Hi Vinay, According to the documentation:
- "set-tos" is used to set the TOS or DSCP field value of packets sent to the client to the value passed in <tos> on platforms which support this. This value represents the whole 8 bits of the IP TOS field, and can be expressed both in decimal or hexadecimal format (prefixed by "0x") It does not expect a log format variable as your trying to do.
