What is the case with redundant Sup engine 10GbE interfaces. We can only get one in active state, the other interface stays inactive? Can we have all four interfaces active sharing the backplane?

Are there any plans to support a "shared backplane mode" like on SUP6-E that enables the use of four 10G oversubscripted uplink ports in redundant mode? now there is support for up to two active 10G links in redundant mode.
we have a scenario that consists of a Cisco 4507 series core switch with more than 20 vlans which is connected to a C2960G switch( in a nearby building) using a trunk by a fiber connection. Up to this point everyhting is fine . VTP domain is configured on the core switch and we have all of the 20 vlans present correctly on the edge 2960G wich is part of course of this same VTP domain.the fiber connection goes from core switch to a "in the middle location" where we have a fiber patch panel that is connected in a jumper style to another fiber patch panel going to the destination building where the C2960G sits.
Now imagine that Fiber connection from this middle location to the destination C2960 edge switch is down for any possible reason meanwhile the fiber connection from Core switch 4507 to the middle location is still intact.In the same time, in this middle location , we do have a wireless connection which links 1 Cisco 3750G switche ( a different infrastructure and different VTP domain) to another C3560G switch which sits on the same Room in the nearby destination building where we have the edge C2960G, An idea came to me is to connect one of the fiber port (core) in the intact fiber patch panel coming from Core switch 4507 TO an access vlan configured switchport in the 3750G switch ( this switchport will belong to a vlan designed only to trasmit the vlans on the trunk coming from 4507 core switch say VLAN 10) then connect one VLAN 10 access switchport to the destination C2960 edge switch ( the switchport on the c2960G is still a trunk)Will this solution work and all of the 20- 4507 core switch vlans arrive to the destination C2960G ? Or we do need something that tags the 2 VLAN 10 switchports like switchport dot1q tunnel like QinQ
9x3750E stacked switch (WS-C3750E-48PD-SF0) (15.0(1)SE2 C3750E-UNIVERSALK9-M) 2x10Gbe uplinks from EMC NAS
At a basic level, we have found that the 10Gbe uplinks have slow read performance with or without a port-channel configured (2-3 minutes for a 700MB file to desktop from the NAS) We switched back to testing a 1Gbe and the read speed is normal. Another anomaly is Win7 / 2008 machines read speed is fine from the NAS while the 10Gbe uplinks are in production?!
Write speed is great on 10Gbe. Only read speed is affected!! the switch is not reporting anything abnormal. We looked at SMB/SMB2 as another possible cause...
mls qos is enabled on the switch but not sure if this is affecting performance.
Is the ANY config that I need to carry out on the interfaces to get the read speed working as it should for both Win7 and WinXP. (MTU is 1500 throughout the enterprise, NAS included).
We're looking for Cisco switches with the following attributes to serve as the core switches in a production network:1U (or close), fixed config20 or more 1GbE copper ports4 or more 1/10GbE fiber ports (SFP+)Not ridiculously expensive So far the closest fit we've found for these requirements is the SG500X-24. However, since the SG500X-24 is a "small business" switch we're concerned that the reliability may not be up to the levels of Cisco's enterprise switches, the support level may not be sufficient, the 12MB packet buffer may not be enough to support wire-speed operation (or efficient communication between hosts on 1GbE and 10GbE ports), and so on. But in looking through Cisco's entire current switch line (a daunting task...) this seems to be the switch that best fits the specifications above. So, some more appropriate switch that fits the listed requirements?s why the SG500X-24 would be a poor choice for a production network? Have you had positive experiences with using the SG500X-24 as a mission-critical switch?
What is the correct way to lic VSS on a 4500 SUP7L-E ? url... Under Table 5 - Support by Image Type; VSS is listed as available on IP Base (SUP7E only) and a plain Yes under Enterprise Services, inferring that you need Enterprise Services lic on SUP7L-E to get VSS? url...Under Table 1 - Minimum License for VSS; IP Base or higher (7-E) or special license (7-LE and Catalyst 4500-X)Can find no option on CCO / configuration tools to list a 'special' VSS license for 4500R+E chasiss with dual SUP7L-E and IP Base.How are you meant to purchase/license VSS on 4500E Chassis + SUP7L-E ?
Documentation discusses "1-Gigabit Operation", where all 4 1-Gig SFP's on Sup7L-E are enabled. But it does not say __how__ to select either 10-G or 1-G operational modes.
I upgraded IOS-XE on 4500E (SUP7L-E) to cat4500e-universalk9.SPA.03.03.00.SG.151-1. I encounter the log when i try to issue write mem commad % VRF table-id 0 not activeCompressed configuration from 8947 bytes to 2140 bytes[OK].
I will go to buy a core 4506 but I'm comfusing about the Sup engines and the Fiber module. What is the different between the Sup7 and Sup7L?in the fiber module that I will go to buy is it contain the SFP inside or I have to buy the SFP ( WS-X4612-SFP-E ). also what is the different between the SFP and GBIC?
We are planning for the first installation of 4500 switches containing these supervisor modules. I'm trying to determine the interface numbering convention for ports on the supervisors. Our existing 4500E all have SUP6 modules with twin-gig converters - so I am familiar with the numbering conventions used on those supervisors. How does this change with the software based selection command "hw-module uplink select" used in SUP7?
Any "best practices" or recommendations on how to migrate from a fixed router (3745) to vlan routing on Catalyst 4507 switches in order to minimize the disruption to the network.
I am having a Cisco 4507 switch. The CPU on the switch is running between 50% to 60% constantly. To troubleshoot I collected some logs using debugs & show commands.
debug platform packet all receive buffer show platform cpu packet buffered debug platform packet all count show platform cpu packet statistics show processes cpu sorted | exc 0.00 show platform health show platform cpu packet statistics
show platform health output shows the below process crossing the target value.

