Hello,
I also triedand I gotthe same error :
{primary:node0}[edit forwarding-options packet-capture file]
SRX01# set filename /var/tmp/nfs/20160208_capture_flow_reth0 files 10 size 1024000
error: filename: '/var/tmp/nfs/20160208_capture_flow_reth0': Must not contain '/', '%', '.' or a space
error: syntax error, expecting [Enter]: files
{primary:node0}[edit forwarding-options packet-capture file]
SRX01# But as "/var/tmp" is a default parameter, I wondered if it was not possible to change it by order ?
Thanks,
Julien
