NOTE:

The user-defined flow template you are applying to an interface must already exist.

You can apply only one user-defined flow template on an interface.

The default flow template defines five fields: the source IP address, destination IP address, source port
number, destination port number, and protocol type.

When the length limit for the match criteria in an ACL rule is 18 bytes for an SPE card, available
parameters of the default flow template are sip, dip, ip-protocol, sport, and dport.

When the length limit for the match criteria in an ACL rule is 36 bytes for an SPE card, available
parameters of the default flow template are sip, dip, ip-protocol, sport, dport, icmp-code, icmp-type,
tos, dscp, ip-precedence, mpls-exp, tcp-flag, and fragment.

Configuring an ACL rule length limit mode

The ACL rule length limit mode defines the length of the fields available for an ACL flow template. When

a large number of ACL rules are required on the router, you may need to change this mode.
To configure an ACL rule length limit mode:

Step Command

Remarks

1.

Enter system view.

system-view

N/A

2.

Set the ACL rule
length limit mode.

acl mode { 1 | 2 | 3 | 4 }

The default setting is 2.

NOTE:

The limit mode setting is saved automatically, but it takes effect only after you restart your router.

The limit mode setting does not take effect on an SPE card with an ATM subcard.

The limit mode setting does not take effect for IPv6 ACLs on an SPE card.

When configuring IPv6 ACLs for a QoS policy that is to be applied to an SPC card, you must set the ACL
rule length limit to 80 bytes. For more information about the ACL rule length limit, see

ACL and QoS
