Mala

Firstly, thank you for hosting this session.

With the new sup7-E and the greater throughput available ie. up to 48Gbps per slot with the right linecards/chassis this switch could now be seriously considered as a collapsed core/distro switch in a medium sized campus. Are there any plans to support something like MEC/VSS/VPC on the new supervisor as this would be very useful and would allow for greater flexibility in L2/L3 design.

Re: ASK THE EXPERT - NEW CATALYST 4500E

Hi Jon,

You're right - we do position the Catalyst 4500 as a Price-Performance Campus Distribution.

I am happy to share Catalyst 4500 Roadmap items if you have an NDA - please contact me through your Cisco account team/ Partner.

Thanks,

Mala

Re: ASK THE EXPERT - NEW CATALYST 4500E

Hello Mala,

https://supportforums.cisco.com/thread/2046606?tstart=0

would you confirm that with sup7 all slots of 4510RE can run at 48gbps, and the limitation of sup6 "6 Gbps only on slots 8-10" is lifted?

Please comment the stability issue.

"would you recommend going for sup7 at all? My key factor is stability, not performance. Is the sup7 with IOS15 as stable as sup6 with IOS12?"

Do you plan to add server load balancing feature to 4500 line with sup7?

As of today, our cisco dealer offers sup6 and sup7 at the same price, will it be always like that, or you'll differentiate soon?

thanks,

-igor

Re: ASK THE EXPERT - NEW CATALYST 4500E

With Sup7E and the new 4510R+E chassis, you can run all slots at 48G/ slot

Would definitely recommend Sup7E. We have found Sup7E to be stable in our internal testing.  No immediate plan to add SLB on Sup7E.

Would also recommend going with Sup7E since its newer and has significant advantages (Performance, Netflow, IOS-XE, PoEP and 10G scale to name a few) at the same price as Sup6E. No immediate plan to change price.

Thanks,

Mala

Re: ASK THE EXPERT - NEW CATALYST 4500E

Hi Mala,

Just want to confirm that the Sup7 is 48Gbps full duplex or half duplex?

New Member

Re: ASK THE EXPERT - NEW CATALYST 4500E

Full Duplex and 48G/ slot each way.

Thanks,

Mala

Re: ASK THE EXPERT - NEW CATALYST 4500E

Hello Mala

How is the backplane organization now?

8 Channels with 6 Gbps per slot?

(In such words use the Sup6E 8 Channels with 3Gbps per slot) 

How is he behavior of the 10Ge interface of the WS-X4712-SFP+E ?

How is the influence of the mapping from the backplane channels to the 10GE Ports?

Do we have fix clocking between ports and backplane channels?

Can 1 of 12 10GE ports send wire speed 10 Gigabit stream?

Can 1 of 12 10GE ports receive wire speed 10 Gigabit stream?

Can 4 of 12 10GE ports send simultaneous wire speed 10 Gigabit stream?

Can 4 of 12 10GE ports receive simultaneous wire speed 10 Gigabit stream?

How is the reaction if all 12 10GE ports receive simultaneous wire speed 10 Gigabit stream?

Do we have groups of ports as on 4606 (with 2 groups of 3 ports) line card?

In a configuration with two redundant supervisors 7E in one chassis can 4 of 8 10GE uplink ports be active.

Is it possible to use all 8 10GE Uplinks with oversubscriptions?

What are about supervisors 7E and VSS?

What are about TrustSec in 4500Eplus?

Thanks

Re: ASK THE EXPERT - NEW CATALYST 4500E

Hi,

With the new Sup7E you get

1). 48G/ slot on chassis 4503E, 4506E 4507R+E and 4510R+E

2). 24G/ slot on all slots of 4507R-E and 4510R-E

Only 4 uplinks are active in a redundant configuration (2+2 and non-blocking)

For the 4712 Linecard -

1). It is 2.5:1 oversubscribed since it has a 48G connection to the backplane

2). Ports are organized into 4 groups. By using only 1 port as 10G in each group, you can get 4 port non-blocking (1:1) 10G with 8 ports of non-blocking 1G

For 4606 Linecard -

1). It is 2.5:1 oversubscribed since it has a 24G connection to the backplane

2). Ports are organized into 2 groups. By using only 1 port as 10G in each group, you can get 2 port non-blocking (1:1) 10G with 4 ports of non-blocking 1G

VSS and TrustSec are on the roadmap with Sup7E. Please contact your account team for roadmap details under NDA.

