Finding MAC address with OUI List

Question

I'm in the process of labeling the interfaces of my Cisco 3750G with descriptions referencing the device type that is associated with that port.

I understand that I am able to run a show mac address-table | i 0010 , which will find the interface associated with that mac address as shown below

3750G#show mac address-table | i 0010
 All                      STATIC      CPU
   1    0010.xxxx.xxxx    DYNAMIC     Gi1/0/7
   1    0010.xxxx.xxxx    DYNAMIC     Gi2/0/10
   1    0010.xxxx.xxxx    DYNAMIC     Gi5/0/27
   1    0010.xxxx.xxxx    DYNAMIC     Gi3/0/20

Since manufacturers can have multiple OUI's, is there a way to run that list of possible OUIs with just one command instead of having to copy and paste, changing the variable after the | include every time?

Answer 1

While searching, I found that you're able to pipe multiple variables within the same single command.

For example, if I look for the OUIs of the MAC addresses with a prefix of 0010, 33ca, and 8819 I can use the following command to filter out just those mac addresses with the matching prefixes.

MAC addresses UAA omitted for security

3750G#show mac address-table | i 0010|38ca|8819
   1    0010.xxxx.xxxx     DYNAMIC     Gi2/0/3
   1    38ca.xxxx.xxxx     DYNAMIC     Gi4/0/13
   1    8819.xxxx.xxxx     DYNAMIC     Gi4/0/13
   1    8819.xxxx.xxxx     DYNAMIC     Gi4/0/13
   2    0010.xxxx.xxxx     DYNAMIC     Gi1/0/20
