I have encountered some weird issue on our Cat3750 running as DHCP Server.I have excluded 5 IP addresses only on the running configuration. [code]
View 1 RepliesI have a Cisco Catalyst 4506-E Swtich,I configure it as a DHCP and gw for the Wireless Cisco AP through the WLC 5508,the DHCP pool reached the maximum limit I run the Show ip dhcp pool (pool name) it's show the below result

we have a 3560 switch configured with EIGRP with dhcp. We have a user that we cannot ping, however the interface show up / up and no errors on interface. the ip address is 10.2.0.199 - however we have dhcp configured to exclude the range from dhcp ip dhcp excluded-address 10.22.0.1 10.22.0.200 how can this work station get a dhcp address if we have that ip range excluded from the dhcp pool?
The user is off a different switch that is a uplink to this distribution switch. Traceroutes shows that the problem is with the distribution switch.
We have upgraded our gateway router from a Cisco Linksys RVL200 to a Cisco 861, this is a big jump from a GUI driven system to IOS CLi and i'm having issue finding my feet. I tried the Cisco CP system but it didn't work so I'm going to configure it with IOS commands. I wish to replicate the current configuration on the 200 with the following setup.
I have created a DHCP pool but i am unable to configure the FastEthernet ports to hand out address automatically, the pool is called USERS with range 192.168.1.30 -> 192.168.1.253.How do I work out the client-identifier for a DHCP client, I don't want to plug this into the network and manual reconnect all the PC's just to get the ID then make a static route.
I've just noticed an error I've never seen before in our switch logs. We have a stack of 6 Cat3750G-48TS-E switches. The first two in the stack have been up for just over a year and I've only just noticed this error. Thus far, I haven't noticed any symptoms - I just stumbled upon this error while checking for something else.
As far as I can tell, this has only popped up once and it was 2 days ago. Unfortunately, due to an incorrect firewall rule, our syslogs were not getting to our syslog server so I don't have any historical logs to check against, but it hasn't happened since.
The error I've seen is as follows:-
Jun 5 17:04:03.288: * ManagementInterfaceInitialized exception in port-asic 0 (N16FujitsuSwitch.com.au-2)

I found increasing number of overrun in the tengigabit interface. The hardware is 6509 with sup720-3B and the overrun output is shown in WS-X6716-10GE module. The connected device to WS-X6716-10GE is EMC Islion S200. I think the capability of WS-X6716-10GE can handle EMC NAS device and the load is not so busy. So I have no idea of handling this and the reason why this overrun packet is shown.

View 1 Replies View RelatedI have "inherited" a Catalyst 4506 with IOS version 12.2(20)EWA1 and Supervisor IV already installed. We recently purchased a second Supervisor IV and I am looking to install this second supervisor for redundancy. Is there anything special with installing a second supervisor or so I just physically install the new supervisor and the IOS will automatically set everything up?

I have 2 SG300 switches, in layer3 mode, lag'd together for high availability, serving 2 Dell R815's and a Dell Equallogic 4100 for virtualisation. I have setup a number of vlan's, network traffic, mgmnt traffic, iScsi, vMotion etc and they seem to work.
However, Equallogic unit suddenly became unavailable to view for managment yet maintained iscsi traffic for the servers ok. After much head scratching, noticed that one of my SG300's had the vlan ports assigned to various vlans had *automagically* changed there assignment, ie tagged changed to excluded, but only for one of the iscsi traffic connections and the mgmnt port, both coming from the Equallogic, the other iscsi continued its assignment fine. The other SG300 hasn't changed. Guaranteee no one has been into change it and no changes have been made to Dell servers or Equallogic.
Q. Is there any circumstance where the switch can change the port setup itself? or is there any external circumstance that would trigger that change either?
This has now occured twice. The setup is running as a test lab, not in production until all setup is complete, then it will replace our existing harware.

I want upgrade IOS on my 7206VXR from 12.4(12c) to 15.1(4)M5 , but the CF card only 64M.
-NAME: "disk2", DESCR: "64MB Compact Flash Disk for NPE-G1"
-Router#show bootvar
BOOT variable = disk2:c7200-jk9s-mz.124-12c.bin,15.1(4)M5 is almost 40M. So there is not enough space.I want to ask is it ok if I upgrade with normal precedure , With the command " copy tftp: disk2: " ?Does the router will automatically delete the older IOS first and then copy into the new one ? Or Is there something I should pay attention first ?
I Have a problem I'm trying to configure automatically my switch over ther DHCP when I start the switch it request an IP from the DHCP from here everythings is fine but it does nothing more,indeed I put on my dhcp the option 66 and 67 which is an adress of my TFTP server and a file to download and the switch seems not to understand theses options , I tried my dhcp with a cisco airport and everythings works fine the File from the TFTP is automatically downloaded into the airport...There is an option to add or am I missing something in order to make it work with my switch ?
My switch : Catalyst 2960IOS VER : 12.2(55)SE5
I have a scenario where 15 c500 switches and 5 2960 8 port switch connected to 4507R core switch. There are 10 dhcp pools created on the 4507.
Eg: ip dhcp pool XXXX
network xxxx.xxxxxxx
default-router x.x.x.x
Now the default router is directed to vlans created on the switch i.e vlan 101, 102, 103 and so on. Now the remaining switches connected are configured to be in the same vlan. So the systems connected to the edge switches will get the DHCP ip automatically, Now my problem is after sometime (may be 2 or 3 hrs) all the edge switches are losing configuration automatically even though it's not restarted, even after saving the config on to nvram, everytime I connect the console and check all the saved config is lost?
I coulden't visit any websites and it gave me an "error 105" something. So i tried connecting my other comp to the internet cabel with the same result. So i tried to find a solution on the web (wierless internet still worked) and stumbeld upon a similar problem were the answer was to manually fill in an adress in the "internet protocol version 4" properties in the "local area connection" properties. I then noticed that i dident have the "Obtain DNS server address" set to automatically and that the other manual boxes were empty. I then turned the auto on an i had access to internet. Is this safe? Cause i read somewere that DNS server addresess were provided by the company that provide you your internet service, and that you can be redericted to a fake website that can get a hold of your account information on it
View 1 Replies View RelatedI would like to update the device package for Cat3750. The readme file from update package says that DtShare V1.10 (DtShare.cv50.v1-10.zip) has to be installed first. I have actually DtShare V1.9 installed but there is no DtShare V1.10.
When I execute the device update, than it downloads everytime the DtShare V1.9. My question to Cisco staff and all other CW specialists: How can I become the DtShare V1.10?
I have a 3750 stack of 4 switches that was installed about 2 years ago. Recently I was doing some work on the switch and realized that I am unable to save the config.

