Unable to ping by source interface

I'm having an issue using the -I (source_interface) option on the ping command on S-Series code version 8.11(.04.0005). I checked that the vlan.0.92 interface is up, but it is not allowing me to send the echo request.

Router(su)->ping -I vlan.0.92 192.168.19.82
PING 192.168.19.82 (192.168.19.82) 64 bytes of data.
ping: Could not send echo request
Router(su)->ping -I vlan.0.92 -S 10.155.92.1 192.168.19.82
PING 192.168.19.82 (192.168.19.82) from 10.155.92.1 64 bytes of data.
ping: Could not send echo request

Unfortunately, I cannot do the ping unless I'm sourcing it from VLAN 92 because of the restrictions on the remote device. Certainly I can get on a device contained in VLAN 92 and ping from there, but I think I should be able to do this from the router itself.

What am I missing?

I have just tried it here on an S8 with 08.11.04.0006. It looks like if you use the -I option, you can only ping a remote host that is in the same subnet. However, using the -S option without the -I option seems to work.

Hi Chris, Did Patrick's suggestions work for you?
