Table 335: Supported Match Conditions Applicable to IPv4 Traffic for Firewall Filters on J-EX
Series Switches (continued)
Match Condition Description
traffic-class Differentiated Services code point (DSCP).
The DiffServ protocol uses the
type-of-service (ToS) byte in the IP header.
The most significant six bits of this byte form
the DSCP.
You can specify DSCP in hexadecimal,
binary, or decimal form.
In place of the numeric value, you can
specify one of the following text synonyms
(the field values are also listed):
TTL type to match. The value can be 1–255.
ttl value
The VLAN that is associated with the packet.
vlan [vlan-name |

Some of the numeric range and bit-field match conditions allow you to specify a text
synonym. For a list of all the synonyms for a match condition, do any of the following:
If you are using the J-Web Filters Configuration page, select the synonym from the
appropriate list.
If you are using the CLI, type a question mark (
To specify the bit-field value to match, you must enclose the values in quotation marks
( " " ). For example, a match occurs if the RST bit in the TCP flags field is set:
tcp-flags "rst";
