This particular thread isn't the first time I've heard commentary regarding the interface name size in the kernel data structure. I'm not sure what a sensible limit is, but 16 (or 15) seems a little on the small side. Even Cisco has longer names than the Linux limit: echo -n "TenGigabitEthernet1/0/24" | wc -c 24 -m > Samuel > >