View 3 Replies View RelatedI currently have Netflow enabled on all of my routers in my network. However, I have a Cat3750, which does not support Netflow. The 3750 is at a larger remote site and I need visibility into the traffic that is traversing internal to that switch. All VLANs are configured on the 3750. I have an extra Cisco router, which I have theorized I could use as a Netflow probe.
The 2811 Router has to FastEthernet ports.F0/0 would be configured with no IP Address and would be connected to the 3750 on G0/1 with no VLANs configured.F0/1 would be configured with a static IP and connected to the 3750 on port G/02 with the appropriate VLAN to ensure network connectivity.
On the 3750, configure a monitor session with a destination of Interface G0/1.On the 2811, configure netflow to sent to the Netflow server and set F0/0 for ip flow ingress.Obviously, it doesn't work. But I cannot figure out why.
Is there a way to change the timeout for the Client Excluded: MACAddress status? It seems like the exclusion is rather short. I'd like to have the ability to control the exclusion time. Using WLC-5508 7.0.116.0.
View 2 Replies View RelatedHave issue with iPhones and other smart phones being considered as excluded clients for the reason of Identity Theft? I am looking at one of my controllers and there are almost 680 excluded clients and most of them are smart phones and they are all being excluded for the same reason. It seems to be mostly iPhones but not all of the iPhones are experiencing the same behavior.
There is a mix of AP types (AP1010s, 1131s and 3502s) and also a mix of controller types (44XX and 3508). I have not been able to find any information to explain this behavior on the phone side and/or the wireless side.
This is my first time trying to configure a WAP for out network. I have an AP1141 connecting to an SG300-28 switch. The subnet for my WAPs is 10.10. 40.0/ 24. The rest of my internal network is 10.10.10.0/24. There are four other WAPs on the 10.10.40.0/24 network that I did not configure. When I assign an IP address - 10.10.40.7 to my WAP with the gateway as 10.10.40.100 (router), I cannot ping anything. If I assign the WAP an IP address - 10.10.10.192 with the gateway 10.10.10.100 (router), I can ping everything.
View 6 Replies View RelatedI disconnected and reconnected the powercable while holding on to the setup button until system, alert, setup go amber. The system led light began blinking green. I waited until one of the leds lights on the ports starts blinking green I then connected the ethernet cable connected to my pc. I made sure my lan connection on my computer was set to dhcp.In the docs claim it should take about 1 minute to grab a new ip address. After a few minutes i check the ipconfig on my pc and I get the apipa address.The setup light on the switch remains green while system is amber. The led for port 1 stopped blinking and remains green.My pc is not grabbing an ip address I don't know what else to do.
View 7 Replies View RelatedWe have a Router with one External IP and a couple of VLANs. We have got a Teleconferencing Unit that needs almost every port known to man to work, so decided to get the unit its own External IP.
We have the IP now and how to get it in the router and then also to use it only for the Video unit (From outside straight through to Video).
Im comfortable adding lines to the router but just don't know what the lines should be.
The new IP's purchased are 116.199.222.200/30 (Only need to use one address, lets say 116.199.222.200). No idea what the subnet mask should be...

View 3 Replies View RelatedI'm fairly new to Cisco configuration and I am looking at a problem for a client that involves the use of a Cisco 887 (wired only) as the main router/gateway. The problem I am investigating involves the allocatoni of DHCP addresses from the device to a product we have designed that connects to the router. I am attempting to set the 880 up on the bench with no ADSL connection and just use the DHCP feature of the box for the 4 switch ports on the back. I have tried all kinds of configurations from default. Whatever I do I can't get the router to assign an IP address to anything that is plugged in (Windows or Linux machines). What could I be doing wrong ? It can't be that difficult to get the system to just act as a DHCP server.

View 13 Replies View RelatedI would like to enable port security to hardcode the MAC address on the ethernet switch. There are 5 ethernet ports in the same ethernet switch to be assigned for one person (one note book), e.g. port 5, 6, 15, 16 and 23. The model of ethernet switch is cisco 2960S and one MAC address is configured on 2960S.
1. Does 2960S support this requirement to allow input the same MAC address to 5 different port?
2. If yes, can ethernet switch "smart" enough to forward the packages to "active" ethernet port which is connected to notebook and the rest of four ports are inactive.
3. if no, any solution or any work around to achieve this requirement
