How to collect Base Ethernet MAC address from Cisco devices

We need to collect Base Ethernet MAC address from Cisco devices for LLDP use.  I found LLDP ChassisID OID, but some devices respond in Hex and Orion's UNDP poller doesn't seem to handle Hex very well.

The information is also present via show version.  I see that the Cisco IOS device templates contain s show version definition.  But I haven't been able to figure out how to get Orion to gather the show version data.  Does anyone have any suggestions/ideas on how to gather Base Ethernet Mac address on Cisco devices, other than creating a new config type?
