Tried -k2,2 and it binned loads of old entries which I wanted!
Say I have this data, the highest number (newest) one will always be at the top and I only want to keep the top one as everything right of, and including, column 2 is the same (nothing has changed since last sweep).
1349455502 ygtr-1b:3/1/19 10/100/Gig Ethernet SFP
1349246545 ygtr-1b:3/1/19 10/100/Gig Ethernet SFP
However if we get the following then I want both entries retaining
1349455502 ygtr-1b:3/1/19 10/100/Gig Ethernet SFP
1349246545 ygtr-1b:3/1/19 Old customer name typed in here
-k2,2 seems to ONLY consider column 2 which is no good based on my first post's criteria.
This is tricky!

EX(4) BSD Kernel Interfaces Manual EX(4)
NAME
ex -- driver for 3Com Fast EtherLink XL (3c900, 3c905, 3c980) and similar PCI bus and cardbus Ethernet interfaces
SYNOPSIS
ex* at cardbus? function ?
ex* at pci? dev ? function ?
DESCRIPTION
3Com Ethernet and Fast Ethernet cards supported by the ex driver include:
3c450-TX 10/100 Ethernet
3c555 MiniPCI 10/100 Ethernet
3c575-TX Ethernet
3c575B-TX Ethernet
3c575CT Ethernet
3c656 MiniPCI 10/100 Ethernet
3c656B MiniPCI 10/100 Ethernet
3c656C MiniPCI 10/100 Ethernet
3c900-TPO Ethernet
3c900-COMBO Ethernet
3c900B-TPC Ethernet
3c900B-TPO Ethernet
3c900B-COMBO Ethernet
3c905-T4 10/100 Ethernet
3c905-TX 10/100 Ethernet
3c905B-COMBO 10/100 Ethernet
3c905B-FX 10/100 Ethernet
3c905B-T4 10/100 Ethernet
3c905B-TX 10/100 Ethernet
3c905CX-TX 10/100 Ethernet
3c980 Server Adapter 10/100 Ethernet
3c980C-TXM 10/100 Ethernet
3cSOHO100-TX 10/100 Ethernet
All versions of the EtherLink XL (except the older 3c900 and 3c905) support IPv4/TCP/UDP checksumming in hardware. The ex driver supports
this feature of the chip. See ifconfig(8) for information on how to enable this feature.
MEDIA SELECTION
Some of these network interfaces support the Media Independent Interface (MII), a bus which can have at least one arbitrary Physical inter-
face (PHY) chip on it. NetBSD supports MII and has separate drivers for many different PHY chips, including ukphy(4), a generic PHY driver
that can support many PHY chips that NetBSD does not yet have a specific driver for.
Support for the PHY found on a given NIC must be configured into a NetBSD kernel config(1) for this driver to work properly in those cases.
See ifmedia(4), and mii(4).
