SUMMARY

The Cisco show Mac address-table template appears to fail when there is a line of the Mac address-table that does not have anything in the ports column.

I have verified this on multiple computers running the latest version of the template and it appears to fail every time.

STEPS TO REPRODUCE

import netmiko 

device = ConnectHandler(device_type='cisco_ios', ip=ip, username=username, password=password)
mac_table = device.send_command("show mac address-table", use_textfsm=True)

EXPECTED RESULTS

I hoped to be able to parse the output of show Mac address-table.

ACTUAL RESULTS

State Error raised. Rule Line: 32. Input Line: *  189  0100.5e02.7ffe    static  Yes          -   

[romanstech]

Yes, I have the same issue so I started using show mac address-table dynamic command and it works ok. We don't usr static MAC so it's ok for me.

[mjbear]

This may have been fixed in PR #1006

@hmolles @romanstech
Would you be willing to test on live gear and report back?

Thank you!
