Bandwidth and delay parameters in cisco switch

Hi all ,
Is the delay and bandwidth parameters are configurable in the switch interface ?
Actually In one of the Fa interface the delay is showing as 100 , in another interface output delay is showing as 1000. Even bandwidth is showing 100000Kbit and one 10000.
Kindly suggest.
Thanks,
Regards,
Vijay

HI Vijay,
Delay:
It is related to interface speed . The interfaces are 10/100/1000 capable. Depending on the negotiated bandwidth the default delay changes. Switchport/routed port has no effect. If you leave them "auto negotiated" then essentially the delay negotiates to match the port speed as per the below:
1Gbps = 10usec
100Mbps = 100usec
10Mbps = 1000usec
*** Note: important to note that changing the "bandwidth" statement doesn't change the negotiated "delay". Only the "speed" will change delay... but please note that changing "speed" command is potentially network impacting. The "speed" command changes the literal interface capabilities for negotiating link speed, whereas changing "bandwidth" and "delay" changes an imaginary representation of link throughput capabilities.

Pb bandwidth and delay

Hi,
I'm facing an issue since i change my SDSL operator (4Mbits/s).
When someone dowload something, all the bandwith is use and the delay increase... and it's slow !!!
I have only web browsing and FTP, no Voice!
I think i must limit the use of bandwidth to have a stable delay.
So, i try QoS, limit bandwith, auto Qos discovery but it doesn't work and i'm nt sur to implement them correctly.
My skills in network, espacally in cisco configuration are poor.
I need help

I recently change my SDSL operator and now i'm facing issue with delay and bandwidth.
This is a ping to www.google.fr, you can see the delay pb :

Audio Video Bridging on Cisco Switches

Hi All,
I'm looking to implement AVB (IEEE 802.1AS, 802.1Qav, 802.1Qat and 802.1BA) on Cisco switches. I've searched on these forums, Cisco's website and google for any information there might be about AVB support on any Cisco switches. The closest I've come to finding information is some slides that state plans for AVB implementation on some blades for the 4500E series switches there are some other features from the same slides that have been implemented but there is no word on AVB implementation. Has anyone else heard anything about the implementation of Audio Video Bridging?
Wiki Page for AVB
Thanks in advance,
Cory

Hi,
Catalyst 4500E is expected to be hardware-capable of supporting AVB by late calendar year 2013. Other switches, e.g. Catalyst 3k, other 4k series and 6500, only mentioned AVVID support, nothing about AVB.

Tacacs-server key working in some Cisco switches for AAA, but not in other switches???

Good day,
Has anyone experienced this before? I am using Cisco ACS 5.2. I have a very simple word (no, not cisco ) for my tacacs-server key. I've used the same key within the ACS and on two other Cisco switches, and AAA is working fine between the two switches; however, in setting up the key via the ACS and on a third Cisco switch and using PuTTY, I'm getting the error of "Access Denied. Using keyboard-interactive authentication."
I've re-entered the simple tacacs key multiple times within the ACS and on the switch making sure to not fat finger or misspell it.
I don't think there is a problem with the AAA setup I have within the switches as all of the AAA configs are the same on every switch we have.
Any other possible ideas anyone can suggest?
Cliffs:
-tacacs-server key is a simple key and is the same for every switch and within ACS
-AAA config is the same on every switch, so I do not believe it to be a AAA config issue
-Running config on switch that is not working is pretty much the same as the other two working switches
Any advice is greatly appreciated.
Thanks,
Y

Hi, and thank you for your reply back; however, when I got into the Authentication logs, I see nothing, like it's not even logging the failed attempts.

