Apr 09, 2012traceroute over a VLAN
I know I can use tcpdump -i VLAN_name and only see traffic on that VLAN. The MAN page for traceroute reference a -i option as the interface used to send packets, but I get the following error when I try to use traceroute -i internal_vlan_87 172.31.87.5.
setsockopt SO_BINDTODEVICE: No such device
Any help/guidance would be greatly appreciated.

Mm... You may want to keep your vlan names shorter than 16 characters... That was an old one from way back 9.0.3 IIRC...
