Hi,Dear Sir/Madam,
we config a l2 vpn between two 6509, it worked, but we move line between two 6509 to SDH to extend the distance.
but the sdh device can't allowed <64 bytes packet, we found when <64 bytes packet send from 6509 was dropped by sdh device.
can we config control-word on two 6509 to auto pad packet to 64 bytes?
but we found one 6509 don't have control-word ,the other 6509 has control-word configured, but two 6509 can't negotiate control-word?
can i auto padding to 64 bytes by using control-word?