Management port in Cisco Switches (are they really physical port)

Hi all,
I have been taught to console into my cisco switch for configurations through console cable + putty (serial terminal).
Then I have been taught to configure a management ip and gateway on the cisco switch.
Switch# conf t
Switch(config)# interface vlan 1
Switch(config-if)# ip address 192.168.1.11 255.255.255.0
Switch(config-if)# no shut
Switch(config-if)# exit
Switch(config)# ip default-gateway 192.168.1.1
All the while, i thought this is the way to remote in to the switch via putty/telnet through the network to configure the switch, until i saw the picture below (cisco catalyst 2960)
=======================================
There is a physical port call ethernet management port. What is it ? What is the difference between this port and the earlier example of setting a management ip in VLAN 1 ?
If i set an IP on this particular interface and I ssh in, will i see the same screen/display/console from the earlier example in which i set a management ip in VLAN1 and I ssh in ?
Regards,
Noob

Hi Leo,
Sorry if you find it hard to explain to me.
I have understood to think of the ethernet management port as a separate entity from the original switch.
Maybe with the help of the diagram below, can you let me know if i have understood correctly ?
*please assume connected port is a management port separated from the normal switch ports
q1) does the ethernet management port need to be connected to another switch ?
I have thought of it as a device on the network and it is mentioned by you previously that it will be connected to a switch
"he traffic goes up the cable connected to the Management port and up a switch. Now that switch holds all the information because it is a switch. "
q2) In the current setup then, terminal B will be able to access the management port - am i right ?
q3) you mentioned that the management port is not able to set any gateway, (which is the router fe0/5 - 192.168.0.3 in my illustration), in that case do you mean that terminal A will not be able to access the management port remotely and it can only be accessible locally ?
Please do correct me if my understanding is wrong.
Thank you so much for your advices.
Regards,
Noob

Connecting " HP Blade System C7000 enclosure" to Cisco Switch

Dear
We moved our data center from on place to another .The network cabinet includes " HP Blade System C7000 enclosure". we have two vlans , one of them is DMZ. In the old place , the HP Blade was connected to two Cisco switches ,on one of them DMZ port was configered and on the another Cisco switch non-DMZ port was configured .Now our " HP Blade System C7000 enclosure" use one CISCO switch and the DMZ and non-DMZ ports are configured on the same CISCO switch and when we restart any server from any vlan ,the server will not be able to connect to the network although all of the servers have static IPs.
and after logon to the server , a message appears telling us there is a conflict with the mac address of the gateway. the same mac address conflicts when restarting any server from any vlan.
Would you help?
Thanks

Hello, David.
Your command doesn't work because it's made only for tha ports that has command "spanning-tree portfast" in them. Try change spanning tree mode at the HP switch to MSTP if this is possible.

Cisco switches and virtual ip address(load balancing address) on xenapp portals

Hi I am quite new in configuring cisco switches and stumble across an issue after installing xenapp7.6 with load balanced portal to the ddc`s
It seems i only can ping or get access to portal if using real ip address behind cisco switch from other subnets in my network.
I can ping ddc01 and ddc02 and connect to the portal with http without problem. However when i triy to access the load balancing address of the ddc`s
it wont answer to ping or http
In same subnett it is no problem connecting to the load balancing address of the ddc`s, but in loactions on other subnets i only can access real server ip
eks
dd01 192.168.1.4 ok ping and access behind cisco switch from subnets
ddc02 192.168.1.5 ok to ping access behind cisco switch from subnets
load balancing for both ddc 192.168.1.6 not able to get answer og access from subnets, only in same subnett
Is there any way to configure switch to access the load balancing address of the ddc`s ?

Arp table and mac table in cisco 4503 switch

Hi all,
I have a problem with 4503 switch
I have 7 highend servers in my lan i.e 5hp and 2dell servers.
Each server has 4 network interface cards(1g). so 7*4=28 ports.
I have create vlan 70, ip add is 10.70.70.1
I have assign ip address to servers like
first server         10.70.70.2, 10.70.70.12,
Second server   10.70.70.3, 10.70.70.13,
Third server        10.70.70.4, 10.70.70.14,
fourth Server       10.70.70.5, 10.70.70.15, 10.70.70.25, 10.70.70.35
fifth server           10.70.70.6, 10.70.70.16, 10.70.70.26, 10.70.70.36
sixth server          10.70.70.7, 10.70.70.17, 10.70.70.27, 10.70.70.37
seventh server      10.70.70.8, 10.70.70.18, 10.70.70.28, 10.70.70.38
The problem is in four interfaces each server, only one or two interfaces are pinging, remaining interface are not pinging.
for example in the first server i can able to ping 10.70.70.12- macid 60eb.69d2.a2aa
                                            i can't able to ping 10.70.70.2- macid 60eb.69d2.a2ab
second, fourth, fifth, sixth, and seventh continiously pinging successfully.
for example in fourth server i can able to ping 10.70.70.5 macid -b499.bafe.9c98
                                         i can able to ping 10.70.70.15 macid-b499.bafe.9c98
                                         i can able to ping 10.70.70.25 macid-b499.bafe.9c98
                                         i can able to ping 10.70.70.35 macid-b499.bafe.9c98
now you understand what is the problem, which server i am not getting pinging that arp table shows each interface separte mac address
                                                   which server i am getting pinging that arp table shows each interface bind with same mac address(dynamically)
Please give me the solution

