Table 1-64 Replace_TOS Field Rewriting

Set Content
Replace_tos<New Tos>
Example
1. Set the condition to permit (relay) FTP from the transmit source in filter list
number 1 to the destination with these options:
Operation type:
Upper rank protocol number: 6 (TCP)
Transmit source IP address: 123.123.1.1-123.123.1.123
Destination IP address: 123.123.2.1
Transmit source high-rank protocol port number: 20-21(
Method of checking synchronization of IP address and upper rank protocol port
number:
1-120
Set the IP addresses below.
Class A: 1.0.0.1 to 126.255.255.254
Class B: 128.1.0.1 to 191.254.255.254
Class C: 192.0.1.1 to 233.255.254.254
IP address (127.0.0.0 to 127.255.255.255), and IP address of
class D (224.0.0.0 to 239.255.255.255)
A broadcast address (in which net ID or host ID is all "1" or all
"0" in binary) cannot be set.
Specifies policy group name defined by policy-group
information. When relaying packet that matches the filter
condition, sends the packet to the most priority path in the
output destination registered in policy group specified by this
option. Policy group as the filter condition of receiving side by
specifying -in (Inbound) when setting filter interface
information. (See Subsection 1.1.13 filter interface for details.)
Undefined (Invalidates policy routing function.)
Policy group name specified by policy-group information.
Enables the TOS rewriting function and Diff-serv DS field
rewriting function by specifying a new TOS in decimal. In the
latter case, the high-order 6 bits of the new TOS are used and
the low-order two bits are ignored. Table 1-64 summarizes
how this option works. See Subsection 1.2.7 for further
information.
No TOS rewriting (TOS-QoS conversion table is retrieved with
the TOS of the received packet.)
