Dear support taem, in cisco 4500 series switch i am getting error interface TenGigabitethernet 1/14 utlization threshold violated.current in traffic 705.228 (70.52 %) and out traffic 707.462 ( 70.75 %) whereas configured threshold is 30 %.
i have checked on switch but qos is there in configuration.
where i need to check if any restriction is there for incoming and outgoing traffic.
and what necassery troubleshooting i need to be done.

This looks like a policy shaping.

Cisco 4500 series switch-Supervisor Engine.

Is it possible to add two different supervisor engine module in a chassis(WS-C4507R+E Chassis)? (WS-X45-SUP7E in slot 3 and WS-X45-SUP6E-
Redundancy in slot number 4)

http://www.cisco.com/en/US/docs/switches/lan/catalyst4500/12.2/31sga/configuration/guide/RPR.html
Redundancy requires both supervisor engines in the chassis to be of the same supervisor engine model (same model, same memory, NFL daughter card and so on), and to use the same Cisco IOS software image.

Cisco MDS series switch details

Hello I 'm new to CISCO Switch world.
I 'm working as Clariion Admin and have have taken up the responsibilty to manage switches.Since,i am a novice i need little guidance on how work on cisco switches.I know the Zoning (how zoning done on MDS 9000 series switches) part ,but would like to venture deep into the details on CISCO MDS series switches.
Like, the use of Port channels etc.
Will really appreciate if some one can help me with a link or place ( not the configuration guide) where in i can find details on concentrated more on the theory part .
Thanks in advance!

Actually the best info is in the configuration guides. There are some external companies that run training sessions on the MDS to provide in depth training. There is the MDS cookbook available on CCO that is also a good point of information. If you search on 'MDS white papers' after you login into Cisco.com, there are several good documents that might meet your needs.
Hope this hels,
Mike

Cisco 500 series switches

Dear support,
Can Cisco 500 series switches deliver 24V on the access port for POE operation?
Best Regards

I belive the 802..2F and 802.2at poe standard is strictly 48v. I haven't found anything to the contrary. There are inline convertes 48v-24v or something like this that can be used with a non poe switch: http://www.digital-loggers.com/poe24.html but that means all conected device would be off the same access port / vlan.

4500 series switches crashing when under load

Dear support community,
We are a small group of network managers and we recently came across a problem in our planned network upgrade considering the 4500 series switches. Six of these switches are configured as VSS redundancy resulting in 3 VSS units connected over double-link fiberoptic port-channels (1+1) building a ring topology.
As soon as we put load (3,5Gbit/s) on one of the port-channels between two VSS, one unit (both main and stdby switches) crashes almost immediately and then reboots. This first happened a few weeks ago, yesterday when testing it happened again but on another VSS connected to the first one. I was able to recover the crashinfo files from both units, they are are attached to this post aswell as the show tech_support output from the one that crashed yesterday.
Unfortunately we don't have the tools and knowledge for analyzing the files and we would appreciate your help. Thank you in advance.
Max S.

Wow. You're running a very old IOS.
If you need to stay with 3.4.X then go with 3.4.5, which is a maintenance release (fixes a few bugs). Read the Release Notes for more information.

4500 Series Switches and 802.1x MAB

My organization has multiple 4500 series switches experiencing the same problem when attempting to authenticate devices via MAB. The issue is that the "show mab interface fax/x details" shows the Client MAC in a waiting status. The device is never sending the switch it's MAC in order to proceed with MAB authentication, so of course the port never forwards traffic. However, if we remove authentication port-control auto the port starts forwarding and the device gains connectivity. Below is the interface configuration command and the MAB details. The IOS version of this current switch is 15.0(2)SG8. Are we missing something special for a 4500 as far as configuration is concerned.
interface FastEthernet8/16

switchport mode access
switchport nonegotiate

authentication host-mode multi-domain
authentication port-control auto
authentication periodic

MAB SM state              = ACQUIRING
Auth Status               = UNAUTHORIZED

hello,
in my organization we have multiple 3560/2960 series switches and some 4500 with MAB.
the interfaces have the following config:
authentication host-mode multi-auth
authentication order mab dot1x
authentication priority mab dot1x
authentication port-control auto
authentication periodic
authentication timer restart 120
authentication timer reauthenticate server
authentication timer inactivity 600

Good luck

Layer 2 trunk ports went down due to cisco 4500 core switch !!!

Hi Everyone,
My 2 Layer 2 2960 switchTrunk Ports went down due to cisco 4500 switch. It happening everytime . I rebbot the switch 4500 . then problem disappears but after sometime facing same issue.
Please help.

My 2 Layer 2 2960 switchTrunk Ports went down due to cisco 4500 switch. It happening everytime . I rebbot the switch 4500 . then problem disappears but after sometime facing same issue.
Hmmmm ... You won't be able to determine anything if you won't provide any addition information. I mean what do you mean by "went down"? Did the port go into "error disable"?
If it went into error disable, console in both switches and post the output to the command "sh interface status err".

Cisco 300 series switches with 802.3at standard

I'm a bit confused as to which of the 300 series switches supports the 802.3at standard. According to the website, the SG300-28P supports it. But in the quick start guide for the 300 series, only the MP models (excluding the SF302-08MP and SG300-10MP) including the SG300-52P has it. Can someone give me a difinitive answer to this? Thanks!

