[c-nsp] Metro Ethernet Switch

"This would be the deciding factor. And if you are planning to deploy

This is no more applicable in your case as you are positioning the 4500 as NPE,
if UPE then a big No. Now its a matter of weighing your specs with the available 
capacities in 4500.
 
As far as the MAC entries for 4500 go, both 4500 and 7600 with SUP720 support 
only 32K Mac. If you have seen soemthing more than 32k MAC, can you give the
reference for the information.
 
Rest all seems fine, finally you shoud consult your local SE regarding the hardware 
performanc vis-a-vis your requirements and future capacity as well.
 
And yes in the past 3 projects we have positioned 7600 as the NPE.
IF you have any more queries please feel free to revert back.
 
HTH-Cheers,
Swaroop

	Hi,
	
	i looked into the Datasheet for the WS-SUP720-3BXL and i found out that the card only support 32K mac-entries.
	This is lower as the 4500 supports, is this a error in the datasheet or do i miss any information? 
	
	
	Thanks markus.

		Hi Markus,
		 
		For what functional purpose you are looking at 4500, as a UPE or NPE.
		This would be the deciding factor. And if you are planning to deploy 
		Triple Play Services, then want you to consider that 4500 doesnt support MVR.
		This is the last I am aware of 4500 from our last poject.
		 
		May be 7609 for NPE would be really good.
		More infor would be appreciated.
		 
		HTH-Cheers,
		Swaroop

			Hi,
			
			any one can suggest a switch for metro ethernet deployment.
			
			my requirements are:
			100 to 200 SFP ports  minimum 2 10 Gig ethernet ports.
			more than 127 spanning-tree instance
			802.1s , 802.1w/d
			more than 64K mac-addresses
			q-in-q
			4095 VLAN ids and active vlans.
			Privat vlan support
			IGMP v2 and V3
			Layer 2 QOS
			
			I have found the c4503 and c4506, but i do not know which supervisor card i
			need to get the above requirements.
			
			Has any one experience with the c4500 series with such a installation?
			Maybe someone has a better suggestion?
			
			
			Thanks Markus
