31.3.4 Configure Packet Modify Rule
Syntax [no] modify [pos ] [passive]
[match [in ] [out ]
[src ] [dst ]
[proto ] [dport ] ]
set dscp [adjust-prio]
Context Firewall Configuration context
Usage Add or delete a modify rule to change the DSCP bits in the IP header for
routed traffic.
❼ Rule maintenance parameters (insert position, activate/deactivate or
delete rule):
– Modifier rules are inserted and evaluated in order. The ”pos ”
parameter controls at what position in the rule order this modify rule
should be inserted, or when it comes to removing a rule, which rule
to remove. The order is kept compact (see ”Delete rule” below).
Use the ”show modify” command to list the current modifier rule
list and their position numbers. Examples:
✯ Insert rule: Use, e.g., ”modify pos 4 match in vlan2 set dscp
30” will insert a modifier rule at position 4 in the list of modifier
rules. The rule previously at position 4 will now have position 5,
and so on.
If no position argument is given, the modifier rule will be inserted
last in the list. The position of a command can be modified using
the ”move” command (see
section 31.3.10 ).
✯ Delete rule: Use, e.g., ”no modify pos 5” to delete the modi-
fier rule at position 5 from the list of modifier rules. The rule pre-
viously at position 6 will now have position 5, and so on, keeping
the list compact.
A rule can also be deleted by using the no-form, e.g., the rule
”modify match in vlan1 out vlan2 set dscp 0” can be deleted
by the command ”no modify match in vlan1 out vlan2 set
dscp 0”.
– The ”passive” parameter specify that this rule is created as in-
active. It will be shown in config but not used. To enable use
”passive” command, see
section 31.3.11 .
