Cisco Catalyst and Supervisory engines

Posted on 2007-10-19

If I go for 4507R vis a vis 4506, I get the same number of line cards(5) but Single SUP support.
Which one is better? My max need ever would suffice by 5x48port line cards.

Also, 4507R & also 4506 models seems to support: [Supervisor Engine II-Plus, II-Plus-10GE , IV, V, V-10GE.]

What should be my basis to choose SUP engine? The vendor in his BOQ has mentioned "Catalyst CAT 4500 Sup II + 10GE".
Is this OK or should I look for some specific SUP engine?

    The only difference between a 4506 and a 4507R is the ability to have redundant supervisor engines. You have the same number of available slots (50) for line/feature cards.

    The primary difference between supervisor engines is performance. The older models are slower and the newer ones are faster.

    Thanks for the replies, warlock and johnston. I will be more specific in my question in order to point out the place I was coming from when I asked this question.

    Having read about two sup engines in particular  Sup II + 10ge and Sup V, i realised that something was odd there:

    I was looking at Cisco Catalyst 4500 Series Supervisor Engine II-Plus-10GE, datasheet here:

    I realised that if I use this on Cat 4506 or 4507R chassis, I'll get a switching fabric of 108Gbps on each.

    On the contrary, Table 2 of the same link above depicts that;

    Layer 2-4 Performance of Supervisor Engine II-Plus-10GE is 108 Gbps AND that of Supervisor Engine V-10GE is 136 Gbps.

    What should I be concerned about? Switching fabric or L2/3 performance?

    Obviously SUP V has higher performance on L2-3 front.

    Now if I browse through;

    I see that;

    Evn though, Supervisor Engine V L2-4 performance is stated to be 96gbps, it's switching fabric support for 4506 Chassis is mere 64 Gbps, and that of 4507R is mere 68 Gbps.

    Much worse for the two Catalyst models than that of Sup II + 10GE.

    Am I missing something here or is my analysis correct? Is Sup V giving worse performance than Sup II plus?

    Accepted Solution

    The Cisco Catalyst 4500 Series Supervisor Engine II-Plus-10GE is optimized for LAN access for medium-sized enterprises, education customers, or small enterprise or branch offices. When customers require enhanced routing capabilities (such as Enhanced Interior Gateway Routing Protocol [EIGRP], Open Shortest Path First [OSPF], Intermediate System-to-Intermediate System [IS-IS], and Border Gateway Protocol [BGP]), NetFlow services, or higher performance and scalability, customers should consider the Cisco Catalyst 4500 Series Supervisor Engine IV, V, or V-10G. These supervisor engines are optimized for the higher-density enterprise LAN, medium-sized enterprise branch-office backbone, or Layer 3 distribution points. The supervisor engines V and V-10GE support additional Ethernet ports for even higher-density applications, scaling up to 136 Gbps. The supervisor engines IV, V, and V-10GE deliver nonblocking Layer 2-4 switching with enhanced Layer 3 and 4 services and routing (EIGRP, OSPF, IS-IS, and BGP) to power-resilient, intelligent multilayer switching solutions for converged data, voice, and video networks
                   They are different in several different ways to include hardware setup and or overall offerings to inclcude higher and nlower core clock speeds between the 2 diff. models. Depending on your network needs, typically L2/3 performance is key along with net availability. Ask you self what you think your network needs as far as performace in this scenario as there is a sizable price diff. between the two but are in direct reflection to the cards cabalility. Some offering basic switching on L2 and L3 and the other offering enhanced during multilayer switching. Among other things such as STP Instance, SVI's, ... so figure your pricing needs along with the boards memory and core speed and throughput and you can form a favorable opinion.

    You're comparing two different classes of product. The sup II has a pair of 10gig ports while the sup V only has 1gig ports. To support the higher traffic, the sup II has been... "improved" so that it's capable handling the traffic.

    Now if you were to compare a similar sup II (with 1 gig ports) to the sup V, you'd see consistent performance numbers.
