616 Appendix B � Configuring the Catalyst 1900 Switch
14. Type show mac-address-table, and notice the permanent entry for
interface e0/9.
15. Use the mac-address-table restricted static global configuration
command to associate a restricted static address with a particular
switched-port interface:
Config t
Mac-address-table restricted static 083c.0000.0002
e0/3 e0/4
The above command only allows traffic to the restricted static address
083c.0000.0002 on interface e0/3 from interface e0/4.
16. Go to interface e0/1 and use the port secure max-mac-count 1
command to enable addressing security and allow only one MAC
address in the filter table on that port. By default, up to 132
MAC addresses can be associated with a single port. By using this
command, we will allow only one workstation.
Config t
Int e0/1
Port secure max-mac-count 1
17. Verify which ports have port security on them by typing show macaddress-table
security. Notice that port e0/1 security is enabled.
Lab B.3: Creating VLANs
In this lab, you will create multiple VLANs on only one switch. Lab B.4 will
have you create VTP configurations that will allow this VLAN information
to be propagated to the second switch.
1. Telnet or connect to the first 1900 switch. Set the hostname of the
switch to 1900A.
#config t
(config)#hostname 1900A
1900A#
