cisco 4500 switches and sup

Answered Question
Dec 9th, 2008

hi every body!

I have few questions about the supervisory engines for cisco 4500 series switches. Please refer to the link at end of the post.

for example, the link describes:

sup iv--- entry-level 2/3/4 switching and services.

What does entry level mean here?

sup 6e -- full layer 2/3/4

What does full mean here?

sup 11-plus-10GE -- basics layer

2/3/4

What does basic mean here?

thanks a lot!

I have this problem too.

Entry level often means either there are variants of the same model, and this is the least expensive variant (much like automobile trim levels), or there's a newer variant and the entry level was the best to be had two or more years ago. ;)

Cost is usually the most noticeable difference, since the entry level model has either less performance and/or less features. However, the cost is not always directly related to proportional performance even if features are the same.

Don't get hung up with marketing speak, but carefully compare datasheets to your needs. If we return to my analogy of automobiles, an entry model might not have A/C but the deluxe version does. Importance of this particular distinction, to you, might be whether you live in Florida or Alaska. Likewise, how you might use a 4500 might be more important than whether it's entry level or not.

It's to do with the supervisor switching performance. If you have look at the 4500 Matrix you will see that the SupIV supports 64 Gbps/ 48Mpps of throughput and is designed for small core/medium density access-layer.

check this link, basic means Cisco IOS Software for Cisco Catalyst 4500 Series Supervisor Engine II-Plus and IV; basic Layer 3 software image (RIP, static routes, IPX, AppleTalk)

http://www.cisco.com/en/US/prod/collateral/switches/ps5718/ps4324/product_data_sheet0900aecd80356bde.html

whereas full layer i think is enhanced layer which supports Enhanced Layer 3 software image (OSPF, EIGRP, and IS-IS

thanks for your reply. So the supervisor engine is called basic ,based on cisco ios and layer 3 protocols, it can support.

Entry designation is based on throughput.

Am I correct?
