below is the sql program. i do not know much about sql. i want to exclude from the report interfaces with a description ME-Cyta. can you help?

thanks

SELECT
n.nodeid,
i.interfaceid,
n.Caption as Node,
i.Caption as Interface,
MAX(t.In_Averagebps) AS 'MAX_IN',
MAX(t.Out_Averagebps) AS 'MAX_OUT',
AVG(t.In_Averagebps) AS 'AVG_IN',
AVG(t.Out_Averagebps) AS 'AVG_OUT',
i.InterfaceSpeed,
ROUND(AVG(t.In_Averagebps)/InterfaceSpeed*100,2) AS 'AVGPercent_Used_IN',
ROUND(AVG(t.Out_Averagebps)/InterfaceSpeed*100,2) AS 'AVGPercent_Used_OUT'

FROM
(Nodes n JOIN Interfaces i ON (n.NodeID = i.NodeID)) JOIN InterfaceTraffic t ON (i.InterfaceID = t.InterfaceID)

WHERE
(
  (
 (
    n.MachineType like 'Cisco [1-7]%'
and not i.Caption   like '%cellular%'
and not i.Caption   like '%gigabitethernet0/1.2%'

   )

  )
AND
   (
   LTRIM(MONTH(t.DateTime)) = (LTRIM(MONTH(getdate())) -1)
   AND
   DATEPART(dw, t.DateTime) between 2 and 6
   AND
 (
  t.DateTime BETWEEN
   CAST(Convert(Char(10), t.DateTime, 101) as smalldatetime) + ' 08:00'
   AND
   CAST(Convert(Char(10), t.DateTime, 101) as smalldatetime) + ' 15:00'
 )
   )
)

Group By n.caption, n.nodeid, i.interfaceid, i.caption, i.InterfaceSpeed

ORDER BY n.caption, avg_in Desc
