Assigning Static MAC Addresses
If you use static mac-address assignments on every switch port, I hope you like to type a lot.
If you do, Table 5.6 shows you how to do it:
TABLE 5 . 6
Command and Meaning
Command Meaning
static
Sets a static MAC address on a switch interface
You can set a static MAC address in the MAC address table, but like setting static
MAC port security, it’s a ton of work. But in case you want to do it, here’s how it’s done:
S1#config t
S1(config)#mac-address-table static aaaa.bbbb.cccc vlan 1 int fa0/5
S1(config)#do show mac address-table
Mac Address Table

1 0050.0f02.642a DYNAMIC Fa0/3
1 aaaa.bbbb.cccc STATIC Fa0/5
Total Mac Addresses for this criterion: 31
S1(config)#
Here you can see that a static MAC address is now assigned permanently to interface fa0/5
and that it’s also assigned to VLAN 1 only.
