Command
Switch(config-cmap)# [no] match access-group
{ acl_index | name acl_name }
Switch (config-cmap)# [no] match ip precedence
ipp_value1 [ ipp_value2 [ ipp_valueN ]]
Switch (config-cmap)# [no] match ip dscp dscp_value1
[ dscp_value2 [ dscp_valueN ]]
Switch (config-cmap)# [no] match any
Switch (config-cmap)# match flow ip {source-address
