Usage guidelines
Execute this command multiple times to add new rules to a DE rule list. Up to 100 rules can be configured
for a DE rule list. Executed once, the undo fr del protocol ip command removes only one DE rule. To
remove a DE rule list, make sure that all the DE rules in the DE rule list are removed.
If you execute this command with no optional parameters specified, the DE rule list is created for all the
IP packets.
Examples
# Add a rule that sets the DE flag bits of all the FR packets encapsulated with IP packets to 1 to DE rule
list 1.
