac-address-table permanent ? H.H.H 48 bit hardware address Todd1900EN(config)#mac-address-table permanent 00A0.2448.60A5 e0/4
590 Appendix B � Configuring the Catalyst 1900 Switch Once you have configured the entry, you can verify this entry by using the show mac-address-table command. Todd1900EN#sh mac-address-table Number of permanent addresses : 1 Number of restricted static addresses : 0 Number of dynamic addresses : 3 Address Dest Interface Type Source Interface List 00A0.2448.60A5 Ethernet 0/4 Permanent All 00A0.246E.0FA8 Ethernet 0/2 Dynamic All 0000.8147.4E11 Ethernet 0/5 Dynamic All 0000.8610.C16F Ethernet 0/1 Dynamic All Todd1900EN# In the switch output above, notice that interface 4 now has a permanent entry with hardware address 00A0.2448.60A5. No other device can connect into interface 4 without updating the permanent entry in the MAC filter table. Setting Static MAC Address Entries You can take this security thing one step further. You can now tell a source interface that it is only allowed to send frames out of a defined interface. You do this with the restricted static command. Seems that it could cause some real havoc at work; you may only want to use this command on your friends if it is a slow day at work. That’ll liven things up a bit. The command mac-address-table restricted static is looking for two options: The first one is the hardware address of the destination interface. The second option will be the source interface that is allowed to communicate with this destination interface. After entering the command mac-address-table restricted static from global configuration mode, enter the hardware address of the destination device: Todd1900EN(config)#mac-address-table restricted static ? H.H.H 48 bit hardware address Todd1900EN(config)#mac-address-table restricted static 00A0.246E.0FA8 ?