Hi,
I Think you need to do Teaming on the servers.
++ configure etherchannel between switch and the server.
configuring etherchannel b/w 4503 and server:
================================
http://www.cisco.com/en/US/tech/tk389/tk213/technologies_configuration_example09186a008089a821.shtml
Sample NIC Teaming - HP NICs with Cisco Switches (EtherChannel) :
==============================================
http://support.citrix.com/article/CTX434260
There are several NIC teaming technologies available today from switch vendors. Cisco uses the term “EtherChannel.” Various switch vendors use various terms, and these may or may not provide the same exact functionality. Use of EtherChannel technology requires support from the server hardware vendor, NIC vendor, and Layer-2 switch vendor.
Hope this helps

Converged 10gig server adapters and Cisco switches

I have little network with 4 vsphere servers connected to clustered 3750x with 4*1Gig NICs per server.
Servers are connected to central storage with two 8Gbps FC links per server. I don’t have FO switches cause central storage is equipped with 4 FO ports per controller.
I want to upgrade servers and central storage. Servers will have two converged 10gig (HP FlexFabric) and 4*1 Gig interfaces
I need to upgrade 3750x switches with new one with 10 gig interfaces.
I am looking for two new Cisco switches that can handle converged traffic from server 10gig interfaces (iSCSI, FCoE).
Nice feature will be if it is possible to connect existing FC storage to the new switches.
Kind regards,
Vice Lacmanovic

Hello, vlacmanov.
I recommend at least the Nexus 5000 to support iSCSI and FCoE over your 10GE interface. (http://cs.co/9001SoyL) Do you already have any existing Cisco Nexus on your network?
Let me know if you have additional concerns or e-mail ([email protected]) me directly. Kind regards.

Which CISCO switch supports SFP, SFP+ and 10G ethernet ports

I would like to have information about a CISCO switch which can support fiber ports SFP(1g) and SFP+(10g) and copper 1g and 10g ethernet ports. And will it also software upgradable to support L3 protocols ?

You can choose from the Cisco 3560-E, 4900, 4500, and 6500 series switches. That's in order of capability (and cost!), from least to greatest.
The 3560-E and 4900 series are fixed chassis systems (the 4900M is semi-modular) while the 4500 and 6500 series are completely modular - buy the chassis and populate it according to your requirements.
In addition to the references cited above, also refer to the Cisco Products Quick Reference Guide (CPQRG), available at http://www.cisco.com/en/US/prod/qrg/index.html
Hope this helps. Please rate this post if it does.

Cisco switches and 802.1.x

I have a question for you.
Cisco all switches, is it impossible to present for 802.1x ?
I try to put a network access server in our network to authenticate.

Most Cisco switches will handle 802.1x, but it depends on the switch and the OS. Which specific ones are you considering?

Cisco 5 port and 8 port gigabit unmanaged switches

I am looking for 5 port and 8 port gigabit unmanaged switches in Cisco. Please provide the BoM for the same. As per my understanding the following switches can suffice the requirement (SG100D-05 and SG100D-080) however I am not sure about the DC power, whether they can be used in normal AC environments.

The SG100D-05 and SG100D-08 are too small and their power requirements are too low to justify building an AC power supply into them like the larger SGx00 switches have, so they are wired to accept DC power and use an external power adapter (included) for connection to an AC environment.
There are really no optional components to these devices, so the BOM would be as follows:
5-port SG100D swich: SG100D-05
