HP A8800 Series Command Reference Manual page 51

If this command is executed multiple times in a class, the new configuration does not overwrite
the previous one. When such a command is configured, the IP precedence values are arranged
automatically in ascending order.
You can configure up to eight IP precedence values in one command line. If the same IP
precedence is specified multiple times, the system considers them as one. The relationship
between different IP precedence values is OR. If a packet matches one of the defined IP
precedence values, it is considered as matching the if-match clause.
To delete a criterion matching IP precedence values, the specified IP precedence values in the
command must be identical with those defined in the criterion (sequence may be different).
8. Defining a criterion to match customer network VLAN IDs or service provider network VLAN IDs
If this command is executed multiple times in a class, the new configuration does not overwrite
the previous one. After such a command is configured, all the VLAN IDs are arranged in
ascending order automatically.
You can configure multiple VLAN IDs in one command line. If the same VLAN ID is specified
multiple times, the system considers them as one. The relationship between different VLAN IDs
is logical OR. If a packet matches one of the defined VLAN IDs, it is considered as matching the
if-match clause.
To delete a criterion matching VLAN IDs, the specified VLAN IDs in the command must be
identical with those defined in the criterion (sequence may be different).
9. Defining a criterion to match MPLS EXP values
You can configure multiple MPLS EXP match criteria for a class. The defined MPLS EXP values
are automatically arranged in ascending order.
You can configure up to eight MPLS EXP values in one command line. If the same MPLS EXP
value is specified multiple times, the system considers them as one. If a packet matches one of
the defined MPLS EXP values, it matches the if-match clause.
To delete a criterion that matches MPLS EXP values, the specified MPLS EXP values in the
command must be identical with those defined in the criterion (the sequence may be different).
The MPLS EXP field exists only in MPLS packets, so this match criterion takes effect for only the
MPLS packets.
10. Defining a criterion to match MPLS labels
You can configure multiple MPLS label match criteria for a class. The defined MPLS labels are
automatically arranged in ascending order.
You may configure multiple MPLS label values in one command. If the same MPLS label value
is specified multiple times, the system considers them as one. If a packet matches one of the
defined MPLS label values, it matches the if-match clause.
To delete a criterion that matches MPLS label values, the specified MPLS label values in the
command must be identical with those defined in the criterion (the sequence may be different).