LJ,
P = PoE capable. On the 300 series, half of the ports can provide 15.4W, or all can provide half that.
PoE+ is NOT SUPPORTED.
MP = Maximum Power. This means that all ports can provide up to 15.4W. PoE+ is supported on some models only.
PP = PoE Plus. Can provide up to 30W on a single port. Note the maximum PoE budget for each switch. Also,
half of the ports can provide 15.4W, or all can provide half that - any extra power used by PoE+
MPP = Maximum Power and PoE Plus. This means that all ports can provide up to 15.4W - any extra power used by PoE+
According to the Data Sheet:
"Switches support 802.3at PoE+, 802.3af, and Cisco pre-standard (legacy) PoE. Maximum power of 30.0W to any 10/100 or Gigabit Ethernet port for PoE+ supported devices and 15.4W for PoE supported devices, until the PoE budget for the switch is reached"
The PoE+ models are brand new and are not widey available yet. I did a web search for SG300-28PP and found that at least a few online resellers have it in stock.

Unable to hard code the ports of cisco 3750x series switch

hello,
I have tried with hardcode to 1000 7 Full on the ports which are connected to another switch.
After changing the port to auto from one side of the switch port came up. Is there any solution to make port up when both sides are hard coded to 1000 & full duplex.
Simple Words:
Switch 1 --> Switch 2 --> Hard coded to 1000 & Full --> Down.
Switch 1 --> Switch 2 --> Auto on one end to Switch 1 --> Up.
Switch model:
Switch 1 Cisco 3750x (Gi Switch)
Switch 2 Cisco 3750 (Gi Switch)
Regards,
Ezra.

Yes, it's possible without a straight through cable, enable auto/auto both sides. Otherwise you'll need a cross-over cable.
BTW, if your standard is hard coding copper gig ports, for speed and duplex, you might consider bringing your standard up to date. Copper gig standard went much further in how auto/auto is supposed to work. By disabling auto/auto, I believe, you're also disabling some error monitoring too. Generally, all the major players, e.g. Cisco, would recommend auto/auto for copper gig Ethernet.

Cisco 2960 Series Switch Architecture

Hi all,
I wanted to know if there is a document or an article which describes 2960 series architecture specifically for model WS-C2960-24-S as there is for 2600 series in the following link:
http://www.cisco.com/c/en/us/support/docs/routers/2600-series-multiservice-platforms/23852-2600-architecture-23852.html
Thanks.

Hi,
You should be able to find the information that you need here:

I look forward to a confirmation..

Scripting reboot for Cisco 300 Series switches

I would like to have some help putting together a script for rebooting our 300 series POE switches. I have about 150 at this stage to administer and it would make it much easier not to have to remotely reboot them. The IP settings will be the same for each location and we have about 2-5 in each location. I will be logging in through logmein to each remote server, and will run the scripts from this to the local switches. Any help would be appreciated.

I was playing with my Indigo on an SG-500 and it seems to work. Create a session for each switch and in the session properties for each switch enter your crendentials (user/pass) IP/port, etc, I was using telnet, port 23 for this and then under the send command tab, on connection I entered:
reload
y
One command per line up to 20 commands I believe and it connected, I saw my prompts and replies and then shutting down.
So if you try this you can just go down the file tree list for switches with cameras than need a reboot and restart the entire switch if you like, quick and easy.
You could also add a folder for each switch and a session in that folder possibly for each camera/port with online port number changing for each camera in the session properties and then selectively cycle power for just the affected cameras.
Example for port 22/camera xxxx:
conf t
int gi22
power inline never
power inline auto
It would take a fair amount of time to set up but once done you could just pick a switch folder and the port in that switch to cycle. If you have multiple port on a switch you could use
conf t
int range gi22-24
or
int range gi1,6,16,20
power inline never
power inline auto
might have to verify that syntax

CAT 4500 Series switches Supervisor 6 -E

How is the 320 Gbps Switching Capacity Calculated?
If find this cisco site FAQs
but I have still confusion how it work if someone have very simple and clear connecpt please share
Thanks

Hello Muhammad,
real performance depends from all of the following:
chassis model
supervisor model
linecard types
total figure change widely
see
http://www.cisco.com/en/US/prod/collateral/switches/ps5718/ps4324/product_data_sheet09186a008033a3bd.html
a comparison of supervisors
http://www.cisco.com/en/US/products/hw/switches/ps4324/prod_models_comparison.html
so 64 Gbps can represent a backplane capacity (equivalent to 32 GE full rate they count twice input/output)
48 Mpps stand for 48 millions of packets per second processed.
2)
you need to take in account preamble and interframe gap:
given an IP packet of size S the line usage is given by:
S+18B = L2 frame
total usage = S+18B +20,2B
minimum size is 64 bytes padding is added if necessary
3) traditional linecards connect at 6 Gbps to the backplane but groups of 8 ports share a 1Gbps ASIC this is true up to WS-X4548-GB-RJ45 included
E modules have more performances
The choice of supervisor is dependent on the features you need to run be aware that last supervisors 6E 6LE can have more performance and less features then previous ones.
Hope to help
Giuseppe
