Class Maps Table—Lists globally defined class maps on the device.
Class Map Name—Unique identifier of a class map on the managed device.
–
Type—Indicates whether the class map can be used on Ethernet interfaces or not. The C65/76M
EMS will discover class maps that are not suitable for use with Ethernet interfaces, however you
cannot add, remove, or configure these class maps. They are listed in the table only to indicate that
the class map names are in use. This attribute has one of the following values:
– ethernet—The class map can be used on Ethernet interfaces.
other—Indicates that a class map contains more than one match entry or it contains a match
–
criteria that is unsupported on Ethernet interfaces.
empty—Indicates a class map with no match entries. An empty class map cannot be applied to
–
an Ethernet interface, however you may modify it.
Match Condition—Specifies whether to match all criteria in the class map or any criteria in the list.
Match IP Precedence—Specifies IP Precedence values to match. Up to eight values may be
specified. If no values are specified, IP Precedence matching criteria is disabled. This attribute may
only have a value if the Type attribute is ethernet (1) and both Match DSCP and Match ACL
attributes are nil.
Match DSCP—Specifies DSCP values to match. Up to eight values may be specified. If no values
are specified, DSCP matching criteria is disabled. This attribute may only have a value if the Type
attribute is ethernet and both Match IP Precedence and Match ACL attributes are nil.
Match ACL—Identifier of a named or numbered (standard or extended) ACL. In no identifier is
specified, the ACL matching criteria is disabled. The named or numbered ACL must be configured
on the device before this class map can be associated with an interface. The device will not detect
an invalid class map until you associate the class map with an Ethernet interface. This attribute may
only have a value if the Type attribute is ethernet and both Match IP Precedence and Match DSCP
attributes are nil.
Add Class Map—Launches the QoS Management—Add Class Map window to create a class map
on the managed device.
