Would it help to be more explicit in your linkloop invocation by specifying the PPA?
e.g.
linkloop -i loacl_nic_ppa linked_nic_mac_addr

[Joseph Loo · Accepted solution]

hi,

try this though without the -i option it should take the first PPA (in your case 0):

# linkloop -i 0 0x001083F92F56
using lan0 to test lan1

# linkloop -i 1 0x001083F92F55
using lan1 to test lan0

if both fails, there may be some problem with the cable.

regards.

Lugy,
linkloop is failing because it is a mac address level of connectivity check and since you are not specifying any options, we dont know how the box is trying to get to this mac address
Try this and it should come back OK

linkloop -i 1 0x001083F92F56

thanks