What I need to know is, though these process are running in Low Priority, will there be any issue if the CPU goes high due to these process.

We have recently purchased a 5Mbit line with a second ISP and will have the line activated tomorrow. In addition, we recently obtained our AS number through ARIN. How would I configure the second ISP to be used for load balancing/failover?
We will deploy several 4507 with 2xsup7 as a L2 access switches for our office.Does LAN_Base IOS version support SSO or we need purchase IP_Base IOS (L3)?
SSH has been enabled on our one and only 4507 switch for several months and working fine. A few weeks ago the switch had to be reloaded and when it was back online I couldn't SSH to it. When I connected via the console and typed "show ip ssh" it came back saying I needed to generate the keys. Did that and it starting working again. The same switch had to turned off and on the other day due to a power down in the server room and when it came back the same thing happened again!!
The version of IOS is: cat4000-i5k91s-mz.122.20.EW
QoS design problem that I have. I have a client that is deploying new 4507 series switches with SUP6Es. The client will be running lots of voice, streaming video, and video conferencing over the LAN and want to base QoS on Cisco Media net recommendations.
I need to design a new QoS policy with focus on the above media services with basic queuing for critical data services. I have read the Media net design guide and the suggested 12-class model will be too complex to start with but I have seen references to start with a 8-class model with the ability to easily migrate to 12-class in the future. The 8-class model meets all of our requirements but I need to understand how this will work with the 4507 queuing model? [URL]
we have a core switch 4507RE at the data center and 2 departments that connect to it via 10Gig fiber using X2-LRM modules. Each department has a 3 switch stack and both locations are identical w.r.t type and setup scenario.the stack comprises of 1 x 3750E and 2 x 3750G . uplink is from X2 port tengig3/0/1 from the 3750E switch.
All of a sudden dept B started facing problem , where the ping would break and throughput comes around 6 - 7 mbps from that dept to the server behind the core switch. we also noted CRC error on both sides preodically.
we replaced the multimode fiber patch cords, re did the splicing , which stopped the CRC errors to appear.now since morning the uplink port on the 3750E (3/0/1) would suddenly be in "down" state with (err-disabled) as the status when i run sh int ten 3/0/1
and i can also see CRC errors and input errors on the same interface.. if i do shut / no shut .. the port is up and active again.. but this has happned 3 times today.the core swith side is still OK and no CRC / input / output errors are seen..
now on the 3750E i have swapped the 10gig module from 3/0/1 to 3/0/2 . the port is still up but i can see 400 CRC and 500 Input errrors.the module is also OK as i had replaced it with dept 1's module.
Is there a way I can find out the amount of bandwidth i'm using on a particular interface on a 4507 cisco multi-layer switch? It is a gig port and I have it setup for monitoring (spanning) and I see packets being dropped in the "Total Output Drops" area. To me it looks like it must be exceeding the 1gig limit but I don't know a way to check to make sure. I also have the queueing strategy set to FIFO.
We have 4507 distribution switch in our network.I am trying to enable ssh in those switches but seems that ssh command is not supporting. IOS version - cat4500e-universal.SPA.03.03.00.SG.151-1.SG.bin
i have a problem with a cisco cat. 4507 edge switch as when i have a login ssh session to the switch the supervisor engine restart and the redundant Sup. engine becomes the active and so on this problem mainly happen when i have multible SSH session to the switch and it happened very rarely with a single ssh login
the ios version i use is cat4500-entservicesk9-mz.122-54.SG which im using on all my edge switch and they are all working fine excpt this one
I have Catalyst 4507 R-E with one supersor engine n 3 other modules.My question is related to routing of different networks through this switch.I already have certain routes configured which are going to my ISP thru Juniper firewall.(192.168.0.9)I also have Cisco ASA 5510 which i want to use as a backup in case the first one goes down.
I have been trying to reset my Cisco 4507 R-E with sup 10GE engines, and I am not having any luck. I have followed the following document:
[URL]
I have tried "wr erase" and "erase startup-config." I cannot delete the vlan.dat file either. I am using the command "erase cat4000_flash:vlan.dat" and its not working either. I have done these commands several times with no success. When asked if I want to save the config changes, I am answering with a "no" I have not tried to depress the small "reset" button on the front of the sup engines as I read that this just restarts the switch.