Hope I answered all your Qs. Please feel free to post a follow up.

Thanks,

Mala

wvc210 remote access problem ?

Hi i have sorted the wireless problem and it works fine after such a long time searching around, Can someone please tell me how to access the camera through a web page i can do that by typing the http://(cameras ip address):(cameras port number) and it works fine but thats from my pc when i have asked people to view it it dont work for some reason not sure why ? i think it might only work from my pc as my pc and the camera share the same internet access but when someone else try it from another location it dont work can someone please tell me what am i doing wrong here o what's missing ?

Thank You

Re: ASK THE EXPERT - NEW CATALYST 4500E

I saw that the price of the sup7e and the 6e are the same. Does the sup6e is going to be discontinued? Any specific reason to buy the 6e? Are the sup7e compatible with old 4500 chassis?

Re: ASK THE EXPERT - NEW CATALYST 4500E

Hi Mala,

Please advice, Do we have IOS that is VTP V3 Capable on 4510R Switch.

Re: ASK THE EXPERT - NEW CATALYST 4500E

I would like to know what is required to attach a power over ethernet wireless access points to a Cisco 4500E switch. Is it as simple as connecting a ethernet cable between the wireless access point and the Cisco 4500E switch? Or do we need to purchase additional power over ethernet equipment to install on our rack? I am looking to purchase a Linksys Wireless-N Access Point with Dual-Band WAP610N access point. Is this access point compatible with Cisco's 4500E switch?

Error - Standby console disabled on new Sup 6E for 4500

I got 2 fiber connected to two core from this 4500 with two SUP. I am trying to console to standby sup and it says standby console disabled.

Thanks in advance

Re: ASK THE EXPERT - NEW CATALYST 4500E

Hi,

I would like to know if there is any planned increase in the maximum number of supported etherchannels (currently 64) with sup7-e.

Also, would you recommend sup7-e as a collapsed core/distribution/datacenter switch for a small/medium company (100 persons, ~300 devices, no SAN)?

Can you comment on the reliability and high availability of a dual sup7-e on a single 4510R+E chassis for datacenter workloads?

Thanks.

Re: ASK THE EXPERT - NEW CATALYST 4500E

Hello,

I see the maximum switching of the Supervisor 7-E is 848 Gbps. If the largest chassis is 10 slots and they are 48Gbps each how would you be able to get 848 Gbps of data in to the switch?

Thank you!

Hey Venkat,

Dude, I'm so not going to answer your question here because this is the "Ask The Expert" section.  Go and read your ORIGINAL post.

Re: ASK THE EXPERT - NEW CATALYST 4500E

hi,

Why no one can respond at the question asked by Mr Ian Newman ? :

I  see the maximum switching of the Supervisor 7-E is 848 Gbps. If the  largest chassis is 10 slots and they are 48Gbps each how would you be  able to get 848 Gbps of data in to the switch?

i had the same question ?

Best regards

Re: ASK THE EXPERT - NEW CATALYST 4500E

Hi there,

A 4510R+E you can have 8 line cards plus 2 Sup7e.

The Sup supports 48Gbps per line cards, and each Sup7e can use 20Gbps in redundant configurations. This is for each traffic direction, so you need double that as bandwidth.

So, the total system bandwith will be (48*8 + 20*2)*2 = 848Gbps.

Regards.

ASK THE EXPERT - NEW CATALYST 4500E

Hi,

Been trying to clarify the features; looks like the SUP7-E has not been added as main platform on Cisco Feature Navigator. What I'm looking for is the support of EIGRP on the Universal or IP Base Image. I used the latest available; which is SUP6-E with IP Base.

It mentions of EIGRP stub and EIGRP Support for route map filtering.

While using Route-Map Filtering, features of EIGRP are normally there.

Do we have all features of EIGRP available; if not, what are the limitations?

Thanx and regards,

Ravi

Re: ASK THE EXPERT - NEW CATALYST 4500E

It appears that EIGRP is available fully in the SUP7E, but you have to upgrade to IP Base, then to Enterprise Services.  EIGRP stub routing is available in the IP Base upgrade.  We looked at upgrading from LAN Base to IP Base for certain capabilities, but the license was very cost prohibitive.  The SUP7E uses universal images now and it comes with LAN Base.  You have to purchase IP Base or Enterprise Services to acquire those features.
